Understanding the Problem
If your FPSC2277RF refrigerator is running but not maintaining cold temperatures (or the freezer is frosting up while the fridge is warm), the issue can come from several common refrigeration system faults. Typical failure points include a defective evaporator fan, failed defrost system, bad temperature sensors/thermistors, a faulty condenser fan or a failing compressor or sealed-system leak. Noise, ice buildup, or high interior temperatures usually point to specific subsystems that need inspection. Start by visually inspecting airflow paths and listening for fans and the compressor. Many cooling problems are caused by airflow restrictions (blocked vents or iced evaporator coil) or failed small components like the evaporator fan motor or defrost heater/thermostat. Electronics (main control board or user interface) and sensors can also cause incorrect temperatures, but mechanical and sealed-system issues should be ruled out first because they are the most common and often the most urgent to repair.
Common Symptoms
Warm refrigerator compartment, freezer not cold, frost/ice buildup on evaporator coil, loud or abnormal fan/compressor noises, or fridge cycles constantly without achieving set temperature.
Common Causes
- Defective evaporator fan motor preventing cold air circulation
- Failed defrost system (defrost heater, thermostat or control) causing iced-over evaporator
- Faulty thermistor/temperature sensor or main control board giving incorrect temperature readings
- Condenser fan or condenser coil blocked/failed, reducing heat rejection
- Compressor starting device failure, compressor seizure, or sealed-system refrigerant leak

Helpful Repair Tip
Confirm the faulty part by first checking whether the compressor runs and both fans (evaporator and condenser) are spinning; if the compressor runs but evaporator fan is dead, replace the evaporator fan motor—if fans run and evaporator coil is frozen, test the defrost heater and thermistor/defrost thermostat next.
Frequently Asked Questions
How do I tell if the evaporator fan or condenser fan is the problem?
Open the fridge and listen: with the compressor running, you should hear the evaporator fan inside the freezer or rear/under compartment. If the compressor runs but you hear no airflow or a loud grinding/rattling from the fan area, the evaporator or condenser fan motor is likely bad. Visually inspect for blocked vents, ice around the evaporator fan, or debris near the condenser fan. A non-spinning fan that doesn't run when nudged (with power off) usually needs replacement.
My freezer is icy but the fridge is warm — does that mean the defrost system is bad?
Yes, heavy frost or ice on the evaporator coil combined with a warm refrigerator section often indicates a defrost system failure (failed defrost heater, defrost thermostat, or defrost control). When the defrost system fails the coil stays iced over, blocking airflow into the fridge. To confirm, manually defrost the evaporator (power off and let ice melt) and then observe whether frost returns quickly; if so, test the defrost heater for continuity and the defrost thermostat/thermistor for correct resistance per service manual, and replace the defective component.
