I replaced both of my fan motors not because they failed but the bearings were worn and they made a bunch of racket. I payed less than $100 bucks for each of them including shipping and the run cap. Made by Fasco, D1092A I think.

Thermistors operate on very low voltage - it's very important to have a good connection. I'd look at where it connects to your control board.

I have checked connection to the controller in the ceiling. It all seems to be tight connections. May have to call Dometic back and see what they have to say. Just hit me, I might switch control boxes and see what happens. ??

Having replaced two out of three of my original Dometics in 3 years, I am resigned to the fact that I will be shelling out for another one soon.
Trouble is you can't replace a Penguin II with anything else, unless you change the plenum, which is more work than I care to undertake.
I also have a Dometic outside cooler, which is two years old, already the digital readout is gone, and I'm sure it's reaching the end of it's life, now that the warranty is up. :rolleyes:

I'm probably going to be replacing my A/C units on my '94 Georgie Boy in the near future. You say changing the plenum is a lot of trouble. Does this apply to the older Penguin units as well or just the newer Penguin II's?

How did you manage to lift those 135# units up to the roof??

I used a tractor with a front loader

I want to replace my front roof A/C with a Coleman Mack Air 15K unit. Currently it has the original Dometic Penguin. It's a '94 Georgie Boy Cruise Air, 34' on a Spartan chassis. I know I will need the inside ceiling unit and wall mount thermostat. Can anyone tell me if the through-the-roof frame size is the same? Also, will the Coleman thermostat be compatible with with the existing gas furnace? How many wires does the Coleman thermostat require?

I've had campers with A/C units for 35 years and have not had one fail that I was unable to easily repair yet. If you're replacing them something else is going on as has been suggested by other posters.

I would go to great lengths to avoid the newer R410 refrigerant units.

Radiators have coolant, A/C units have refrigerant.:facepalm:
