Why won’t my pellet stove shut off?
As a safety feature, your appliance’s convection and combustion blowers will continue to operate even if your appliance is in the “OFF” position or your thermostat has been turned down. They will shut off once they no longer sense heat in the firebox, thus protecting your home from any unwanted re-ignitions.
If your appliance still does not shut down long after operation, contact your local Harman dealer. Do not unplug your appliance if this problem persists. Unplugging your stove can damage the appliance’s electrical components.
