After the first load the dryer runs very hot. I cleaned out all lint, replaced the vent to the outside, tested the thermister and th ethermostate at teh top of the heating pipe. A parts store checked the ohm reading on these and compared them to new ones, they read the same. Is this is good test? I tested the thermostat at the bottom of the heating pipe or tube. I warmed it in a sjillet and verified it opens and closes. I also checked the heating coli. tested ohms on both legs, there was a reaading. then i tested each leg to the tube and had no reading. Visually inspected to see if anything got in there. Any suggestions for next steps. I am trying to take care of this and avoid costly repair visit or new purcahse. ANy help is much appreciated.
