Expert:  Techdesk replied 3 years ago.

Hiya,

OK, if there is no signs of life then it's more likely the thermal fuse has failed.

 

There's a removable panel below the door.

Open this up (unplug or isolate the power first).

 

On top of the ducting you'll find a thermal fuse.

Take the wires off of it and test with a multimeter to see if it's open circuit.

 

If it is, you'll need to replace it.

 

When this fails, it stops everything on the machine.

 

Check it out, see what you find and get back to me

 

Hope this helps

Thanks

NO SIGN OF THERMAL FUSE OR DUCTING IN THE AREA MENTIONED. COULD THE PROBLEM BE THE THERMAL SWITCH?WHICH MAKES A CLICKING NOISE WHEN START BUTTON IS ENGAGED.EARLIER I TRIED TO LOCATE A TIMER SWITCH FOR THIS MACHINE WITH NO SUCCESS.

Expert:  Techdesk replied 3 years ago.

Hiya,

No, it's likely the thermal fuse which is normally on the ducting.

 

Do you see the fan?

If yes, go to the right of it and on top of the ducting you should find the thermal fuse and a thermostat.

 

If your machine is really old, the thermal fuse may be on the rear of the machine.

You have to take the panel off to find it.

As you mentioned Philips in your question it would suggest an extremely old machine.

Check the rear for the fuse.

 

Thanks

On the fan housing there are two small items which could be fuses.


One is oblong {white} with two blue wires attached and there is also a round unit with four wires {2 blue and 2 red}with machine switched on all these wires appear to be live. Hope this helps.

Expert:  Techdesk replied 3 years ago.

Hiya,

The one with 2 wires is the thermal fuse.

 

No idea what you mean by they all appear live.

Take the wires off of the fuse.

Test for continuity using a multimeter.

 

If it's open circuit, it's the fuse at fault.

 

Thanks
