Hi have a question,our dometic air doesn't blow cold air.The compressor and fan work.Inquired about recharging Freon and was told it can't be done, need new unit.

I know the feeling. Some people are actually putting residential window units in the side of rigs. Not sure how that works though.

Hi Elvira,
I am sorry to hear of your A/C issue and can only ask if you have checked with a reputable RV A/C technician to see if there is another problem... something dirty, loose wire, bad thermostat, coils plugged, etc., that may be causing the "Fail to Cool" issue??

Some years ago, I bought a current edition (at that time) of Woodall's RV Owner's Handbook and though it is not a replacement for a good mechanic and may not cover everyone's models, it is a very good reference book.

I have a 2 inch binder that is my "Trailer Book" with about everything I have on my trailer from axles and brakes to the TV and radio antennas, and has become a great reference book for me. Building your own personal reference book for YOUR TRAILER will be an asset to you and the next owner if you ever decide to sell... If you don't have this already, start by collecting the appliance manuals (A/C, heater, water heater, stove, refrigerator, vent fans, pump, batteries, smoke and CO2 alarms, electrical converter and battery charger, holding tanks and wall panel, etc.), along with their respective maintenance sections, and get/make a manual for your trailer; keep these current with changes and upgrades you make. This will become invaluable as time goes on, unless of course, one is blessed with a bottomless wallet.

Good luck and I hope your A/C issue is something simple and can be fixed

I hope to meet you sometime around a campfire...

Yes Ma'm you did, I just had to toss my 2 pennies in the pot... Probably my best reference data anymore is my Trailer Book/Binder...

I have started a new section with pics of critical assemblies, valve positions, etc. in the trailer... The guys worked on the trailer this last winter/spring and I couldn't find the the fresh water tank drain... it was there, but during the repairs, the valve became obscured... I am going to pull the tank during winterizing this fall and replace the valve and location!...
There is a tangle of hoses and valves under the "carpet", so to speak, and this pic shows the tight space and the cheap plastic valve is way down on the other side of the tank under hoses, stuffed between the pump and tank... there is no way to even see it... I am considering building a "Valve Panel", if I can without pulling the trailer apart...

I'm thinking you intend to keep your trailer for a long time, right. We were happy that we got all of the individual manuals with our FF and grateful though we never needed to fix anything happily. We passed them on to the new owner.

John C ~ like you I have all the manuals for my unit, originals from the factory plus other tid bits I've added here and there.

I like to know how things work and why and how things are put together so they are good reading material and of assistance if/when needed.

And I must add, invaluable when one makes alterations too!

I have also made a book of information about everything in and on the RV. I also have downloaded all the information and stored it electronically on a thumb drive. The big heavy book stays at home and the thumb drive travels with us along with the laptop.
