Raypak fault codes can vary by model and series. Use this as a guide — the same code can have more than one cause. Our Technical Safety BC–licensed technicians read the code, confirm it against your unit's manual, and diagnose the true cause before any repair.
Likely causes of Raypak error ROL
- Blocked or restricted heat exchanger / flue passages
- Blocked or obstructed venting causing downdraft
- Combustion air problem or dirty burner
- Damaged wiring at the rollout switch
- Wind exposure at the vent terminal
What you can safely check
- Stop using the boiler and call a technician — this is a combustion safety fault
- From outside, check that the vent terminal is clear of snow, debris, or nests
Beyond these checks, do not open the unit or touch gas/electrical parts — BC law requires a licensed gas fitter. Call us for a proper diagnosis.
