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.
Trouble Shooting Guide
Loose wire or connector.
Check all wires and connectors that connector to the auger
motor, high limit switch, and the Molex connector.
Bad control board.
If the fuse is good, the wires and connectors check out good, and
the high limit switch did not trip, test for power going to the auger
motor. If there is not a full current going to the auger motor when
the fuel feed light is on, you have a bad control board.

Possible Causes Possible Remedies: (Unplug stove rst when possible)
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.
