Whirlpool (Estate) GAS Dryer (model #TGDX640EQ0)
My Dry won’t heat up enough to dry the closes. (I replaced both my coils just yesterday).
I’m suspicious of my Dryer high-limit thermostat. The high-limit thermostat is opening and closing alright (I’ve tested the open /close state with my multi-meter) However the high-limit thermostat seems to be cycling the burner off before the dryer has a chance to warm up. Then it seems to take a long time to cycle back to a close state and ignite the burner again. When I pulled the thermostat out away from the dry (I left it hang outside the heat vent) the burner seems to run as long as I’ll let it. Is it possible for a high-limit thermostat to have issues with the open / close temperatures? Is there a way to test the thermostat for its cycling temperatures? OR; is it possible my burner is burning to hot?
ANSWER Dave, you're on the right track, The next step to make, disconnect the exhaust vent from the back of the dryer and recheck for the heat operation. A clogged exhaust vent or lint filter, distrupts the air flow, and causes the hi limit thermostat to open, it should'nt ever open. You may want to replace it, it could be weak (due to cycling off and on) but check the venting and lint filter area for clogs, first. Thanks and Good Luck.
