Strange Norcold problem

[indie52]

We have a 1995 Winnebago Brave and have a strange problem with the fridge when it is running on propane . We went on a 6 week 13000K trip in June of this year and the fridge worked great all the time , except once in awhile the pilot would go out at night. If you turn it off and back to auto or lg it would fire right up and usually run the rest of the night with no problems. It only happens at night , it has never gone out during the day.
I'm not sure of the model of fridge it has the automatic igniter and switches to propane when I disconnect from power every time.
I think it is related to battery voltage we have a solar panel on the rig and have no trouble with the fridge during the day the while boondocking.
Even at night I have never seen the battery voltage drop below 12.4

Ideas ?

Ours did that just before the ignitor circuit failed completely - apparently when the thermostat shuts down the flame, it doesn't always re-light once the refrigerator needs more cooling.

We got a Dinosaur replacement for ours, since the ignitor board was separate from the main board...

You mention the Pilot and said it has an "auto ignightor"

It has one or the other, never both.. I think by "Pilot" you mean Main Burner, it is not much different than an old time furnace pilot light.

There are two or three things that can cause the situtation you describe which I can think of.. And I have seen this on furnaces, twice.

The suggestion that lower battery voltage may be part of the issue is a good one. As the battery voltage drops the spark voltage also drops, and if it's too low it can not jump the gap.. And thus no ignition.

However if the electrodes are not properly spaced.. Then the "Need" may be greater, voltage wise.. This is the problem I have seen with two furnaces.. An oil fired one in my parent's last house and my own RV unit.. Both the gap was way bigger (2-4 times) what it should have been. Adjustment fixed.

The other is dirty electrodes or dirty burner orafice...

In both of these, Routine maintenance should fix it.

thanks for the replies I am going to check out both ideas . I'm sure the answer is there.

you are right, I meant the main burner would go out and not relight
