Error Code C-A2
BLDC motor operation error - Cooling fan or air intake motor malfunction
Moderate
Address soon - your appliance may not work properly
What This Means
Disconnected motor harness; Faulty BLDC cooling fan motor; Faulty BLDC air intake motor; Low voltage to motor (below 10V DC); Defective BLDC Fan PCB; Defective Main PCB
How to Fix
- 1
Determine which motor is faulty from display location (Upper=Cooling, Lower=Air intake)
- 2
Check wire harness connections
- 3
Measure voltage at CN200 pins 1-3 and 4-6: should be 10-14 VDC
- 4
If voltage low, check BLDC Fan PCB and Main PCB
- 5
Operate self-clean mode and check error after 2 minutes
- 6
Measure cooling fan voltage at pins 5-7
- 7
Measure air intake motor voltage at pins 1-4
- 8
Replace BLDC motor or Fan PCB as needed
