MaxxAir MaxxFan Plus rain-sensor and remote service prep

Use this when a MaxxFan Plus 00-04500 owner needs product-page feature notes, rain-sensor behavior, remote details, or service-prep documentation.

Owner-safe checklist

Record fan model, lid position, fan speed, Auto mode, remote behavior, rain-sensor behavior, and any beep or response pattern.
Try only normal controls and remote-battery checks described for ordinary operation.
Stop using the fan if the lid, motor, remote, keypad, or rain sensor behaves abnormally after normal control checks.
Use MaxxAir or qualified RV ventilation service for repeated control symptoms, stuck lid behavior, abnormal motor behavior, or parts questions.
