Error Code C-30
PCB sensor opened or PCB sensor shorted (onboard NTC thermistor fault)
Moderate
Address soon - your appliance may not work properly
What This Means
Onboard PCB NTC thermistor open or shorted; Faulty oven temperature sensor; Damaged harness connections at CN320 on Main PCB
How to Fix
- 1
Disconnect power and remove back cover
- 2
Measure PCB sensor resistance (normal: 3900 ohm at room temperature)
- 3
Measure oven sensor resistance (normal: 1080 ohm at room temperature)
- 4
Check oven sensor harness connections at Main PCB CN320
- 5
Check Control Relay, Bake and Broil harness connections to PCB
- 6
Repair or replace PCB if traces are damaged
- 7
Replace and reconnect oven sensor if faulty
