Liner Protection Mode
The refrigerator incorporates a liner protection mode for the freezer section.
The freezer evaporator fan will start and run on high speed if the door has
been open for 3 minutes. Air will circulate into the fresh food section if the
damper is in the open position.
This mode is controlled by 2 timers. Timer #1 monitors door-open time. A 3-
minute door-open count begins when the door is opened. If 3 minutes elapse
before the door is closed, the liner protection mode will become active. Once
the door is closed, timer #1 resets and liner protection mode goes into
standby. In standby, normal fan operation resumes and timer #2 begins a 3-
minute door-closed count. If 3 minutes elapse without a door opening, the
liner protection mode will completely deactivate. If a door is opened within
the timer #2 door-closed count, the remaining time in the door-closed count
will be deducted from the timer #1 door-open count.
