Problem with rooftop a/c, heat & fan unit. 2007 TM 3124 KS
This appears to be the original RVP 9000 series.
It worked fine about a week ago. Now it just hums in all modes, including “fan”.
We checked the capacitors with a meter. Two had current through them. The third, GRAY one, did not.
Does anyone know the replacement part for the GRAY one?
