Estate Dryer by Whirlpool takes too long to dry
« on: January 25, 2009, 08:04:36 PM »
The dryer takes about 2-3 cycles before drying.  The vent is clear & seems to be blowing strong.  How can I tell if the problem is the hi limit thermostat or (low) operating thermostat?  Also how do I test the thermostat heater?  The link to the wiring diagram is:

Thanks everyone.

You test the thermostat heater with an OHm meter, like everything else. If it shows continuity thru the small terminals, great. Thermostat issues are not the usual cause for long dry times.

The better way to test it is to clip your meter leads onto the large terminals, place your thermometer in the duct, and watch as the unit cycles thru to the operating temperature of the thermostat to see if it opens properly. The  thermostat heater only comes into play for  lower temperature settings and  will not affect Regular dry, so if the stat will not open on its own the heater is useless.

Be sure and conduct any dryer testing with the vent disconnected and the drum empty.

I don't think that's your model number,
maybe more like 110.72202101 ?

(Whirlpool) Kenmore Gas Dryer.

It could be a bad Gas Valve Coil.
They work when cold, but get intermittent when hot.
After the Flame goes out, the Ignitor keeps trying to re-light,
but no Gas.

Hi all again. The model # is correct & it is electric. The model # is stated right on the door.

Anyway, I finally found time to move the washer out of the way & pull out the dryer to tear it apart. I found a ton (~1/2 of lint on the floor, all over the back & inside the back panel.) Even though the repair man said it was blowing well no way was it. I remove the lint screen & then the lint housing that goes to the blower motor & found that the lint housing was almost full of lint & debris, like ear rings, paper clips & other junk. It was a real fire hazard inside but nothing happen as of yet.

Anyway, the blower motor blew the thin foam seal between the lint housing & the blower hosing because it was full. Is there a specific foam seal I should use or are they all kind of standard?  Hopefully any dryer manufactures seal will work. Ill have to look around.

Also, where does the dryer get its air intake from? I understand the path from the heating element, through the dryer drum, through the lint screen, then down the lint shoot, though the blower & out the vent. I guessing from the venting on the back cover & any other place air can flow into the dryer?

Thank for the help everyone.  
