MaxxAir MaxxFan Dome model and ventilation service prep

Use this when a MaxxFan Dome 3810 or 3812 bathroom or galley fan has lid, fan, light, exhaust, or model-identification symptoms.

Owner-safe checklist

• Record whether the fan is model 3810 or 3812, the installed room, lid position, exhaust behavior, switch response, and light behavior if equipped.
• Turn the fan off before ordinary surface cleaning or documenting a stuck lid or abnormal sound.
• Photograph owner-visible labels, control state, lid position, and visible symptom evidence from normal access.
• Use MaxxAir or qualified RV ventilation service for light failure, fan failure, stuck-lid behavior, water entry, or parts questions.
