Rear LP furnace wont light

Rear LP furnace wont light
My rear LP furnace, under all the dresser drawers wont light. Blower 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.
My question is 'how do you remove it to check it out(89 SP36)?Have any of you
removed this furnace(NT-16SW).How do get to the elec. connectionin the rear?
Any advice and or experiences would be welcomed...


Thanks

Ed: There is a little inspection window that can be opened. Right 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.

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.

Dan Sunderland showed me a can of penetrating oil that he claimed was better then PB blaster. I tried some on my 28 year old pop-off valve on my hot water heater. Sure enough, it works. It is called Kano- Aero-kroil www.kanolabs.com Of course I would LIKE to have a financial interest in this company. Gotta get back to work demolishing an Lxi in my front yard~

Thanks, Ernie and Shane for your help. I did get the screws out so I pulled out
the ignitor and it looked brand new. Now rust or ashes. Now I'm atempting to
remove the furnace so I can maybe see the problem. Still have heard from anybody
that has removed one. Am having to remove vent to bathroom through cabinent.

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.

Rear LP furnace wont light

Looks like I responded to the wrong email!

Ed,

I have “overhauled” all three of the furnaces in our 82
so if you need any help or information give me a call. I can’t tell
you how to get the furnace our of a SP but can say to look real
carefully. I started to tale the cabinet apart to remove one of ours only
to discover that all the parts around the furnace was held in place by magnets.
I all of ours the case stayed in place. There were two screws
in front, then I had to remove the gas line and the screw through the exhaust
and the “works” slid out.
