MAXXFAN Repair Parts: Fan vs Lid Motor, Screen & Lift Arm

A MAXXFAN may stop moving air even when its roof lid still opens. Or the fan can run normally while the lid refuses to lift. Those faults involve different components. This repair-parts guide identifies the fan-drive system, lid-opening mechanism, screen, exterior lid and interior controls by exact MaxxAir part number, then links to corresponding UsedRVParts listings.

Which part are you trying to identify?

Fan does not move airStart with the fan blade and fan-drive motor circuit. The 10-20258KS is a blade, not a motor. Fan-drive motors are model and production-date sensitive; identify the exact motor before buying.
Lid does not rise or closeCheck the manual lift arm and operator on manual models. Powered models can also have a distinct 10-20270 lid-lift motor. This motor does not spin the ventilation blade.
Damaged cover or interior partsFor selected Deluxe vents compare 05-30510 white or 05-30520 smoke lids. The 05-30925 is a screen, while 05-20226K is the control plate.

Follow the parts through the roof-vent assembly

These groups are a simplified parts-identification reference, not an exploded manufacturer diagram or a wiring schematic. Different MAXXFAN series and production revisions use different control boards and lift assemblies.

Two motors, two jobs: MAXXFAN 10-20270 is a roof-lid lift motor used in selected powered-opening units. A fan-drive motor is a different part. Replacing one will not correct a fault in the other. Identify the fitted fan by model and serial number.

Confirm model and revision before selecting a service part

  1. Read the MAXXFAN model and serial labels. Plus 4000K–4951K units and Deluxe 5100K–8951K units use different lid arrangements, controls and diagrams. Do not treat family names alone as a service-parts cross-reference.
  2. Inspect manual versus powered lid. A manual knob and drive shaft are not interchangeable with a powered lift motor. Match the manufacturer's exploded-parts drawing to the exact model.
  3. Identify the component rather than a nearby part. The 05-20226K plate, 05-30925 round screen, 10-21299K keypad and printed circuit boards are distinct items.
  4. Check colour and mounting. White and smoke lids are separate MPNs. Verify lid family, hinge arrangement, lift-arm connection and the original part's markings.
  5. Check item condition individually. UsedRVParts carries varied inventory; a listing's current condition and availability are shown on that product page, not implied by its inclusion in this guide.

Replacement parts and exact MPN listings

For a complete model drawing, start with the roof-vent and fan model finder, MAXXFAN Plus 04500K drawing, MAXXFAN Plus 04002K guide or Deluxe 5301K/6401K parts guide. Select the service drawing that matches the label on your fan.
