Refrigerator and Freezer Cabinets
When the cabinet is plugged in
• Interior lights will illuminate on glass door models (see
previous page for light switch location).
• An electronic control with digital display will illuminate (if
installed).
• There may be a short delay before the compressor and/
or evaporator fan(s) start. This delay may be determined
by time or by temperature, which could be the result of an
initial defrost event that will last at least 6 minutes.
• The temperature control/thermostat may cycle the
compressor and evaporator fan(s) on and off together. Every
cabinet will require a defrost event to ensure the evaporator
coil remains clear of frost and ice buildup. Defrost is initiated
by a defrost timer or by the electronic control.
EXCEPTION – Models TSID, TDBD, TCGG, and TMW do
not have an evaporator fan(s).
• The temperature control/thermostat senses either an
evaporator coil temperature or air temperature, NOT product
temperature.
• An analog thermometer, digital thermometer, or electronic
control display may reflect the refrigeration cycle swings
of up and down temperatures, NOT product temperature.
The most accurate method to determine a cabinet's
operation is to verify the product temperature.
• Refrigerators with mechanical temperature controls will
defrost during every compressor off-cycle.
• Freezers with mechanical temperature controls will defrost
by time initiation as determined by a defrost timer.
EXCEPTION – Models TFM, TDC, THDC and TMW
require a manual defrost. The frequency of this manual
defrost will depend on the cabinet's usage and ambient
conditions.
• An electronic control with a digital display (if installed) will
show def during defrost.
NOTE: The display may have a short delay before
showing a temperature after a defrost event has expired
and instead show def during a refrigeration cycle.
• Models with an analog or digital thermometer may show
higher than normal temperatures during defrost.
• A refrigerator will use the evaporator fans to clear the coil
during defrost.
EXCEPTION – Models TSID, TDBD, and TCGG do not have
an evaporator fan(s).
• A freezer will use heaters to clear the evaporator coil during
defrost.
NOTE: The evaporator coil heater and drain tube heater
are only energized during defrost. Defrost is terminated
when a specific evaporator coil temperature is reached or
by a time duration.
