Do you need to pull refreg to do this job?
Not at all. Everything you need to fiddle with is on the backside of the fridge under the access vent covers.
Back in the day before slides, fridges mounted with the lower access vent in the side and the upper vent was on the roof so you had a nice natural draft to keep the cooler ambient air moving (and some slide campers are still like that, fridge mounted on the non slide side.
Once the builders stuck the fridge in a slide, there was no more roof vent so they added fans to artificially create the draft. Now, if they would have used good, quiet fan(s), all would be good but they use the cheapest available and that's not good, but then, they don't have to listen to noisy fans, they just assemble the units.
Even a roof vented fridge can benefit from added airflow, especially in the summer or when the sun is beating down on the side of the camper.
