Description
3 Turbo Compressor 6. If the 'Turbo Freeze' button is pressed under defrost mode, 88 LED
Freeze Evap. Fan Motor will flash 'T.F'; however, 'Turbo Freeze' mode will start after defrost mode is
Cond. Fan Motor terminated.
88 LED 7. If defrost mode occurs during 'Turbo Freeze' mode, the defrost mode will
start after the turbo freeze mode is terminated.
4 Determination 1. Defrost mode will initiate under the following condition:
of Defrost 2. Make sure 6 hours have passed since the last defrost mode was terminated.
- F sensor ERROR
- Defrost sensor ERROR
- Door sensor ERROR
- 14 hours have passed since last defrost mode was terminated.
- Doors have been open for more than 10 minutes.
- Compressor has been running for more than 85% of the time.
3. If defrost mode does not initiate under errors described above, it will also trigger if:
- Compressor has been operating for more than 6 hours.
4. where, the defrost period is 6 hours when the appliance is initially powered up.

A. Pre-cool step
a. It prevents from excessive high temperature during defrost mode.
b. Compressor, condenser fan motor and evaporator fan motor will run
continuously during the pre cool step continuously during the pre-cool step.
c. 88 LED shows the temperature inside the cabinet.
d. If F-sensor temperature is lower than -16℉ or maximum time of pre-cool
step interval for 15 minutes, the pre-cool step will turn off.
e. 'Turbo Freeze' mode is enabled just once during pre-cool step.
B. Heater defrost step
a. To minimize the risk of icing up, the defrost heater will run periodically.

c. The defrost heater will stop running if the temperature of D-sensor
rises above 43℉(6℃) or exceeds a maximum running time, 30 minutes.
d. If D-sensor temperature does not reach 43℉ in 30 minutes, error code will
be shown on LED display panel.
