Rear LP furnace wont light

[sfedeli3]

Ed, Soak the screws and let stand overnight. They will need to soak. 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.

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.
