Need some help getting the "frig" to work on lp gas.

It works great on electric, however when it switches to LP it will fire up and only run for about 2 minutes. After that the frig alarm starts beeping indicating it not running.

I checked outside and can't seem to find anything wrong. I have reset it several times and each time after about two minutes the alarm goes off.

I think it keeps running out of LP but don't know why. Yes, I have a full tank of LP.

Thanks for any help.

In order for the LP to flow, both the valve and your LP gas detector/emergency shutoff must be OK-to-go and for our frig, it seems to automatically change to electric if we are plugged in.

As Bud mentioned, both valves have to be on. Also, the reefer consumes very little gas, so the lines have to be purged of air by lighting off one of the stove burners.

The propane line was clogged on mine(cleaned), purged line ( pilot on cooktop has to be lit), had to clean out rear of refg., after all this I had to replace reg. on 40 pound LP tank. Great fun tracking all this down.

Mine won't run on propane if I'm plugged in to shore power or have the generator running. Checked with refrigerator people and they said that was the way it was designed.

Disconnect the refer from AC power by unplugging it in the back. While standing there you should hear a click and then a series rapid clicks and them you should hear the burner light. If the clicks continue after the burner is lit, the board is not "Seeing" the flame and cuts power to the gas valve. Two minutes seems like a long to me but that may mean that you have another issue. Possible causes, the flame sensor is bad, the board is bad or the burner is full of rust from the flue and needs to be blown or vacuumed out. Of course the connecting wiring needs to be in good shape too. To check the gas pressure connect a manometer to the pressure port on the side of the valve and switch the refer on LP. It should read between 11.5 & 13.5 inches water column.

Billy,

Do I have to move the frig. or are you talking about the outside access panel.
My frig. will work (or use to) on LP gas even when hooked up to shore power or when running the generator. It has a mode selection button as follows 1) ac mode, 2) lp mode, 3) ac auto, 4)lp auto. With the 3 or 4 selected it will go from lp to ac or ac to lp. So if your hook to shore and disconnect it will auto. go to lp. If your on lp and hook up to shore it will auto. go to lp.

When I press lp I can hear it ignite and when I went outside and felt the exhaust area it was getting hot and then shuts off.
I have not had the time to pull it apart at the outside access panel.
I did turn off the shore power and it will only click on for what seems like about two minutes and then shuts down.
I will be taking all the suggestions and go thru it one by one.
I can light all the burners on the kitchen stove and that does not affect the frig. at all.

All things that need access are inside the outside compartment.

Your symptoms point to a bad thermocouple, which as Billy mentioned, tells the control board (which also may be defective) the flame is burning, and it's OK to keep supplying gas.

It could also be a bad solenoid valve or an obstruction in the gas supply line, but both are less likely.

Most RV dealers have an instrument to test control boards, so you can pull it and take, or drive to the shop and have it tested in place.

Jim, I don't know if you have "a guy" for testing these types of things, but there's new place just North of North Port called American RV Technology. I stopped and met the owner, Frederick Lawrence, and he seems like he knows a ton about RV's. If you're up that way stop in and talk to him. He's from New York but looks and sounds kind of Jamaican and he likes to talk RV's.
Go through N.Port and just past WMS but before the Myakka, where the old 84 Lumber used to be. Look for the Regency beside the building. It's his.

If nothing else, he has good taste!

Thanks for the info.
I think I met Frederick once at Charlotte Harbor RV Service.

I still haven't had time to get into the access panel, however I did notice the last time I checked it the vent seemed to get very hot when on that LP mode before it shut off.
