Error Code C-30
PCB sensor opened or shorted — oven sensor error at PCB side
Moderate
Address soon - your appliance may not work properly
What This Means
PCB-side sensor circuit open or shorted; Failed oven temperature sensor; Poorly seated connectors CNP207, CNP208, or CNP209 on PCB
How to Fix
- 1
Disconnect power and remove the PCB
- 2
Measure oven sensor resistance: 1080 ohm at room temperature
- 3
Check oven sensor harness connections at the PCB
- 4
Replace and reconnect oven sensor if faulty
- 5
Measure PCB sensor resistance: 3900 ohm at room temperature
- 6
Ensure harness connectors are fully seated in CNP207, CNP208, and CNP209
- 7
Repair or replace the PCB
