If your TXV is working correctly and the plate is separating the valve's bulb would read the low load and starve the coil, so that is a very accurate sugestion. About the water filtration, if the...
What is the suction pressure at the beginning of the cycle, this wil tell you about your txv and the amount of charge in the system. You should be looking for high fifties or low sixties. If it...
