Common Refrigerator Problems

Refrigerators are essential household appliances that keep food fresh and safe by maintaining a consistent, cool temperature. However, like any appliance, they can develop issues over time. Understanding common refrigerator problems can help homeowners identify and often resolve issues before they require costly repairs or replacements. Below is a comprehensive look at the most frequent refrigerator problems, their causes, and potential solutions.

1. Refrigerator Not Cooling Properly
Symptoms:

• Food spoiling quickly
• Fridge compartment warmer than usual
• Freezer works, but fridge doesn’t

Common Causes:

• Dirty condenser coils
• Faulty evaporator fan motor
• Malfunctioning thermostat or thermistor
• Defective compressor
• Low refrigerant levels

Solutions:

• Clean the condenser coils (usually located underneath or behind the fridge)
• Check and replace the evaporator fan if it's not spinning
• Test and replace the thermostat or temperature sensor
• Consult a technician for compressor or refrigerant issues

2. Water Leakage
Symptoms:

• Puddles under or inside the fridge
• Moisture buildup in the crisper drawers

Common Causes:

• Blocked or frozen defrost drain
• Cracked or misaligned drain pan

• Inspect or replace defective ice maker components

6. Fridge Running Constantly
Symptoms:

• Motor seems to never stop running
• High energy bills

Common Causes:

• Dirty condenser coils
• Improper temperature setting
• Warm air leaking due to faulty door seal
