Error Code C8
Internal temperature rises abnormally high during operation
High
Needs prompt attention - may cause further issues if ignored
What This Means
Thermostat stuck in on position; Relay failure; Sensor reading incorrect; Control logic failure
How to Fix
- 1
Check oven temperature rises over 500°F within 10 minutes in room temperature
- 2
Verify sensor resistance at room temperature: 1066 ohms normal
- 3
Check D/LB Broil/Bake and Convection relay operation on Main PCB
- 4
Measure any damaged parts on Sub PCB
- 5
Check wire harness connections for damage
- 6
Check connector resistance at Main PCB C1
