advisory

This is not usually an immediate safety hazard, but do not keep resetting it. Try only the safe homeowner check below; if the same code returns, schedule service.

Likely causes

  1. Brief power event, brownout, or unstable supply voltage
  2. Loose power connection, reactor, or outdoor electrical component problem
  3. Inverter/IPM protection or current-detection fault
  4. Compressor winding, drive, or outdoor board fault after power checks pass

Homeowner fix

Turn the system off and reset once if safe. If C463 returns, leave the system off and do not force repeated starts.
