Boards Switches Sensors

Enviro pellet stoves have had several different control/circuit boards over the years based on the model and year of manufacturer. For the Empress FPI and Milan Insert we offer the mother daughter control board combo, part numbers 50-1392, 50-1393, and 50-2088. If you have an Enviro Empress FS, Maxx, Meridian, or Mini pellet stove model we offer control/circuit board, part numbers 50-1690, 50-1655, and 50-1929. We offer Enviro control board 50-1477 which is correct for Empress FS models with a thermostat slide switch, EF5 Evolution – Serial Number 144653 and greater, Meridian FS – Serial Number 168005 and greater, Meridian FPI – Serial Number 168377 and greater, and Mini – Serial Number 150030 and greater. Enviro control board 50-178 is correct for the EF5 (Evolution) – Serial Number 144652 and Previous, Meridian FS – Serial Number 168004 and Previous, Meridian FPI Insert – Serial Number 168376 and Previous, Mini – Serial Number 150029 and Previous, and Windsor – All serial numbers. Lastly, we carry Enviro control board 50-1369 which fits the Empress FS – Serial Number 160995 and previous (models without the thermostat slide switch). It's very important to cross-reference your part number and review our model notes to ensure you are ordering the correct replacement control/circuit board. With all control boards, we highly recommend a surge protector of at least 1000 joules to be in place for prevention of power surges and electrical spikes.

Enviro EF1, EF2, EF3, EF4, EF5 (Evolution), Empress FS, Meridian, Mini, P3, P4, and Solus pellet stove models will use vacuum switch EF-017. We offer both OEM and aftermarket options for this vacuum switch. Enviro Empress FPI, M55, Maxx, Milan Insert, and Omega pellet stove models will use vacuum low pressure switch, part 50-1390. The vacuum switch is a safety sensor detecting pressure in the firebox and exhaust vent flue pipe. Any air losses or air blockages can trip the vacuum switch and shut down power to the auger feed motor. When inspecting or replacing your vacuum switch, carefully inspect the tubing hose and replace if there are cracks or if it has become brittle. Learn more about vacuum switches in our video below.

Virtually all Enviro pellet stove models will use the ceramic fan temp sensor low limit switch, part EC-001. This switch is normally open and will close as the unit heats up allowing the room-air blower fan to turn on. We offer both OEM and aftermarket replacements for this safety snap switch and the high limit switch. Almost every Enviro pellet stove will have a 200 degree high limit switch with manual reset, part number EF-016. This switch is normally closed and will open if temperatures exceed 200 degrees shutting off power to the auger feed motor. If this switch trips, there is a button in the middle to manually push/reset once the unit is cooled down. If you are experiencing issues with your high limit switch frequently tripping, inspect your convection fan/distribution blower for proper function, and perform a thorough cleaning on your stove and exhaust vent flue pipe. Learn about limit switches in our video below.
