Why is my Myson Heater fan not working in heating mode?
- KKathryn SmithJul 26, 2025
The fan might not be working because the unit is switched off (turn it on), the room thermostat is not calling for heat (turn up the room thermostat), the unit isolating valves are shut (open the valves), or the water temperature is below 30°C (ensure boiler, pump and other central heating equipment is working correctly, if not contact your installer. Note: Operation of fan can be checked by switching to fan only setting).
