If you have a Dometic RV refrigerator that isn't working, one of the first things you should check is the control panel to see if the E7 code is displayed. This code indicates that there is a problem with the fridge's evaporator fan. The fan circulates air over the coils to help keep them cool and prevent frost buildup. If the fan isn't working, your fridge won't be able to properly cool itself and your food will spoil.
There are a few things that could cause the E7 code to appear on your Dometic RV refrigerator:
1. The most common cause is a faulty evaporator fan motor. If this is the case, you'll need to replace the motor in order to get your fridge working again.
2. Another possibility is that there is something blocking the path of the evaporator fan blades. This could be something as simple as dirt or dust build-up, or it could be a more serious issue like a piece of debris caught in the blades. Either way, you'll need to clean or repair the fan in order to fix the problem.
3. In some cases, an E7 code can indicate that there is a problem with one of the fridge's sensors. If this is true, you may need to replace the sensor in order to get your fridge working properly again.
