The beer tap is a great way to get a homemade beer. This device is very practical and easy to use, but sometimes breakdowns occur: the dispenser may have a low flow rate, no longer turn on or no longer cool.
When the beer dispenser’s green light does not come on, you must check the elements that may be the cause of this failure:
- terms of use
- the gasket
- the electronic card
- the fan
- the temperature probe
The beer dispenser has become an increasingly popular device for homes and establishments alike, offering an optimal pour of your favorite brew right on demand. Many modern beer dispensers come with an indicator light system, with a green light typically indicating that the dispenser is at the perfect temperature and ready to serve. However, if you’ve noticed your beer dispenser’s light is failing to turn green, it’s important to understand why this might be happening. This article will explore some common reasons and potential solutions for this issue.
1. Temperature Fluctuations
One of the primary reasons the light might not be turning green is that the dispenser has not yet reached the ideal serving temperature. This can often happen when you first plug in the machine or load a new keg that hasn’t been chilled.
Solution: Be patient and give the machine time to cool to the appropriate temperature. If the light still doesn’t turn green, check your dispenser’s temperature settings to make sure they are correct.
2. Faulty Temperature Probe
The temperature probe monitors the internal temperature of the beer dispenser. If it’s malfunctioning, it might not accurately assess the temperature, preventing the light from turning green even if the beer is at the ideal serving temperature.
Solution: You can test the temperature probe with a multimeter or consult a professional. If the probe is found to be defective, replacing it should resolve the issue.
3. Malfunctioning Indicator Light
In some instances, the issue might lie with the light itself. If the bulb or LED is damaged or has worn out, it might not change color as it should.
Solution: To diagnose this, observe whether the light functions in other ways (e.g., turning red when it should). If not, the light element might need replacing. Consult your beer dispenser’s manual or a professional for guidance on replacing the indicator light.
4. Faulty Thermostat
The thermostat controls the dispenser’s cooling system. A malfunctioning thermostat may not properly regulate the internal temperature, causing the light to stay red.
Solution: A faulty thermostat may require professional repair or replacement. It’s advised to consult with a professional if you suspect a thermostat issue.
5. Dispenser Overload
If the beer dispenser is overloaded, either with too much beer or improper positioning of the keg, the temperature might not be adequately regulated, preventing the light from turning green.
Solution: Ensure you’re not overfilling or improperly placing the keg within the dispenser. If you’re unsure, refer to the dispenser’s user manual for guidance on correct loading procedures.
STUDY THE BEER DISPENSER ELECTRONIC CARD
To find out if the electronic card is defective or meets the requirements, it is necessary to check its input and output voltages.
- Dismantle the beer dispenser from below, then remove the protective cover that opens access to the electronic power board.
- Locate the thermoelectric module connected to the electronic board and its connector. It can be identified by its connection to 2 electrical wires.
- Set the multimeter to 20 VDC and place the two multimeter test leads on the two ends of the connector.
- If the electronic power board is receiving the correct power but the output voltages are incorrect, the board is faulty.
CHECK THE FAN
When a fan fails, it is often due to excessive heat or dust overload blocking it.
- Make sure the fan is clean and free of dust or other debris that might prevent it from spinning.
- Then remove the fan power connector on the control board.
- Set your multimeter to 20VDC, then plug in and turn on the brewer.
- Measure the fan supply voltage by putting 2 contact tips on the connector tips. If you cannot find the voltage, you will have to replace the power electronic board.
Conclusion
The indicator light on your beer dispenser serves as a simple but crucial element for ensuring your beer is dispensed at the perfect temperature. If the light on your beer dispenser is not turning green, several factors could be at play, from temperature fluctuations to a faulty thermostat. By understanding these potential issues, you can take steps towards diagnosing and addressing the problem. Remember, it’s always safest to consult with a professional if you’re unsure about any steps in this process. Cheers to a perfectly poured, perfectly chilled pint!
