T-2499 refridgerator

We just bought a 2005 Solaris Sunline. We were told that the refridgerator runs on electricty and can run on propane gas but is not hooked up. Does anyone know anything about this and is it an easy fix?

I can't understand why it's not "hooked up" It needs a battery connection to work and also a gas line but there would be no reason to "unhook" it. Does it work OK plugged in?

Pull the outside vent cover for the backside of the fridge.

There's a copper pipe that is supposed to be connected to the fridge. If it's disconnected, it will be real obvious. That's the propane gas line.

There's a 110vac outlet there also and the power cord from the fridge should be plugged into it.

Lastly, there are a couple of colored wired fastened to a small terminal strip on the back of the fridge. They should also be pretty obvious.

If all three above are connected, the propane side of your fridge is not "disconnected."

Obviously, to run the fridge on propane, you need propane in the tanks and at least one of the tanks turned on.

It also needs 12vdc to run the electronic brain of the fridge regardless of gas or 110vac operation. It can only get that if the battery is in place, charged, and turned on to the trailer. You can force the fridge to gas when you're shore lined to 110vac, but the convertor needs to be on to provide 12vdc.

Your fridge is probably a Dometic. There are manuals in the FILES area. Generally multiple model numbers are covered in one manual. You can also find the manual on Dometic's website.

Thank you for your great response! We just purchased the trailer from the second owner. He never looked into it from what the first owner told him, and he always went to camp grounds and used electric for the fridge. We will definetly check this out. We are picking up the trailer tomorrow if weather permits.

It is possible it does not work on gas but there can be several reasons for that. If it cools on AC there probably is nothing wrong with the fridge it's self more so the controller. I would hope the line is plugged other wise it might go boom if the range works I guessing it is. It would be a simple task to reconnect it and see what happens (after a good check for leaks first).

These pics are from a 2004 T2499, your 2005 should look the same.

The comment about the gas being "unhooked" does not add up. Why would they unhook it, meaning physically unhooking it???

In these case pictures go a long way to help show what you have.

There was a recall on the Dometic fridges and you can see the added parts if it was done. If it was not done, it can still be done and is free from any Dometic service place or RV dealer who repairs Dometic fridges.

The pic shows the metal shields of the recall once the white outside cover is removed



This pic has the metal shield removed and you can see the copper gas line


This pic is a close up of the gas valve. There is a actual shut off valve as part of the gas valve. It has a screw driver slot just after the black solenoid part of the valve that you can turn and shut off the gas. The slot straight up is off, the slot horizontal is on.


The 1st owner may have turned that screw to shut off the gas operation. Why? real good question, but that may be what transpired. There may be some other issue with the gas part of the fridge that does not work, but it is all fixable. If the copper tube is physically unhooked, it must be capped off or properly plugged.

Did they use any of the other gas appliances? Stove, hot water heater, the furnace? If they did and they all work, then hopefully someone did not leave an open gas line at the fridge connection. Odds at least exist they did not do that as a leak that big the other appliances would not work, but for sure check it out.

Hope this helps and good luck with your new camper.

John

Never found any mention of it in the manuals, online, etc.

The device is a thermal switch that cuts out at a preset temp so I'm guessing it just came with the boiler assembly as a generic part one size fits all. Your's would have no need for it as it is mechanically controlled. I like the "dumb" fridge it does not need a battery to operate pretty simple stuff low parts count.

Hi Wesley,

As Mainah stated, that is a thermal disk switch with a reset button on it. Dometic had a recall on certain model fridges. When I took the camper in for the recall, they installed that thermal switch, a thermal fuse on the back side of the boiler area and a heat shield.

The thermal switch is there to shut down the gas valve if the boiler tube gets too hot. The recall surrounded that in some cases the electric heating element could overheat the boiler and in time, crack the welds causing an an internal leak. All the coolant would leak out and the electric element could would continue to heat and never shut off. In some cases the boiler tube got so hot it started a fire to surrounding combustible material. The same problem could happen on gas, but it seemed worse when they had a very high heat electric probe. Any of the new fridges come with this.

In your case, it sounds like maybe someone did the recall. You might have the heat shields, the thermal switch and the thermal fuse. Just you do not have an electric gas valve to shut down but the heat shield make give some help.
