Select Your IronStrike Pellet Model

Iron Strike pellet stove control boards, switches, and safety sensors. Iron Strike manufactured the Bella, Cascade, Montage 32FS, Winslow PS40, and Winslow PS40 pellet stoves. Iron Strike continues to manufacture the Winslow and Winslow PI (previously the PS40 and PI40). We continue to carry and stock Iron Strike control boards, limit switches, and safety sensors that are available from factory.

Depending on your Iron Strike pellet stove model, there are different control boards/circuit boards for correct replacement. The circuit board essentially controls all functions of the stove during start-up, operation, and cool down. We highly recommend a surge protector to be in place to prevent voltage spikes from harming the control board when the stove is plugged in. Currently we carry the H5978 control board for the Winslow PS40 and PI40, and the H7626 control board for the Bella Cast model. The Montage 32FS control board is not currently available from the factory.

Iron Strike pellet stoves will have limit switches and a vacuum/pressure switch which are designed as safety sensors. There are several variances in switches depending on your model. The high limit switch is a normally closed snap switch that will open if temperatures exceed the limit point. When this switch trips it will shut down the fuel feed. Most common causes for this switch to trip would be ash blockage in the stove/venting causing high flames and pellets backing up in the burnpot and up the drop chute. The other would be the convection fan blower not operating correctly or not operating at all to disperse the heat into the room.

Low limit switches are normally open, closing to make connection once the indicated temperature is reached. Low limit snap switches are often used as the Proof of Fire switch to lock in the auger feed after start-up, exhaust limit switch to shut down the exhaust fan once the stove is cool, and on the convection fan blower to turn that blower on once the stove is warm enough. Take a look at our videos below for further information on limit switches/snap switches/thermodiscs.

The Iron Strike vacuum switch, also referred to as the pressure switch or low draft switch, senses pressure in the firebox and exhaust. As a safety sensor, the vacuum/pressure switch will shut down the fuel feed auger if proper pressure is not sensed in the firebox or exhaust. Most common areas to check when seeing a vacuum switch error will be the front door gasket, ash pan gasket, and glass gasket to ensure there is proper seal. From there, ash accumulation in the stove, exhaust manifold, and exhaust venting should be checked and cleaned. Additionally, if our combustion blower is not running at proper voltage, it will not be able to lock in the vacuum switch. We offer two different vacuum switches for Iron Strike models in the event the switch itself is faulty and needs to be replaced. Learn more about vacuum switches and troubleshooting in our video below.

FOR TROUBLESHOOTING ONLY, we can bypass a safety switch to determine where the issue may be. See our video below on how to troubleshoot switches and sensors with a jumper wire.
