Compressor
The compressor is located on the bottom layer (level one) of the refrigeration
system. If the compressor is causing excessive noise, check the mountings
to ensure there is no damage to the rubber or the washers, nuts and screws.
Before replacing the compressor, check all plugs and connections and
ensure the compressor electrics are operating correctly (see below). The
compressor must be supplied with consistent voltage over 220 volts. Ensure
the voltage does not drop at start-up. If the voltage does drop, ensure the
refrigeration system has a direct power supply (not from a multi-box or
extension cord).
