Dometic Refrigerator LP Problems

[judithz858]

The refrigerator will not light off when set to gas. If I bypass the circuit board and put 12 volts to the LP Solenoid Valve it will light off. Just as soon as I take the bypass off, the gas turns off. I am getting 12 volts to the circuit board. The fuses as good. This is a Dometic NDR1292-S Refrigerator for LP-Gas and Electric Operation.

IMO i would clean the burner first and check the thermocoupling next insuring the spark gap on the ignitor is correct

I sometimes have trouble with my water heater. I shut off the 120 volt and the 12 volt electric. I pull all the wires and then reconnect them. Do this one at a time. Then the water heater works again till next time it fails about 6 months later. You may only have a poor connection. The circuit board unplugs too. Try it. It can't hurt.

I can think of several possible causes.. Ranging from something simple as a blown fuse to a bad mother board (Control board) to a bad thermocouple inside the Fridge telling it "Cold Enough" to.. Well you get the idea.. You have eliminated the burner, orifice, and solenoid.

Everythign "Up" from there to the house batteries (Well those were eliminated too) is still on the suspect list.

Just ordered a new circuit board. Will let you know how it works after installing it.

I hope you ordered the aftermarket Dinosaur board rather than the OEM. Much better than the OEM.

Yes, we did order the Dinosaur circuit board. Got it today and installed it.
Problem solved. Thanks for the suggestions!

Ah, you did notice "Bad circuit board" was my first guess..

Glad you solved it, and as a bonus you now know the location of every fuse in the system (Something I had to hunt for since some of them are ON said board)

One comment: The drip tube (That ribbed plastic tube with the thing in the end) needs to go out via a vent hole to the outside so it can get the GROUND wet, instead of the wires inside the compartment... Where the dealer left it.... TWICE.
