Error Code 15
Inverter power module temperature exceeded safe limit and shut down
Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: 96 (RR39/RR14/RZ32/RZ11/RQ32)
What This Means
IPM overheating from sustained high current; Inverter board insufficient cooling; Compressor operating at overload; Thermal sensor fault on IPM; Excessive ambient temperature
What actually causes this:
The inverter board controlling the compressor overheated from running at high current draw or poor ventilation
First Thing to Check
Check that the inverter board has adequate cooling air flow and heatsink is clean
Parts Involved
How to Fix
