BIGGEST MISCONCEPTION by non professionals. They assume since the lines run 40 foot it takes a LOT more coolant. IT DOES NOT. Like I stated, your system holds no more than 4 lbs usually about 3.5 lbs. Doug (yes, I am a professional). Once you OVERCHARGE a system, That has a high pressure switch, then the compressor will kick out from too high of pressure. Too MUCH coolant is as bad(actually worse) as too LITTLE coolant. Where is this relay you mention? Is it a Bosch or a metal relay? Have you replaced the dryer and the expansion valve? On a system as old as yours, that needs to be done as with no history since you purchased used and so far adding coolant does not get you there, you need to start out at the beginning. Doug
How much for you to come look at it, I'm in waxahachie/ red oak?

IMO You really need to bleed off some of the pressure and jump out the low side switch.
The compressor on my toad was just fine went into a store came out and compressor would not engage jumped around the low pressure switch and worked fine.
The low pressure switch ranged in price from $24 to over $65 so I took it in with me. On the Internet site it showed there were 2 part numbers available for same system and not interchangeable. They had to order and sure enough wrong one took an extra day to fix.
AC was on my Jeep but it looks exactly like the one in the MH.

It is not the running pressure from your compressor. You need to start over and add freon and the proper amount of oil while watching your gauges. As mentioned, your compressor shut off due to an overcharge and the pressure in your system is similar to the air pressure in your tires.
ANOTHER Misconception. There is NO WAY to know HOW much oil to add and you never need to add oil unless you have had a catastrophic break in the system. The ONLY correct way to get the correct amount of oil is to remove the compressor and drain the oil and then add the ozs required for that compressor. You can add a tablespoon but no more if you feel you have lost some oil. Doug

And the beat goes on. The compressor on my system siezed up after being replaced last fall. Turns out the dryer had piled up allowing desicant beads through the system and resulting in siezed compressor. Had to replace the compressor, dryer & hose kit (obsolete dryer) and remove, clean and repair the condenser and evaporator coils. We have cold air now! Never try to do stuff half assed is the moral to this story.
