Dometic AC potential issues
SEE UPDATE ON PAGE 2 My Dometic AC froze up while camping last weekend. I would let it thaw and it seemed to work for awhile and then freeze up again. When we got it to the storage yard I took ...

1. The freeze Sensor not connected. WHY would you install a new one? Why not just install the old one?
2. They are sealed systems. IF you had a leaker, then ALL the coolant would have been gone by now. They only hold a 16 ozs of coolant.
3. Water Coming OFF the roof indicates the Unit is doing its job.
4. Your brother and you have no way to tell if the compressor is "going" bad:B FYI, your compressor is not going bad.
5. How hot is it and how big is your RV? Doug
OP here,
The end of the sensor did not have the flat blade attached so it broke off or whatever. To be safe it wasn't an expensive part so I replaced it.
I stated that I had no clue about the compressor. Was hoping for a little feedback if there was any simple way to determine any issue with it.
It was in the mid 70's now 80 at noon and the AC has not shut off at all.
It is a 32 foot 5th wheel and the AC is a 15,000 BTU unit.
A 15k AC in a 32 foot RV will NOT cool the RV. Especially if you have slide out/s. Period. The max size for a ducted 15k is about 27 feet. Don't listen to responders that state they have a over 27 foot that does cool with 1 AC. I am giving you 40 years experience with RV's and sizing of Roof AC units. You need to have a operational check of that AC unit. You need
1. The compressor amp draw at ambient correct temp
2. The Temp Differential between the closest cold air outlet and the return air filter. The temp Diff will be 19 to 22 degrees. IE -- 82 hot in 62 cold out would be very good. Doug
My Atwood did a fine job in August of 2017 when we could only get a 30A site for the eclipse. 95, humid as heck and no shade in the middle of the day. It worked hard, but kept it in the 70s.
