Compressor failure is a relatively avoidable problem, however a costly expense in the refrigeration industry if general maintenance is neglected. By simply taking the time to inspect your compressor, you will receive years of operation without anxiety. Though you may not have the eye to notice broken valves, scored shafts, bent rods, overheating, or single phasing, you can (with these simple tips) recognize improper operation.
ATTENTION! ALWAYS UNPLUG YOUR UNIT BEFORE INSPECTING IT!
Step 1: Examine the Condenser Coils
The coils are located on the back of/or underneath your unit. Simply removing screws from the grill face will expose the coils and condenser. These coils condense the refrigerant. When the coils are clogged with dirt and debris they can’t efficiently relieve the heat of the compressed liquid. The result is more strain on your compressor. Working harder than it was designed to will lead to higher energy usage and a shorter life span in your fridge. Contaminants can include dirt, dust, and debris which will prevent the unit from dissipating the heat efficiently. Take notice of bent fins as well, as they are also detrimental in releasing heat from the system.
