Refrigerator section not cooling properly

there are a few possibilities . You can leave the refrigerator door open for 3 minutes. Unit goes into liner protection mode. This opens the damper flap and runs the fan on high. The damper flap are notorious for breaking off. Some times stuck wide open – complaint fresh food freezing, or be stuck closed – warm in fresh food. Drop the fresh food damper and mullion assembly to inspect. Page 10 in manual.
Issues: Not cooling, cooling intermittently, melting/refreezing Ice in the freezer, Freezer cabinet Ice-cream/food
melting/re-freezing, Wide temperature variation in freezer (displays wide fluctuation)
Models: Plastic liner, Electronic control models only, Manufacturing dates between January 2005 – Sept 2007
Possible cause and Diagnosis:
A) Evaporator Fan: When inspecting the unit, if it appears that the Evaporator fan is the problem (I.e. running slow,
not running at all), Then:
1. Connect inspector and go to diagnostic mode. Run the Evap Fan in lo-med-hi speed using inspector and check
the RPM’s. Do this multiple times and note the value.
2. If the values for the same speed does not match or the hi-speed RPM is smaller than lo-speed rpm or the
inspector keeps displaying , then check the voltage to the Evap fan and also measure the
capacitance value between pin3 of J2 (GND) and Pin 4 . The meter should read >800 nF or 0.8 uF. If it reads below
0.5 uF or 500 nF, Then replace the main board. Note: this issue can also be caused by a bad Evap-fan motor so
you must diagnose for that too if the Evap fan is not running at all.
Pin3
Pin5
B) Condenser Fan: Connect inspector and go to diagnostic
mode. Run the Condenser Fan using inspector. If the fan does
not turn then check the voltage at the Fan and also put a meter
across across pin 3 of J2 (GND) and Pin 5 for C25 (should read

900 nF or 1 uF. If it reads below 0.5 uF or 500 nF, then replace
main-board). If all of these are ok, then diagnose the fan for
possible failure
Note:
AFTER REPLACING THE BOARDS, IT IS RECOMMENDED TO
FORCE A DEFROST TO ELIMINATE ANY FROST BUILDUP
(specially in the Evap fan cover/orifice) SO THAT ANY ICE
ACCUMULATION WONT DAMAGE THE EVAP FAN. ALSO, CHECK
RPM OF THE EVAP FAN AFTER REPLACEMENT TO ENSURE FAN
MOTOR HAS NOT BEEN DAMAGED or working properly after
