This was the first summer that we had planned a camping trip in advance, and we had temperatures in excess of 90 degrees. Unfortunately, the refrigerator in our Forest River Shamrock 23IKSS travel trailer struggled to maintain cold in these high temps (the freezer had no issues keeping cool).

We first assumed that since the chilling was taking place at the top of the fridge, the cold air didn’t reach the bottom because there was too much food within. As a result, we purchased a tiny fan from Amazon and utilized it to circulate the air. Unfortunately, this did not assist us solve our situation.

We discovered that the problem was most likely due to too much heat building up in the refrigerator’s outside section after doing some investigation. We bought some fans from Amazon that came with a thermostat, and they appear to have solved all of our issues.

We’ll break down everything I did to have these fans installed in this post, as well as include a video and step-by-step photos.

On hot days (90 degrees or more), how do you keep your RV refrigerator cool?

To begin, we purchased two sets of fans that could be connected to a single temperature controller. We purchased a twin fan to mount on top of the fins, which would pull air from the compartment’s top and blast it down through the fins.

We also built a triple fan system to assist expel the heat from the top compartment now that air is flowing over the fins. The temperature controller, which has its own thermostat that we put in the top chamber, controls both sets of fans.


So let’s get started. Remove the compartment covers from the top and lower compartments first. To do so, turn the two screws at the bottom 90 degrees, allowing each cover to be removed.


A stencil was included in the package we ordered. Begin by pasting the stencil to the inner wall board and tracing the area you’ll be cutting off.


After you’ve laid out all of your lines, you can start cutting the blank out. Look behind you before cutting to make sure there aren’t any cables behind it.


After the void for the three fans has been filled, it’s time to install the double fan on top. The cables should be slipped down the left side of the refrigerator compartment and the fan should slide in above everything.


Once the fan is in position, it may be zip tied down to keep it in place.


We went on to the bottom, triple fan now that the higher fan was installed. Begin by fishing the wire along the left side of the refrigerator cabinet in the same manner.


Place the fan in its final resting position while it is still dry.


Pre-drill a hole and screw the device in place after you’re satisfied with the position and fit. Make sure the screw isn’t overtightened. Rep for each of the four screw holes.


We can now proceed to the final steps after all of the fans have been installed. We zip tie the temperature sensor up by the fins, which is the hottest part of the refrigerator cabinet, to keep it cool.

The two fans, the thermostat, and the electricity are then connected.


I suggest turning on the fans at full blast first, then setting your lower limit for them to turn on automatically. We’ve discovered that 70 degrees will enough.

Good luck, and I hope that installing a few of fans in your RV fixes all of your cooling issues. Take advantage of the camping seasons!
