LG dryer (DLE2150) sucked in sock and turn off

Hello All,

This was 100% my fault. I started a cycle without a lint filter. Very quickly it made a noise and turned off. I realized what happened right away. The machine shut off and power button wasn't doing anything.

I took the machine apart and pulled out the sock from intake on the motor. For this I followed the attached manual. I put everything together but pressing the power button doesn't do anything now. I am guessing some safety was tripped. Is there some fuse I need to change? Is there something else I need to rest?

Any ideas?

Thank you

Welcome to the forums.

You need to check the first item on the list .......thermal cut-off to see if it's open.
Basically all thermal switches should measure as 0 ohms..... shorted.

If you had the front off..... check the door switch wiring.
Page 36 - tub drum/front step 3.

Thank for the reply. No luck. I measured 2 fuses I found on the heating element. Both reading 0.05 omhs. Looks like like they are fine.

Sorry, I don't follow why I need to check front door wiring. The light comes on when I open the door so there is power coming in but nothing happens when I try to turn on (not start just turn on).

There are usually three wires on that plug.
One is power. One is the light and the other is power to the dryer.
The dryer won't start if it thinks the door is open.

What do I check on the connection? Resistance on some wire? It didn't turn on at all after it stopped. Even the LCD screen. I assume there would be some error code on screen. So, has to do something with sock that was stuck to motor.

I think I might need a new controller. I am not sure what the yellow connector on controller is but it appears there is some damage and I can smell burning scent when close to it.

You need all the plugs in place. Then you need to 9/diagnostic test.
If the display doesn't power up then you need to go down to test 1 for electric.

I don't know why the yellow plug shows a burned spot.
It looks like it just monitors the heating elements.

Were there any wires connected to the yellow plug? If there were where do they go? Been to many years since I have been in one to remember what went where. I can't think of anythin dropping a sock into blower would do. Have taken many out with no damage to dryer.

Check the thermostat or whatever they call it on the blower. It is the one tat kills power to the motor.

The ones on the heater just kill power to the heater.

The problem is that it isn't just a dead motor. It's a dead display. There is a switch? (red circle) that supplies the transformer with neutral. It's not labeled. I have no idea what that is. Maybe a push-to-start to wake the board up ?

On edit: I have an idea.... that item in red is a relay and gets its neutral from the switched neutral from the door switch and applied to pin 1 of WH4 (white) connector. That would mean an issue with the door switch which is highly likely.

The single wire in the yellow plug looks to monitor the safety stats. If they are open that wire gets no power. Probably for the diagnostics. It doesn't like any major power is drawn thru that wire so that I can't see why there is a burn there.


The yellow (neutral) and blue (hot) wires are just for reference.
Those wires feed the door switch and the light is working normally.

Took me some time. A lot of this is over my head.
- I tested the door switch with volt meter. COM -> NO -> NC and it seems to operate as expected.
- Disconnected everything except light + door switch. The switch correctly operates the light when plugged in.
- connected everything back and display doesn't come on when door switch is pressed

Will dig a bit more tomorrow. Too bad but it looks like this model controller board is no longer sold.

The control board is part # EBR36858801

I see it available at several online parts retailers. Search using that part number.
If you decide to get the board you'll need to see who ships to Canada.
