No Heat on a Kenmore Electric Dryer 11085862400
Ok, so I have been looking and looking for the problem to this dryer. I have had it apart numerous times. I have metered out the heating element, thermal cut-off fuse, thermostat, non-resettable thermal fuse and replaced the thermistor (1st thing I did) and still no heat. I check the voltage to the dryer as well. I even took all of the parts in to a local parts store and had them check the parts as well. What would be next on the list? Help the wife is on me to hire a guy!

You should have a wiring diagram. On control board toward the back is the heater relay. With dryer running and in heat should show 0 volts across the 2 terminals. If shows 240 you have a bad relay and need a control board. Be very care full 240 volts in there. Did you put it in diagnostics and did it come up with a code?

Thanks for the feedback. I will find a wiring diagram and test the relay. So what your saying is turn the dryer on in a heat mode and put the meter on it. I did not put it in diagnostics. How do I do that?

Tech sheet should be in bottom of dryer and will tell you how to do it and wiring diagram will be in also. Usually in panel you take off or taped to side.

Ok. so I got in there and the tested a part manufactured by Potter & Brumfield. It stated it was a 240V part right on it. Started dryer in normal mode and put the meter on it it read 248. Based on what you said it should have read 0.

Sorry I missed your reply. One other thing to look at is to see if the heater circuit goes through motor switch. If that switch is open will also give you that reading . Yes should read 0 when running. To check motor switch (unplug dryer first Look on wiring diagram and see what color wire comes off motor, at heater unplug that wire and than check voltage there, should get 120 there.

If your reading 248 volts across the relay terminals, the motor switch is good. You would not read anything across the relay terminals if motor switch is open regardless if relay is open or closed. You have a bad control board.
