This wall control is not universal for every Maxxair roof vent. It is commonly listed for MaxxFan Plus 4751KS / 4951KS and MaxxFan Deluxe 8751K / 8951K models. Before ordering, verify your fan model, original control panel, and cable connection style.
Before Starting: Disconnect 12V power to the roof vent fan before servicing control wiring or wall control components. Basic Replacement Steps: 1. Confirm Compatibility: Verify the fan model and compare the existing wall control to the replacement panel. 2. Disconnect Power: Turn off 12V power to help prevent shorts or control board damage. 3. Remove Old Panel: Carefully remove the existing wall control panel from its mounting location. 4. Disconnect Cable: Unplug the control cable from the old panel without damaging the connector or cable end. 5. Inspect Cable: Check the RJ-11 style connector and cable for corrosion, broken tabs, cuts, or pinched areas. 6. Connect New Panel: Plug the cable into the replacement wall control panel and seat the panel in place. 7. Restore Power: Turn 12V power back on and test fan on/off and vent open/close functions.
