White Knight 447WV Dryer - Timer doesn't count down

White Knight 447WV Dryer

Previously had no problems with this dryer but the timer appears to have suddenly stopped working.

The dryer:

- starts fine if I choice a time and press start.
- heats up, etc

The timer just does not count down - the dryer just keeps going!!

Given the above, is this as simple as I need to swap the timer? Is there anything I can test/check first?

Thanks in advance

Yep timer is faulty.

Thanks for quick reply

Any means of testing or are the symptoms that clear? Want to be sure I'm ordering the right part D

No way of test but a classic fault. It runs on cogs inside it and some are poss striped.

Wear from day-to-day use or misuse?

Switch replaced (<5 mins) and dryer seems to work again.

Searching by part number and not make/model saved me £15-£20. Found a small independent who was far more competitive than the larger spares websites.

Opened up the 'timer' on the old switch. It runs on cams not cogs. They have single small cut out rather than multiple teeth. Cams fine - no wear. The timer contains relay style contacts that I would consider dirty/possibly worn - nothing that could not be rectified with a little TLC.

I'm happy to keep new timer (low cost fix) but will keep the original just in case the need to repair arrives again.

To those that did - thanks for your input.
