TROUBLESHOOTING

WARNING

Fire, Explosion, or Electrical Shock Hazard.
Can cause severe injury, death or property 
damage.

Do not attempt to modify the physical or electrical 
characteristics of this device in any way. Replace 
it if troubleshooting indicates a malfunction.

IMPORTANT

1. The following service procedures are provided 

as a general guide. Follow appliance manufac-
turer’s service instructions if available.

2. Meter readings between the gas control and igni-

tion control module must be taken within the trial 
for ignition period. Once the ignition control mod-
ule shuts off, it must be reset by setting the ther-
mostat down for at least 30 seconds before 
continuing.

3. If any component does not function properly, 

make sure it is correctly installed and wired 
before replacing it.

4. The ignition control module cannot be repaired. 

If it malfunctions, it must be replaced.

5. Only trained, experienced service technicians 

should service intermittent pilot systems.

6. After troubleshooting, check out the system 

again to be sure it is operating normally.

The general troubleshooting sequence is as follows:

1.

Refer to “LED Status and Troubleshooting” on 
page 19 for LED status codes.

2.

Perform the “Checkout” on page 15 as the first step 
in troubleshooting. 

3.

Check the troubleshooting guide (Fig. 11 on 
page 21) to pinpoint the cause of the problem. 

4.

If troubleshooting indicates an ignition problem, see 
Ignition System Checks below to isolate and correct 
the problem.

5.

Following troubleshooting, perform the “Checkout” 
on page 15 again to be sure system is operating 
normally.

Ignition System Checks

Step 1: Check Ignition Cable.

Make sure:

1.

Ignition cable is not damaged, cracked, burned, or 
dirty. Replace if necessary.

2.

Ignition cable does not run in contact with any metal 
surfaces.

3.

Ignition cable is no more than 36 in. (0.9 m) long.

4.

Connections to the ignition control module and to 
the igniter or igniter-sensor are clean and tight.

5.

Ignition cable provides good electrical continuity.

STEP 2: Check Ignition System Grounding.

Nuisance shutdowns are often caused by a poor or erratic 
ground. A common ground, is required for the ignition 
control module and the pilot burner bracket.

1.

Check for good metal to metal contact between the 
pilot burner bracket and the main burner.

2.

Check the ground circuit from the GND (BURNER) 
terminal on the ignition control module to the pilot 
burner. Make sure connections are clean and tight. 
If the wire is damaged or deteriorated, replace it 
with 14- to 18-gauge, moisture-resistant, thermo-
plastic insulated wire with 221°F (105°C) minimum 
rating.
a. Check the ceramic flame rod insulator for 

cracks or evidence of exposure to extreme heat, 
which can permit leakage to ground. Replace 
pilot burner/igniter-sensor and provide shield, if 
necessary.

b. If the flame rod or bracket is bent out of position, 

restore to correct position.

STEP 3: Check Spark Ignition Circuit. 

You will need a short jumper wire made from ignition 
cable or other heavily insulated wire.

1.

Close the manual gas valve.

2.

Disconnect the ignition cable at the SPARK terminal 
on the ignition control.

WARNING

Electrical Shock Hazard.
Can cause severe injury, death or property 
damage.

When performing the following steps, do not touch 
the stripped end of jumper or SPARK terminal. 
The ignition circuit generates over 10,000 volts 
and electrical shock can result.

3.

Energize the ignition control module and immedi-
ately touch one end of the jumper firmly to the GND 
terminal on the ignition control module. Move the 
free end of the jumper slowly toward the SPARK 
terminal until a spark is established.

4.

Pull the jumper slowly away from the terminal and 
note the length of the gap when sparking stops. 
Check Table 12 below.

Table 12. Arc Troubleshooting.

Arc Length

Action

No arc or arc less 
than 1/8 in. (3 mm)

Check external fuse, if provided.
Verify power at the ignition 
control module’s control input 
terminal. Replace control if fuse 
and power are okay.

Arc 1/8 in. (3 mm) 
or longer

Voltage output is okay.
