A dryer control board is the printed circuit board that reads the buttons, runs the cycle timing and switches power through to the motor, the heater and the valve. It is the most expensive electronic part in the machine and the last one you should suspect, because almost everything it controls can fail on its own and produce exactly the same symptom. A dead panel, a cycle that will not start, a machine that runs and never heats — all three have cheaper, commoner causes sitting between the board and the thing that stopped working.
That ordering is the whole point of this page. A board is not a part you fit to find out. If you order one on a guess and the fault was a door switch, you have spent the most money available on the problem and still have it. The four checks below cost nothing, take about ten minutes, and they eliminate most of the reasons a board gets blamed.

What the board switches, and what it cannot be blamed for
Think of the board as a switchboard with a clock attached. It does not make heat and it does not turn the drum. It decides when the motor relay closes, when the heater circuit is energised and when to stop, based on what the buttons said and what the sensors report back. Everything downstream of those relays is a separate component with its own way of dying.
That distinction decides what a board failure actually looks like. If the drum turns but there is no heat, the board has already proved it can read the panel, close the motor relay and run the cycle — so the fault is far more likely to be in the heat circuit than in the thing that commands it. Whirlpool’s own documentation makes the same split from the other direction: on an electric machine, the dryer runs on a 30-amp circuit fused on both sides, so “there will be 2 circuit breakers to operate the dryer. One circuit will operate the motor (turning the dryer drum), while the other circuit will operate the heating element. If one of these is tripped, the dryer may not heat.” Half a tripped double-pole breaker produces a dryer that tumbles and never warms up, and there is no board in that story at all.
The reverse case is just as misleading. A machine with no lights and no response to any button looks like the board has died, and it is usually the supply, the door switch or a thermal fuse that sits in the control circuit on some platforms. Dryer won’t turn on walks through those three stages in order, and it is the page to read before this one if your panel is completely dark.
Four things to rule out before you order a dryer control board
Power on both legs. An electric dryer is fed by a double-pole breaker. If one pole has tripped or a terminal screw has loosened at the block, the machine gets 120 volts where it expects 240 and behaves strangely rather than dying cleanly. Whirlpool’s instruction is to unplug the dryer first and then check that the terminal screws are tight — not to poke at a live block.
The documented reset. Whirlpool publishes one for its dryers and it is not the five-minute unplug people repeat from the washer pages: “Power unit down by turning off the circuit breaker(s) for one (1) minute. Power unit up by turning on the circuit breaker(s). Start a time dry cycle. Monitor the dryer for one (1) minute to ensure the error code does not display again.” A reset is not a repair — if the same condition comes straight back, you have learned something real rather than failed. That is the useful version of a power cycle.
Control Lock. Maytag and Whirlpool both ship a lock that disables the panel deliberately, and it survives being switched off. A machine whose buttons beep and do nothing is doing exactly what it was told. Hold the marked button for the dwell your panel prints, usually three seconds.
The door, both latches. A dryer that lights up and will not start is usually telling you the door circuit never closed. Whirlpool notes that some models carry a top and a bottom latch and both must be secure. Press the door firmly shut and listen for the switch, then try Start again.
If you get through those four and the machine is still wrong, the next question is which error it is showing, because that narrows the field faster than any component test. Dryer error codes sets out what each brand actually publishes — and Whirlpool’s own list is blunt about where the line is: a code “alternating between F# and E#” means “the dryer control has detected a problem that requires service”, which is the manufacturer saying the board has found a fault rather than being the fault.
Read the number off the board, not off a parts diagram
This is where most wrong orders happen, and it is entirely avoidable.
Start with the plate. Whirlpool documents the location for every machine it makes, and on a dryer it is inside the dryer door, on the rim of the opening. On a ventless heat-pump machine it is behind the water tank; on a stacked laundry centre it is on the inside of the dryer door; on a pedestal it sits on the storage drawer, inside or outside wall. Whirlpool hedges the guide as “the most common locations”, so if the rim is blank, check the rear panel and the back of the console. Photograph the plate. Do not work from memory and do not work from the box the machine came in.
Then get the number off the board itself. The console comes off with a handful of screws on nearly every chassis, and the part number is silkscreened or stickered on the board — usually a long alphanumeric starting with the manufacturer’s prefix. That number beats the model number, because manufacturers revise boards mid-production and two machines with the same model code can carry different revisions. Photograph the board in place, with all the connectors attached, before you touch anything. You will want that photograph when you are reconnecting twelve plugs that all look alike.
The third thing to note is the chassis. GE’s current main board is sold as a board and chassis assembly, so you are replacing a tray with electronics on it rather than a bare card. Samsung and LG sell the bare board. That changes what arrives and what you have to transfer across.
One more habit worth adopting: touch the bare metal cabinet before you take the new board out of its bag, or wear a grounding strap. Static is the one way to kill a board between the courier and the console.
One board can replace nine old part numbers and still not fit yours
Supersession is the single most confusing thing in this category, and understanding it is what stops a wrong order.
Manufacturers consolidate. When a board is revised, the new number officially replaces the old ones, and the listing says so. GE’s WE22X35978 names nine superseded numbers on its own listing — WE04X23887, WE04X25474, WE04X28457, WE04X29097, WE22X30157, WE22X31717, WE22X31719, WE22X32937 and WE22X32939. That is genuinely useful: if the number on your board is any of those nine, the current board is the one you want.
What supersession does not mean is “fits anything with that brand on the front”. The same GE listing names specific compatible models — GTD58EBSV0WS, GTD65EBPL0DG, GTX65EBSJ0WS, YTD74E2SN0WS “and others — when confirmed for fit”. The qualifier is doing real work. A board designed for a platform will physically mount and electrically plug into machines on that platform only, and a brand is not a platform.
One of the listings below puts the warning more bluntly than we would dare to: “It will NOT work if you order a wrong part… Please do NOT order parts by looks or measurement. Most of the time they will not work or fit.” That is a seller talking themselves out of returns, and they are right. Two boards can be the same size, the same colour and carry the same connector shells while running different firmware and a different relay map.
Kenmore deserves its own sentence here because it causes more mismatches than any other badge. Kenmore does not make dryers. A 110 prefix is Whirlpool, 796 is LG, 417 is Frigidaire and 402 is Samsung. Read the first three digits of the Kenmore model number and shop the platform, not the badge.
Boards by platform: Samsung, GE, LG and the Whirlpool family
Each of these is an example of a board for one platform, with the compatibility its own listing states. None of them is a universal answer, and the only thing that decides which one you need is the number on your old board.
GE WE22X35978: board and chassis as one assembly
GE’s current main control board arrives as an integrated board-and-chassis unit rather than a bare card, which makes it the easier of these to fit — the mounting geometry comes with the part instead of having to be transferred. GE describes it as controlling “all major dryer functions, from motor and heater to sensors”.
Which machines it covers: GE dryers whose existing board carries any of the nine superseded numbers listed above, with GTD58EBSV0WS, GTD65EBPL0DG, GTX65EBSJ0WS and YTD74E2SN0WS named explicitly and other models in the same family covered when confirmed. Access is through the control panel.
What it does not do: it will not fit a Hotpoint or Kenmore chassis just because GE built it, and it will not resolve a fault that was never the board. Check your existing number against the supersession list before ordering — that list is the compatibility statement, and if your number is not on it, this is not your part.
Samsung DC92-01729Q: the genuine OEM main board
This is Samsung’s own part rather than an equivalent, described by Samsung as the board that “manages the functions of the dryer such as drying time and temperature”. It is the main board, not a sub-board, and it is supplied as a bare card.
Which machines it covers: Samsung dryers only, across the model family that calls for DC92-01729Q. Samsung’s own listing advice is the right standard and worth repeating — refer to the service manual or the manufacturer “to validate the needed part number for your appliance prior to purchasing”. Note that Samsung also sells DC92-01729Z and DC92-01896G, which are near-identical in name and belong to different machines.
What it does not do: nothing about an OEM board makes it more likely to be your fault. If your Samsung is showing a code, look it up before you buy anything. This listing is currently marked as having only a few units available, so treat it as a named option rather than a guaranteed one.
LG EBR76519513: the LG main board
LG’s genuine main control board for the dryer families that use it, again handling cycle timing and temperature control. LG is the quietest of the four manufacturers about cross-compatibility, so the number is all you have to go on — which is actually the cleanest situation, because it removes the temptation to guess.
Which machines it covers: LG dryers calling for EBR76519513, and that includes Kenmore machines with a 796 prefix, because those are LG-built. If your Kenmore starts 796, the LG part catalogue is the one you are shopping.
What it does not do: it is not a repair for a machine that has never been diagnosed. LG publishes an error-code list, and a code that names a sensor or a motor is not pointing at this part. This listing also shows limited availability at the time of writing.
W10111617 for the Whirlpool family: one board, a long model list
This is the Whirlpool-platform board, which means Whirlpool, Maytag, Amana, Roper, Estate and Kenmore 110 machines of that generation. The listing names its supersessions — WPW10111617, 3978983, W10067050, W10074280, W10111608, W10111610 and W10118244 among them — and then prints the compatible model list in full, which is exactly the behaviour you want from a parts listing.
Which machines it covers: the listing names Kenmore 110.67032600, 110.67042600, 110.77032600 and the rest of that block, plus Maytag MGD6300TQ0 and MGD6400TQ0 and Whirlpool WED6200SW0, WGD6200SW0 and WGD6400SB0 variants. If your model is on that list, this is a direct fit. If it is not, it is not a near miss — it is the wrong part.
What it does not do: this is a manufacturer-authorised equivalent rather than a Whirlpool-branded box, and the seller’s own warning about ordering by appearance is the most useful line in the listing. There is no way to tell these boards apart visually, so do not try.
When a board is worth more than the dryer
This is the part the parts sellers leave out, and it is the most valuable thing on the page for some readers.
The control board is the most expensive single component in a domestic dryer, and the two sensible reference points are both unflattering. Consumer Reports advises replacing an appliance more than eight years old rather than repairing it unless it is a high-end machine, and the trade’s rule of thumb is that a repair costing more than half a comparable new machine is not a repair worth doing. A board on a twelve-year-old dryer clears both bars in the wrong direction. Dryer repair cost sets out the published figures and what each one actually counts, and how long should a dryer last gives the federal lifespan figure to measure your machine against.
There is also a quieter case against buying. If the board failed because something else cooked it — a shorted heater, a seized motor drawing locked-rotor current, moisture from a leaking vent joint running down the console — then a new board goes into the same conditions and fails the same way. Find out what the old board was asked to do before you ask a new one to do it.
FAQ
How do I know it is the control board and not something cheaper?
By elimination, not by inspection. A board rarely looks faulty: burnt relay contacts and a scorched trace show up occasionally, but most failed boards look perfect. Work through the free checks first, then establish which circuit is not being switched — if the motor runs and the heater never energises on an electric machine, check both breaker poles and the heat circuit before suspecting the relay that feeds it.
Can I just swap the board and see?
You can, but it is the most expensive diagnostic available and it is usually not returnable once fitted. Electronic parts are frequently sold as non-returnable for exactly this reason. Spend the ten minutes on the free checks instead.
Where is the model number on a dryer?
Whirlpool documents it as inside the dryer door, on the rim of the opening, for a standard dryer; behind the water tank on a ventless model; inside the dryer door on a stacked laundry centre; and on the storage drawer for a pedestal. Other brands put it in similar places, often with a second plate on the rear panel. Photograph it rather than copying it out.
Does the part number on the board matter more than the model number?
Yes. Manufacturers revise boards mid-production, so two machines carrying the same model code can need different boards. The number printed on your existing board is the authoritative answer. The model number is what you use when the old board is unreadable or already removed.
My Kenmore dryer needs a board. Whose part do I buy?
Read the first three digits of the model number. 110 is Whirlpool, 796 is LG, 417 is Frigidaire, 402 is Samsung. Kenmore is a badge, not a manufacturer, and shopping for a “Kenmore board” without resolving the platform first is how people end up with a part that will not plug in.
Is a used or refurbished board a reasonable option?
It is a real option on an older machine where a new board is hard to justify, but understand the trade: you are buying an unknown number of remaining service hours with no warranty and no way to test it before fitting. If the machine is old enough that a used board looks sensible, that is also a signal worth listening to about the machine.
Photograph the board before you order one
The sequence that works, in order: check both breaker poles, run the documented one-minute reset, clear Control Lock, confirm both door latches. If the machine is still wrong, take the console off, photograph the board with every connector still attached, and read the number off it. Match that number against the supersession list on the board you are considering, and against your own model number from the door rim.
If the number on your old board is one of the nine GE supersedes, the GE board-and-chassis assembly is the direct replacement and the easiest of these to fit. If you have a Samsung or an LG, buy the manufacturer’s own part against the number on the board and nothing else. If your plate says Whirlpool, Maytag, Amana or Kenmore 110, find your model on the list and check that it is there rather than nearly there.
And if the dryer is past eight and the board is the fault, the honest answer is that you are putting the most expensive part in the machine into the oldest machine you would put it in.
