Fridge won't stay burning in hot sun

I am going on 21 days now w/ no flame out. I'm now wondering if is really isn't a control board overheating problem that the little fan is maybe helping it. More time, more summer will tell. Trouble is, after this AZ trip, I am not into hot weather camping, so may never know.

This is a normal updraft thru the roof vent, no fans anywhere,.....until today,....I installed one 4" at the bottom of the vent cover. Then, a catastrophic event happened. I had the fan running, and was tightening the last screw, when my screwdriver slipped, went into the fan,....2 blades gone instantly, and very out of balance !!!!@#$%^
Back to the vendor for another fan, 4 bucks down the tubes !
New fan working perfectly, except I picked up the 12 volts off the gas valve, so the fan only runs when the fire is lit. I mite have to change that. The good news is, no F code all day. Bad news, the sun was not as hot as it has been the last 3 days, so while I mite have improved the situation, I won't know till it gets hotter here.
No, no low voltage problems,....14.6 at the gas valve when burning.
Thanks for all the ideas.

While you have found a work around(until the sun gets hot again), you still have a problem. You ONLY need rear fan/s to help with cooling, NOT to keep a refer from completely shutting down. Remember, you have a Flame out code. Doug

For kicks, I would replace the Spark electrode/wire. Cheap and IF the porcelain has microscopic cracks will cause the ac return flame signal to NOT make it to the control board. That is what I would do if you had the unit at our facility. As to HEAT overheating the control board. Except for suburban furnaces built 1976 to 1985, I have NEVER seen heat cause a failure of a control board, especially on a refer. Here in Texas, we experience at least 100 days of 100 plus temps and if heat were a factor on a Refer control board, I would have seen such a failure. Doug
