LED Error Indications
If the control module's internal diagnostics detect a fault it
will go into lockout. Spark and both valves will be turned
off. The LED will flash an error code .25 seconds on and
.25 seconds off for each count of the error code with
1 second off between codes. The control will remain in
this condition until power is removed by turning off the call

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.
1. Check for 24 volts on terminal 4 (24V/TH) and terminal 3 GND (24V).
2. Check for 24 volts on the secondary coil of the incoming transformer.
1. Check that the gas is turned "ON".
2. If no spark, check spark wire and connection to terminal 10 (SPARK) and spark
ground to terminal 2 GND (BURNER).
3. Check for 24 volts on terminal 5 PV and terminal 1 GND (MV/PV).
4. Check for 24 volts at the PV coil.
5. Check that the PV is wired to terminal 5 (PV) and common is wired to terminal 1
GND (MV/PV).
6. Check Flame Sensor tip is in the flame. For proper sensing the rod tip must be
3/8" (10 mm to 1/2" (13 mm) in the Flame.
7. Check Flame Sensor is wired to terminal 8 (SENSE) and terminal 2 GND (BURNER).
8. Check that the sense wire is not shorting to ground.
1. Check if pilot flame is distinguished before the call-for-heat cycle is started.
1. Check for 24 volts on terminal 5 PV and terminal 1 GND (MV/PV).
2. Check for 24 volts at the PV coil.
3. Check that the PV is wired to terminal 5 PV and common is wired to terminal 1
GND (MV/PV).
1. Check for 24 volts on terminal 6 MV and terminal 1 GND (MV/PV).
2. Check for 24 volts at the MV coil.
3. Check that the MV is wired to terminal 6 (MV) and common is wired to terminal 1
GND (MV/PV).
1. Check for 24 volts on terminal 7 (R.O. SW) and terminal 3 GND (24V).
2. Check that the rollout switch is wired to terminal 7 (R.O. SW) and the 24V thermostat
line.
3. Check that the rollout switch has continuity because an "open" rollout switch will
cause an error.
1. Review all ground connections.
2. Check if using fiber core resistive wire for Spark Wire.
3. Software error – Restart control module.
1. Check for 24 volts on the secondary coil of the incoming transformer (+10%/-15%
rated voltage).

for heat. A flashing LED error code indicates either a
problem with wiring, or a component not working, or the
control module is faulty. Try to cycle the control again. If
the error repeats then see Table 2 for troubleshooting.
