High limit switch keeps tripping
Possible Causes Possible Remedies: (Unplug stove rst when possible)
The convection blower is overheating and tripping the
internal temperature shutoff.
Clean any dust off of the windings and fan blades. If oiling the
blower does not help, the blower may be bad.
The stove is being left on the highest setting for extended
periods of time.
If operating the heater on the highest heat setting, the room
temperature could increase enough and lead to potential
overheating situations. If this happens, try operating at a lower
heat setting.
Fuel other than wood pellets is being burned in the stove.
This pellet stove is designed and tested to use wood pellets.
Check for signs of fuel other than wood pellets. No other
types of fuel have been approved for this pellet stove. If there
are signs of other types of fuel being used, stop using them
immediately.
Power surge or brown out situation.
A power surge, spike, or voltage drop could cause the high
limit switch to trip. Check to see if a surge protector is being
used on the stove. If not, recommend one to the consumer.
High limit switch is malfunctioning. If the other items check out OK, replace the high limit switch.

Stove or vent pipe is dirty, which restricts airow through
the burnpot.
Follow all cleaning procedure in the maintenance section of
the owner’s manual.
Vent pipe installed improperly.
Check to make sure the vent pipe has been installed according
to the criteria in the owner’s manual.
Air damper is set too far in (closed) for a higher setting.
Pull the damper knob farther out away from the side of the
stove and try to burn the unit again.
Burnpot holes are blocked. Remove the burnpot and thoroughly clean it.
Air damper is broken.
Visually inspect the damper assembly. Make sure the damper
plate is attached to the damper rod. When the damper rod is
moved the plate should move with it.
Blockage in air intake pipe.
Visually inspect the air intake pipe that leads into the burnpot
for foreign material.
Combustion blower is not spinning fast enough.
Test the RPM on the blower after the blades have been
cleaned. The RPM should be approximately 3000 RPM.
Bad Pellets. (Applies to GLASS “SOOT’S” UP AT A VERY FAST
RATE Only)
The brand of pellets or the batch of pellets that are being used
may be of poor quality. If possible, try a different brand of
pellets. You might also want to try a brand that is made from
a different type of wood (softwood vs. hardwood). Different
woods have different characteristics when being burned.
