I did consider the cooling unit change out.
A little background- I am for all practical purposes full-timing is this trailer, following the work. (last 7 years) I generally work six days a week (6 x 12's) and sometimes a half day on Sunday. I needed to resolve this quickly that is why I went with the local dealers first. I had hoped that CW might have my model in their store, so a phone call was in order. The store was 45 minutes from the work site I was at.
If they had responded I would have purchased and then swapped out that evening. As it is now I should be swapping out tomorrow night. (I have to be in South Texas today for the day).
The new one should be cool enough by Friday evening to allow me to put some groceries in it. I am not a fan of eating out very much. I did do the diagnostic checks per the manual and voltages, fuses, and resistance readings were within parameters. Heck the coil is hot at the top and the boiler insulation is quite warm to the touch. I had hoped the thermister was bad. No such luck. Everything checks out so it should in theory be working. I will at least have a unit that has some sort of mfg. warranty for a bit.
RV has been through two hurricanes and two blizzards in the last seven years besides the normal ND and Chicago winter. Preceded by Gulf Coast summers and falls (heat and hurricanes) and also followed with South Texas summers. The rig has held up well considering the abuse it has seen.
