What This Means
Wire harness disconnected to cooling or air intake motor; Failed BLDC motor (cooling fan or air intake); Failed Sub PCB
How to Fix
- 1
Identify display location: upper = cooling motor issue, lower = air intake motor issue
- 2
Check wire harness connection
- 3
Verify voltage at Sub PBA CN200 pins 1-3 and 4-6: Cooling Fan 10-14VDC, Air Intake Motor 0.4-0.6VDC
- 4
If harness disconnected, reconnect
- 5
Run Self Clean cycle and check status after 2 minutes
- 6
If still failing, replace BLDC motor
- 7
If voltage supply is absent, replace Sub PBA or Main PBA
