How to Test and Change the Fan of a Beer Dispenser

When the fan of a beer dispenser is defective, it is often due to excessive heat exposure or an overload of dust which blocks it.

You can manually test the fan, clean it if needed, and test with a multimeter.

Consider replacing it when you experience any of these issues with your device:

• the beer dispenser no longer cools or the beer coming out is too hot;
• the outgoing beer is too cold;
• the device makes too much noise.

The beer dispenser has become an indispensable asset for both businesses and personal use, ensuring that each pour is at the perfect temperature and pressure. To ensure the beer remains cold, most beer dispensers come equipped with a built-in fan that circulates cold air. Like any mechanical component, the fan can become faulty over time, impacting the dispenser’s cooling efficiency. This article will guide you through how to test and replace the fan in a beer dispenser.

Disclaimer: Always remember that working with electrical appliances can be dangerous. If you’re not comfortable with these steps, it’s recommended to hire a professional.

Testing the Fan

Before rushing to replace the fan, it’s essential to ensure it’s indeed the source of the issue. Here’s how to test it:

1. Unplug the dispenser: Safety first. Always ensure the dispenser is unplugged before you start any work.
2. Inspect visually: Open the dispenser and locate the fan. Check for obvious signs of damage, such as broken blades, or dust and debris that might be obstructing the fan’s movement.
3. Listen to the fan: Plug in the dispenser and listen closely. A properly functioning fan should have a consistent sound. If it’s making rattling noises, it might be faulty or loosely fitted.
4. Check for airflow: Feel around the fan for airflow. If there’s no air movement or it’s significantly reduced, the fan could be the problem.

If after these tests you find that the fan is indeed faulty, it’s time to replace it.

Changing the Fan

1. Order the right fan: Ensure you have the correct replacement fan for your beer dispenser model. Using an incorrect fan can lead to inefficient cooling or other complications.
2. Disconnect the dispenser: Unplug the beer dispenser before starting your work.
3. Access the fan: Open the casing of the dispenser to access the fan. The location will vary based on your specific model, so consult your dispenser’s manual if necessary.
4. Remove the faulty fan: Detach the wires connected to the fan, noting their arrangement for reattachment. Next, remove the screws securing the fan in place and carefully take out the fan.
5. Install the new fan: Position the new fan in the same orientation as the old one. Secure it with the screws, and reconnect the wires in the same configuration as they were connected to the old fan.
6. Test the new fan: Close up your beer dispenser and plug it back in. You should hear the fan running smoothly and feel the airflow to confirm it’s working properly.

Conclusion

A functioning fan is essential for a beer dispenser’s optimal performance, maintaining the perfect serving temperature for your favorite brews. Understanding how to test and replace the fan can be a valuable skill for maintaining your dispenser. However, if you feel uncertain about any steps, it’s best to consult with a professional. Happy pouring!
