Boards Switches Sensors

Pacific Energy PS45 Warmland, True North TN40, True North TN40 Insert, and the Warmland Classic will use a ceramic proof of fire low limit switch. Generally this switch will be mounted on the exhaust fan housing. As the stove goes through start-up and the limit switch reaches 110 degrees Fahrenheit, the switch will close allowing the fuel feed motor to come on as the stove transitions from start-up mode to normal operation. As the stove is shut down and the exhaust motor cools, the switch will auto re-open at the determined temperature. If your auger feed motor is not locking in after start-up or your exhaust fan is not shutting down once the stove is completely cool, we will want to take a closer look at this limit switch.

Earlier models used a larger low limit switch for the proof of fire. The limit switch replacing part number 5027.171 is a 3/4″ diameter, recessed mount switch. Be sure to double check your current switch to ensure you are ordering the correct replacement.

The Pacific Energy PS45 Warmland, True North TN40, True North TN40 Insert, and the Warmland Classic models will use a 200 degree high limit switch with a manual reset. This switch is normally closed and will open if temperatures exceed 200 degrees Fahrenheit. This safety switch is generally tripped when we have an out of control fire or when our convection fan/distribution blower is failing/failed and the stove is unable to disperse the heated air. If your high limit switch is tripping, we suggest a thorough cleaning of your stove and venting and to double check the operation of your convection fan.
