OVERVIEW
The Thelin Pellet heater is equipped with a long life DC fan motor
(Figure 1). This motor utilizes a special brush material that may
require additional break in time to properly wear in or seat the
brushes. When the motor is new the brush has a contoured end
that allows for minimum contact initially to facilitate the break in.
As this wears the full width of the brush begins to contact the
armature allowing for proper operation.
We have found that a small quantity of motors have not
immediately seated the brushes. The fan motor condition is easily
corrected by dressing the brushes and reinstalling them.
Testing for a fan motor brush problem is accomplished by two
methods. After recycling the heater by unplugging and
reestablishing power. Press the “Fan” switch only. If the fan runs
push the Clean button and allow the motor speed to increase to
full speed. If the motor appears to be operating at less than full
speed cleaning and seating the brushes will be required.
Included in this kit: (2) P/N 00.0035.0213 motor brushes, (1)
instruction.
Tools Required: #2 Phillips screw driver, medium flat blade, small
flat blade, #200 or fine sand paper strip (Figure 2).
Accessing the motor for brush service: The fan motor is
accessed from the bottom of the heater by removing the phillips
screws on the Fan Cover. Remove the convection fan blade
retention clip and blade. Note the access varies based on heater
model and may require removing the fan motor at the housing
(Figure 3).
Removing the wire harness connections : Using care not to
bend the fan blade, carefully use a flat blade screw driver to help
pry off the red and black motor wire terminals (Figure 3). Note
the brush holders have a corresponding red and black base to
confirm wire connections.
Removing the brush caps: Using a small flat blade screw driver
remove one brush cap at a time. Care should be taken as the
brush holder has a spring that forces to the brush onto the
armature. This spring may cause the cap to pop out unless held
firmly (Figure 5).
Removing and dressing the brush: Remove the brush from the
holder by lifting up and sliding the brush and spring clear (Figure
4). Once the brush is clear hold the brush base and carefully take
a couple of swipes across the brush face with fine sand paper
(Figure 5).

NOTE: WHEN SANDING THE FACE OF THE BRUSH DO NOT REMOVE ANY MATERIAL. WE ARE ONLY SCUFFING
THE SURFACE TO ALLOW FOR BETTER BRUSH CONTACT.
Reinstalling the brush: Insert the brush back into the holder. Hold the
terminal tab into the holder. Carefully insert the cap and turn with a small
flat bladed screw driver. Use care not to cross thread the cap. Once the
cap is threaded lightly tighten against terminal tab (Figure 6).
Repeat service on lower brush.
Assembly: Reconnect motor wires to red and black terminals. Check fan
blade for bent blades by spinning by hand. If blades are not aligned
carefully bend back into place.
Carefully reinstall fan cover and confirm fan alignment and the fan blade
turns freely without hitting the shroud.
After completing the installation of the rear panel and tightening all the
phillips screws. Plug the heater back into AC power and test run by
running fan motor on “Fan” setting for 2 minutes and then running on
“Clean” for 30 seconds. Open hopper lid and run unit through a
beginning start up by pressing “Low” and allowing fan to ignitor and fan
to start up. If all appears to activate reinstall unit.
