Do not store products which contain flammable propellants (e. Refrigerant starvation can lead to expensive repairs Signs of Low refrigerator Gas 1. This can cause high suction pressure, liquid refrigerant to flood back to the compressor, compressor slugging and possibly compressor failure. 3 The compressor is too hot • The compressor is only cooled by intake ( green circuit ) • Insufficient freon, prob-able leak. The reasons I choose freon was of it's accessibility (every car, home, refrigerator, trailer has some, you just have to have a pair of pliars and a drinking straw or ink pen), it's duration (all motor skills return in 5-15 minutes, vs. Step-by-Step Repair for a Refrigerator That Runs Too Much 1 Determine whether the refrigerator section is being cooled. This causes high compression ratios and low volumetric efficiencies, which results in low refrigerant flow rates. So with a little from this refrigerator repair guide your refrigerator will up and running in no time. There will be a tag on the refrigerator that will tell you how many ounces to put into the system. 170 Factors contributing to refrigerator cycling losses The capillary tube can be assumed to be adiabatic, because there is negligible flow through the suction line.
