Initiating a Manual Defrost
Cycle
Defrost cycles are usually initiated automatically
based on time or demand. Manual defrost is also
available.
Manual defrost is available if the unit is running
and the evaporator coil temperature is less than or
equal to 45°F (7°C).
Other features such as door switch settings may
not allow manual defrost under some conditions.
To initiate a manual defrost cycle, press the
Defrost Key as shown in Figure 71.

The display then shows the Defrost display. The
bar indicator shows approximately how much
time remains to complete the defrost cycle. The
bar indicator in Figure 72 shows that the defrost
cycle is about 25% complete.
