PELPRO TROUBLESHOOTING MANUAL
INTRODUCTION
The purpose of this troubleshooting guide is to provide step by step procedures for diagnosing issues with the PelPRO
PPC90 and TSC90. A digital or analog multimeter will be required for many of the troubleshooting steps in this guide.
When troubleshooting with the multimeter, it’s important to disconnect the appliance from wall power while locating the
electrical connections that need to be checked. Connect the multimeter to the test locations detailed in this guide and then
plug the appliance back into wall power. Take care to avoid letting any exposed wires or connectors from contacting the
metal chassis of the Appliance or from touching exposed skin. The appliance is energized with 115VAC power from the wall
and there is a risk of shock or electrocution. If you are not familiar or comfortable working with energized electrical circuits,
please contact a certied NFI Installer or certied electrician to complete that portion of troubleshooting.
When instructed to check a appliance for power from the control board, the multimeter will need to be set to check Voltage,
often displayed as “V” on the meter. If the meter is not auto-sensing, AC voltage will need to be chosen when specied in
the instructions. AC voltage is also sometimes shown as ~ V on multimeters. If instructed to check VDC, DC voltage will
have to be chosen on the multimeter. Voltage checks are typically used when motors and blowers are not running and we
are attempting to determine if the component is bad or is the control board is not sending power to the component.
Some components can be veried for functionality by checking the resistance of the part. Igniters and fuses are the most
common parts that can be veried by resistance checking with a multimeter. Resistance is measured in ohms (Ω) and
most multimeters will have that symbol next to the resistance setting. Unlike voltage, resistance is always measured with
the appliance completely deenergized from wall power. There is no risk of shock or electrocution when the appliance is
unplugged from wall power and components are being veried for resistance. When resistance is being checked, this
manual will provide an expected resistance in Ω, however a number slightly above or below the specied value does not
indicate a bad component. If the multimeter shows MAX or Out of Range, this indicates innite resistance, meaning an open
circuit and a bad component. A resistance of 0 ohms for a component indicates an electric short circuit and again a bad
component.

COMPONENT LOCATIONS
FEED MOTOR
The feed motor is located on the back of
the unit towards the bottom. Removing
the rear screen and left side panel is the
best way to access the motor.
Once access is gained, simply pulling the
pin on the auger shaft will release the
feed motor.
COMPONENT LOCATIONS
IGNITER
The igniter is located at the back of
the firebox in the middle.
Removing the left access panel
will allow you to see it. There is a
Phillips head screw holding the
igniter in place.
Screw location
COMPONENT LOCATIONS
EXHAUST BLOWER
Remove the left side panel to access
the blower. A Phillips head screwdriver
will be needed to remove the blower
from the housing.
COMPONENT LOCATIONS
CONVECTION BLOWER
Remove the right side panel to access
the blower. Two wing nuts hold it in
place. Removal is a little tight, so the
blower will need to be rotated a little to
get it out. Removing the vacuum
switch is a good option if you need a
little more room taking the blower out.
Wing nuts
COMPONENT LOCATIONS
VACUUM SWITCH
Remove the right side panel. Two
Phillips screws hold it in place.

EXHAUST TEMP PROBE
Remove the left side panel to access
the probe. Two Phillips head screws
hold it in place.

#3 SNAP DISC
Remove the left side panel to access
the snap disc. Two Phillips head
screws hold it in place.
COMPONENT LOCATIONS
HOPPER SWITCH
It is located under the hopper lid on the right
side the stove. The right side panel will need to
be removed to access the 2 mounting screws for
the hopper switch bracket.

ERROR NR: 05
REFER TO MANUAL
Error codes will look
like this on the display
ERROR CODE DEFINITIONS
Code #1 Fuel Feed Alarm. Most likely the appliance ran out of fuel or the ames are adjusted
too low.
Code #2 Exhaust Temperature is above or below the acceptable range. Exhaust probe has
failed or the ames need to be adjusted.
Code #3 Ambient Temperature is above or below the acceptable range.
Ambient probe has failed.
Code #4 Missed Ignition Alarm. Appliance has either ran out of fuel or the repot needs to
be cleaned. Also it is possible that the igniter has failed if the appliance is clean.
Code #5
Digital Display Communication Alarm. Appliance lost power while the appliance
was running or there was a bad connection from the display to the control board.
Board may need replaced.
Code #7
Exhaust temperature over heat alarm. Appliance got too hot. Check the heat
exchanger and exhaust system for obstructions. Make sure the ame height is
correct.
