Depending on model, (mechanical timer or electronic timer)

Mechanical dryer timer has a tiny motor to advance it
many times service techs forget to plug in the timer drive motor when they replace the timer switch that it is screwed to
or they replace the switch when the switch is ok, but the motor is bad
Not a solution just something to check
the timer drive motor is a 2inch diameter press formed sheet metal device 1/2 inch thick on the rear of the timer switch
if there are wires hanging off, that is the solution
if there is no hum from the timer motor when you push the start button, replace the timer drive motor

electronic, not had one break yet

Maytag gas dryer lsg 7800 just replaced gas valve dryer now heats but timer does not advance or shut off


Ok that machine was built back in 89, good chance the timer is out. If you really like that machine I would get as many replacement parts I could find for it. They are better machines than the ones they are selling on today's market.

Not catching lint or drying clothes


Hi Diane

Sounds like you have a clogged vent
If your dryer seems to run forever, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.
Normally, this is what happens during an automatic cycle:
The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.
When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)
The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.
This cycle continues until the clothes are dry. But...if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.
Heating Element
Your dryer's heating element may be partially burned out. If it is, your dryer still heats, but at such a low temperature that it takes three or four times as long to dry the clothes. If the element is partially burned out, replace the heating element. You can check for an ohm reading but will need to refer to the service manual for proper reading. This sometimes on the tech sheet located somewhere on the dryer. Usually between 9-13 ohms.
Cycling thermostat
Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork . This thermostat usually has four wires going to it. Check the 2 terminals that are opposite each other and are the closer together of the 2. These 2 terminals should have continuity. If not replace the thermostat.

Dryer wont stop buzzing


follow this steps and fix it. God bless you

Timer
The timer could be the problem. To check this, turn the timer to a timed cycle say 30 minutes or so then time it. If in 30 minutes the timer hasn't moved and the dryer is still on, the timer is bad and need replaced. If in 30 minutes the dryer is off, the heating element is your problem

Heating Element
This is the most likely cause for some dryers timer not advancing. Some dryers have two heating elements and if one goes out the timer will not advance if you use it on an automatic cycle but you will still feel heat inside the tub. replace the heating elements

Comercial maytag dryer will not shut off. tried replacing timer. heats up but will not shut offf


Hello,

When a dryer heats but the timer does not advance especially on the auto. dry setting (not timed dry) the problem is usually always a airflow problem. What needs to be checked is for lint build up in the blower housing, a blocked or restricted. Also on Maytag dryers a problem sometimes is that the blower wheel drive hub where it connects to the motor is stripped so the blower wheel cant move air,typically if that is the case a rumbling will be heard when dryer starts and once again when the dryer stops a rumblimng noise will be heard.

I have a Maytag Legacy Electric Dryer Model MED5570tq0. It turns, gets heat, but does not dry the clothes. It would take 2-3 cycles to dry clothes. Any suggestions?

Dryer heats once or twice then stops heating


It's likely one of the coils is opening a break in the coil as the coil heats up. This coil will shrink when cool and be able to run again. The number for the coil kit, which will replace ALL the coils, for your machine is 12001348.

Disconnect power and turn off gas before working on this dryer. Working on gas dryers is not recommended for people who are not professionals.

Service on gas appliances should be undertaken by professionals only due to the danger of gas leakage which can cause fires or death by asphyxiation.

The disassembly procedure is covered beginning on page 3-10 of the manual listed at the link below. Operation and replacement of coils is covered at page 3-32. Replace All coils with Kit Number listed above. Take care not to touch or hit the ignitor or you will be replacing it also. It is VERY brittle.


Reverse process to re-assemble. Good Luck

Dryer heats &revolves but clothes do not dry


  • The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees.

  • When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.)

  • The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again.

This cycle continues until the clothes are dry. But…if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.
