dryer does not shut off
« on: November 01, 2008, 07:40:34 PM »
What can the problem be with a dryer that does not shut off until the door is opened. Can it be something else besides a faulty timer?

Model Number: LER7620LG0 icon

I also removed the back of the dryer and the lint chute assembly.
Cleaned all the lint out of the chute assembly (little found).
Checked the access control panel and beside the timer I checked everything
for  corrosion. Found no corrosion and still have same problem of timer not advancing. >:(

If the timer does not advance to off on the automatic cycle and the timed cycle then you have a bad timer.

If the timer advances to off on the timed cycle, but not on the automatic cycle you have a air flow problem or a bad thermostat.
Hope you find our site helpful.

If the dryer timer will shut down in the no heat cycle you probably need to change the control thermistat. I believe as the dryer needs heat the timer motor is defeated and as it does not then the timer moves closer to the end and finally shuts down. Reg knows more about it than I do.

Installed new timer and put it back together.
Now I have no power. Light on inside does not work. Nothing does.
Yes, I plugged it back in and make sure circuit breaker was not tripped.
Any suggestions now. :tickedoff:

Ah HA! I figured it was the control thermostat. Let me ask you this: Did you clean out the dryer throughly? Including removing the filter blower housing and cleaning that? You probably have a blown fuse.

I have the exact same dryer as you do. The dryer belonged to my son. It came in the trailer he bought and it never worked worth a damn. What the dryer was doing was blowing the upper heater fuse. I could not imagine what in the world was going on because I took the dryer apart and throughly cleaned every last inch of it. I was not until I removed the pipe between the inside and outside of the garage that I finally figgered it out. It had a halo of lint built up in it! I ran the flex pipe out the hole in the wall and replaced the upper and lower heating element thermostat and the control thermostat. That dryer has work beautiful on all the cycles ever since. Like I said before the heater thermostat will feed the power to the motor on the timer when the heating element is not on. So if the clothes are soaking wet then the heating element stays on for a long time. If this dryer is not vented properly then that is only ONE of the things that make this dryer go haywire. So check the fuse and if the timer does not timeout you need to change the control thermostat.

Yep The heater element has 2 thermostats that come in a kit.
The bottom thermostat has a small orange wire that connects back to the timer and powers the timer motor when the element ain't on. And the control thermostat is staying on way too long. At least that was the case with my dryer.

A bad Thermostat won't prevent the Light to work
Check / tighten the Nuts on the Terminal Strip behind the Dryer.

Check the Voltage between the outer Terminals (240v AC)
and between each of the outer Terminals to the center Terminal (120v AC)
