On an automatic or sensor cycle, a dryer timer not advancing is the design working, not a part failing. That number is not a timer. It is an estimate the dryer recalculates from how wet the load still is, and it is allowed to stall and allowed to go up. The genuinely broken version exists, but it is the minority case, and one minute tells you which you have.
This is the opposite complaint to a machine that stops too soon (dryer keeps shutting off).
On a sensor cycle, a dryer timer not advancing is the design
Two completely different things live behind the same display. On a Timed Dry cycle the dryer counts down a fixed duration, and that number is a real clock. On an automatic or sensor cycle it is reading moisture sensors in the drum and showing a prediction of when the load will reach the dryness level you chose.
A prediction updates. If the load turns out wetter than the first guess, the estimate stops falling, or climbs. Nothing has failed — the machine has revised its own answer with better information than it had thirty seconds ago. The frustrating version of this search is not a timer problem at all: it is a machine correctly reporting that the clothes are not dry yet, in a format that looks like a countdown and is not one.
Maytag documents the number going up, not just failing to move
A manufacturer has a whole support page about this, which is the strongest evidence it is normal behaviour. Maytag’s wording: “During Automatic Cycles, drying air temperature and moisture level are sensed continuously in the load. In Automatic cycles, time may adjust either Up or Down depending on load size, material types, and drying rate.”
Note the heading of Maytag’s first check: “Was an automatic cycle selected?” The diagnosis in one question, from a brand with a parts shop attached and no reason to lead with it.
Maytag names the commonest trigger too, and people do it to themselves: “If wet or damp clothes were added after the cycle had started, the dryer will automatically adjust the remaining time based on the new moisture levels found in the dryer.” One forgotten wet towel at minute ten and the cycle is resized around it.
An energy-saving option does it too. Maytag’s long-dry-times page notes EcoBoost “will increase drying times by approximately 40 minutes, which will be reflected on the LED Display.”
Switch to Timed Dry: the test that tells the two apart
Samsung publishes the cleanest version of this check, and it is free. Select Time Dry, hold Start, and watch one number for one minute. Samsung’s wording: “confirm that the timer (for how many minutes until the cycle completes) counts down. For instance, if it starts at 40, then after 1 minute, it should tick down to 39.”
The failing result is the useful half, and Samsung’s reading of it is not what most people expect: “If the timer doesn’t count down after 1-2 minutes, then you have not started the cycle correctly.” A number that will not move on a timed cycle usually means the cycle never began — a door not fully latched, Child Lock on, or Start held too briefly. On many machines Start must be held two to five seconds; a tap is not enough.
So: Timed Dry counts down and the timer is fine. Timed Dry also refuses, and you have a start-permission fault instead.
When the dial really is a mechanical timer
On an older dryer with a rotary dial that rotates during the cycle, a stuck dial can be literal. A small timer motor turns it through a gear train, and three things fail: the knob splits so it spins on the shaft without driving it, the gears strip, or the motor stops. Maytag lists a defective timer motor among the faults it says need servicing. The timer comes as one assembly — motor, gear train and contacts together — which is why a split knob is the only half of it worth checking yourself.
Pull the knob off first and turn the shaft by hand. Pointer tracks the shaft, the fault is behind the panel. Shaft turns and the pointer does not, you have a split knob — the cheapest part here.
One cause nobody else on this search mentions: a dryer that is not level. Maytag notes that if the dryer is not level, “clothes may not come into contact with the moisture sensors during Automatic cycles.” A tilted cabinet keeps the load off the sensor bars, so the dryer never reads it as dry and the estimate stops advancing. A spirit level and a wrench, not a timer.
FAQ
Why does my dryer keep adding time instead of counting down?
Because on an automatic cycle the number is an estimate, and Maytag states that in automatic cycles “time may adjust either Up or Down depending on load size, material types, and drying rate.” A recalculation, not a malfunction.
How do I know if my dryer timer is broken?
Run a Timed Dry cycle and watch for one minute. A timed cycle must count down. If it does, the timer works and what you saw was sensor behaviour. If it does not, the cycle probably never started.
Can dirty moisture sensors cause this?
Yes, on sensor cycles. The sensor bars sit in or beside the lint filter housing and pick up softener film, which makes them misread the laundry. Wipe them with a damp cloth and let them dry.
Will a blocked vent stop the time from advancing?
Indirectly, and often. Restricted airflow means the load genuinely dries slower, so the estimate extends to match. If the figure has crept up over months, start at dryer taking too long to dry.
Is it worth replacing a dryer timer?
Only after the Timed Dry test has implicated it. A timer is one of the costlier small parts in a dryer, and it gets bought to solve a sensor estimate or a cycle that never started.
The estimate is a guess the dryer keeps revising
Ask which cycle is running before anything else. On automatic or sensor, the number is a prediction with permission to stall and to rise, and Maytag publishes a page saying so. On Timed Dry it is a clock and it must move.
That test costs one minute and decides whether you have a fault or a feature. Most people here have a feature, a wetter load than they thought, and a vent due a clean.
