  Michael GuzmanJul 25, 2025
  If your Daikin Heat Pump isn't operating, several factors could be at play. First, check for a power failure and restore power if necessary. Ensure the equipment power supply is turned on and that the power plug is correctly connected and making good contact. Also, verify that the circuit breaker is activated. In addition, the unit might have shut down due to an alarm; resolve the alarm condition and reset the unit.

How to fix a Daikin LXE10E-A14 compressor that buzzes but does not operate?
- E
  Elizabeth WadeAug 15, 2025
  If the compressor in your Daikin Heat Pump buzzes but doesn't start, it could be due to a few potential issues. Check for an open phase and restore it. The compressor may also be locked, in which case you should unlock it. Low supply voltage could also be the cause, so ensure that the voltage supply is adequate. Lastly, the motor coil might be burned out or short-circuited, requiring replacement.
