Ford V10 Chassis Air Conditioner
I have a 2008 Itasca Sunrise, 32H Class A motorhome, Ford V10 Chassis.
The air conditioner has stopped working. Have checking the clutch fuses (are OK) and using pressure gauge on system thinking it may need freon, but pressure levels are high and did not try to add freon. Suggestions?

Take it to someone who works on automotive type A/C. The Ford system is no different than what is in most large Ford trucks. Trying to fix it yourself will cause more damage if you don't know what your doing. Some things are best left to the professionals that know how to repair them.

Search the forum. I seem to recall seeming some posts on a general problem with older Ford A/C systems. More than likely though you will have to take it to someone who can work on Ford trucks due to the weight involved.

Check your low and hi pressure switch. The current goes through these switch to pull the clutch in. And use a volt meter or even a 12 volt test light will help.

True. Some compressors would go out rather quickly. Mine did the first year and Ford replaced it. There was a recall on certain compressor models. The new model of compressor works very very well. My local Ford dealership that handles the F-53 chassis did mine.

Most MH manufacturers use a third party AC system. The only thing supplied by the chassis manufacturer is the compressor. One of the popular suppliers is Evans Tempcon. Contact Winnebago to find who they used. You can download wiring schematics for their system from the Web site.

Most automotive AC compressors are controlled by a low pressure switch. When the system is cold, the pressure is low. Than when it warms up, the switch turns the compressor back on. This keeps the system from freezing. If there is a refrigerant leak, it upsets the balance and the compressor will short cycle or never turn on.
