Burner tube assy. older Norcold Frig

[pbitschura]

Next project; disassemble and clean the burner tube on my Norcold Frig. It looks like two nuts and it should slide out.Is there some adjustment required to align the igniter and tube beyond comon sense? Recent events lead me to believe a cleaning is in order. It's a 1988 C.What say you about cleaning the flue? Any pointers would be useful.

When I replaced my old rusted out burner with the new style flare fitting I used the existing Al gas line and just flared the end. You can see from the above picture the "S" tube has plenty of length to it. I used a tube cutter and flare die both of which I had already. Chris Bryant's advise was very helpful on this project.

In my case, the length isn't there to use existing aluminum tube. So it will be copper.

This looks doable. I assume flared ends and friction couplings?

Yeah. I had to buy a new flaring tool. I destroyed my last one making rigging for my Daysailor.

I had to make a new gas pipe from copper tubing. About $8 in tubing and fittings at Aubuchon hardware.

Why not do a REAL burner area tune-up. A lot better than just using compressed air.

Most refrigerator owners manuals on older models covered what needs to be done. Suspect many newer ones just suggest taking it to a dealer. But you should be able to find instructions, or ask and we can post them.

If you read back, you will notice disassembly will destroy parts which now must be fabricated, and, in the end, it will be a dealer repair and upgrade on an '88 frig.

I feel your pain... My fridge is a 1999 old school push to spark unit. Works great on electric, but every time I go to use it on propane I get a lazy flame and no cooling. I then grab the air hose and give a quick little spurt or two thru the burner and it works perfectly... For a few days... Then I need to shoot it with air again... Seems worse if I drive around then if I stay parked.

Mine is an '88 with electronic spark. It runs beautifully for awhile. It wouldn't relight the other day...it was HOT. After an hour it reset with no problem. Let us see about the next time.

Officially, that old burner and tube are not available or replaceable. The new burner, orifice and tube from any 6 or 8 foot N series should work fine, though all must be replaced if you replace any of it, and the tube will have to be formed to fit.

I may just settle for compressed air and a vacuum.

Be prepared to replace the gas supply pipe. Mine was aluminum and there was no way to loosen the fittings without breaking the tubing.

Good point. Is this still a stock part?

What model fridge??

I'm having trouble reading the tag, corrosion. I'll try to clean and magnify the id plate.
