Operation Overview - GE Adora DFE29JG Technical Service Manual

Normal Operating Characteristics
Liner protection mode will turn on either the fresh food
or freezer fan if the doors or drawer are open for more
than 3 minutes respectively.
The condenser fan may run without the compressor
operating.
Dispenser will not operate with either fresh food door
open.
Fan(s) running without the compressor operating is
normal.
The variable speed compressor uses an inverter like
previous variable speed.
The compressor will start at high speed for 1 minute,
then may change to a lower speed, based on fresh
food and freezer temperature. This may be perceived
as a noise issue.
There is a 20-second compressor delay on power up,
but fans will start immediately if cooling is required.
Compressor maximum-run time is limited to 6 hours
and the compressor minimum-off time is 2 minutes.
If either fresh food door is open when the freezer
drawer is opened, the freezer LEDs on the bottom of
the left fresh food door will not come on.
When either of the fresh food door(s) or freezer drawer
is opened, the fans will turn off.
The box type fans used on these models have different
sound characteristics than fans used on previous
models. Consumers may perceive this as a noise issue.
On power-up or board reset, if the icemaker rake is not
in the home position, the door icemaker heater will turn
on for 1 minute (2 minutes for freezer icemaker) before
power is applied to the rake motor. This could take up
to 3 minutes to complete. The mold temperature is only
limited by a 210°F one shot thermal cutout.
Note: The mold can get very warm.
Note: A loud buzzing sound may be heard every 20
to 40 minutes if the refrigerator is not connected to a
water supply, Turn off the icemaker until connected.
The duct door is operated by a motor and the
consumer may notice a very distinct motor sound
when the duct door opens and closes.
When either fresh food door is opened while dispensing,
the dispenser will stop. After the door(s) are closed, the
dispenser will not restart until the dispenser paddle
switch is released and pressed again.

Operation Overview

Liner Protection Mode
Liner protection 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, liner
protection mode will reset.
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.
Refrigerator Operation
GE and Profi le models operate in the following states:
• Pull Down
• Cooling Operation
• Fresh Food Cycle Defrost
• Pre-Chill
• Fresh Food Only Heated Defrost
• Fresh Food and Freezer Heated Defrost
• Dwell
• Post Dwell
Pull Down
Pull down occurs any time the refrigerator is plugged in
and the freezer temperature is above 60˚F.
The 3-way valve moves to the B position. Compressor
start is delayed for 20 seconds. The compressor will
start and run at HIGH speed for 1 minute, then change
to LOW speed (variable speed models only). The freezer
fan will run at HIGH speed.
When the freezer temperature falls to approximately
12˚F, the compressor will change to HIGH speed
and the 3-way valve will move to the A position,
delivering refrigerant to both the fresh food and freezer
evaporators. The fresh food fan will begin running at
HIGH speed and the freezer fan will continue to run at
HIGH speed.
