Why is my US Stove Company 5660 high limit switch keeps tripping?

  Matthew AllenAug 22, 2025
  If the high limit switch on your US Stove Company Stove keeps tripping, it could be due to several reasons: * The convection blower may be overheating. Try cleaning any dust off the windings and fan blades. If that doesn't help, the blower might be bad. * The stove might be running on the highest setting for too long, causing overheating. Try operating it at a lower heat setting. * You might be burning fuel other than wood pellets. This stove is designed for wood pellets only. Stop using any other types of fuel immediately. * A power surge or brownout could be the culprit. Check if you're using a surge protector and consider getting one if you aren't. * The high limit switch itself may be malfunctioning. If none of the other solutions work, it might need to be replaced.

  If you're experiencing a smoke smell coming back into your home from your US Stove Company Stove, it could be due to: * A leak in the vent pipe system. Inspect all vent pipe connections and seal them with RTV silicone (rated 500°F or higher) and UL-181-AP foil tape. Also, ensure the square-to-round adapter on the combustion blower is properly sealed with the same RTV. * A bad gasket on the combustion blower. Inspect both gaskets to ensure they are in good condition.

Why does my US Stove Company Stove convection blower shuts off and comes back on?
- R
  richardsjoshuaSep 12, 2025
  If the convection blower on your US Stove Company Stove shuts off and then comes back on, it could be due to: * The convection blower overheating and tripping the internal temperature shutoff. In this case, clean any dust off the windings and fan blades. If cleaning the blower does not help, the blower may be bad. * A circuit board malfunction. Test the current going to the convection blower. If there is power being sent to the blower when it is shut off, then the control board is fine. If there is NOT power being sent to the blower when it shuts off during operation, then you have a bad control board.

  When your US Stove Company Stove flashes "E5" upon being turned on, it indicates that the T-stat sensor has become unplugged from the control board. Check to see if the sensor is unplugged. If the sensor is not unplugged then the sensor is damaged or has a short and will need to be replaced.
