Tips For Fixing Dometic Fridge Error Code 12
1. Check The Power Cord
It is the power cord that is going to be a problem when you are looking at the Dometic fridge error code 12.
To remove the error code 12 on a Dometic refrigerator, it’s essential to see whether or not the power code is damaged. If the power cord is damaged, this is where the problem lies.
Look at the entire power cord to see if it is intact.
Sometimes, a part of the power cord is going to be bent or damaged to the point of no return. If that is the case, your best option is to replace the power cord.
Another issue might have to do with the power cord simply not working.
This can happen with older Dometic fridge models as they begin to age. Look at other steps in this guide and then go back to the power cord to replace it.

2. Look For A Blown Fuse
You will have to assess the fuse in greater detail.
The issue with the fuse has to do with how it is set up and how it works when there is a power surge. When too much power goes through the fuse, it is going to spark and then give out.
A blown fuse in a Dometic fridge will lead to this error code and it has to be replaced.
You will not be able to fix the blown fuse in a Dometic fridge, which means it has to be swapped out. Look for a good replacement fuse and then change it as soon as you can. The error code 12 will go away.
3. Inspect The Circuit Breaker
Another issue can do with the circuit breaker.
If there was a power surge with the Dometic fridge, this can become a major problem. It will create a situation where the circuit breaker does kick into action due to the power surge and the power will not go through to the RV fridge.
You will have to address this by toggling it back into the on position.
This is how you are going to get the power to go through to the Dometic fridge again.
Always take a peek at the circuit breaker in a situation such as this to make sure it’s in working condition and nothing is damaged.
4. Check The Main Connection Point
You will have to go back and take a look at the connection point too.
Since you are aware the main issue has to do with the connection point, you will have to take a detailed assessment of what is going on with the Dometic fridge.
It is important to look at what is going on with the connection point and whether or not the power cord is connected properly.
If it is not, this is where the problem lies.
You will either have to replace that connection point or see what can be done to repair it.
Final Thoughts
It is important to go through these steps to fix the Dometic fridge error code 12.
To remove the Dometic fridge error code 12, it’s time to look at the power issue it’s highlighting. The main power issue can be a damaged or poorly connected power cord. Replace the power cord if this is the case. Another issue can involve a blown fuse or a tripped circuit breaker.
It’s best to work your way through the entire circuit to see where the issue lies with the RV fridge.
An RV fridge that is not getting enough power will not work. This is not only about the error code 12 but also about how the RV fridge is going to keep food cool. It won’t until the problem is fixed.
