Dometic Blizzard NXT Air Conditioner Fan Motor Service Kit

Here's the short version. This is the genuine Dometic fan motor service kit for the Blizzard NXT line of rooftop RV air conditioners. If your unit runs the CCC2 or LCD control setup, this is the motor that spins both the interior blower wheel and the condenser fan up top. One motor, two jobs. When it goes, cold air stops reaching your living space and the unit can't shed heat off the roof.

As a service kit, it's built around the replacement fan motor itself, the part that actually wears out and needs swapping. It's the genuine Dometic component, not a generic stand-in, so the fit, the shaft, and the mounting all line up with your existing Blizzard NXT hardware. That's the whole point of buying the factory service kit instead of guessing at a substitute.

How do you know the fan motor is the problem? A few tells. The compressor kicks on but almost no air comes through the ceiling registers. You hear a low hum or buzz from the rooftop unit but the blower isn't spinning up. Sometimes the motor starts, runs for a bit, then trips out on thermal overload once it heats up. Or it grinds and rattles because the bearings are worn. Any of those, and the fan motor is usually the culprit. It's one of the most common failures on a rooftop RV air conditioner, especially on rigs that see dusty boondocking or years of full-season use. Heat and dust are hard on these motors.

Match the control system before you order. Dometic built the Blizzard NXT in a few control variants, and this kit is spec'd for the CCC2 and LCD setups. That matters. The fan motor has to work with the control board and thermostat that came with your unit, so the right service kit drops in and runs the way the factory intended. If you're not sure which control system you've got, check the model and serial tag on the air conditioner, usually up on the roof or printed inside the ceiling assembly.

Installing it is within reach for a handy RV owner, but respect the power. Kill the shore power and the breaker to the air conditioner before you touch anything up top. From there it's pulling the rooftop shroud, disconnecting the old motor's wiring, unbolting it from the blower housing, and reversing the process with the new one. Take a photo of the wiring before you unplug it. If you're not comfortable on the roof or working around 120-volt wiring, this is an easy job for any RV service tech, and the kit is exactly what they'll want on the bench.

This is the repair that saves you from replacing a whole rooftop unit. A new air conditioner is a big-ticket item and a real project to swap. A fan motor is a fraction of that, and if the compressor and coils are still healthy, there's no reason to scrap a good unit over one worn motor. We see plenty of owners get many more seasons out of their NXT this way. It's the smart, budget-friendly fix. And you're back up and running in an afternoon instead of waiting on a full-unit order and a bigger install.

One thing to be clear on. This is a service part, not the complete air conditioner. It's the fan motor kit for Blizzard NXT units with CCC2 or LCD controls, nothing more, nothing less. If you're chasing a different symptom, like a bad capacitor, a failed control board, or a compressor that won't start, that's a different part. But if you've traced the trouble to the fan motor, this genuine Dometic kit is the right call. Order it, get up on the roof, and get your coach cooling again.
