How to troubleshoot no power to my Carrier AirV 68RV0010BA Air Conditioner?
- N
  Natasha BrownAug 8, 2025
  If your Carrier Air Conditioner has no power, there are several potential causes. First, ensure the master switch is on; if it's off, reset it. Check the circuit breaker and reset it if it's open. Defective wiring, loose electrical connections, or faulty components like switches, the thermostat, or the fan can also be responsible; replace or tighten these as necessary. For ducted systems, ensure the 12 VDC is connected to the power source and that the in-line fuse is not open; connect or replace these if needed.

What to do if the compressor power supply is open on my Carrier AirV 68RV0010BA?
- P
  Paul BurnsAug 17, 2025
  If the compressor power supply is open in your Carrier Air Conditioner, check for loose leads at the compressor terminals and tighten them. If that's not the issue, the motor overload switch or the capacitor might be defective and need replacement. Open compressor windings or a seized compressor will also require replacement of the compressor. Lastly, verify the capacitor wiring according to the wiring diagram to ensure it's correctly wired.

Why does the compressor overload cycle on my Carrier AirV 68RV0010BA Air Conditioner?
- S
  Steven RodriguezAug 27, 2025
  If your Carrier Air Conditioner compressor cycles on overload, it could be due to a defective run capacitor, which would need replacement. Other potential causes include defective compressor bearings or valves, a greatly restricted evaporator air flow (possibly due to an iced evaporator coil), a low refrigerant charge, or a restricted liquid line or evaporator capillary, all of which may require replacing the unit. A hot compressor may indicate a need to verify the refrigerant charge, check the AMP draw and delta T. Weak or inconsistent line power can also cause this issue, so check the line voltage at compressor start-up.
