Rheem Error F029: Gas valve fault
The gas valve coil resistance is out of specification, so the control cannot trust the valve to open and close safely and locks out the burner. We diagnose and repair it across Greater Vancouver — same-day and after-hours.

Rheem 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 Rheem error F029
- Failed gas valve coil (resistance out of spec)
- Loose or damaged gas-valve wiring harness
- Control module driving the valve has failed
What you can safely check
- Confirm the manual gas shutoff to the boiler is open and other gas appliances work
- Do not open the unit; a technician must test/replace the gas valve
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.
