How to Reset the Thermal Fuse in Your Dometic RV Refrigerator?

Resetting the thermal fuse on your Dometic RV refrigerator is very easy. Follow these steps to restore it to working order.

Step 1: Gather the necessary tools

To begin, make sure you have the following tools handy: a screwdriver (Phillips or flathead, depending on your refrigerator’s model), a multimeter (for testing continuity), and a replacement thermal fuse (if needed).

Step 2: Disconnect the power

Before tinkering with any electrical components, it’s crucial to ensure your safety. Start by disconnecting the power source to the refrigerator.

Switch off the circuit breaker that supplies power to the refrigerator or unplug the power cord.

Step 3: Access the thermal fuse

To access the thermal fuse, you’ll need to remove the refrigerator’s access panel. Locate the panel, which is typically situated at the back or bottom of the unit.

Unscrew the panel using your screwdriver, being mindful not to lose any screws.

Step 4: Locate the thermal fuse

With the access panel removed, you’ll now have a clear view of the internal components.

Look for the thermal fuse, a small device typically shaped like a cylinder or a rectangular box.

The thermal fuse is designed to protect the refrigerator from overheating.

Step 5: Test the thermal fuse

Using your multimeter, set it to the continuity testing mode. Gently touch the multimeter probes to the thermal fuse’s terminals.

If the multimeter indicates a lack of continuity (i.e., no electrical flow), it means the thermal fuse has blown and needs to be replaced.

If continuity is present, the thermal fuse is not the cause of the problem, and you should investigate other potential issues.

Step 6: Reset or replace the thermal fuse

If the thermal fuse has blown, it’s time to reset or replace it. Some models have a reset button on the thermal fuse itself.

If your refrigerator has this feature, press the reset button firmly to restore the connection. Not all models include a reset button.

In such cases, you’ll need to replace the thermal fuse with a new one.

Step 7: Install the replacement thermal fuse

Make sure you have the right replacement part if you need to replace the thermal fuse.

Carefully remove the old thermal fuse by disconnecting any wires or connectors attached to it.

Install the new thermal fuse in the same position and reconnect any wires or connectors.

Step 8: Reassemble and test

Once you’ve either reset or replaced the thermal fuse, it’s time to put everything back together.

Secure the access panel using the screws you previously removed. Double-check that all connections are secure and properly attached.

Finally, plug the power cord back into the electrical outlet or switch on the circuit breaker.

Step 9: Monitor refrigerator functionality

After resetting or replacing the thermal fuse, monitor your refrigerator’s performance closely.

Allow the refrigerator to run for some time and ensure that it is cooling properly. Check that the temperature remains stable and that the refrigerator is functioning as expected.

If the problem persists, you may need to consult a professional for further assistance.

Symptoms of a Faulty Thermal Fuse in Your Dometic RV Refrigerator

No Power or Cooling

When your Dometic RV refrigerator fails to power on or cool effectively, a faulty thermal fuse may be to blame.

The thermal fuse acts as a safety device, shutting off power to the refrigerator if it detects excessive heat.

If the fuse is blown, it disrupts the power supply, leading to a complete loss of functionality and cooling capability.

Tripped Circuit Breaker

If your Dometic RV refrigerator’s circuit breaker keeps tripping, you may have a thermal fuse problem.

A thermal fuse blows, creating an electrical imbalance, causing the circuit breaker to trip, preventing further damage.

Overheating Refrigerator

A faulty thermal fuse can cause your Dometic RV refrigerator to overheat. Excessive heat may be observed around the refrigerator’s compressor or the back may feel unusually warm.

In the case of a malfunctioning thermal fuse, the refrigerator can’t regulate its temperature properly.

Inconsistent Temperature

Control If your Dometic RV refrigerator experiences erratic temperature fluctuations, it could be due to a faulty thermal fuse.

A blown fuse disrupts the refrigerator’s ability to maintain a steady and desirable internal temperature.

It is possible to spoil your food or beverages while traveling if they are not properly cooled or frozen.

Burnt or Damaged Fuse

Physically inspecting the thermal fuse is another way to identify a fault. If you notice a burnt or damaged thermal fuse, it’s a clear indication that it needs to be replaced.

Any signs of discoloration, melting, or visible damage suggest that the fuse has blown and is no longer functional.

What affects the thermal fuse performance on a Dometic RV refrigerator?

Here are some factors that can affect the thermal fuse’s performance:


The thermal fuse is designed to protect the refrigerator from excessive heat. It can overheat if the cooling system fails, or if the condenser coils are dirty and obstructed.

The refrigerator can be shut down if this increased heat blows the thermal fuse.

Electrical Surges:

Sudden electrical surges or fluctuations in the power supply can impact the thermal fuse’s performance.

These surges can cause the fuse to blow, cutting off power to the refrigerator as a safety measure.

Using surge protectors or voltage regulators can help mitigate the risk of electrical surges and protect the thermal fuse.

Age and Wear:

Like any electrical component, the thermal fuse can experience wear and tear over time. Aging components can become less reliable and more prone to failure.

If your Dometic RV refrigerator is several years old, the thermal fuse might be more susceptible to issues.

Regular maintenance and inspections can help detect any signs of wear and replace the fuse as needed.

Excessive Current or Faulty Wiring:

excessive current or faulty wiring

Electrical problems, such as loose connections, frayed wires, or excessive current, can affect the thermal fuse.

These issues can lead to irregular electrical flow and cause the fuse to blow or malfunction.

Incorrect Installation or Replacement:

Improper installation or replacement of the thermal fuse can also affect its performance.

Dometic RV refrigerators require the correct fuse specifications, so follow the manufacturer’s instructions.

Incorrect installation or using a fuse with the wrong ratings can lead to premature failures or inadequate protection.

How to Maintain Your Dometic RV Refrigerator’s Thermal Fuse?

Dometic RV refrigerators require a thermal fuse for proper operation. The following steps can help ensure the thermal fuse’s optimal performance and reliability:

Keep the Refrigerator Clean:

Regularly clean the interior and exterior of your Dometic RV refrigerator. Remove any food debris, spills, or residue that may accumulate over time.

Clean the condenser coils once or twice a year to prevent dust and dirt buildup, which can lead to overheating.

Check for Proper Ventilation:

check for proper ventilation

Adequate ventilation is crucial for the refrigerator’s cooling system and the thermal fuse’s performance.

Ensure that there is enough space around the refrigerator for proper air circulation.

Avoid blocking the vents or obstructing the airflow by placing items too close to the unit. This helps prevent overheating and ensures efficient cooling.
