Dometic fridge woes.

Tom M ..actually I did check the filter - it looked brand NEW - because it IS. I looked at before I installed the NEW t'stat. It is located in the inlet of the t'stat. I also looked at the filter in the removed t'stat... didn't look much different from the new. EARNIE1 ... the filter is just a small wad of what looks like cotton (maybe a little larger than a pencil eraser) pushed into the inlet of the t'stat. On this particular fridge the controls and most of the LP plumbing is located on top of the fridge and the fridge sits in a compartment that allows no access to them. The only things accessible from the outside vent is the primary shutoff valve and the burner tube ( along with the orifice, igniter, and thermocouple). This fridge has to be disconnected from the LP supply, unscrewed, then slid foreward into the RV in order to access the filter or most anything else.
