3. ...continued | d. Damaged pilot | Verify that ceramic insulator around the sensor rod is not cracked, dam- |
| assembly or dirty | aged, or loose. Verify connection from sensor rod to white sensor wire. |
| sensor rod. | Clean sensor rod with emery cloth to remove any contaminants that may |
|
| have accumulated on sensor rod. Verify continuity with a multimeter with |
|
| ohms set at lowest range. |
|
|
|
| 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 po- |
|
| sition. 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. |
4. Pilot sparks, but | a. Correct gas supply. | Verify that incoming gas line ball valve is “open”. Verify that inlet pressure |
Pilot will not light. |
| reading is within acceptable limits, inlet pressure must not exceed 14 in. |
