Some RV shops can test the circuit board. Many just want to replace them.
The flue can be cleaned from the bottom some what.
Remove cover from flame area,
Use a flexible wire and slide it up into the flue. You normally would only have to go three or four inches, until your wire hits the baffle.
Rattle the baffle good. You may see rust and carbon fall into flame area. Vacuum or blow it out good.
Ventilation causes many problems with cooling. Check to see how much distance is between the cooling unit and exterior wall just above the exterior access. It should be only about 3/4 to 1 inch. Any more will allow most of the air to bypass flowing through cooling unit. This can be closed up using insulating board strip. I used Liquid nails type stuff to hold it in place.
Another ventilation area that causes air to slow down is at the top of the refer. The ledge made by the refer stops or slows down the hot air from getting out of the top vent. I used some flashing material bent into a curve to get air moving better. This requires the removal of the refer to do it in the best manner.
Dinosaurelectronics.com owner can tell you the best way to test the thermistor. He is very nice. If you decide on new circuit board, go with the Dinosaur board. It comes with a thermistor adjustment circuit.
edit: saw last post. Sounds like ventilation, thermistor or circuit board. Start easy check ventilation.
