The Challenger 591-00012 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 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: 591-00012
• Brand: Challenger
• Type: Genuine OEM electrical control component

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.

Replacing your electrical control component

Most lift electrical work follows the same order: verify power is off, trace the circuit from source to motor, replace the failed part, then power up and test both operation and the safety stops. Guessing at where in the chain the fault lives wastes time and risks the wrong part. For that reason the full procedure is worth reading first. 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

The surest way to get the right part is to work from your lift's own breakdown. open our Challenger parts lookup, choose your model, and every part is mapped on the drawing with its number and price. If you cannot find the model plate, our guide to finding your model number explains where each lift type hides it, and our phone line is open if you want a hand.

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

Electrical faults often involve more than one component — a failed contactor can take a relay or a switch with it, and worn wiring shows up alongside. While the panel is open, check the companions so you are not back in there next week. Tell us your lift's voltage and phase and we will match the related parts.

Safety notes

Isolate the lift from power before you touch any electrical component — lock the disconnect out if the shop has one. Lift control circuits mix line voltage with low-voltage safety inputs, and a miswire can defeat an overhead shutoff or a lock. If you are not confident on the control system, stop and call for help before something moves unexpectedly.

Before you order

Have the data plate in front of you — model, serial, voltage, phase — before ordering electrical parts. These details decide which relay, switch, or motor fits, and getting them wrong means a return. If the markings on the old component are readable, share them and we will match exactly.

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.
