What to do if CleaverBrooks CBEX Elite Boiler burner does not start?
- JJames SmithAug 3, 2025
If the burner on your CleaverBrooks Boiler isn't starting, there are several potential causes to investigate. First, ensure that the main disconnect switch is not open, check for any blown control circuit fuses, and verify that all electrical connections are secure. If the program relay (flame safeguard) safety switch requires resetting, reset it. Also, check pressure or temperature settings, water level, and fuel pressure. Finally, ensure the fuel valve auxiliary switch is closed.
