HIGH LIMIT SWITCH KEEPS TRIPPING
Remove the burnpot and thoroughly clean it.
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.
Visually inspect the air intake pipe that leads into the burnpot
for foreign material.
Time the fuel feel light at each setting (after the stove has
completed the startup cycle). Make sure the times match the
auger timing chart. If the auger motor runs constantly, the
board is bad.
Test the RPM on the blower after the blades have been
cleaned. The RPM should be approximately 3000 RPM.
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.
Use the “Reset Trim” button to increase the low feed rate
setting. If the 1 & 3 are on, the stove is currently on the lowest
setting. If only the 1 light is on, the stove is in the default
(medium) setting. If the 1 & 4 lights are on, the stove is in the
high trim setting for the low feed rate. If the stove is being
burned on one of the two lower settings, advance to the next
trim setting and try burning the stove.
5.- Burnpot holes are blocked.
6.- Air damper is broken.
7.- Blockage in air intake pipe.

Clean any dust off of t he windings and fan blades. If cleaning
the blower does not help, the blower may be bad.
The highest heat level setting is designed for use over short
periods of time. Burning the stove on the highest setting for
longer than 1—2 hours could lead to potential overheating
situations.
Bosca pellet stoves are designed and tested to use wood pellets.
While it is possible to burn a corn mixture (corn mixed in with
wood pellets) in the stove, it is not recommended to burn
above the number 3 heat level. Check for signs of fuel other
than wood pellets. If there are signs of corn being used, find
out what mixed was being used and what setting. No other
types of fuel have been approved for Bosca pellet stoves. If
there are signs of other types of fuel being used, advise the
consumer to stop using them immediately.
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.
If the other items check out ok, replace the high limit switch.
