Error Code 42E
Freezer compressor inverter power module detected a fault
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: 42E
What This Means
IPM (FNE41060) defective on F Room inverter PCB; Overcurrent condition detected; Bootstrap capacitor not charged; Short circuit in compressor winding
What actually causes this:
IPM module on the inverter board failed, often from a voltage spike or compressor winding short.
First Thing to Check
Check that the inverter PCB LED is off (indicating a fault) and that no visible burn marks are present on the PCB.
Parts Involved
How to Fix
- 1
Inspect inverter PCB IPM FNE41060 for damage
- 2
Check freewheeling diode voltages per SPM voltage table
- 3
Check bootstrap capacitor charging
- 4
Verify compressor winding resistance (check for short)
