How to Identify a Carrier Rooftop Air Conditioner

Climb onto the top of your RV using the RV ladder or another ladder.

Examine the air-conditioning unit on the top of your RV. The unit will be located in the middle of your RV’s roof. It will be between 1 and 3 feet long and about 1 foot wide. It may bulge up to 1 foot tall, or it may only be 4 to 6 inches tall, depending on the model.

Locate the logo on the air-conditioning unit. If the logo is blue and says “Carrier” in white letters, it’s a Carrier air conditioner. If the logo is missing, look for an oblong oval indent in the plastic on the side of the unit where the logo used to be located.

Locate the model number of the air-conditioning unit. The model number will be next to the oval indentation on the unit where the logo was before it fell off. Write the number down.

Input the number into the Carrier product manual website (see Resources) to find a matching manual and click “Search.” If a manual shows up, the unit is a Carrier model. If the product number does not correspond to a Carrier air-conditioning unit, a manual will not show up on the website.
