Why does my Bosca SPIRIT 500 Pellet stove shut off and the #3 light flash?

  Terry MoyerJul 31, 2025
  If your Bosca pellet stove shuts off and the #3 light flashes, it could be due to several reasons. First, ensure the hopper is filled with pellets and the lid is securely closed. An open lid prevents pellet feeding. Also, check that the air damper isn't too far open for a low feed setting. Make sure the burnpot is correctly positioned, touching the rear wall of the firebox, and that the burnpot holes are not blocked. Remove the burnpot and clean it thoroughly. Finally, inspect the air inlet, interior chambers, and exhaust system for any blockages, following the cleaning procedures in the maintenance section.

How to prevent glass from sooting up fast in my Bosca pellet stove?

  Robert GuerreroAug 7, 2025
  If your Bosca pellet stove's glass is sooting up quickly, several factors could be responsible. Ensure the stove and vent pipe are clean to maintain proper airflow through the burnpot. Clean the heat exchanger or access baffle clean out. Verify that the vent pipe is installed correctly. Adjust the air damper by pulling the knob farther out. Clean the burnpot holes. Inspect the damper assembly and air intake pipe. You might also test the fuel feed light timing or the combustion blower's RPM after cleaning the blades. Trying a different brand of pellets or using the "Reset Trim" button may also help.

Why Bosca SPIRIT 500 feeds pellets, but will not ignite?

  Thomas LucasAug 18, 2025
  If your Bosca pellet stove feeds pellets but won't ignite, start by pulling the air damper out for startup. Check for any blockages in the igniter tube or its inlet. Ensure the burnpot is pushed completely to the rear of the firebox, so the air intake collar touches the rear wall. Test the igniter element by applying power directly to it. Also, check the voltage going to the igniter during startup to see if the control board is sending power.

Why does the high limit switch keep tripping on my Bosca SPIRIT 500?

  If the high limit switch keeps tripping on your Bosca pellet stove, it could be due to several reasons. Begin by cleaning any dust off the convection blower's windings and fan blades. Avoid leaving the stove on the highest setting for extended periods. Ensure that only wood pellets are being burned in the stove. Check if a surge protector is being used. If none of these address the issue, the high limit switch itself may be malfunctioning and require replacement.

  If your Bosca pellet stove shuts off and the #2 light flashes, start by checking the airflow switch hose and its attachments for any blockages. Disconnect the air hose and blow through it; if blocked, use a wire coat hanger to clear it. Ensure the firebox is properly sealed by closing the door tightly and verifying the gasket's condition. Latch the ash door securely and ensure it seals well. If there's a slider plate for ashes, make sure it's in place. Verify that the vent pipe installation meets the guidelines in the Owner’s Manual. Check the wire connections to the air switch and ensure the gray wires are securely connected at the Molex connector. Finally, confirm the combustion blower is running and that the control board is sending power to it; if not, and after checking all wire conne...
