This refrigerator has a evaporator for the freezer and one for the fridge. My problem started when I noticed the freezer getting warm. I couple days later both fridge and freezer failed. I ordered and installed a new freezer evaporator fan motor but nothing changed, both fridge and freezer remined warm.

I installed a piecing valve on the suction side of the compressor and I attached my gauge set. A negative pressure was observed on the gauge and so I recharged the system with R-134a freon. The fridge started cooling again but the the freezer remained at 71 degs F.

A couple days passed and the fridge started getting warm again which lead me to believe I have a leak. So my questions are:
1. Is it okay to recharge the system with freon infused dye to help locate the leak?
2. Why is the freezer not cooling?

Any pointers will help. Thanks.

20"hg is not a leak. Sounds more like a restriction. Check the head pressure.

Rick, thanks for checking in on me. This is just to give a little more history. With only a piecing valve installed on the suction side of compressor, on my second go around, I decided to vacuum the system and add the system required amount of freon. Once again the fridge temperature cooled to set point 34deg.F. But the freezer only went down by a few degrees. From 71 to 68.

My wife started loosing patience with me (lol) so she called a technician. After examining the system, he said there is leak and that he would return to add a filter dryer with dye (like you indicated) plus fittings for high and low pressure readings.

I am still very puzzled though as I am not understanding why only the fridge's evaporator coils are getting cold, while the freezer's remains warm.

Is there a diverting valve in the plumbing that switches freon back and forth between evaporators?
What is the freon flow path?

There's a 3-way valve. It has four positions but only uses three. A is open to the refrigerator evaporator and freezer evaporator in series so the refrigerant flows thru the fresh food evaporator and then into the freezer evaporator. B is open to the freezer evaporator only. C is not used. D is Closed to both fresh food and freezer evaporators during the off cycle
