    That's not it. The problem was the timer switch.

  • Anthony Longo Apr 13, 2011

    I had tested the circuits again last week. It was the BU/BK circuit. I replaced the part last week successfully.

Hi.

Defective thermal fuse and/or thermostat result in no heat (some model does not tumble) and the dryer still turning on. Some other fault like defective drive motor can cause dryer suddenly turning off.
The only fault that can cause the dryer starting on its own is the control assembly or by a wiring problem. In this case it was the timer.

PS: the thermostats and fuse could have been tested using a multimeter set on Ohms. If they are open (Ohms infinity) at room temp., then they are faulty. A bimetal thermostat opening and closing erratically with vibration is something very unusual. If that happens, it would be caused by wiring rather than by the thermostat.

Regards.

Hi

The issue can either be with the door switch or the timer, you will have to test both of them before replacing the part. Hope this helps...please post back for further assistance.

Check the door switch as this switch is a 2 part switch 1 side for the drum light when the door is open and the other side is for the dryer circuitry when the door is closed,they do wear out ,there should be 3 terminals on this switch and 1 is common to the other 2 connections

Lg dryer is overheating blowing the thermal fuse


you have an airflow problem. Check the vent hose all the way out and the outdoor vent hood.
a simple verification can be performed by disconnecting the vent hose from the dryer and see if this solves the problem.

I have a Kenmore Series 70 Dryer and I changed the thermal fuse got hot for a few minutes the model #110.74722400


The cycling thermostat must also be replaced when replacing the thermal fuse. The cycling thermostat's failure to cycle off the heating element results in overheating of the dryer which consequently blows the thermal fuse open.

Replacing only the thermal fuse should the dryer stops running and fails to start will result in its premature blowing or even the thermal cut-out (cut-off) located on the heater duct. Like the cycling thermostat, the high-limit thermostat must also be replaced once the thermal cut-out blows open. Refer to the parts diagram in the link below and look for item numbers 31(thermal cut-off), 34(hi-limit thermostat), 39(thermal fuse), and 41(cycling thermostat.

1 week ago the dry was extremely hot and now this week the dryer is cold and the clothes are wet.


Last week your cycling thermostat went bad. This week you thermal fuse went out. This is how it happened.
You dryer cycles on a thermostat. When it goes out the dryer then cycles on the (high limit) thermal fuse. When it goes out. The dryer stops heating. You will find both after you remove the back of the dryer. They are easy to replace. There are two different thermal fuses but if you order the parts using the model number you will have no problem. These two parts are sold in a kit.

The Dryer stopped and will not start again


Just had a similar problem with our Maytag Electric Dryer. The dryer shut off mid-cycle and wouldn't start again, but the timer kept running. We purchased a "Thermal fuse replacement kit" at a local appliance parts store for $38 and replaced the fuse ourselves. The dryer is running great! Here's a couple of website links that were helpful in figuring out out how to replace the fuse: http://www.partselect.com/repair.aspx?appliance=dryer&part=replace-thermal-fuse

Hope this helps!

Whirpool dryer stopped working


Check the following to combat this issue.


1. No power to the dryer
Make sure there's power getting to the dryer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power with a voltmeter or by plugging something else in.

2. Door switch / Door switch actuator lever
The dryer would not start with a broken door switch. Replace the door switch if found defective.

Most dryers have a door switch actuator lever - when you close a dryer door, it presses against the lever, which actuates the door switch. If the lever is broken, the switch would not activate and the dryer would not start. Replace the lever, if broken.

Note: Door switch actuator lever usually comes with the door switch assembly and it is recommended to get the whole assembly since there is almost no price difference between the door switch assembly and just the lever. Check your model for more details.

3. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

4. Timer
Replace if defective (note: uncommon problem).

Kenmore dryer model 64602 wont turn on???


Check the thermal fuse on the rear of the dryer.
Remove the rear panel. The thermal fuse is 1 and 1/2 inches long by 1/2 inch wide. White in color and located just left of the dryer exhaust vent. 2 purple wires. Jump the wires together and start the dryer. If it runs, replace the thermal fuse.

Dryer runs but will not heat. Replaced fuse and


your cycling thermostat needs changed too. the thermal fuse is your last safety measure that goes, which means your cycling thermostat is not shutting down the heat element once it detects the right temp hot air in the blower housing so it let the heat element glow until either the high-limit sensor shuts the heat down or the thermal fuse blows. Change the cycling thermostat and good luck

Dryer doesnt work but i hear the timer working


Change your cycling thermostat. When your cycling thermostat fails, then the reponsibility of your heating element to shut down goes to the high-limit thermal shut off (closest to heat element) and the thermal fuse. Your cycling thermostat should shut down heat element when it detects about 140* air in the blower housing. Yours can't detect that anymore so it lets your dryer heat up and up till you blow the thermal. new cycling thermostat and thermal

either you are pushing the dryer back to far and crushing the exhaust vent hose .your exhaust vent going outside is stopped up , or your low temp thermo will not let the dryer cycle and it is over heating.
