Just one last diversion if I may....

Critical as in - everyone knows the world stops unless lubricated with sufficient cups of tea? Or critical as in, you were actually blending/refining teas?
Curious minds....
Andrew: Presumably, the low end of the resistor was providing the maximum temperature (i.e. tending to zero ohms). With your old pot failing "high resistance", it could no longer tell the machine to go to maximum temperature. Normally if a pot fails at high resistance the issue is with the wiper; often the wiper & "output leg" are wired together, which I assume was the case in, er, this case.
So... that given... it wouldn't matter if it was a 28k pot, a 50k pot or even a 147k pot... the low resistance end would give the maximum temperature.
However... I'm sure you've thought of all that stuff (cos I knows you are good with electrickery), so if I'm talking out of my Chinese hat, just say so...

Ade, the original pot wiper had been knocked off in the dis-assembling of the original device - my own clumsiness not removing the shaft before laying it on the bench. The actual track was undamaged :scratch:
Any road up it's working and making me tea and coffee, and the fixed 'spares or repairs' one tucked away for the next failure :lol:

Hi there, all,
Sorry if this is :offtopic: :offtopic: :offtopic:
But please can someone tell me how you get two (or more) quotes in the same reply?
mattinker:
Cut and paste the quote from another reply!
