How do I check my AC compressor windings?
How do I check my AC compressor windings?
Here is how to check the compressor motor if you suspect it has failed;
- Disconnect power.
- Remove the top of the outdoor condensing unit.
- Unplug the 3-prong plug on the compressor.
- Set your multimeter to ohms.
- Measure and record the resistance (ohms) measurement of each winding.
What causes an AC compressor to not engage?
If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.
What’s the low side psi of an AC compressor?
Low side PSI at say 75 degrees would be around 35 PSI. Believe your switch has failed. It unscrews and another screws in, a shrader valve stops loss of refrig coolant. Wear protective PPE ‘anyway for your eyes. High side PSI of around 180 PSI. Some running down the highway might read 220 PSI.
Why is the clutch not engaged on my gas compressor?
But if the system is low on refrigerant, the clutch will never engage. Some DIYers then hotwire the low pressure switch to force the compressor clutch to engage while they recharge. BAD MOVE. At that point you’re running the compressor with little to no oil.
Is there a fuse for the AC compressor?
Went to heater control panel, have 12 V at ac switch, (with blower on) and so switch is sending it down the line but where it goes to, I don’t know. Can’t find any fuse or breaker labelled AC. Tried running a separate set of wires directly to ac comp, it kicks in fine, draws 3.2 amps.
Is there no power to an A / C compressor?
No power to a/c compressor, I have checked the fuses, relays and freon. Clicking this will make more experts see the question and we will remind you when it gets answered. You can’t post conmments that contain an email address.

How does an AC compressor clutch receive power?
AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches. Or, the relay can be operated by the PCM which has interpreted the condition of the low and high pressure sensors.
