LG DLEC855R tE3 error
I'm helping a friend out who is having issues with her LG electric dryer. The dryer will run for about 3 minutes, (it will not heat), and then shut off with a tE3 error code. I've been told this error is a thermistor error so I connected my multi meter up the the thermistor connector and got 11 ohms at room temperature. I read somewhere that the thermistors rarely malfunction and if you have about 11 ohms of resistance it is good and more than likely the circuit board is bad. I replaced the circuit board but am still getting the tE3 error.
While I was checking the unit out I did find a sock wedged under the lint screen, it looked like it had been there for a while, so I'm assuming this caused the dryer to overload somewhere but not sure where else to turn to.

Not sure if this helps, found this...a copy:
'TE1' error code - Heating Error - Low temperature thermistor open circuit
'TE2' error code - Heating Error - Low temperature thermistor short circuit
'TE3' error code - Heating Error - High temperature thermistor open circuit
'TE4' error code - Heating Error - High temperature thermistor short circuit

Thanks for the quick reply. You don't happen to have a link for a service manual or a schematic where the high thermistor is located do you? I tried a search and couldn't find one.

That won't come up for me. I got DLEC855W to work for me.
D210 is a thermostat
B135 says thermistor

Thanks for the diagram Jeff. The W and R at the end just means white or red. It must be the thermostat that's bad because the thermistor checks out OK. I'll check it out.

Let us know what you find/see....thermistors can be intermittant as well!

Don't be surprised if replacing the thermistor doesn't solve the problem. I had a brand new LG dryer unit give me a te1 and te3 intermittently. Found it to be a bad wire harness. Replaced the harness and everything was good to go.

Got it fixed.
It was the high thermostat, the one in the back, fortunately it was a thermostat with a reset switch so I just had to push the switch and the dryer was up and running again.
Thanks for all the help, it is greatly appreciated!
