50W415-0788 / B / 11.03.1013.0 TROUBLE SHOOTINGSYMPTOM PROBLEM TEST SOLUTIONPilot will not light.Makes noise withno spark at pilotburner.Wiring. - Verify the wire for the sensor and the wire for theignitor are connected to the correct terminals (notreversed) on the module. NOTE: Sensor has 3/16”connection and ignitor has 1/8” connection.Loose connection. - Verify no loose connections, electrical shorts in thewiring or ground out to any metal object.Module. - Turn the ON/OFF switch to the “OFF” position.Remove the igniter wire from the module. Placethe ON/OFF switch to the “ON” position. Hold agrounded wire about 3/16” away from the ignitor(spark) terminal on the module. If no spark theignitor terminal module must be replaced. If thereis a spark the ignitor terminal is fine. Inspect pilotassembly for a shorted wire or cracked insulatoraround the electrode.Igniter Spark gap isincorrect.- Spark gap of the ignitor to the pilot should be 1/8”.Transformer. - Verify the transformer is installed and plugged intothe module. Check voltage of the transformer underload at the spade connections on the module withthe ON/OFF switch in the “ON” position. Acceptablereadings of a good transformer are between 6.2 and7.0 volts A.C.Battery backup (if poweris off)- Check batteries.A shorted or looseConnection.- Remove and reinstall the wiring harness that plugsinto the module. Remove and verify continuity ofeach wire in wiring harness.Improper switch wiring. - Troubleshoot the system with the simplest ON/OFFswitch.Module is not grounded. - Verify the valve and pilot assemblies are properlygrounded to the metal chassis of the appliance or log set.Pilot sparks butwill not light.Gas supply. - Verify that the incoming gas line ball valve is“Open”. Verify that the inlet pressure reading iswithin acceptable limits, inlet pressures must notexceed 14” W.C.Out of propane gas. - Fill the tank.SENSORIGNITOR(SPARK)PILOT TUBE42.7! WARNINGALWAYS LIGHT THE PILOT WHETHER FOR THE FIRST TIME OR IF THE GAS SUPPLY HAS RAN OUT,WITH THE GLASS DOOR OPEN OR REMOVED.TURN OFF THE GAS AND ELECTRICAL POWER BEFORE SERVICING THE APPLIANCE.APPLIANCE MAY BE HOT, DO NOT SERVICE UNTIL APPLIANCE HAS COOLED.DO NOT USE ABRASIVE CLEANERS.
