Challenger 591-00142 E-stop Switch
The Challenger 591-00142 electrical control component is the direct replacement for the Challenger lift it came off of. This is the genuine Challenger part — same fit and same work ing specification as the one already on your lift. Ordering the Challenger 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: 591-00142 Brand: Challenger Type: Genuine OEM electrical control component The one spec you cannot get wrong on lift electrics is voltage. A 110-volt motor and a 220-volt motor are not interchangeable, and neither are their contactors and overloads. Single-phase versus three-phase matters just as much. Read the data tag on the motor and match voltage, phase, and horsepower exactly — the wrong one either won't run, runs weak, or burns up the first time it's asked to lift. Electrical parts fail by heat and by contacts. A push-button's contacts pit and stop making a clean connection; a contactor's points burn and weld or chatter; a wire lug loosens, arcs, and cooks. Motors fail on windings, bearings, or a start capacitor. The tells are a lift that runs intermittently, won't start, trips the breaker, hums without turning, or greets you with the smell of hot varnish.

From there it's methodical — trace the fault to the switch, contactor, motor, or a loose connection, replace the failed part, and test that the lift runs and stops correctly. Since it's live power, the full procedure is worth following start to finish. 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 Challenger 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 The electrical triage list: dead lift — check breaker, disconnect, and incoming voltage first; intermittent — hunt a loose or corroded connection; hums but won't turn — capacitor or seized pump; trips the overload — motor or binding pump drawing high current; burnt smell — find the overheated point before running again; chattering contactor — low coil voltage or worn points. Power off before you probe or tighten anything. Parts commonly replaced at the same time When you are in the control system, look at the parts around the failure: the relay near a dead contactor, the switch on a circuit that keeps dropping out. Doing the related components together while power is locked out saves a second service. We will pull the right versions for your lift's configuration. Safety notes Power off, verified off, before the panel opens. The electrical side of a lift controls the parts that make it safe — the overhead cutoff, the interlocks, the motor — so a wrong connection is not just a dead lift, it can be an unsafe one. Work the circuit cold, and if the wiring does not match the diagram, get help rather than guessing. Before you order Electrical fit comes down to voltage and phase, so confirm both off the plate before ordering, along with model and serial. The same lift model can ship in more than one electrical configuration. Not sure what you are looking at? Photograph the old part's label and we will identify the correct replacement. Ordering the right revision Before this goes in the cart, grab two things off your lift: the model number and the serial number, both on the manufacturer's plate. The serial matters more than most people expect — lift makers revise components between production runs without renaming the lift, and the run your serial falls in determines which revision of this part is correct. If you are working from a failed part rather than a plate, measure what you have and photograph how it mounts. Send that to us along with the lift brand, and we will check it against the same parts breakdowns our own techs use in the field before you commit to the order.
