1. Failure: Temperature Too High

User Checks

– Door Gasket: Inspect the door gasket for any signs of wear or damage that could allow warm air to enter.

– Hot Food Inside: Ensure that no hot food items are placed inside the refrigerator, as this can raise the internal temperature.

– Blocked Vents: Check for any blocked vents that could restrict airflow and affect cooling.

Engineer Checks

– Condenser Clogging: Inspect the condenser for any clogs or debris that could hinder its performance.

– Refrigerant Leakage: Check for any refrigerant leaks that could affect the cooling efficiency.

– Compressor Check: Perform a thorough inspection of the compressor to ensure it is functioning properly.

2. Failure: Frost Buildup

User Checks

– Frequent Opening: Minimize the frequency of opening the door to prevent warm air from entering and causing frost buildup.

– Gasket Condition: Inspect the door gasket for any damage or wear that could allow warm air to infiltrate.

Engineer Checks

– Heater Element: Test the heater element to ensure it is functioning correctly to prevent excessive frost buildup.

– Auto-Defrost System: Inspect the auto-defrost system to ensure it is activating and functioning as intended.

3. Failure: Water Leakage

User Checks

– Drain Hole Blockage: Check the drain hole for any blockages that could cause water to accumulate and leak.

Engineer Checks

– Broken Drain Tube: Inspect the drain tube for any cracks or breaks that could lead to water leakage.- Heater Malfunction: Test the heater to ensure it is functioning correctly and preventing ice buildup that could cause leaks.
