Troubleshooting Guide
No
LED
“ON”
No Power
1. 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.
1
No flame in
trial time
1. Check if the gas is turned “ON”.
2. 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 terminal 4 (GND BURNER).
4. Check if valve is wired to terminal 3 (VALVE) and common is wired to terminal 2
(VALVE COM).
5. Check for 24 volts at Valve’s coil.
2
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
Valve circuit
error
1. Check for 24 volts on terminal 3 (VALVE) and terminal 2 (VALVE COM).
2. Check if valve is wired to terminal 3 (VALVE) and common is wired to terminal 2
(VALVE COM).
3. Check for 24 volts at the Valve’s coil.
4. Check gas valve connections and terminals.
5. Check gas valve 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.
