rooftop unit hums fan does not engage
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?

Which a/c unit and if possible model number do you have?
I did find this link, but it requires more data.

Thanks for good pictures. Here's that fan cap, from Amazon.
No (not even Coleman RV) offers a cylinder-shaped replacement for that fan capacitor. You'll be buying one which is more like a tall oval.
Here's the OEM replacement, more costly: https://www.amazon.com/Fan-Capacitor.../dp/B004RCR3AM
This one is the same thing in all ways, for less than 1/3 the price: http://https://www.amazon.com/7-5-MF...dp/B09K839HK1/

Thank You for the help
Thank You for the help
I found the exact one, yes more expensive but I'll deal with it.
Couldn't have found it without your help.

What kind of meter did you have? A conventional VOM or DVM uses DC for testing. A good capacitor should show no current with DC. If it shows DC current, it is leaky, and therefore bad.
A lab-grade capacitor tester will use AC for measuring the capacitance value, but will use DC for a leakage measurement.
