Your photo doesn't look like my installation.
The yellow looks like sealant not ammonium from cooling unit

Bingo. The OP needs to remove the Burner cover and look for more yellow residue. If there is Yellow, then the Thermal disc is doing its job. Doug

PS. IF there was NO yellow residue, it is common for the Dometic Thermal disc's to false trip. You then replace the Thermal disc.

I got the burner cover off. I do not see any yellow. The only thing I see is on top of the burner cover and it looks like dirt not yellow.

Here are some pics of an actual failed RM2652 as a comparison

NOTE: This fridge had the recall done to it.

The fridge was removed and underwent dismantling for repair.

Your pics do not show the normal heavy yellow. But, look up where the gas burner and the flame goes up the flue tube to see if there is yellow residue in that area.

Also, your 1999 RM2652 does not appear to have the recall done. I do not see the heat shield of the other thermal fuse. There is still an active recall on this model fridge. Check your fridge serial number in this Dometic recall link. https://www.dometic.com/en-us/outdoor/lp/refrigerator-recall

If yours is in the recall, contact any authorized Dometic repair place; they should be able to do this. Since so much time has passed, they may have to order the recall kit, and it may take a few months to make this if Dometic is out of them.

Hope this helps

Actually I replaced the original fridge years ago but I dont know how to figure out what year that was. This one might need the recall also. I will have to check the serial number. I want to make sure I can get this unit working before having the recall done on it. I will try to look up in the flu and maybe get some pics to see if there is any yellow stuff. Thanks

You replaced the fridge, ok that explains why you have only the one thermal disk switch on the stack and no heat shields and the thermal fuse behind the burner stack.

Yes, just check the serial number.

I have seen just the one thermal disk switches show up on RM2652’s made in 2006. It may have been they tired a partial fix to layer find out they needed the entire recall kit. They extended the recall to include newer models. It is explained in the Dometic link.

Ok well I looked up in the flue with a mirror and I do see some yellow stuff up in there. Not a lot but I also noticed some yellow stuff on side below flue. I took pics the best I could. In the pic you cant tell as yellow as it is in person. So do you think my cooling unit is probably bad? Thanks

My fridge is included in the recall. Why did they not send me something about it? I bought the fridge at Camping world and I know they had all of my information. I guess once I get it working no matter what I have to do to it I can still take it and have recall done on it. Thanks
