Question about Dometic Rooftop RV Air Conditioner

Open Question

I have a 14 year old Dometic roof a/c, 15K btu that I want to replace on my 1999 Automate 5th wheel. The model # 991731761, serial # 90118855 and Camping World says I keep my inside controls and just replace the condenser, they gave me this model number B59516.xxico Brisk Air. What do I need to do to remove and install new unit?

SOURCE: can you tell me what type of refrigerant is in my

USUALLY its R22. DO NOT USE ANY REFRIGERANT TIL YOU KNOW IT NEEDS IT THOUGH. The plate is usually inside the top cover and you can read it after removing the cover. If its a 110or 220 AC unit Im almost sure its R22. And the weight listed will be the most you should try to put in it. BUT before you do that you have to put on a piercing valve. And the pressures are higher for R22 than R134A. It will ofcourse depend on the outdoor and indoor temps as to what pressures youll be running as well as fan speed. Freezing is 57-58psig on R22 so the pressure after ruinnign 10 to 15 minutes has to be greater than 57 or 58 PSIG. It is normal for some units to run for a while at a lower pressure when 1st started though so dont jump the gun.

SOURCE: My dometic 15k brisk-air cont. cycles on-off

Actually, the dealer is somewhat correct. In the hotter months of the summer, the rooftop units have a tendency to freeze up if not run on high cool due to the lack of air movement across the evaporator. If the unit fines on High/Cool, then run it in that mode but adjust the thermostat.

It should not however, cycle on and off that fast unless you have a bad freeze switch or the incoming AC is too low. If during that 8-10 seconds, the air begins to get cold and then it shuts off, then I would say you have a bad freeze switch. If it runs fine on high, but shuts off in low, I would say it is a lack of air movement.

Hope this helps,

Jeff

SOURCE: I have a Dometic RV airconditioner roof mounted,

Your probably looking at the control module number or something in that area. When you have the ceiling assy off as in cleaning filters, look for a sticker directly on the base of the roof unit. Look all around on that base, even behind wiring harness, you should find a model number and serial number.

No service ports on the unit. It needs to have a service port soldered to it and the system breached before you can check / charge.

Your choices are another Dometic or a Coleman
I prefer the Coleman But the amount of extra cooling you will get by stepping up to a 15K unit will probability not be worth the added cost

Locating owners manual for 5th wheel & factory appliances


You'll probably find that the actual owners manual for the trailer is just a generic one, that covers many trailers in the fleetwood line-up. I'm guessing your worried about the AC, microwave, water heater & fridge. Get make & model numbers off them & I'll see what I can come up with. As far as items in the trailer other than that or questions, feel free to get back to me with any, and I should be able to explain most if not all. I'll also keep my eyes open at work (RV dealership) for a manual of your year.
