RV Air Conditioner Parts & Accessories

What RV air conditioner brands and models do these accessories fit?

This collection covers replacement parts and accessories for the most common rooftop units on the road, including Coleman-Mach (Mach 1, Mach 3, Mach 8, Mach 15, Power Saver), Dometic (Brisk Air II, Penguin II, FreshJet), Furrion Chill, and Advent units. You'll find shrouds, control boards, capacitors, fan motors, gaskets, thermostats, and soft start kits. Always confirm your AC's model number and serial tag before ordering. If you need ceiling distribution hardware, see the Dometic non-ducted ceiling assembly or the Coleman ducted ceiling assembly collections.

Which Coleman Mach RV AC parts are most commonly replaced?

On Coleman-Mach units, the parts that fail most often are the run capacitor, the fan motor, the control board, and the roof compression gasket. For the Mach 15 (38204-066) and other 15,000 BTU models, a soft start kit is a frequent add-on because it reduces inrush current up to 75% and helps the unit start cleanly on 30-amp service or a generator. Power Saver HP owners should also check the Power Saver HP ducted ceiling assembly for matching distribution components.

Do you carry Dometic AC covers and shrouds?

Yes. We stock OEM and aftermarket shrouds for Dometic Brisk Air, Brisk Air II, Penguin, and Penguin II rooftop units in both white and polar white. Replacing a cracked or UV-faded shroud restores airflow geometry and protects the coil and fan assembly from weather damage. Measure your existing shroud's footprint and check the AC model number on the data plate before ordering, since Brisk and Penguin shrouds are not interchangeable.

How do I know which RV AC repair part I need?

Start at the model and serial tag on the rooftop unit itself, not the thermostat. That tag gives you the brand, BTU rating, and specific revision (for example, Mach 15 38204-066 versus an older 48204 series). From there, match the failure symptom to the component: no startup usually points to a capacitor or control board, weak airflow points to a fan motor or shroud, and water intrusion points to the roof gasket. For broader 12-volt and wiring diagnostics, our RV electronics collection covers the supporting systems. If you're unsure, text or call 817-984-1852 with your model number and we'll confirm the correct part.

What is shipping like on RV AC accessories?

Smaller parts (capacitors, boards, thermostats, gaskets, soft start kits) ship standard ground. Full shrouds and ceiling assemblies ship oversized due to dimensions. Orders over $100 qualify for free shipping on eligible items. Freight or oversized charges, when they apply, are noted on the individual product page so there are no surprises at checkout.
