Perhaps we would be wise to get a shop to look at it? Maybe it has leaked some ammonia somehow? Still planning on getting in a few more camping days so I hope it doesn't crap out before then.

Thanks for all the help!
I've seen(smelled) the aftermath of a ammonia leak, there's no mistaking it, worse than propane/LP gas tracer. Good luck.....

Gil,

If it was coolant; it would not work on anything.

The hissing sound may have been unrelated to the fridge.
Perhaps a capcitor in the converter (if it is under the fridge) gave up the ghost? How are the lights? Are they getting dimmer? Check the voltage on the battery when the camper is plugged in. 13 volts or more? If not your converter let go.

Look for a yellow stain on the back of the refrig around the flue pipe. Also a strong smell of ammonia inside the freezer. If neither then there is no leak. The hiss sound you hear may come from the door seals Some times they will hiss when closing as they are just sealing.air is just escaping from the seals Hope this helps

Argh.....

This morning I went out to the trailer to get the last few cans of pop from the fridge, and lo and behold, it has quit working again.

Herk, all you suggested is fine. As you say, if it works on propane, it can't be the refrigerant system.

BillT, I will look for yellow stains. The seals have never made funny noises when I have been around the fridge. Sometimes they stick of dourse and can make a funny noise when you pull hard to break the seal. Perhaps that is what DW heard, I dunno.

Worst thing is, this all happened a couple of weeks after the warranty expired. May very well have to pay someone to fix it if I can't find anything.

It started not working at all, then worked then not, can't be fuse or power supply but could very well be the electronic board which contols both gas and electric on off via thermostat, just an idea.

VinceU, perhaps that is it.

Isn't that one of those things that is really expensive to replace? Intermittent faults can be so hard to diagnose, but maybe in these fridges, if everything else seems okay, the only thing left to cause the problem is the board?

This sounds more and more like the control board.

You can get it repaired at a Dometic Repair Center or fix it yourself.

The board is only less than 6 x6 and not that much on it, however it is Dometic! But like you said, ya can't leave home without it! Meanwhile it could be a loose connection somewhere but less likely, not a short but something loose. Lou has given you some good TS help if you feel like following it first. Just acting like a electronic intermittent failure, prob on the thermostat side

We had a similar issue and it ended up being the ventilation was getting blocked by some stuff that was left over from assembly. Worked fine, then would not cool, but would turn on using both AC and propane. Luckily, we were able to use the outside fridge when we found out it had quit cooling. You can pull the fridge out a bit and see if there's anything blocking it's ventilation up top, that's where our issue was. Dealer found it for us.
