The Rotary N413-1 electrical control component is the direct replacement for the Rotary lift it came off of. Cross-referenced as ALS-7538-54, 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-7538-54
- Brand: Rotary
- Type: Genuine OEM electrical control component
- Fits: SPO12 EH-1, SPO12 EH-2, SPOA7, SPOA9
- Lift type: 2-post lift
The electrical system feeds the motor, and the motor drives the pump — so an electrical fault often looks like a hydraulic one and vice versa. A lift that won't rise might be a dead capacitor, a burned contactor, a tripped limit switch, or a pump that's seized and stalling the motor. The wiring, the switch, the contactor, the motor, and the pump are one chain; trace it in order instead of guessing.
The control gear — switch, contactor, overload, limit switches — is what makes the lift safe to operate, not just able to run. The button has to be hold-to-run so the lift stops when you let go; the overload has to trip before the motor cooks; the limit switch has to cut power at full height. When a control part fails, the risk isn't only a lift that won't work — it's a lift that won't stop when it should.

Replacing your electrical control component
Servicing the safety cutouts — limit switch, overhead shut-off, overload — is about confirming the lift stops on its own when it's supposed to, not just that it runs. Replace the failed device, then test each cutout deliberately. Since these are what make the lift safe to operate, the step-by-step 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 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
Test the safety cutouts, don't just assume they work. Run the lift to full height and confirm the up-limit switch cuts power where it should. If the lift has an overhead shut-off bar, trip it and confirm the lift stops. A limit switch that's bent, corroded, or bypassed is a safety defect — the lift has to stop on its own at the top and when the bar is hit.
Parts commonly replaced at the same time
Plan the electrical repair as a circuit, not a single part. The components around a failure often share its age, and doing them together while power is off is safer and cheaper than repeat visits. Give us your lift's configuration and we will assemble the matched set.
Safety notes
Before the cover comes off, the power comes off — and gets verified off. Lift controls tie the motor, the interlocks, and the shutoff together, so a careless connection can make a lift move when it should not. Match the diagram, respect the safety circuit, and get help on anything outside your comfort zone.
Before you order
Ordering tip: electrical components are specific to the lift's voltage and phase, so read the plate before you buy. A 208-230V single-phase lift and a three-phase version of the same model do not share the same contactor or motor. Send the markings off the old part and we will confirm the match.
Check your lift's serial before ordering
The most common reason a lift part comes back is not a defect — it is a revision mismatch. Manufacturers change sub-parts between production runs while keeping the same lift model name, so "it fits my lift model" is not always enough. The model plate carries the serial number that pins your lift to a specific run, and that is the number that settles which version of this part belongs on your lift.
Can't find the plate? Measure the old part — overall length, bolt-hole spacing, thread size on anything threaded — and photograph it from a couple of angles. Send that with your lift's brand and rough age and we will match it against the parts breakdowns we service from every week.
Why buy your Rotary electrical control component from Auto Lift Services
We install, inspect, and repair Rotary lifts every week — the ALS-7538-54 is a part we handle in the shop, not a random SKU we drop-ship. The phone answers if you have a question mid-install — call 800-674-9302 — and every part ships genuine, no aftermarket substitution unless you ask for it.
About this n413 overhead limit
Sourcing the correct n413 overhead limit is not the spot a shop wants to gamble. This piece sits inside a load path the lift manufacturer engineered to specific tolerances, and a substitute that looks close but is off by even a small margin can transfer load onto a neighboring component that was not designed for it. We stock this exact part to the OEM specification the original manufacturer publishes, which is why techs who have been through a bad aftermarket cycle keep coming back to us for the same replacement whenever their next need comes up.
Technical specification & installation notes
Technical specification matches the OEM published dimensions to within manufacturing tolerance. When a shop installs the n413 overhead limit correctly, the lift returns to factory-rated performance immediately — no break-in period, no cycle-count adjustment required. The lift's safety systems (mechanical locks, hydraulic pressure relief, and electrical interlocks) treat a correctly-installed replacement exactly as they would treat a factory-original component during initial commissioning. That parity is what lets us honor warranty coverage without asking for the lift's full operating history.
Shipping & ordering
Freight covers the continental United States on all standard orders. We ship UPS or FedEx ground for parts under 30 lb; heavier assemblies quote at published carrier rates. International orders on the n413 overhead limit require a freight quote — email dimensions, weight, and destination country to [email protected] and we return a rate within one business day. Alaska, Hawaii, and US territories quote at published rates and typically take five to ten business days depending on carrier and destination.
Warranty coverage
Return policy on the n413 overhead limit follows our store-wide standard: all parts sales are final; exchanges only if the piece arrives defective. In the case of a defective delivery, ship the failed piece back to us at your cost, we verify the defect on receipt, and ship a replacement at ours. Wrong-item deliveries where we made the shipping error follow a different path — we reimburse the return shipping cost and cover freight on the correct part. Contact [email protected] with the order number to start either process.
Cross-reference & fitment
Cross-reference on the n413 overhead limit is straightforward: match the OEM part number from the lift's parts breakdown against the number on your original invoice. If the numbers match, the component fits. If your lift's parts breakdown lists a superseded or alternate number, we accept the superseded value on the phone as confirmation of fit. When a manufacturer has issued a running change during production, we track the change in our catalog so ordering by the older number automatically pulls the current-spec replacement.
Questions about the n413 overhead limit? Call our parts desk at 800-674-9302 or email [email protected]. We ship nationwide from our Iowa warehouse and answer fitment questions within one business day.
