Question and Answers


Dryer Pro blem LER4634PQ1 Whirlpool Residential dryer


Thank you for a good description of the problem. The first thing you want to do is reset the double 30 amp breaker incase it has tripped. The dryer will run on 120volts but takes 220volts to bring on the heating element.

If the breaker is ok & the unit is receiving proper voltage you will need a meter to check a few critical components.

Before making any tests I recommend checking to see if the control has an error code that will lead us to the problem; it sounds like the thermister, control board or a wiring harness connection.

I am sending you the test mode set up instructions & error code list from the service manual in the attachment below. This will guide you through the process step by step.

I am also sending you access instructions.

First disconnect power 

to the dryer. Remove the 2 screws holding the rear panel in place; slide back & lift the panel off. You will see the control & wiring. Look closely at the red wire going to the control board heater relay for connection problems.

Disconnect the thermister harness J2 and use your ohmmeter to check across pins 4 to 5; you should read approx 50K ohms.

Another possibility is the hi-limit thermostat or the heating element. The hi-limit located on the heater housing should test closed, 0 resistance. The element should test 12.8 ohms.

After making the checks & tests please report back to us your findings if you still need further assistance, thank you.

The bigger problem would be the dryer running for 10 minutes then stopping. If the motor doesn't run then the dryer will not heat. I don't suspect the thermal fuse is the problem because once the fuses opens the motor will not run at all. When the motor runs 10 minutes and shuts off I suspect a low voltage problem or a motor switch/motor problem. If a meter is available then you can check voltage at the outlet while the motor is running. One thing to try is to run the dryer with no heat option selected. Check if the dryer motor will run longer in an Air Fluff/No Heat Cycle. You can reply with any additional details for further assistance.
