Genie PMX300-IC and PMX500-IC Replacement Parts
Genuine Genie replacement parts for ProMax models PMX300IC, PMX300IC/A, PMX300IC/B, PMX500/IC, PMX500IC/A, PMX500IC/B and IC250. Each section below has its own diagram directly above its own table. Find your part on the diagram, match the reference number in the table beneath it, then click the part number to order. These reference numbers are the ones printed on the Genie parts drawing.
This opener shipped with either a channel rail or a T-style rail. Check which one you have before ordering rail parts — they share door arms and brackets but use different carriages, pulleys and sprockets. Remotes, keypads, wall controls and Safe-T-Beam safety sensors are listed in the last section.
