Where’s the job?

Overview

Repairing a fridge with temperature regulation issues involves diagnosing problems with the thermostat, sensors, or cooling system. Common faults include a malfunctioning thermostat, poor sensor calibration, or issues with the control circuitry. Skill level is around 3 / 5, requiring basic electrical aptitude and an understanding of refrigeration principles. Typical repairs can take between 1 – 2 hours depending on the fault.

Safety First

• Disconnect the fridge from mains power before starting any repair work.

• Allow the unit to defrost and stabilise to avoid electric shock.

• Wear insulated gloves and use proper tools for handling electrical components.

• Be cautious around refrigerant lines and components; damaging seals can lead to leaks.

• Work in a well-ventilated area if refrigerants or chemical smells are present.

Tools & Materials

Step-by-Step

1. Unplug the fridge and remove the back panel to access the control board and thermostat.

2. Visually inspect wiring connections and components for signs of wear, corrosion or damage.

3. Use a digital multimeter to test the thermostat’s electrical output and check sensor values.

4. Assess other components such as the evaporator fan and compressor for proper operation.

5. Replace any faulty parts, such as the thermostat or damaged wiring, and secure all connections.

6. Reassemble the panel and plug the fridge back in – monitor for error codes or unusual behaviour.

7. Allow the fridge to stabilise before taking final temperature readings.

Completion Checks

• Fridge maintains a stable, correct temperature after repair.

• No error codes or unusual noises are present.

• All electrical connections are secure and components function as expected.

• Temperature readings are consistent with the thermostat settings.

When to Call a Pro Instead

If the issue involves sealed system faults, refrigerant leaks or compressor malfunctions, it is advisable to consult a qualified appliance repair technician with experience in refrigeration systems. This ensures compliance with safety regulations and protects warranty conditions.
