F53 Ford AC trouble

[seniorgear]

I can't seem to figure out why the clutch on the AC compressor is not engaging. I have looked for a fuse but no luck. Is there a fuse link on the wire leading to the clutch ? It was operating earlier this year.
This a 1998 model Georgie Boy 35' Class A coach. Can anyone help ?

If you are low on feon or have a bad low presssure switch then the pressure switch will not allow the clutch to engage. Look on the freon lines for a pressure switch with a plug with two wires attached to it. Pull the plug, jumper the two wires and see if the clutch engages. If it does, take it to a shop and have the A/C serviced.

Her is what I did to mine.
I have two AC's on top of my Pace. One worked fine, the other just blew hot air. In my coach on the bedroom wall there is the ''control center'' thingie. It is a brown box with slides and selector switches that work each AC.
One .....I turned off my electircity and took my house batteries lose. I carefully removed this brown box and unplugged the wires (lable wires) from the back being careful not to let them fall in the wall cavity.
I took the thingie to the dining room table and opened a beer and took a sip
I always carry ''contact cleaner and WD40'' with me ..... (I took another sip of beer)
I took the contact cleaner and carefully sprayed it on the ''slider contacts'' with the unit facing down on the table (on a paper towell, being careful not to get any cleaner in my beer)
I did both ''sliders'' and both ''selector switches'' while I had the unit out.
Engineering note...... When you put the contact cleaner on the ''slides'' you need to wiggle the slides up and down to ''clean the contacts''. the sequence is ... SPRAY .... slide up and down,,,,, SPRAY.... slide up and down. repeat about two or three times......

Now you will notice that the ''slides are getting hard to move'' because you have taken away all the lubricant on them.
Now this is the hard part. With the unit laying face down on the paper towell and your beer out of the way, take the WD40 and LIGHTLY SPRAY the sliders. Wiggle the sliders up and down to spread the oil. (they will move easier now)
Let the oil dry till no more ''dripps'' come out of the unit. (take a big sip of beer without spilling any beer in the unit thingie)
Now take the whole mess (including your beer) back to the wall and plug in the wires correctly and re install the unit on the wall.
Turn on the power and re connect the batteries and turn on your AC unit

this fixed mine and I was going to call a fixit man. I saved myself 60 dollars for a service call.

If you use this valuable information you will owe me ten cents and you must pay me the next time you see me...... of course .....if it dont work for you....I NEVER KNEW YOU....


Thank a vet for your freedoms ....

Seajay, he was asking about his dash air... as the ACs on top don't have a clutch

Seniorgear, let me know if that fixed your problem and Thanks for the "Thanks" !

[Seajay]

OOPS.... MY bad for not reading the article completely..
anyhow, If your roof air quits try me ''Fix'' to see it that will work.

Be safe and I will see you at the National in September.....

Lets all thank a vet for our freedoms....

Do you happen to know where the low pressure is located ? This is a F53 Ford.

The switch will be located on one of the feon lines. Just follow the wires from the compressor to the switch, or look for a switch with two wires coming off of the freon lines.
