Logically speaking, it is not possible for the system to discharge and recharge itself. That leaves out most high/low refrigerant issues. So, about the only thing that would cause it to stop working and then work fine the next day would seem to point to icing of the evaporator. I also see a reference to dripping inside the vehicle. That would also point to icing. As to the issue of icing.... The only combination of things that can cause icing is humidity and evaporator temperature below 32 degrees F. or 0 degrees C. So, what can cause that? Usually the low side cutout switch is allowing the low side pressure to go too low. This allows the temperature of the evaporator to go below the freezing point and icing to occur. One other possibility is a sticking expansion valve. This can cause the system to stop cooling or to cool excessively. Overcharged system is not a possibility as was previously mentioned. After all, how would it add refrigerant to a working system while in operation??? An undercharged system can cause icing, but the low pressure cutout switch should cause the system to cycle instead of icing. Therefore, I would look at the low pressure cutout and the expansion valve as the most likely causes of the problem.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
