[SIZE=18pt]Our furnace is 7 to 8 years old. We just started to have an occasional issue with the furnace not starting. It would run through the cycle - blower on, click, but no ignition, and the furnace would shut down as it should. Restarting with the thermostat and it would light.[/SIZE]
[SIZE=18pt]Back home, I did a visual inspection. Nothing was obvious until I pulled out the burner and found it rusty with the holes blocked in the area below the ends of the igniter. This looked like a good candidate for causing the issue.[/SIZE]

[SIZE=18pt]After a trip to the online furnace parts store, a package arrived with a new burner, igniter, orifice, and sail switch. The burner assembly is easily removed. Unhook the propane supply line (turn it off at the tank first and be prepared for a bit of propane as the line empties), unclip a couple of wire spade connectors, and 4 sheet metal screws.[/SIZE]
[SIZE=18pt]Out with the old, in with the new.[/SIZE]

[SIZE=18pt]The old igniter had a bit of rust.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]The new igniter came with a new wire (no spade connector) and a felt gasket not present with the original assembly. Also pictured are the old/new orifices.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]The new orifice installed.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]The igniter is installed through the hole above and the two sheet metal screws are the attachment points for the burner.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]The new igniter in place. I positioned the ends of the igniter a quarter inch apart and one eighth of an inch above the burner.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]The burner and gas assembly ready to be reinstalled. The black wire is the new wire from the igniter.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]The burner slides in on the right and the exhaust on the left. I found the screws out of the two holes, bottom right and left, empty with the sheet metal screws rolling about. I replaced them with one size larger (#10) screws and they snugged up nice and tight. The pink rubber cover was removed and the supply line fittings lowered out of the way to easily slide the burner in.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]The sail switch is on the inside of the black half cylinder cover. Remove some wires to get them out of the way and the four screws on the four corners. Rotate the cover around and here's the sail switch.[/SIZE]

[SIZE=18pt]The burner and exhaust in place. The black igniter wire is attached to the new orange wire from the mother board and a wire tie to hold them in place.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]The cover back in place. The wires attached and wire ties in place to keep it all neat. The new thick orange wire (included with the igniter) runs down to and connects with the black wire from the igniter.[/SIZE]
[SIZE=18pt]
[/SIZE]
[SIZE=18pt]We've run it several times, as we would on a trip. It has started up flawlessly every time. It appears to run great. Where shall we go?[/SIZE]
[SIZE=18pt]I thought this would be of interest, including the photos of the various parts I hear people mention here on Wander the West. I expect that most models of these furnaces are all very similar. Hope it helps and best of luck with your repairs and projects.[/SIZE]
