5 Troubleshooting
With proper installation, operation, and maintenance your gas appliance will provide years of

Symptom | Possible Causes | Corrective Actions | |
1. The | a. Incorrect wiring. | Verify "S" wire (white) for sensor and "I" wire (orange) for ignitor are | |

| connected to correct terminals on module and pilot assembly. Reversed wires | |

| at the module may cause system to make sparking noise, but spark may not | |

| be present at pilot hood. | |
| b. Loose | Verify no loose connections or electrical shorts in wiring from module to pilot | |
| connections or | assembly. Rod closest to pilot hood should be ignitor. Verify connections | |
| electrical shorts in | underneath pilot assembly are tight; also verify connections are not grounding | |
| the wiring. | out to metal chassis, pilot burner, pilot enclosure, mesh screen if present, or | |
|
| any other metal object. | |
| c. Ignitor gap is too | Verify gap of igniter to pilot hood. The gap should be approximately .17 inch | |
| large. | or 1/8 inch. | |
| d. Faulty module. | Turn ON/OFF rocker switch or wall switch to OFF position. Remove ignitor | |
|
| wire "I" from module. Place ON/OFF Rocker switch or wall switch in ON | |
|
| position. Hold ground wire about 3/16 inch away from "I" terminal on module. | |
|
| If there is no spark at "I" terminal module must be replaced. If there is a spark | |
|
| at "I" terminal, module is fine. Inspect pilot assembly for shorted sparker wire | |
|
| or cracked insulator around electrode. | |
2. Pilot won't light, | a. Transformer | Verify that transformer is installed and plugged into module. Check voltage of | |

| ON position. Acceptable readings of a good transformer are between 3.2 and | |
|
| 2.8 volts AC. | |
| b. A shorted or | Remove and reinstall the wiring harness that plugs into module. Verify there is | |
| loose connection in | a tight fit. Verify pilot assembly wiring to module. Remove and verify continuity | |
| wiring configuration | of each wire in wiring harness. | |
| or wiring harness. |
| |
| c. Improper wall |

| switch wiring. |
| |
| d. Module not | Verify black ground wire from module wire harness is grounded to metal | |

| e. Faulty module. | Turn ON/OFF rocker switch or wall switch to OFF position. Remove ignitor | |
|
| wire "I" from module. Place ON/OFF Rocker switch or wall switch in ON | |
|
| position. Hold ground wire about 3/16 inch away from "I" terminal on module. | |
|
| If there is no spark at "I" terminal module must be replaced. If there is a spark | |
|
| at "I" terminal, module is fine. Inspect pilot assembly for shorted sparker wire | |
|
| or cracked insulator around electrode. | |
3. Pilot lights but | a. A shorted or | Verify all connections to wiring diagram in manual. Verify connections | |
