Correct the front fan problem first. The front fans must be running when the
compressor is running. Failure to have the front fans running continuously
will give you high pressure readings. You may have water vapor in the
system. Water can get into the system by opening a fitting or replacing a
component. What happens is the water gets mixed with the freon and
circulates in the system. As the water vapor passes through the expansion
valve it freezes, plugging the valve. You don't say what the low side
pressure reading is when the high side is at 350 lbs. Make sure that the
pressure switch located behind the right front wheel is NOT jumpered. A
plugged system should pull a low pressure and shut off the compressor. Check
all fittings for leaks using soapy water and correct as necessary. Then pump
down the system for a good hour. Hope this helps.
