It is the ‘Reversing Timer’ and cuts supply to the heater for a few seconds whilst reversing. They often fail (Part No 1701133) available by emailing the details to spares@ukwhitegoods.co.uk

Thanks for the info. Before I go ahead and replace this timer unit, can you tell me what the black box next to it is. This black plastic part is not part of the timer block, and looks (very difficult to see) like the micro switch used on the door. Could it be an air flow sensor or weight sensor?

We only have line diagrams to work with Scott so I don’t quite know which part you mean, I think though you refer to the float chamber. There is no air flow or weight sensor in the dryer 😉

Hi Dave

I am not sure if this will make it any easier to establish what this part is, but it does seem to have a thin length of metal which sits in a V shape piece of plastic. When I raised this metal arm I could hear a switch contact noise.

If the fault is actually the timer rev what is the best way to prove it is at fault?

Yep, that’s the float chamber by the sound of it.

Continuity test as I mentioned previously to check 😉

Dave.

Cheers.

Is there a datasheet for this reverse timer available, so I can determine whether is functionally sound?

I’m afraid not, even we aren’t privvy to such material without being charged through the nose for it 🙁

That doesn’t surprise me. I plan to carry out the continuity this evening, please advise which pins on the timer unit should be connected together or not as the case may be.

Thanks for the advice. As it turned out it was the thermal switch by the door which was faulty. Out of circuit is measured as closed but the mere sniff of warm air caused it to open. I could get it to open with the heat from my finger.
