**Occasional** · Professional repair only

## What you will notice

- Code 139
- Control panel behind the top-left door running hot
- Intermittent panel lockouts

## What is usually behind it

- Defective or worn door rope seal leaking heat (most common)
- Baking oven door left open or not fitting correctly (common)
- Missing rubber bungs in the thermocouple conduits (common after a previous repair)
- Towels or cloths draped over the control panel door (customer behaviour)
- Degraded cooker insulation (age related)

## How a technician diagnoses it

1. Inspect all door rope seals. Note the correct configuration: baking and simmer oven doors have a GAP in the rope seal; the roasting oven door has NO gap.
2. Check door fit and hinge adjustment.
3. Confirm every thermocouple conduit has its sealing bung fitted.
4. Check insulation condition.
5. Educate the customer about draping cloths over the control door.
