No Power
1. Check Controller for a Molex connection;
1.1. Controller w/MOLEX connector and the Vent Damper jumper plug installed, check for
24 volts on terminal 7 (TH) and terminal 5 (GND). If using a Vent Damper, make sure it is
connected and the damper is working, check for 24 volts on terminal 6 (24V) and terminal
7 (TH) to terminal 5 (GND).
1.2. Controller w/o MOLEX connector, check for 24 volts on terminal 6 (24V) and terminal 5 (GND).
2.
Check for 24 volts on the secondary coil of the incoming transformer.

No flame in
trial time
1. Check if the gas is turned “ON”.
2. Check Controller for a Molex connection;
2.1. Controller w/MOLEX connector and the Vent Damper jumper plug installed, check for
24 volts on terminal 7 (TH) and terminal 5 (GND). If using a Vent Damper, make sure it is
connected and the damper is working, check for 24 volts on terminal 6 (24V) and terminal 7
(TH) to terminal 5 (GND).
2.2. Controller w/o MOLEX connector, check for 24 volts on terminal 6 (24V) and terminal 5 (GND).
3.
If no spark, check spark wire and connection to terminal 10 (SPARK) and spark ground to
terminal 4 (GND BURNER).
4. Check if PV is wired to terminal 3 (PV) and common is wired to terminal 2 (MV/PV COM).
5. Check for 24 volts at the PV coil.

Flame
sense circuit
error
1. Check Flame Sensor tip is in the flame. For proper sensing the rod tip must be 3/8” (10mm) to
1/2” (13 mm) in the flame.
2. Check Flame Sensor Circuits;
2.1 For 1 Rod Flame Sense circuit, check Spark/Flame Sensor is wired to terminal
10 (SPARK) and terminal 4 (GND BURNER).
2.2 For 2 Rod Flame Sense circuit, check Flame Sensor is wired to terminal 8 (SENSE) and
terminal 4 (GND BURNER).
3
PV
(Pilot Valve)
circuit error
1. Check for 24 volts on terminal 3 (PV) and terminal 2 (MV/PV COM).
2. Check for 24 volts at the PV coil.
3. Check if PV is wired to terminal 3 (PV) and common is wired to terminal 2 (MV/PV COM).
4. Check gas valve connections, terminals and coil current.
4
MV
(Main Valve)
circuit error
1. Check for 24 volts on terminal 1 (MV) and terminal 2 (MV/PV COM).
2. Check for 24 volts at the MV coil.
3. Check MV is wired to terminal 1 (MV) and common is wired to terminal 2 (MV/PV COM).
4. Check gas valve connections, terminals and coil current.
5 to 9 Control error
1. Review all ground connections and terminals. Make sure you have good continuity on all of the
ground wires (See Ground Continuity Check for details).
2. Check that the Spark Wire is not touching any other control wires and/or metal frame. The
Spark Wire should be isolated 3/8” to 1/2” away from all other control wires and metal frame
(chassis).
3. Check if using fiber core resistive wire for the Spark Wire.
4. Try restarting the power (Call to Heat) to the control module.
5. All ground connections should be cleaned and rust free.
NOTE: If Troubleshooting Guide has been used, and the Control Module is flashing an ERROR CODE, then the
Control Module may be faulty. Replace the Control Module.
NOTE: Ground Continuity Check:
Perform a continuity check on each of the 3 ground wires which are needed and going to the Control Module.
First, turn power off to the ignition module. With a Multi-Meter on ohm’s scale, place a meter’s test probe on any
of the grounds at the Controls Module. With the other Meter’s test probe, place it at the following ground
terminations of each wire:
1. Transformer Ground (COM)
2. Gas Valve (COM) 3. Burner Frame (COM)
Each wire measure should read less than 1 ohm of resistance. If any wire reads more than 1 ohm of resistance,
this is a problem. Replace wire or connections until less than 1 ohm is read on the continuity check.
