Found the Under Counter Refrigerator unit off. Turned on and tested. Found the compressor came on but the temperature in the box went up. One of the condenser fans did not work. There was no. heat being taken out of the box. Got a saddle valve and installed it. Found the refrigerant pressure at 0 PSI when on. Leak tested the system. My electronic detector only went off when my detector was put inside the box. The evaporator coil is leaking. Added some refrigerant and the unit started to cool down and cycled off on temperature. Need to quote.
