Critical
Stop using immediately - risk of damage or safety issue
Also displayed as: R3 LED blink
What This Means
Compressor fails to start; Short circuit between compressor terminals; Short between IPM (Intelligent Power Module) pins; IPM module fault detected; Abnormal current detected; Motor restriction or locked rotor; Excessive RPM detected; Shunt resistance failure; Low input voltage; Over voltage condition
What actually causes this:
Usually caused by electrical failure in the inverter circuit, compressor winding failure, or lack of proper input voltage
First Thing to Check
Verify the unit has proper 115V AC input power and measure the voltage at the compressor terminals
Parts Involved
How to Fix
- 1
Check for short between compressor terminals
- 2
Check for short between IPM pins
- 3
Inspect compressor and refrigeration cycle integrity
- 4
Measure input voltage to unit
- 5
Check shunt resistance (R1) condition
- 6
Turn off refrigerator for 5 minutes then turn on
- 7
Observe if error clears or persists
