Common Reasons for
Refrigerator Not Cooling
1. Condenser Coils are Dirty
The condenser coils are usually located under the refrigerator. They dissipate heat as refrigerant passes through them. If the condenser coils are dirty, they won’t dissipate the heat effectively. The refrigerator will not be able to maintain the proper temperature.
2. Condenser Fan Motor
The condenser fan motor draws air though the condenser coils and over the compressor. If the condenser fan motor is not working properly. First check the fan blade for obstructions. Next, try turning the fan motor blade by hand. If the blade does not spin freely, replace the condenser fan motor. If the fan blade spins freely, use a multimeter to test the fan motor for continuity. If the fan motor does not have continuity, replace it.
3. Evaporator Fan Motor
The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator wont get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. If the motor is at times noisy, replace it. Finally, if the motor does not run at all, test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.
4. Thermistor\Sensor
The thermistor monitors the refrigerator temperature and sends the temperature reading to the control board. If the thermistor is defective, the compressor and evaporator fan may not run when necessary and your unit won't get cool enough. If the resistance does not change, or the thermistor\sensor does not have continuity, replace the thermistor\sensor.
5. Compressor
If the compressor is not working, the refrigerator won’t cool. If you have determined that all of the other components are working properly, check the compressor. If there is an open circuit, the compressor is likely defective. If you have determined that the compressor is defective, it must be replaced.

The refrigerator seems to be cooling properly but the fresh food indicator lights aren’t coming on at all so the customer can’t set the fresh food temperature. Also the ice maker is only getting 90 volts and the ice maker will not cycle. (Ice maker is brand new OEM).

It seems like there are two separate issues with your refrigerator. Firstly, if the fresh food indicator lights aren't turning on, it could indicate a problem with the control panel or wiring. This may be preventing you from setting the fresh food temperature. Secondly, the ice maker receiving only 90 volts and not cycling could suggest an electrical issue or a malfunction within the ice maker itself. It's advisable to have a professional technician inspect and diagnose both problems to ensure proper functionality and address any necessary repairs.
