DEFINITIONS OF MALFUNCTION DIAGNOSIS CODES AND
CORRESPONDING CORRECTIVE MEASURES
• If the FF code flashes with a green light, this indicates that the freezer compartment interior
temperature has been unusually high for some time (2–6 hours). Check the following items
immediately:
• Check for objects that may prevent the freezer or the refrigerator compartment door from closing
completely.
• Minimize opening and closing of door to lower the interior temperature of the freezer compartment
quickly. If the reset key is pushed the FF light will go out and the diagnostic system will continue
checking for any other malfunctions. If the normal operation code key is pushed and the PF code light
comes on but the normal operation code light does not, there may be a power failure or another
temporary interruption of power source.
• Wait until it is cool to call for service (may take several hours).
(1) FREEZER COMPARTMENT MALFUNCTION: “FF”
• If the PF code flashes with a green light, this indicates that the electricity has been interrupted for more
than 2 seconds. The freezer and refrigerator compartments should be checked. If the reset key is
pushed, the PF light will go out and a diagnosis can be made whether there are any other malfunctions
present. PF is not a mechanical malfunction.
(2) POWER SOURCE MALFUNCTION: “PF”
• If the dE code flashes with a green light, this indicates that the defrosting operation has not been
performed during the past 64 hours.
• If this code flashes, a service call is needed for repair work.
(4) DEFROSTING MALFUNCTION: “dE”
• If the CI code flashes with a green light, this indicates that the automatic icemaker is malfunctioning.
Check the following items immediately:
• Is arm switch of the icemaker blocked by ice cubes? (Remove the ice).
• Is dedicated icemaker water supply valve open? (Open valve.)
• Is icemaker arm switch in the “ON” position with the water supply piping connection not properly
installed? (Set to “OFF.”)
• Is thickness of ice more than 1.2 cm? (If thickness of ice is less, open the valve wider to increase the
water supply.)
• If the reset key is pushed, the CI light goes out and a check can be made whether there are any other
malfunctions. If the CI light flashes again, a service call is needed.
(3) ICEMAKER MALFUNCTION (AUTOMATIC ICEMAKER): “CI”
