US Stove Inconsistent Fuel Feed

Furnace frequently runs out of fuel in the burn pot even though the hopper is full.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Fuel bridging in hopper, Worn auger flighting reducing feed, Incorrect feed rate setting, Excessive fines in fuel

Safety first: Turn off and unplug the furnace before reaching into the hopper.

Steps:

1. Stir fuel: Break up any bridges or crusts in the hopper so fuel can drop into the auger.
2. Screen out fines: Excess fines can pack in the auger. Sift fuel to remove fines or switch to a cleaner brand.
3. Inspect auger: Check for worn or damaged auger flighting that may reduce feed. Replace the auger if significantly worn.
4. Adjust feed rate: Increase the feed setting slightly and observe whether the burn pot stays adequately filled.
