Refrigerator issue - "termo fuse" keeps popping

I have a dometic.

On the back side of the fridge (through outdoor panel) there is a tube that gets hot. It has a electric heating element going into it, and on the bottom is where the gas comes in (for flame).

In the center there is some kind of "fuse", with a small button in the middle of two wires on the sides of it. I think it's some kind of thermo fuse or reset.

My symptoms are that the fridge comes on for a short while (10-15 mins) then all power goes off on the fridge. If I go reset that small button on the "fuse" as mentioned above, the power comes back on.

The pipe the fuse is on is getting hot....

I can only assume it is blowing the fuse for being too hot.

The fridge is not getting cold at all the entire time it is on for 10-15 minutes.

Any pointers or suggestions?
(This is in my bounder)

Thank you!

    It is a safety device.
    Get the system checked out........and stop trying to run that fridge before you have a fire

    Something is causing that thermo to pop.


    If you have a BAD cooling unit, the Thermo will "pop"
    If you have blocked ventilation (your roof vent) the Thermo will pop
    If the Thermo is BAD, it will pop
    When the Thermo pops and continues to pop, the ONLY thing a novice can do is check that roof vent for obstructions. IF NO problems there, you need to get it in to a qualified Refer tech to find out if the CU is bad or the Thermo disc is bad. Doug

    Oh yes to add, the fins inside the fridge are not getting cold, didn't expect the fridge to get that cold that quick. :)

    I think it happened to me, I found the electric heaters were bad. That was a few years ago, so I may be wrong. I just removed my Norcold, and am in the process of installing a residential refrigerator.
