Cycling A/C Compressor
Any air conditioner experts out there? My dash air was operating just fine until a couple of days ago. Here's the deal. I start the rig and turn on the dash air. I can hear the compressor pull the eng...

OP here. After adding a can with no change I took the rig to a shop. They found a leaking compressor and a bad expansion valve. They replaced the compressor, expansion valve and dryer. They also found contaminants so they flushed the entire system. They just called me to advise that it's done. Anyhow, the service guy advised me:
* that it's blowing at about 53 degrees. This is 10 degrees warmer than what I had before it let me down a few weeks back.
* that they were only able to fill with 3# because the pressure was getting too high. According to my documentation, this is a 5# system.
I don't know what pressures are appropriate. The ambient temp here is about 100 degrees. I'm nervous that this thing will not be fixed right!

I doubt you had 43 degree output at 90 plus temps. Very FEW Class A's get that temp when over 80 degrees ambient. The "norm" is anything below 60 degrees but MOST will get below 55 degrees. Having a full set of gauges would have shown the expansion valve bad. IF your documentation has a sticker that shows 5 lbs of coolant, then IF the pressure did indeed get too "high", then I would suspect the condenser fan system was not functioning correctly. But if it states 5 lbs and they only put 3 in, then it is NOT fully charged. But it depends on what they think is too "high". Ask what that hi pressure was. The hi pressure depending on the ambient will be from 175 to 275(95 degrees)psi. I would call Foretravel with your year and VIN and ask them the correct Lb charge. That will verify if the sticker is correct. Doug
