What the Codes Mean
Check your frozen food. Has any of it started to thaw? A package may be holding the
freezer compartment door open. Don't open the door more often than absolutely
necessary while this code is displayed. Touching SYSTEM CHECK-RESET after the
freezer compartment temperature has returned to normal will erase the code.
Power to the refrigerator has been interrupted for more than two seconds. Check the
condition of food in both the fresh food and freezer compartments. Touch SYSTEM
CHECK-RESET to erase the code.
There is no fault with the refrigerator when the PF code flashes.
Check the icemaker. Ice clumps in the storage bin may have stalled the icemaker.
Follow corrective measures described in Troubleshooting Tips. If water supply to the
icemaker is not connected or not turned on, make sure the icemaker feeler arm is
in the STOP (up) position. The code stops flashing when problem is corrected or
SYSTEM CHECK-RESET is touched.
Something is wrong with the defrost system—keep doors closed to retain cold and call
for service. The code flashes until problem is corrected.
