To Next PageTo Next PageWhat to do if my Lennox Indoor Fireplace burner will not light?
If your Lennox Indoor Fireplace burner will not light, there may be a faulty valve system or a defective 'OFF/ON' wall switch. Disconnect the two black wires from the wire nuts and check for continuity with a multimeter.
Why does my Lennox Indoor Fireplace pilot keep going out?
Frequent pilot/burner outages in your Lennox Indoor Fireplace may occur if the pilot valve flame is too low or too high, causing the pilot safety to drop out. Clean and/or adjust the pilot flame for maximum flame impingement on the thermocouple.
What to do if my Lennox EDV4540CPM-B Indoor Fireplace burners come 'ON' but go 'OFF'?
If the burners on your Lennox Indoor Fireplace turn on but then turn off, check the main burner orifice(s) for any blockage. Clean or replace the orifice if necessary. Also, check the vent system for obstructions.
What to do if pilot burning, but no gas to burner in Lennox EDV4540CPM-B Indoor Fireplace?
If the pilot light is burning but no gas is going to the burner in your Lennox Indoor Fireplace, even with the valve knob and wall switch 'ON', check the wall switch and wires for proper connections. Also, the thermopile may not be generating sufficient millivoltage, so check the thermopile terminals with a millivolt meter. Finally, check the burner orifice for any blockage and remove it.
How to fix Lennox EDV4540CPM-B pilot that won't stay lit?
If the pilot light on your Lennox Indoor Fireplace will not stay lit after following the lighting instructions, the pilot generator thermocouple may be defective. Check the pilot flame impingement on the thermocouple. Clean and/or adjust the pilot for maximum flame impingement on the thermocouple.
How to troubleshoot Lennox EDV4540CPM-B Indoor Fireplace spark ignitor that won't light pilot?
If the spark ignitor on your Lennox Indoor Fireplace will not light the pilot after repeated attempts, check for a spark at the electrode and pilot. If there is no spark and it is properly connected, replace the ignitor. You can also use a match to trigger the ignitor mixture cause recommended and pilot. Check the inlet gas pressure to ensure it is within the limits marked on the rating plate. Finally, clean or replace the pilot orifice if it is plugged.
