where is your sub zero in the garage? Condenser is off the discharge of the compressor, you need to cool the refrigerant and change it, and change to a liquid in the compressor...... Are you thinking evaporator?

Expert:  Kcrand36 replied 1 year ago.

Should read change to a liquid in the condenser..... This liquid gets metered into the evaporator (inside the box) which absorbs the heat in the box, boils off into a gas, and returns to the compressor as a gas.

Expert:  Kcrand36 replied 1 year ago.

If your telling me Pressure, suction and liquid, either your compressor is not running or is defective.
