Hi, I don't know if this is really the right place to post this but hey ho.
I am trying to find out of anyone knows where I could source a fan speed control sensor for a qualitair condensing unit j90743. The current one looks like it has popped, removed it from the copper tube housing on the condenser and it is full of a white paste/powder which looks like the internals of the sensor.

I have had a cost from qualitair but it is more than I want to pay really so was wondering if anyone knows where I could probably get it cheaper?
