Overheated for Model Number LER7646DZ1 Heating element tests good (not open) 11 ohms or so, Replaced the thermal fuse and thermostat 2x, both times fixed the no heat problem. But after the 1st replacement, thermal fuse went out 15 days later, bought another set replaced it and it lasted only part of a cycle. The only thing I can see wrong is the heating element plate ( between front and back coils) is charred black over 3/4 of the plate(from the middle of the 2nd from bottom coil to the top end of the plate). Is that normal??? Voltage at plug is 114 and 116 on ea. side. Thermal fuse replaced with Thermostat Kit 279816 for Whirlpool Kenmore Dryers which has fuse and thermostat. Could it be the coils are getting too hot and catching fire? All lint has been cleared from vents, tubes, fan blades, etc.
Answer Hello Overheated. Check and see if the temperature coming out of the dryer is cycling. It should go from 120°-155° +- 10%. If not, you will need to replace the cycling thermostat WP3387134, if the heater is good and not grounded out. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps.http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
