Troubleshooting
Long operation time and a temperature
increase of housing and compressor are
normal during initial operation. Some of the sounds produced during initial
operation or at start-up will fade during normal
operation.
During initial operation, the appliance housing
may become warm to prevent condensation. At start-up and during operation, the
compressor may produce an audible sound
when starting or stopping
The sound of the refrigerant flowing through
the evaporator and compressor is normal. A
continuous or intermittent flowing sound after
operation is normal. During the defrosting process, thaw water may
drip onto the heating elements, causing audible
sounds in the evaporator.
