What was the reason to replace the capacitor?

heat pump capacitor


Hello:

It is getting very hot down here in Florida. Your assistance in the matter of my capaicitor problem would be very much appreciated. The wiring diagram in the unit doesn't match the color of the leads going to the capacitor. The capacitor has three terminals(Fan, HRR and blank). I have an orange to the blank, a brown to the the fan and a darker brown to HRR. Do the brown leads need to be reversed?

The air coming out of the vents was hot. The air handler was working fine, but the compressor outside had a non-functioning fan. Took out the fan and had it tested(rated OK). The capacitor was rated as non-functioning during its test.

If you replaced the dual capacitor, and the fan is running slow. I guess, the motor bearing is bad. You have to replace it.

Also, you need make sure the condenser coil is clean.

F - goes to the Fan
H (HRR) - goes to the Compressor
C (black) - goes to the contactor

The motor was tested yesterday at a motor shop. It ran full out. Could I have reversed two of the three connectors on the capacitor to have caused this problem?

Coils are clean and unit ran fine before fan stopped running the other day.

Reading your other post, it seems you reverted both wires. Since the wires are brown and dark brown.... just connect the brown wire coming from the fan to F on the capacitor, and the another brown is coming from the compressor on H on the capacitor.

Thanks for merging the comments.

My leads are orange, brown and light brown. The colors on the units wiring diagram are different, that why I am confused. Also, my markings on the wires came loose before I had a chance to replace the capacitor. Thats why I am confused. I am afraid that if I don't get the wires right, I might damage the compressor.

Like I said, You need to trace the wires. you have 3 wires right? they are coming from compressor, fan and contactor......

The wire is coming from FAn you have to connect at F on the capacitor
The wire is coming from compressor you have to connect at H on the capacitor
the another wire goes to C on the capacitor.
