The control has protective settings to prevent
short cycling of the compressor.
A. The compressor may run for up to 3 min.
after Step 2 is completed. Start the 10 sec.
count down for Step 3, once the display is
blank.
B. The defrost initiation may be delayed for up
to 6 min. after Step 3 is completed.
The display will show the temperature prior to
defrost once Step 3 is completed, even with the
protective delay timing out. The temperature
