Maintenance & Restoration

swfla bill · 05-12-2023, 08:26 AM

My 2001 Casita has a Coleman roof mounted a/c unit (6727-736)
The fan doesn't run but compressor kicks on a few seconds after powered up.
I am looking for a replacement start capacitor. The one installed is a
Mallory
21-25MFD 165VAC
1497-021
235-0015-03
This cap has a resistor mounted between the contacts , color coded,
Yellow -Orange-Green-Brown.
Will I need to order that resistor separately?

I'd just reuse that on the new cap if it's not toasted.

Just Google it. It's just that easy.
Do not reuse the resistor as it could be whats bad.
Start with everything new.

OEM is the way to go.

Could be the fan motor is no good.

It certainly could be a bad fan motor, but there is an easy test for this.

Have someone help you inside the trailer. Be ready with the cover of the air conditioner removed. Have your helper turn the air conditioner on. At the same time the helper turns on the air conditioner, spin the fan. If the motor is good and the capacitor is bad the motor should run if you start it by hand.

Be safe. Don't fall off a ladder or get electrocuted.
