Old Kenmore Elite 90, Model 110.60954990.
The heating element will turn on, but will not stay on for more than 30 seconds. It will sometimes kick back on after a few minutes, but again for no longer than 30 seconds.
This happens with both Timed Dry and the Even Heat.
Took the whole thing apart. Cleaned out all vents, was not all that dirty.
Replaced all common failure parts anyway (See below)
Tested all the elements with multi-meter. All seemed fine.
Voltage to unit at 240 checks out
Timer: checks out
Thermistor on blower assembly: okay upon testing, replaced anyway
Thermal cutoff: okay upon testing, replaced anyway
Hi-limit thermostat: okay upon testing, replaced anyway
Heating element: checked, is okay
Motor switch: checked just in case, is okay
Ran it without vent attached to ensure no blockage and plenty of ventilation.
I'm at a loss here. Only thing left would be one or some of the elements on the console panel.
Those are a bit more expensive just to hope a replacement would work.
What is telling the components to shut off the heating element after only being on and glowing for 20-30 seconds?
