Rear LP furnace wont light

[ronmarabito2002]

Ed: Was the igniter actually sparking? The funaces also have a sail switch
that must function in order for the gas valve to open. When the fan starts
blowing, it causes the sail to move and open the switch. Check for continuity
through the switch.

Carefully remove the ignitor assembly (thing with the wires) by removing the two
hex-head screws and see if the ignitor is grounded out or filthy. Be gentle with
the gasket- they can crumble easily. Clean the ends with some emery paper.
Usually, the middle pin is a ground. The one on the left is the ignitor and the
other one goes to the thermocouple. The ignitor should be 1/8" from the center
ground pin and the Thermocouple should be 1/4 from it. When you start the unit,
a fan should come on and then a few seconds later, you should be hearing an
audible "click" from the propane solenoid opening. If you are not getting the
click, you'll need to pull out the unit and check the sail switch just behind
the blower fan. Sometimes, they can accumulate dust and will not open entirely.

behind that is the igniter. Open it and check for ash bridging the gap. The
furnace produces flakes of ash and they can get in the way. Vacumn out the area
and then try it. If you still have no spark, the gap between the electrode and
the gas burner might be too great. I'm going to bet you have ash in the way.

comes on but I dont hear any sparking from the igniter,therefore it never lights
the gas. Gas valve is turned to on, all other heaters work ,also cooktop works.
Dash sw(lp heat) is on.
