TROUBLE SHOOTING GUIDE
BEFORE ATTEMPTING TO TROUBLESHOOT, PURGE YOUR UNIT AND INITIALLY LIGHT THE PILOT AND THE MAIN BURNER WITH THE GLASS DOOR REMOVED.
SYMPTOM | PROBLEM | TEST SOLUTION |
Pilot will not light. | - Wiring | Verify the "S" wire for the sensor and the "I" wire for the ignitor are |
Makes noise with no |
| connected to the correct terminals (not reverse) on the module and |
spark at pilot burner | - Loose connection | pilot assembly. |
| Verify no loose connections, electrical shorts in the wiring or ground | |
| - Module | out to any metal object. |
| Turn the ON/OFF switch to the "OFF" position. Remove the igniter | |
|
| wire "I" from the module. Place the ON/OFF switch to the "ON" posi- |
|
| tion. Hold a grounded wire about 3/16" away from the "I" terminal on |
|
| the module. If no spark the "I" terminal module must be replaced. If |
|
| there is a spark the "I" terminal is fine. Inspect pilot assembly for a |
|
| shorted wire or cracked insulator around the electrode. |
| - Igniter Spark gap is | - spark gap of the ignitor to the pilot should be .17" tor 1/8" |
| incorrect |
|
- Out of propane gas.
- fill the tank.
Pilot will not light. Makes no noise with no spark at pilot burner
- | Transformer | Verify the transformer is installed and plugged into the module. Check | |
|
| voltage of the transformer under load at the spade connections on | |
|
| the module with the ON/OFF switch in the "ON" position. Acceptable | |
|
| readings of a good transformer are between 3.2 and 2.8 volts A.C. | |
- | A shorted or loose | Remove and reinstall the wiring harness that plugs into the module. | |
| Connection | Remove and verify continuity of each wire in wiring harness. | |
- Improper switch wiring | Troubleshoot the system with the simplest ON/OFF switch | ||
- Module is not grounded | Verify the value and pilot assemblies are properly grounded to the | ||
|
| metal chassis of the fireplace or log set. | |
- Faulty module | Turn the ON/OFF switch to the "OFF" position. Remove the igniter |
|
wire "I" from the module. Place the ON/OFF switch to the "ON" posi- tion. Hold a grounded wire about 3/16" away from the "I" terminal on the module. If no spark the "I" terminal module must be replaced. If there is a spark the "I" terminal is fine. Inspect pilot assembly for a shorted wire or cracked insulator around the electrode.
Pilot sparks but will not light | - Gas supply | Verify that the incoming gas line ball valve is "Open". Verify that the | |||||||
|
|
|
|
|
| inlet pressure reading is within acceptable limits, inlet pressures must | |||
|
|
|
|
|
| not exceed 14" W.C. | |||
|
|
|
|
| - Module is not grounded | Verify the value and pilot assemblies are properly grounded to the | |||
|
|
|
|
|
| metal chassis of the fireplace or log set. | |||
|
|
|
|
|
|
|
|
|
|
Continues to sparks | - Short or loose | Verify all conncetions. Verify the connections from the pilot assembly | |||||||
and pilot lights, but | connection in sensor rod | are tight; also verify these connections are not grounding out to any | |||||||
main burner will not |
| metal. | |||||||
light |
|
| - Poor flame rectification | Verify the flame is engulfing the sensor rod. This will increase the |
| ||||
|
|
|
|
| or contaminated | flame rectification. Verify correct pilot orfice is installed and inlet gas | |||
|
|
|
|
| sensor rod | specifications to manual. (Remember, the flame carries the rectifica- | |||
|
|
|
|
|
| tion current, not the gas. If the flame lifts from pilot hood, the curcuit | |||
|
|
|
|
|
| is broken. A wrong orfice or too high of an inlet pressure can cause | |||
|
|
|
|
|
| the pilot flame to lift.) The sensor rod may need cleaning. | |||
|
|
|
|
|
|
|
|
| |
|
|
|
|
| - Poor grounding between | Verify that the wire harness is firmly connected to module | |||
|
|
|
|
| pilot assembly and |
|
|
|
|
|
|
|
|
| gas valve |
|
|
|
|
|
|
|
|
| - Damaged pilot or dirty | Verify that the ceramic insulator around the sensor rod is not cracked, |
| ||
|
|
|
|
| sensor rod | damaged, or loose. Verify the connection from the sensor rod to the | |||
|
|
|
|
|
| sensor wire. Clean sensor rod wih an enery cloth to remove any | |||
|
|
|
|
|
| contamination that may have accumulated on the sensor rod. Verify | |||
|
|
|
|
|
| continuity with multimeter with olms set at the lowest range. |
