Haier Refrigerator: compressor failure

Professional Repair Guide

What is this symptom?

Experiencing compressor failure in your Haier refrigerator can lead to frustrating situations, such as the unit failing to cool properly or the compressor running intermittently. Common indications include a silent compressor, lack of cooling in both the fridge and freezer compartments, and power being on without functionality. Understanding the underlying causes can help you address the issue effectively.

Important Tips for Haier Models

  • Control board and thermistor issues have been specifically noted in Haier troubleshooting guidance as preventing normal compressor operation.

Possible Causes

Faulty start relay / start device

How to Identify: Repeated clicking sound with no compressor run; compressor fails to start but attempts to switch on; start device rattles when shaken or shows burn marks.

Part: Compressor start relay / overload protector

Control board not sending start signal

How to Identify: Compressor doesn’t start even in diagnostic/test mode with good wiring continuity; no voltage delivered to compressor start circuit.

Part: Electronic control board

Dirty condenser coils leading to overheating

How to Identify: Condenser coils are covered in dust/debris; compressor overheats, shuts down, or cycles frequently without cooling.

Part: Condenser coils

Refrigerant leak / low refrigerant level

How to Identify: Warm interior despite compressor running; oily residue near coils; continuous running without achieving temperature.

Part: Refrigerant lines / compressor system

Faulty thermistor or temperature sensor

How to Identify: Compressor fails to run normally but may run in test mode; inconsistent temperature readings; incorrect thermostat control behavior.

Part: Thermistor / temperature sensor

Compressor internal failure (mechanical)

How to Identify: No start with good start relay, control board, wiring; compressor windings show open circuit on multimeter; humming or hot compressor without cooling.

Part: Compressor unit

DIY Solutions

Clean condenser coils

Moderate 15-30 minutes
Tools Needed: vacuum cleaner with brush attachment, soft coil brush
  1. Unplug refrigerator and pull it away from the wall.
  2. Locate condenser coils (back or bottom access panel).
  3. Use brush and vacuum to remove dust and debris thoroughly.
  4. Replace access panel and plug in unit; monitor compressor behavior.
⚠️ Safety First: Always disconnect power before accessing components.

Inspect and replace start relay / start device

Advanced 30-60 minutes
Tools Needed: multimeter, screwdrivers, replacement start relay specific to model
  1. Unplug refrigerator and access back compressor area.
  2. Locate start relay / overload on compressor terminals.
  3. Remove assembly and test for continuity or physical damage.
  4. Replace with correct part if faulty and reassemble.
  5. Plug in and observe compressor startup.
⚠️ Safety First: High voltage risk; ensure power is off.

Burning smell from compressor area
Refrigerant leak suspected (oily residue or rapid loss of cooling)
Uncertain diagnosis after start relay and basic checks

Preventive Maintenance

  • Clean condenser coils: Compressor overheating and stress
    Frequency: semi-annually

Common Issues Reported by Users

  • Compressor overload due to a faulty start relay
  • Insufficient refrigerant due to leaks in the system
  • Compressor motor failure due to overheating or wear

User Suggested Solutions

  1. Check and replace the start relay. Unplug the refrigerator, locate the relay on the compressor, and test it with a multimeter. If faulty, replace it with a new one.

  2. Inspect for refrigerant leaks. Use a leak detector to find leaks in the refrigerant lines. If found, repair the leaks and recharge the system with refrigerant.

  3. Replace the compressor. If the compressor is locked up, it may need to be replaced. This involves disconnecting the old compressor, installing a new one, and ensuring proper refrigerant levels.
