FIXED: dometic fridge question

Hello all, I am hoping this is the proper area for my question. I have a dometic rm2652 in a 1999 sandpiper 28?', it was working great, and one day the check light came on while running on gas, so I fired up the genny and it works on a/c.

I called the mobile repair guy and he charged me $200 to tell me the "lower control board" was malfunctioning. I am a euro mechanic and I'm very familiar with wiring diagrams unfortunately, so I bought a "replacement board" which cost me $100 shipped, installed it, and it did not fix the problem. When I turn it on, either on gas or auto, the check light turns on for a split second. When its on gas, the fridge turns on for 5 minutes and then the check light comes on. Turn it to auto, and the a/c works flawless. ??...

The other possibility I thought of was some kind of problem with gasflow. The reason I say that is because the stove has a "high flow" burner on the front, and ever since the fridge had a problem, the flow on the stove burners is noticably lower.. the big burner is less than half the size it used to be... and the smaller ones are TINY...

Shortly before I had this problem, I bought an 8000-13000peak generator, troy built. Before that I was running a 3500w 4000wpeak champion. I don't know if that matters, but thought I would mention it.

I have a new regulator to install, not sure if that'll fix it, but ill give it a go.

Any help is greatly appreciated.

By chance are you in an area where it's very cold? There could be moisture that has frozen in the regulator that's restricting the flow of propane. I had this happen when I replaced a bottle on vacation in the south and used it once back up north in colder temperatures. It was bad enough that the regulator would not switch over to my full bottle.

Yes, in fact when the problem started, I had switched tamks in the rain, which is why I got a new regulator... I'm gonna throw the regulator on, and see if that fixes it. Thx bro!

Also opd valve might have popped .

Turn tank valve off wait a few the slowly turn it back on.

If to much gas flows the valve will close sensing a leak .
To reset do above for mentioned tank reset.

I don't think this is related to your problems, but I think some of the RM2652s were on the Dometic recall list. Check that out here: Dometic Recall Information - Dometic

The recall was supposedly already done, according to the guy that came up to look at it... how would I know if the recall was handled?

Check out the Dometic website......I think they mark it on the burner shield, or something like that.

Try blowing out the
Gas lines sometimes insects get in there and block the gas flow. Use to happen to mine all the time

Low flame might be oil in propane lines. disconnect lines and blow out the oil. Always works for me.

Drc and camper 99, did you also have a problem with the gas side of the fridge? Or was it just your cooktop?
