Fridge 3 — 21QT powered fridge for Tesla Model 3 sub-trunk

One caveat is that new Tesla doesn't turn on the 12V outlet at the Sentry mode. Camp mode needs to be turned on to enable the 12V outlet. This is not a big deal since the cabin needs to be cool for the fridge to work properly --- Otherwise the fridge will overheat and stop working.

For Model Y, there is a power socket located on the left side of the rear trunk, which makes it quite easy to connect our Fridge 3. For Model 3, our fridge can get power from the front cigarette lighter of Model 3 via our 3-meter-long cable.

Absolutely. Our fridge is designed to be universal, meaning that it can run off of the cigarette lighters found in both gas and electric cars.

Please make sure the refrigerator is in MAX mode, because the temperature cannot be adjusted in ECO mode as we designed it.

1. Check Bluetooth and Location Settings:

• Ensure that Bluetooth is enabled on your mobile phone.
• Make sure that location services (GPS) are turned on as well.

2. Reinstall the App:

• If the issue persists, try uninstalling the app from your mobile phone.
• Download and reinstall the app from the app store.

Yes, Fridge 3 is compatible with portable power stations, portable batteries, and other charging methods. However, it requires a voltage of DC 12/24V or AC 100-240VAC for proper operation.

Fridge 3 is compressor.

Our fridge can work for 24 hours. The power consumption value is around 0.185-0.195 kWh/24h.Here we have conducted a series of tests to show that our fridge won’t cost much power.When the Camping Mode is enabled, your car will be locked while the 12V battery continues to provide power, keeping our fridge running. We tested the fridge at a temperature of -2°C with Camping Mode on, leaving it in the car for 12 hours overnight. Our results showed that the electricity consumption only decreased by 2%.This indicates that the main power consumption is not from our fridge but rather from the Sentry Mode drawing power from the car.

As for the situation, you can set 12v battery voltage protection level on the panel of our product. There are three levels for your choice: H-M-L.

Refrigeration issues can be categorized into three types: slow refrigeration, failure to refrigerate, and incorrect temperature display. Here’s how to diagnose and address each issue:

1. Slow Refrigeration:

       Possible Causes:

•  High ambient temperature or overcrowding inside the refrigerator.

       Solution:

• Ensure there is adequate ventilation around the refrigerator.
• Place the refrigerator in a cooler environment if possible.
• Reduce the amount of food stored inside and allow space for better air circulation.

1. Failure to Refrigerate:

        Possible Causes: 

• Insufficient refrigerant or compressor malfunction.

        Solution:

• Check if the refrigerator compressor is operational.
• Set the refrigerator temperature to -4°F (-20°C) and place a cup of water inside.
• After twelve hours, check if the water is frozen.
• If the compressor does not work, email our customer support: titus@dohometech.com for further assistance. We will coordinate with the factory to resolve the issue promptly.

1. Incorrect Temperature Display:

        Possible Causes:

•  High ambient temperature or incorrect temperature settings.

        Solution:

• Adjust the temperature compensation value as needed.
• Contact our support team: titus@dohometech.com to guide you through the adjustment process based on your feedback.
• If the displayed temperature differs significantly from the actual temperature and the refrigerator freezes, consider replacing the refrigerator operation panel.

If the problem persists, it may indicate a faulty thermometer, and we will arrange to send you a replacement.

Make sure the refrigerator is in L position, otherwise F2 will be displayed.

The F4 and F5 errors indicate poor heat dissipation, typically occurring when the ambient temperature around the refrigerator exceeds 120°F (49°C). Here are steps to resolve these errors:

1.Increase Ventilation:

• Improve the ventilation around the refrigerator.
• Ensure there is adequate airflow to help dissipate heat effectively.

2.Optimal Placement:

• If using the refrigerator in a car, avoid placing it in a confined space or groove.
• Instead, place it directly in the trunk of the car to allow better airflow and heat dissipation.
