b.Failed DMC computer temperature sensor.

J.DMC computer L.E.D. display reads “Hot”...

The “Hot” display condition indicates a possible overheating condition. The DMC computer monitors the temperature in the dryer at ALL times. If the DMC computer detects that the temperature in the dryer has exceeded 170º F (77º C), it will disable ALL of the dryer outputs (shut the dryer down), the buzzer (tone) will sound for approximately 5-seconds, and the L.E.D. display will read “Hot.” The L.E.D. display will continue to read “Hot” until the temperature has dropped to 170º F (77º C) or lower and the DMC computer is manually reset by closing and opening the Program Switch (PS).
