Door left open |
An unlimited supply of air to the firebox is bad - it will lead to uncontrolled burning of wood fuel in the firebox that will damage the firebox steel. Please never leave the furnace firebox door open for extended periods of time. The door should only be open for a brief moment to add wood fuel to the firebox and remove ash. |
|
Pump failure |
Remove the silver button on the face of the pump while the pump is in operation to verify the impeller shaft is spinning. If not, replace the pump. See the article on how to diagnose pump failure by clicking on this link HERE. For replacement pump special, call (231) 861-8200. |

High limit switch cannot be reset |
Must wait until the water temp drops below approx. 150 degrees to reset. Also, High Limit Switches have only a limited number of trips in their lifespan. This depends upon how hot and how many times the furnace has high temps. A very high temp situation may kill the switch in one trip. Or it may last 12+ trips. Always have a spare on hand.
