First problem that was 'fixed' after recently moving not using dryer for ~3 months dryer ran hot (checked ventilation, good output, correct voltages between phases and to ground, good ground source) then one day dryer stopped heating. Checked heating element, good 10ohm reading, no blown fuse, continuity on thermostat... started tracing wires back to control board and found a partially melted relay for the heating element control. Replaced control board: dryer operations returned to normal EXCEPT high over temperature regardless of setting. rechecked ventilation, verified no obstructions internally or externally, checked continuity of both thermal fuse locations, no short on heating element to ground and 10ohm across element, verified operation of thermostat with exposure to heat (opened under ~250F), verified response of thermistor under heating (11.5kohm steadily down to 1k over exposure to heat), don't know what piece to try replacing first. Ordered Main Control Board Part #PD00002035 | Mfg #DC92-00160A just two weeks ago from here. Did notice a 300ohm resistance between neutral and black phase when examining board which matches a MOV on the board (old board had same reading). Doubting it is a bad control board but looking for help.
