Kenmore dryer heater turns on unless unplugged
« on: February 23, 2013, 12:34:30 PM »
I replaced the thermal fuse in my Kenmore electric dryer last week (went bad). It burned out again yesterday so I threw a new one in today. Just noticed that as soon as I plug in the dryer, the heating element starts up without the dryer being started. The thermal fuse must be a symptom and not the problem.

What would cause the heater to start without the dryer being turned on? Clothes are now searing hot. Not a problem with the vent. Obviously it's unplugged right now.

Heating element shorted to ground, thats what overheated causing thermal fuse to go.

Do you have a model number?

Looks like model 110 62812100 according to the tag. Do you think if the heating element went bad it would start heating as soon as I plug it in?

The heating element was so hot it cracked the alum mounting plate, but it still has continuity. Obviously it needs replaced. Could the thermostat have caused this?

Check continuity between either terminals and the heater CASING.  Let us know. O0 :D

Replace it, or you will be buying a lot of thermal fuses.

From the looks of that element, I'd say you also have restricted venting. Make sure the dryer is not pushed against the wall and crushing the vent.  If you have a long vent run, brush it out. The Linteater, RLE202, works great for this.

NEVER hurts to check the vent, but I believe that sagging is going to be caused by the heater being energized when not actually running.... No air flow. :D
