UPDATE - Dometic #RM2652/2852 "Check" lignt blinking

[B92F]

We bought our 2007 Flagstaff 8524RLS last July and made several weekend trips. The Dometic fridge worked every time, bot on AC and gas. I turned the frig on, on Friday o prep for our first trip of the season. I noticed today that the "check" light was blinking all the time and it had not gotten cold. Gas was turned off at the tank, and the frig was set on auto. Light in the fridge does not come on, but when the door is open the "check" light stays lit and does not blink. Close the door or push the switch lever in, and the blinking resumes.

Disconnected the trailer from shore power and switched over to the gas settings, light continued to blink, and there is no gas getting to the igniter, nor does the sparker seem to function. Checked on line and found a link for a service tips manual on this model put out by Dometic and started checking.

First off let me say that why women do what they do makes more sense to me that electricity and anything powered by it. So following the directions given, I checked the AC at the main terminal block and got a reading of around 29.5 *+/-, using the 200 V~ setting on the meter. Manual said a reading of six volts or less is acceptable. Checked the resistance on the solenoid valve and got a reading of aprox 49 ohms, again with in the tolerance according to what the manual states.

Pulled the cover off of the circuit board and checked the two fuses that are in there, they both appear fine. Not having the understanding/confidence to check anything further on the board this is where I decided to stop.

I am assuming that since the fridge does not cool on AC or gas that the main circuit board may be gone. I'd much rather pay for a replacement, than pay for a new board and a service tech to come to the same conclusion (if the board is the problem).

Any thoughts or ideas would be appreciated. We'll be heading out for a 5 day trip this Wednesday morning and will manage with a cooler unless there is something else I can look at.

Does your furnace make heat?

I say dont laugh because I have missed obvious things like that in the past.

It's parked in the drive way and is level both ways. We filled both tanks up a couple of weeks ago and it's been plugged into shore power all winter. Batteries are good as well. I was hoping it was something obvious, and it still could be, just haven't found it yet.

And also thanks for the quick reply.

To work your refer requires 12VDC and either 120VAC or propane. Turn the propane on at the tanks, turn on stove burners until you get a good solid flame. If propane has been off there can be air inmthe lines. You need to purge the gas lines first.
If you have strong 12VDC, then attempt to start the refer. It may still take several attempts to light it off. Once you know you have good 12VDC and 120VAC you can try switching to electric only. There is a fuse on the main panel that my have blown.

Thanks for the quick reply. I appreciate that.

We did purge the gas lines and check the main fuse as well. Trailer has been plugged into shore power all winter and the batteries are good. I tried every combination of AC, DC and gas with no luck. I did go out and try again to get it started with gas and AC. This time I also turned the climate control switch to ON, and this causes the check light to stay on constant.
