What the control is telling you

Compressor drive fault: inverter compressor ac current protection.

Applies to: Gree GMV6 Ultra Heat Mini VRF 36-60k (GMV-V..WL/C-T(U))

Likely causes

  • Compressor winding fault
  • Poor refrigerant flow or dirty coils/filters
  • Supply voltage problem
  • Drive / main board fault

Test and repair steps

  1. Warning: Turn off power and wait for the board to discharge before testing.
  2. Measure compressor windings equal resistance between terminals and open to ground.
  3. Check refrigerant flow and clean filters, coils and blower wheels.
