It is a small part, but it plays a very important role in electronic appliance operations. The trouble with fuses is that they can be located in some very interesting yet hidden areas of your fridge. Finding them is half the battle and takes the most work.
There is a thermal fuse that is connected to some red wires in the panel accessible to the outside. That is just one location as there may be two fuses on the control panel on the lower outside fridge panel. But there may still be one more location depending on your Dometic fridge model.
To learn more about this topic and where those fuses are, just continue to read our article. It delves into the subject to give you the best information on where those pesky fuses reside. They are not always easy to find and a visual inspection is not always enough.
Yes, they do. Just about every electric appliance has a fuse somewhere in its electrical system. The fuses monitor the power sent to the appliance and when it gets too much, the fuses will blow and cut the power off.
Each RV fridge should have at least 2 and possibly 3 fuses in its electrical system. One location will be at the back of the unit in the compartment you have to access from the outside.
That is usually called the thermal fuse and it is located under some black shrink tubing connected to some red wires. The other two should be in the control panel. The control panel is usually on the lower left side of the fridge.
You need to pop the cover off to access this control panel. A visual check is not going to be enough of a check to see if the fuses are working or not. A multimeter will be needed to ensure that there is power making it through the fuse.
You can blow one of the two fuses, usually the glass model, and still have gas power to operate your fridge.
The thermal fuse is located in one of two places. It will depend on the model you own where this fuse is placed. It could be in the fridge at the rear behind the paneling or it can be located next to the compressor.
You may also find it near the gas line at the bottom of the exterior compartment right behind the fridge. The other fuses, and there may only be one and not two, is in the control panel or power module.
You have to take the front cover off to access the control panel. Once you have done that, you should see the fuses right away. They are not hidden but in plain sight.
Some RV owners and mechanics will tell you that the fuse should be in a black box. If you have one, look inside of it to find the fuse. However, at least one owner has reported that their RV did not come with a black box so the fuse maybe with all your other fuses.
The lack of a black box just tells you that the RV company wired the fridge to a different circuit.
The Norcold RV fridge seems to have 3 fuses on its control panel or power board. Two will look like the standard vehicle fuse and one will be the glass type that protects AC voltage circuits.
They are all very accessible and easy to change. The key is to make sure your fridge is unplugged before you work on any electrical system in this fridge. The glass fuse may be a bit harder to find as the automotive ones are sold just about anywhere.
The glass types may be dealer-only or found at dedicated electrical supply shops. There is a 4th fuse called the fridge fuse. It is located on the back of the Norcold appliance and you may need to access it from the outside.
This one is near the electrical panel that is on the back of your unit. However, not every Norcold model may have fuses in the same places. It seems that some Canadian models may be designed slightly differently.
Check your owner’s manuals for your specific Norcold model and see what it says about the exact locations of your fridge.
There seem to be 2 thermal fuses for this brand of RV fridge. The two fuses should be located inside the fridge unit and they will not be near any other fuse. Usually, Everchill places a wiring diagram on the back of the fridge to help you locate these two thermal fuses.
Other fuses may be on the fuse panel and that should not be that hard to locate. Unfortunately, the Everchill manuals are not very helpful. They do not provide locations for any of their fuses.
All they said in the troubleshooting guide was that if the fridge was not operating, then a fuse or breaker may have blown or tripped. They provide no other information on this little part.
We checked two manuals to be sure. You can talk to an Everchill dealer or call Lippert who makes this brand of RV fridge and see what they say about the fuse locations.
This company did not make finding all the fuses an easy task to do. This brand will have roughly 3 fuses you need to be concerned about. It is possible that other models from this company may have more or less fuses.
The thermal fuse is at the rear of the fridge and is very difficult to locate. It is normally behind a bunch of wires and you can only access it from the outside. Simply remove the panel and look for all the wires. Then somewhere behind those wires, you will find the fuse.
The other two fuses are supposed to be in the back of the fridge. That means you will be using the exterior compartment to replace these two fuses if they have blown/. One is the standard glass AC protection fuse and it should be easier to see than the thermal fuse.
The last fuse is called the inline fuse and it should be located at the back of the fridge. It is possible that it is placed inside the unit. You can look in your owner’s manual to see if it provides the exact location for these fuses.
Keep in mind that different models may have different wiring designs and the fuses may not be where you expect to find them.
There are always several reasons why this situation keeps happening. It is a good thing that fuses are not that expensive and are easy to find when you need to buy one.
The first reason that the fuse continues to blow after you replaced it is a short in the system. That short will send too much electricity to the fuse and when it is more than the fuse can handle, the fuse blows.
A second reason for this problem is that you may have bought a batch of fuses that are weak or defective. They are just not up to the task and cannot handle the amount of electricity they are rated to handle.
A third reason will be a defective fridge. There is n electrical problem in the fridge that needs to be tracked down and repaired before your fuse will remain intact.
A final reason will be an overloaded circuit. There are just too many electrical devices plugged into the same outlet and that power drain can blow fuses.
A blown fuse is just one of the many sources for this situation. There are some standard electrical devices you need to check along with the fuses to find the problem.
The breaker may have tripped due to a power surge or a faulty breaker. Or the battery has lost its charge and needs to be re-charged to get it working again. Or you have a short somewhere in the system that is cutting off your power supply.
If all of those components are working well, and the fuse has not blown yet, check your inverter to see if it is operating normally. Finally, double-check your extension cord to make sure you are connected correctly to shore power.
This is just the tip of the iceberg when it comes to this situation.
Fuses may be a small part of your electrical system but they play an essential role in your RV life. Without fuses, your appliances would not be protected and could be damaged if not for the fuse.
However, despite their importance, these little parts can blow for any number of reasons. Just make sure to have a multimeter on hand as a visual check is not good enough to discover if the fuse has blown or not.
