Tumble dryer power switch problem

It's a Westinghouse LD505e As from today I have to hold the power switch in all the time otherwise it switches itself off. I used to be able to just press once for on, and again for off. Other than that it works fine.

The power switch is non-latching so there's no visual indication of on/off other than the LEDs and beeper. Here's some pics. Power switch is the brown thing on the right.

Does anyone have an idea of how to diagnose this?

HI Mike, The power switch looks like it would be a latching type, It has High current wires attached i.e. its not small signal type like would be used to trigger relays/ electronics. See if you can get hold of a new one and compare it. If your sure its not that, check the door switch. Best luck, don't kill your self, or burn the house down. Allan

Pulled the switch apart (it turned out to be a latching type) and cleaned it. I guess fluff or something got inside.. I was expecting it to be like the front panel switch in a computer which simply carries a logic signal. It's all working now.

Thanks

Mike
