DCM2: AC complete, replaced (8) F20x20x2, checked (2) AX49, both systems are fully functional and operating within manufacturer specifications at this time. Leak still undetected; Had helper spray water inside and outside of the unit, while I searched for leaks for an hour. TXV could possibly be malfunction causing the coil to freeze but no signs while performing test, also possible blower motor failing causing evaporator to freeze but blower motor amp draw had no indication of failure and belt was tight. Subcool and super heat are within designed parameters, TXV and blower motor don’t seem to be malfunctioning.
