4. Ignitor not functioning.
5. Gas combination supply valve not opening.
Burners Produce Carbon Deposits
1. Wrong orifice size.
2. Wrong gas supply.
3. Incorrect pressure at supply.
4. Not enough primary air.
Water Flows into Cooking Compartment
Probes not sensing water, thereby not operating fill solenoid.
1. Scale build-up on operating probe inside the generator.
2. Water fill solenoid valve is not closed. Check for scale or foreign particles lodged in diaphragm or core tube of valve.
These problems are an indication of severe harmful water conditions which should be corrected immediately to avoid
