Ive got a fridge that the coils keep freezing up on. Condenser is clean. Fans are working. I installed a bullet valve to get a suction reading which is 0 while running. Entire line set coming from the inside coil is frosted over. Is that normal for a fridge/freezer combo? Im pretty sure defroster is working but I dont have a good way to verify with this one. Inside coil is visibly freezing up after about a month. I through a very small amount of gas in it and got the low side up to about 4 psi. Fridge is almost 20 years old so I cant hurt it.
Also, at what point is the low side supposed to read 103psi? Is that a static charge rating only?
