How to Fix a Fridge Running Constantly

Overview

A fridge that runs constantly wastes energy and can indicate a problem. This guide covers diagnosing and fixing the issue.

Step-by-Step Fix

1. Firstly, locate the thermostat dial inside your fridge, usually near the light. Ensure it's not set to the coldest possible setting, as this will force the fridge to run more frequently; adjust it to a medium or recommended setting (often 3-5°C or 37-41°F) and observe if the running cycle improves over a few hours.
2. Next, unplug your fridge from the wall socket for safety before proceeding. Locate the condenser coils, which are typically found on the back of the fridge or sometimes underneath it, and then use a vacuum cleaner with a brush attachment to carefully remove any accumulated dust and debris, paying attention to all accessible surfaces.
3. To check the door seal, open the fridge door and place a piece of paper or a thin bank note between the door and the fridge frame, then close the door. If you can easily pull the paper out, the seal is loose and allowing cold air to escape, indicating it may need to be cleaned thoroughly or replaced if damaged.
4. Check the interior of your fridge to ensure it's not packed too tightly, as this can block the internal vents and restrict cold air circulation. Rearrange items to allow adequate space around walls and vents, ensuring air can flow freely to cool all compartments effectively.
5. If the issue continues after completing the above steps, the problem might lie with a faulty thermostat or a struggling compressor. At this point, it's generally best to consult a qualified appliance repair technician for a professional diagnosis and repair, as these components are complex and can be dangerous to tamper with.
