The Challenger 31121 electrical control component is the direct replacement for the Challenger lift it came off of. Cross-referenced as ALS-7226-87, it is the genuine Challenger part — same part number, same fit, and same working 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: ALS-7226-87 Brand: Challenger Type: Genuine OEM electrical control component A lift motor tells you it's failing before it quits. It hums but won't turn (a dead start capacitor or a seized pump), it starts slow or weak (worn windings or low voltage), it trips the overload after a minute (drawing too much current), or it runs hot and smells of scorched varnish (insulation breaking down). A motor that's tripping, humming, or smelling hot is on its way out. Electrical wear is about cycles and connections. Every press of the up button makes and breaks a contactor's points, and those points erode a little each time until they no longer pass full current. Loose connections aren't age so much as vibration and heat working a lug loose over the years. A motor's bearings and start capacitor are the parts that clock hours; the switchgear wears by count of starts. Related parts for this lift The parts below are commonly ordered alongside this one — cables, sheaves, seals, and hardware wear on similar schedules, and most repairs go faster when the whole set is done in one visit. Limit Switch Cord - Challenger - 31167 Switch Tube - Challenger - 36026 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 Landed here but not 100% sure it is your part? Grab the model and serial from the data plate and open our Challenger parts lookup for the visual breakdown — the manufacturer-style drawing with every item numbered so you can match yours exactly. Plate missing? our guide to finding your model number helps, and we identify lifts from photos every week if you would rather ask. Signs of an electrical fault Start at the source and work in. Confirm the breaker is on and not tripped, the disconnect is closed, and voltage is actually present at the lift with a meter — don't assume. A lift that's completely dead is usually upstream: a tripped breaker, a blown fuse, an open disconnect, or a loose feed. Verify power arrives before you condemn anything on the lift itself. 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. Not sure this fits? Here's how to check Pull the number off your lift's model plate first — model and serial both. Manufacturers run mid-cycle revisions that keep the model name but change hardware, so two lifts with the same name on the column can take different parts. The serial is what removes the guesswork. Second check: compare the old part against this listing before you order. Length, mounting pattern, and thread sizes tell most of the story. If anything doesn't line up, or if the old part is too worn or broken to measure, call us with photos — we work on these lifts every week and can usually confirm fit from a picture and the lift's serial faster than you can dig through a parts diagram.
