John Wood Air Pressure Switch Replacement in Greater Vancouver
Genuine John Wood air pressure switch, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Air Pressure Switch on Your John Wood Boiler
The air pressure switch proves the combustion fan is moving air and the flue is clear before the control allows ignition. A failed switch or blocked sensing tube is a frequent cause of no-heat lockouts.
On John Wood systems — including models such as Envirosense, JW Power Vent, JW Direct Vent — a failing air pressure switch often shows up as no hot water or related symptoms. We diagnose it precisely and install the correct genuine John Wood part.
