Subject: House air not cold


New user


Location: Kenosha wi.
I am new to this arena as I have just purchased #290 and have started working on it to get it in proper shap.
The last owner told me a lot of BS about the coach. Now I am trying to figure everything out.
As for the hours air is there any way to Freon to the units below to have them blow cold air.
Any help will be appreciated
Thanks
Steve

Those are old window air conditioners, and take R-22.
Please see - http://www.fmcmotorcoach.com/files/Manual/115_volt_air_cond.PDF
and

and thank Kjetil FMC #477 in Norway for making all that information available to everyone on the NETS !
You can look for "servicing info" on those Duo-Therms on the NETS . . . or call your local AC Man.
Dan Karnarth FMC #850 did "something" with his Duo Therms - http://www.fmcowners.com/mbbs22/photos/photo-thumbnails.asp?albumid...

Perhaps jrobowen FMC #489 in ShoreView MN is nearby and can share the joy of FMC ownership. Look him up in the member Roster.
Lots of INFO here to SEARCH thru . . . maybe even more about the Duo-Therm House AC units.
Welcome !
Press ON ! Lou #120

They are R22, not sure about recharging them or not. You can look up the electrical schematics and trouble shoot from there. They have a time delay relay, so the units need to run a few minutes before the compressor kicks on.

Dan, you forgot to tell him what a PITA they are to do anything with them.

When I first got my coach, the house airs just didn’t do to well. I had them pulled out and the raidiator and condenser blown out to remove accumulated dust and dirt and then they worked great.
