My White Knight Condensing Tumble Dryer (WK767c) occasionally delivers no heat. Resetting the ‘Red Button’ (Inlet Themostat trip) always resolves the issue (for 2 or 3 more drying loads) before it trips again.
The Dryer has worked faultlessly for several years in the same position. The warm air ducting channels are clear. The Condenser Fins are clear. Could the Inlet Thermostat be failing?
If so, is Part No. 421309221261 the spare I need?
