Commercial True Refrigerator Condenser coil blockage

What is a condenser coil?

The condenser coil is a vital component of your Commercial True refrigerator, responsible for releasing heat from the refrigerant to maintain a cool internal temperature. Located at the back or bottom of the unit, it consists of a series of metal tubes that carry the hot refrigerant gas. As the gas passes through the coils, it dissipates heat into the surrounding air, allowing the refrigerant to condense back into a liquid state.

What happens when the condenser coil is blocked?

When the condenser coil becomes blocked with dust, dirt, debris, or pet hair, it can’t effectively release heat, leading to a rise in internal temperature. This can cause the following problems:

• Refrigerator not cooling properly: Food may not be kept at a safe temperature, leading to spoilage and potential health hazards.
• Increased energy consumption: The compressor has to work harder to maintain the desired temperature, resulting in higher electricity bills.
• Premature compressor failure: Overheating can damage the compressor, leading to costly repairs or replacement.

How to identify a blocked condenser coil:

• Warm air coming from the refrigerator: If the air coming out of the vents feels warm instead of cool, it could be a sign of a blocked condenser coil.
• Unusual noises: The compressor may run louder than usual or make a clicking sound as it struggles to maintain the desired temperature.
• Frost buildup: Excessive frost on the evaporator coils inside the refrigerator can indicate a problem with the condenser coil.

DIY Solutions for a blocked condenser coil:

• Unplug the refrigerator: Before attempting any cleaning, ensure the unit is disconnected from the power source to avoid electrical shock.
• Locate the condenser coil: The condenser coil is usually located at the back or bottom of the refrigerator. Refer to your user manual for the exact location.
• Clean the coil: Use a brush attachment with a vacuum cleaner to remove dust, dirt, and debris from the condenser coil fins. Be gentle and avoid damaging the delicate fins.
• Rinse the coil (optional): If the coil is heavily soiled, you can rinse it with a gentle stream of water. Allow the coil to dry completely before reconnecting the power.

Preventive measures:

• Regular cleaning: Schedule regular cleaning of the condenser coil, at least every 3-6 months, to prevent buildup and ensure optimal performance.
• Keep the area clean: Avoid placing items near or around the condenser coil that could restrict airflow.
• Monitor performance: Pay attention to the refrigerator’s performance and be on the lookout for signs of a blocked condenser coil.

By following these tips, you can keep your Commercial True refrigerator’s condenser coil clean and prevent potential problems. Remember, if you’re unsure about any step or encounter difficulties, it’s always best to consult a qualified technician for assistance.
