Raypak Error FLAME: False Flame Detected
The control sees a flame signal when no flame should be present (before ignition or after the gas should be off). On XTherm the display reads FLAME; on digital/PIM units it reads FFL; the instruction is to shut off the gas supply and recycle power. We diagnose and repair it across Greater Vancouver — same-day and after-hours.

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 FLAME
- Gas valve (pilot or main) stuck partially open
- Flame sensor or ignition/ground wiring shorted or contaminated
- Lingering combustion / slow gas valve closure
- Faulty flame sensor circuit
- Ignition control board fault
What you can safely check
- If you smell gas, leave the area and call your gas utility — do not touch the unit
- Otherwise note the code and call a licensed HVAC technician; do not keep resetting
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.
Error FLAME usually leaves you without heat or hot water and can indicate a safety-related fault. Don't keep resetting it — call for priority after-hours Raypak repair.
