The Genie 35219A.S Top Gear Housing is a genuine OEM replacement component for select Genie garage door openers. Positioned within the opener’s powerhead, this housing supports and aligns the top drive gear so the motor can transfer motion smoothly to the chain, belt, or screw mechanism. Replacing a cracked or worn top gear housing helps restore proper operation, reduce excessive noise, and prevent premature wear of the gear train. This part is identified in Genie parts lists as 35219A.S (sometimes shown as 35219A S) and is intended as a like-for-like replacement where that exact number is specified.
Use this Genie replacement part when servicing the drive assembly on compatible residential garage door openers. Installation typically requires removing the opener cover, accessing the gear train, and transferring or re-seating existing drive components within the new housing; always disconnect power and disengage the door before service, and follow the opener’s service manual for torque, alignment, and lubrication guidance. No programming is associated with the housing itself, though you may need to verify travel limits and safe door balance after reassembly. Verify compatibility by matching your opener’s model and illustrated parts list to part number 35219A.S to ensure a direct fit for your repair or upgrade.
