I have a limited knowledge of electrical circuits and recently it got put to test. I live in Arizona and the A/C on my house quit. I found that the condensing fan motor had siezed
This is what was in the unit. 1/5 hp, 825 RPM 208-230 vac, 1.1 amp with a 7.5 ufd capacitor. The local wholesaler only had 1/4 hp motors, so I ended up with a 1/4 hp 825 RPM 208-230 vac, 2.2 amp. They gave me the same capacitor.
The new motor ran for a while and started tripping on the internal thermal protection. I called the supplier and was told that this motor should have a 5 ufd capacitor.
I changed to the 5 and the motor would run longer, but was still tripping. I took this motor back to supplier and brought home a new one. I noticed on the box that the capacitor for this motor should be a 5 MFD 370 VAC.
My question now is, is MFD milifarad or microfarad?
Could going from a 1/5 hp motor to a 1/4 hp motor change the capacitor requirement by that much?
If anyone can help, I should would appreciate it.
Thanks
Paul
