should a Tab 360 have a refrigerator fan

Is it an Isotherm refrigerator? Is there a vent above the door or in the countertop?

My 360 doesn't have a fan, either.  I'm working on adding one myself.  I've attached photos of the space behind the refrigerator and a close up of the refrigerator control panel.  I can't figure out where the green and white wires are that go in the + and F terminals behind the frig - per the Service Bulletin issued to correct the mis-wiring problem.  I'm beginning to think I should just buy a fan and have it installed so I can turn it on and off - not through the refrigerator.  I certainly don't want the fan to trip a circuit protector.

Yoshi_TAB - thank you!  I looked for the Facebook post by the owner who installed a fan and could not find it.  The more I think about it I'm inclined to install a shelf behind the refrigerator and small fan with on/off switch.  Simpler is better.  The wiring behind my camper looks completely different than the wiring on the service bulletin with the fan.  

They rewired the extra fan behind the fridge in our 360CS to only come on when the fridge compressor is running. Our dealer also installed a quieter fan version. Overall made the camper usable.

It was impossible before that with the crazy loud fan running all the time any time power was applied to the camper in any fashion.

Hi @LauraC

I was able to get some photos.

The fan (just a big computer fan) has two wires.  The black one goes to a white wire which connects to the F position on the circuit board and the red wire from the fan   goes to the green wire which connects to the + on the circuit board.

Below you can see the condensor coil which goes the entire height of the fridge.  When the compressor runs, those coils get hot as they should as they are removing heat from the compressed refrigerate.  Having a fan certainly will help push the heat up and out the vent at the top and into the cabin area and help it run better.    I could feel the air get very warm, being pushed out by the fan when I started the fridge up.  Any good handyman or person can install.  Does not need to be a RV place.

I tried to look down the opening but could not get far enough in to see down....I need to bike more to squeeze in

I have a 360CS and had a fan that always ran.  I spoke with NuCamp and they were not sure (back in April 2025) how they were going to deal with it.  Eventually, the dealer said they were going to set it up so when the compressor is on, the fan comes on.

I have an early build 360. The isotherm 140 fridge works really well, no issues. However I have added a fan that comes on when the compressor runs to enhance the convective air pattern, drawing air from underneath up, behind, and out the top of the cabinet. In Florida this spring we did have a couple of days where the front of the trailer was in hot sun during the afternoon. The fridge kept up fine but it ran more than usual because that cavity was getting external heat. So I don't know if this mod was required necessarily but it seems beneficial to prolong the life of the refrigerator and reduce stress on the batteries. I used a good quality, quiet 120 mm computer fan. Those are four wire fans for pwm control but you can just use the black for negative and the yellow wire for positive and ignore the other two. (@yoshi_tab your pictures were very helpful.) As describe above the black wire goes to the F (fan) terminal on the control board on the back. The yellow wire goes to the "+" terminal. I mounted the fan about 18 inches off the floor at a 45° angle. It runs at full speed when the compressor comes on and uses about 0.1 amp.

Well in general we are very happy with the performance. Others feel it's too big and takes up counter space but we love not having to deal with ice, the fact that you can bring what you want including frozen food, and reach inside for a truly cold beer or a scoop of ice cream. Luxury camping. Our biggest issues have been related to airflow inside the unit when we overfill it. I've played with the small air vents underneath the cooling coils to find the right airflow and we are thoughtful about where we place items at the top so the opening doesn't get blocked. Obviously that closed drawer at the bottom is going to be the warmest spot but our Target temperature is 40 and we don't have a problem achieving that at setting two or three for the most part. I will say we are not hot weather campers, and we don't live in the desert. The biggest performance issue we've had is one time after 10 days in a humid environment we did get ice buildup on the coils. When we got to shore power I did a quick defrost. I think that's going to happen with any non frost-free refrigerator. So what is your non fan solution?
