Well I had some time on my hands today so I decided to research some more info on my frig. I found that there is an item called a thermister located on the cooling fin in the frig. So I first took compressed air and blew out the flue and made sure that it would ignite on both propane or 110v. then I increased cooling on the front control panel and then slid the thermister up on the cooling fin. And wala its working. I have it now plugged in and will monitor. This might have saved me some money and was a simple adjustment.

The thermistor adjustment will only change cooling a couple of degrees.

Brett if your correct and I am sure you are then I can only assume that my flue was full of rust which prevented the the frig from working.

Yes, cleaning the burner tube and flue can have a much more significant impact on cooling.

So, if the coolant has not leaked out (ammonia smell) there are some "tune-up" thing you can do rather inexpensively. One that is often neglected is to check propane PSI. If lower than 11 column inches of water, burner performance is reduced.  New propane regulators are under $30 and if still in good condition, many can be adjusted.

The other thing that I have found is that many do not give the burner area a regular check up. I have found piles of rust from vent under the burner and some inside the tube so much so that the right type of flame was not being achieved. Easy to take apart and blow out. The edges of metal flame grooves in time get " carboned up" and so the shape of flame is rough. Easy check and repair and does make the unit run correctly.
