Heater Pot Testing

[Griffit]

I think I've finally located the pot on my hot/cold heater valve, which is currently constantly turning anti-clockwise.

Is it possible to test whether the pot is working or not to determine if I need a new pot or whether something else is the problem e.g. broken wire?

How would I go about testing it? Would I need to measure the resistance from the centre leg to the side legs to see if it changes as the motor turns?

Anyone?

Yep you can test it if you have a multimetre. Check the resistance, think it should be something like 0 through to 10k ohms from memory. Somebody like David Beer will know for sure.

Yep is 10k, check the wires to it, most likely one broken off.
