5. A modified Standard Display appears. The bar indicator
will fill in showing time remaining to complete the
Defrost cycle. The bar indicator in the figure shows that
the Defrost cycle is 50% complete. When the Defrost
cycle is complete the display returns to the Standard
Display. See Figure 47.
If the unit is prevented from going into a Manual Defrost
(IE: Coil temperature more than 45 F (7 C) or on economy
mode etc.). A “Defrost Unavailable” Screen briefly
appears. The display returns to the Standard Display. See
Figure 47.
Terminating a Defrost Cycle
The Defrost cycle will terminate automatically when the coil
temperature reaches 58 F (14 C), or when the defrost timer
expires. The defrost timer is normally set for 45 minutes, but
can be set for 30 minutes. Defrost can also be terminated by
turning the unit off.
NOTE: If the defrost timer consistently terminates Defrost
because the evaporator coil temperature fails to reach 58 F
(14 C), have the unit checked by a Thermo King dealer to see
if it is working properly.
