Friends Whirlpool Thin Twin came with purchase of condo half a year ago. A month ago it stopped heating. I checked continuity and found the Thermal cut-off switch was open. Purchased Dryer thermal cut-off kit
and replaced as per instructions. Heat has returned and dryer works as designed.
A month goes by and dryer has no heat again. Check parts from the following diagram: AppliancePartsPros.com LTE6234DQ2
Part number: AP3094244
Dryer thermal cut-off: open (again)
Part number: AP2973862
Dryer high-limit thermostat: closed
Part number: AP2946932
Cutoff - tml: closed
Part number: AP3131939
Dryer cycling thermostat: closed
Part number: AP3134638
Heating element: closed, reads ~12 ohms
Checked both leads of coil to frame, all open
Before I go and replace this same part again, what else should I check? What other steps are necessary to diagnose the original cause of this failure?
Checked vent hose: clear of debris
