Parts Involved
How to Fix
- 1
Check MAIN PCB connector CN79 is fully seated
- 2
Disconnect CN79 and measure resistance between CN79 #6 (Pink) and CN79 #10 (White) — should be 72 ohm ±7%
- 3
Also check CN78 #5 (Black) to CN78 #4 (Brown) for supplemental measurement
- 4
0 ohm = short; infinite = open (wire or heater disconnection)
- 5
Check IC01 MICOM pin #6 voltage — should be 3.5V–4.8V when heater is off, drops to 0V when heater activates
