Wasps, mud daubers, birds, and rodents can enter your RV refrigerator vents and build nests that block airflow, damage the cooling unit, or create fire hazards. The Camco 42153 installs directly over the 27-1/2" louver openings on Norcold refrigerator vents, creating a physical barrier that keeps pests out without restricting the ventilation your fridge depends on. Sold in a pack of 3 so you can cover all vent openings in one order.
Norcold absorption refrigerators rely on open vent louvers along the exterior wall of your RV to dissipate heat. Those same openings are an easy entry point for insects -- especially mud dauber wasps -- which build clay nests inside the vent cavity. A blocked vent leads to overheating, poor cooling performance, and in some cases irreversible damage to the ammonia-based cooling unit. The Camco 42153 screen is a low-cost, easy-to-install fix for a problem that costs RV owners thousands in repair bills every year.
The screen is sized specifically for the 27-1/2" louver opening found on many standard Norcold refrigerator vent covers. If your vent has a different louver length, Camco offers additional sizes in the same product family -- verify your measurement before ordering.
Corrosion-resistant stainless steel construction stands up to outdoor exposure, humidity, and road grime without rusting or degrading.
Dimensioned at 27-1/2" L x 1-5/16" W to match the louver openings on compatible Norcold refrigerator vent covers exactly.
Three screens included per package -- enough to cover the multiple louver slots on a full-size Norcold vent panel in a single purchase.
Fine mesh blocks insects and debris while maintaining the airflow required for safe absorption refrigerator operation.
Mud dauber wasps are the most common pest to target RV refrigerator vents. They construct dense clay tubes inside vent cavities within hours of the RV sitting idle. These nests do not just block airflow -- they can also contact the boiler tube or burner assembly on propane-mode refrigerators, creating a potential fire risk. Prevention with a properly sized screen is far simpler than nest removal and far cheaper than cooling unit replacement.
The Camco 42153 screens are designed to slide or press into the louver slots on the existing Norcold vent cover. No tools or adhesive are required in most installations. The key step is confirming that your vent cover has louver openings that measure 27-1/2" in length before purchase. Remove and clean out any existing debris or nests before installing the new screens.
