Frigidaire Refrigerator — Noisy / Runs Constantly

About the Issue

If your Frigidaire refrigerator has become unusually loud or runs almost nonstop, the cause is usually airflow restriction, a failing fan motor, dirty condenser coils, or a temperature control issue that forces the compressor to operate longer than normal. Some models will also run constantly when frost blocks the evaporator or when sensors give inaccurate temperature readings.

Ignoring these symptoms can lead to warm temperatures, spoiled food, higher energy bills, and long-term compressor stress. Early diagnosis prevents further damage and restores normal cooling performance.

Symptoms (What You May Notice)

• Loud humming, buzzing, grinding, or rattling during operation.
• Refrigerator runs constantly or cycles very rarely.
• Warm fridge or inconsistent temperatures despite long run times.
• Noise coming from the back panel, freezer area, or bottom of the unit.
• Airflow from vents feels weak or uneven.
• Vibration noises when the compressor starts or stops.

Causes (Frigidaire-Specific Patterns)

• Evaporator fan motor wear causing buzzing, grinding, or intermittent noise.
• Condenser fan issues from dirt, worn bearings, or a failing motor.
• Frost buildup on the evaporator restricting airflow and forcing long run times.
• Dirty condenser coils making the compressor work harder to maintain temperature.
• Defective thermistors sending incorrect temperature signals to the control board.
• Compressor overload from high heat, restricted airflow, or age-related wear.
• Vibration from loose panels, drain tubes, or internal components.

Tests (How We Pinpoint the Fault)

• Listen for fan motor noise from evaporator and condenser sections.
• Check airflow volume and verify proper vent output.
• Inspect frost pattern for signs of defrost failure.
• Measure thermistor resistance and compare to actual temperatures.
• Evaluate compressor start-up and run characteristics.
• Inspect condenser coils for dust, debris, and overheating signs.
• Check for loose panels, tubing, or vibration points.

These tests separate normal operational sounds from component failures. All measurements are compared with Frigidaire specifications before any parts are replaced.

Repairs (What We Do to Fix It)

• Replace noisy or failing evaporator and condenser fan motors.
• Clear frost buildup and restore proper airflow.
• Deep-clean condenser coils to reduce compressor load.
• Repair or replace thermistors and temperature sensors.
• Correct vibration issues and secure loose panels or tubing.
• Verify full refrigerant airflow and overall cooling performance.

After repair, we confirm quiet operation, restore proper cooling cycles, and ensure the compressor and fans are running at correct levels.

Prevention (Keep It Quiet & Efficient)

• Clean condenser coils every 6–12 months.
• Keep vents clear and avoid blocking airflow.
• Ensure doors seal properly to prevent long run times.
• Check for unusual noises early before components fail.
• Avoid overloading shelves, which restricts internal airflow.
