Norcold Ref not working on propane

Ronald Smith · 07-09-2006, 11:49 AM

Have posted similar before but problem slightly different. When on propane my Norcold model 822 will start burning for 30 second then cut off. Replaced spark/sensor wire and cleaned connector but no luck. Flame burns blue but still cuts off propane. I know there are fuzes within the electronics board compartment but have not opened yet. Can a fuze be the problem. Only other thing I can think of is that regulator is not providing proper pressure, in spite of fact that flame appears per the book.
Can anyone help?

Ron,
If it sparks and the gas lights with a good blue flame, but then goes out, you have a board problem and it needs to be replaced. What has happened is the sensing of the flame has gone bad. This uses the same wire as it does for ignition. Once you have a flame, it generates a milli voltage back up the wire and is sense by the board that the gas has ignited. If the sense circuit goes bad, it will lite but then go out as it shuts off the gas valve to prevent any fires or booms. I can't think of the name of the replacement board and where to get it, but someone will pop up with that answer. Good luck.

Before you replace your board try this: turn on several of your stove burners for a few minutes and insure you have a good flow of gas through them. I had a problem with oven going out after a bout 30 seconds and it turned out to be a problem with gas supply. I have an extend-a-stay and it was not completely tight so let some gas through but not enough to sustain a large flame for long. Good luck

This may be of some help. Go to Bryant RV web site and then to the service documents section. Scroll down the page and look for the service manual for the N6xx series fridges. According to the Norcold site the N8xx and N6xx manuals are one in the same. You will find a complete service manual available for download at the Bryant site.

If you find youhave a problem with the lp gas not flowing properly, turn the gas valve off and then slowly open it all the way. If opened too quickly it may think the line has broken and will lock up reducing the output to almost nothing. Good luck, you have been given some good info. Let us know what you find.
