The Rotary FA928 electrical control component is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7509-91, it is the genuine Rotary part — same part number, same fit, and same working specification as the one already on your lift. Ordering the Rotary electrical control component from us gets you the OEM piece that matches the lift, not an aftermarket knock-off that is close but not the same. Specifications Part number: ALS-7509-91 Brand: Rotary Type: Genuine OEM electrical control component Fits: A10i, A10i EH-1, A10i EH-2, A8i, A8i EH-1, A8i EH-2, S10i, S10i EH-1, S10i EH-2, S10i EH-4 Lift type: 2-post lift A small electrical fault left alone becomes a bigger, more expensive one. A loose lug that arcs will eventually burn the terminal, then the wire, then the component it feeds. A chattering contactor hammers the motor with partial voltage until the windings cook. Chasing down a hot connection or a pitted switch early is a cheap fix; letting it run until it melts something takes out the motor or the whole control box. The electrical side of a lift is what turns wall power into lifting motion: the disconnect and breaker feed a switch or push-button, which energizes a contactor, which sends power to the motor that spins the pump. Limit switches and safety cutoffs sit in the circuit to stop the lift at the top or if an overhead bar is hit. When the lift won't run, the fault is somewhere in that chain — and it's often electrical, not hydraulic. What lifts this electrical control component fits This electrical control component fits the lift models below. Click a model to open its visual parts breakdown — the exploded drawing with every part numbered, so you can confirm this is the right part for your exact lift before you order. A10I — see the exploded parts breakdown for this lift A8I — see the exploded parts breakdown for this lift S10I — see the exploded parts breakdown for this lift Replacing your electrical control component Replacing a contactor or switch means matching voltage and rating, killing power at the breaker, and landing the wires exactly as they came off — photograph the connections first. Then confirm the lift runs only while the button is held and stops the instant it's released. The step-by-step guide covers the wiring and the checks. Not sure on the procedure? Find your lift in our parts lookup or call and we will walk you through it. Find the right part for your lift Not certain this is the exact part your lift needs? Start with your lift's model and serial off the data plate, then open our Rotary parts lookup to see the visual parts breakdown for your model — the exploded drawing with every part numbered and priced. If your plate is missing or unreadable, our guide to finding your model number walks through where to find it, or send us a photo and we will identify the lift for you. Signs of an electrical fault Check the push-button or control switch for hold-to-run behavior and clean action. The lift should move only while the button is held and stop the instant it's released. A button that sticks, that runs on after release, or that needs several presses to make contact is worn or damaged. Because the control is a safety part, a switch that won't reliably stop the lift is a replace-now item. Parts commonly replaced at the same time Order the companions for an electrical repair by voltage and phase, not by guess. Control components share a circuit and a service life, so replacing the obvious failure while checking the related parts keeps the lift reliable. Give us the data-plate details and we will match the set. Safety notes Treat every lift electrical job as live until you have locked out and tested for zero voltage. Contactors, switches, and relays sit in the safety chain; get one wrong and an interlock stops protecting anyone. Follow the wiring diagram for your production year exactly, and hand off anything you are unsure of. Before you order Get the electrical order right by the numbers: model, serial, voltage, and phase, all from the data plate. Components differ between single- and three-phase builds of the same lift. Have the old part's ratings handy and we will confirm the right one before it ships. Confirm this is the right part before you order Lift manufacturers revise parts mid-production without changing the model name, so the same lift bought two years apart can take two different revisions of the same component. Before you order, find the model plate on the lift — on most 2-post lifts it rides on one of the columns at eye level, on 4-post lifts it is usually on a column or the power-unit side runway — and note the full model number and serial. The serial dates the lift to a production run, and that is what decides which revision fits. If the plate is painted over or missing, take a photo of the part you are replacing next to a tape measure and send it to us. Between the dimensions, the mounting pattern, and what lift it came off of, we can almost always identify the exact part before you spend money on the wrong one.
