The Challenger CLHM-591-00026 is the direct-replacement electrical control component for the Challenger lift it came off of — the genuine 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: CLHM-591-00026
• 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

Chasing an intermittent electrical fault is mostly hunting a loose or corroded connection with the power safely off — a lug, a terminal, a pitted contact. Tighten or replace what you find, then cycle the lift repeatedly to confirm the fault is gone. The full walkthrough lays out how to trace it in order. 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

Want to be sure before you buy? Pull the model and serial off your lift's plate and open our Challenger parts lookup to open the exploded parts breakdown for your model — find your part on the drawing and you know it fits. New to finding your model number? our guide to finding your model number covers it, or send a photo of the plate and we will read it 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

Since opening and locking out the control system is the real work, take care of the companion components while you are there. A relay, a switch, or worn wiring near the failure is best done in the same visit. We keep the right parts for your lift's voltage and phase — one call gets them matched.

Safety notes

Electrical faults on a lift range from annoying to dangerous, and the dangerous ones involve the safety circuits. Isolate power first, test for zero voltage, and restore the wiring exactly to the diagram. A chattering contactor or a jury-rigged switch is a call-us situation, not a run-it-and-see one.

Before you order

Before ordering an electrical part, note your lift's model, serial, and — critically — its voltage and phase, all of which are on the data plate. Single- and three-phase versions of the same lift take different components. Have the old part's markings ready and we will match the correct one for your control system.

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.
