What Matters Before You Choose an RV Air Conditioner Replacement
Key buying criteria so you get the right fit the first time.
Match the model number
A replacement part only fits if it matches your exact model. The Bonbo Shroud lists Penguin II model numbers like 641816C and the JIANBENKJ Fan Blade lists Brisk Air series. Read the model plate on your unit before ordering.
Repair or replace
A cracked shroud or fan blade costs a fraction of a new unit, while a failed compressor usually means replacement. The Dometic FreshJet 3 and FreshJet 5 are full units. Decide by what has failed.
Control compatibility
A new unit that works with your existing controls saves rewiring. The Dometic FreshJet 3 states backward compatibility with existing air returns and controls. Check your system.
Hardware included
Some parts leave out screws. The Bonbo Shroud does not include mounting hardware. Keep the old screws or buy new ones.
Ducted or non-ducted
Ducted and non-ducted systems use different grilles and boxes. The WEHOPE Grille is for ducted systems. Check your ceiling.
