Dryer worked fine until about 2 years ago at which time it stopped heating, solved problem temporarily by replacing hi temp thermostat, dryer fails every 2 to 3 months, either no heat or excessive heat, have replaced both thermostats on heater box several times, solves problem for awhile but does not last, recently after a high heat problem I replaced thermostats again though they tested fine, as does heating element and cycling switch / thermostat....still too hot at normal settings, I did discover this time that if I touch one terminal of a thermostat to the back cover (which I cut access openings in) I get a reading of 120V.....found accidentally by touching while tightening clamp om vent tube. What gives? am becoming very frustrated, please any advise would be appreciated.:( dnm1971@yahoo.com.

model number is 110-67622600, dryer gets too hot on normal settings, must be set on delicate to dry normal loads, cycles normally but gets hot [emits odor, hot heating element].

The heating element is not grounded. I just checked it again, and removed it, physically looked for any visible irregularities, none observed re-installed and installed yet another new set of thermostats and checked all connections, all seems well.....it still runs hot.
