Hi

Can anyone shed some light on how to test heater resistor?

Is it just continuity?

Thanks

Thanks

I went over everything again check heater fan all ok there.
Checked fuse and it had blown possibly because of previous seized fan.

Replaced fuse all working

Thanks again

Heater resistor is a set of very low value resistors connected in series. They are wire wound resistors, so very unlikely to change value - they will either be correct or open circuit, so, as far as the average multimeter is concerned, just measure for continuity.
Note that there is a self resetting thermal cut out built into the resistor pack, and it's this part that gives the most trouble.
