Mighty Mule Gate Motor Replacement: The North Hollywood Owner’s Guide
Most Mighty Mule gate motor replacements in North Hollywood run between $540 and $980 installed, depending on whether you need the full motor assembly or just the control board and arm. We stock Mighty Mule compatible motors and parts on our trucks, so most replacements happen same-day when the gate is stuck open. It’s the number one call we get from homeowners whose gate worked fine for years, then one morning just hums and doesn’t move, or opens halfway and stops.
Which Mighty Mule Models This Applies To
This page covers the Mighty Mule swing-gate line: the MM260, MM360, MM371W, MM372W, MM571W, MM572W, and the newer MM600 and MM700 series. The compatibility gotcha we see all the time in North Hollywood is this: the MM271 and MM272 are discontinued, and owners try to mate a used arm to a new board without realizing the boards changed impedance between series, so the gate creeps two inches every cycle. If your plate shows anything in the MM200 range, we replace the motor as a paired unit rather than mixing generations.
For OEM versus aftermarket: Mighty Mule’s OEM motors are built by GTO Access Systems, and the aftermarket equivalents we carry are direct-fit, not universal. The difference that matters in the sun here is the capacitor grade. The OEM capacitor is rated for 10,000 cycles; the aftermarket units we install are rated for the same, but some budget ones sold online are rated for 5,000. In North Hollywood’s hot summers, a cheap capacitor bakes and the motor stalls mid-swing within six months.
Signs Your Mighty Mule Gate Motor Replacement Is Failing

- The gate hums but doesn’t move. Usually the start capacitor or the motor’s internal clutch has failed. The control board is still sending power, but there’s not enough torque to swing the gate. A failed capacitor will often swell at the top; we can typically swap it the same visit.
- The gate opens halfway and reverses. This is the auto-reverse sensing an obstruction that doesn’t exist, almost always a control board that’s lost calibration. It’s more common on gates that see salty air from being driven near the 101, and the fix on a Mighty Mule is typically a limit re-set or board replacement.
- Intermittent operation on the remote only. If the keypad works fine but the remote is flaky, the receiver is usually fine; it’s the motor’s built-in antenna or the remote battery. Before you replace the motor, we always check battery voltage at the receiver; those coin cells fail fast in heat.
- The gate is slower than it used to be. A slow gate is usually a tired capacitor or a battery that’s lost capacity on a solar unit. Mighty Mule’s solar models really do degrade faster on North Hollywood’s south-facing driveways, because the battery sits under a black housing in direct sun all afternoon.
- Error codes repeating. On the MM371W and above, a “2” blink or “3” blink that won’t clear usually points to a bad hall sensor inside the motor. We read the code, replace the sensor or motor, and photograph the new position for the record.

AfterReplacement Cost & What’s Included
In North Hollywood, a complete Mighty Mule motor replacement including the matched arm, board, and labor typically lands between $540 and $980. The spread is driven by which series you’re on; MM260 and MM360 parts are the most common and sit at the low end, while the MM700 series with its integrated battery management runs higher. If your existing gate arm and bracket are intact and it’s only the board or capacitor, that repair alone is often under $300.
You get a written price before we touch the gate, a documented photo record of exactly what we found and what we installed, and a full year to call us back under the 365-Day Done Right Promise if anything’s not right. We don’t charge you an estimate fee, and we never hand you a verbal number and then invoice higher. The price we write down is the price you pay.
DIY or Call Us?

The honest split: you can safely check the power source, the battery voltage if you have a solar unit, and physically confirm the arm isn’t bound by debris or a misaligned hinge. Those things cost you nothing. What you shouldn’t do is open the motor housing and start testing a live capacitor: a charged start capacitor can hold 360 volts, enough to zing you. We’ve taken over several North Hollywood jobs where the homeowner diagnosed and bought the wrong part online, then paid us anyway to undo the damage. If your gate has 12-volt battery or solar components, those are low voltage and safe to inspect; line-voltage motors are not.
If you’re not sure, call us at (213) 566-1045 and describe the symptom. We’ll tell you over the phone if it’s a quick check or a replacement, and we’ll only come out if it’s worth the trip.
FAQs
The control board and motor on a Mighty Mule swing gate typically last 7 to 10 years in North Hollywood’s climate, with the capacitor being the first wear item at roughly 5 to 6 years if the gate sees direct afternoon sun. We see many MM371W units from 2016 and 2017 still on original boards. The single biggest lifespan killer here is a sagging hinge that forces the motor to work against misalignment every cycle. Call (213) 566-1045 if you’d like us to check yours before it fails.
Yes, on most models. The most common repairable failures are the capacitor, the limit switches, and the receiver board. We carry those parts on the truck and can often repair a Mighty Mule motor the same day you call. The only time we recommend full replacement is when the motor’s internal hall sensor has failed or the unit is 12+ years old and parts are discontinued, like the MM271. We’ll tell you which one applies to your gate before any work starts.
Most Mighty Mule motor replacements in North Hollywood take 60 to 90 minutes including the limit re-set, re-balancing the gate, and photographing the finished work. If we also need to weld or replace a bent gate bracket, add 30 minutes. You’ll have a written record of the part numbers installed and the gate’s final travel settings before we leave.
Yes. We stock parts for LiftMaster, Ghost Controls, DoorKing, and several other automation brands in addition to Mighty Mule. If your neighbor’s gate uses a different brand, we can service that too. Vance Gate Repair is an independent service company, not affiliated with Mighty Mule, and we work on what’s already on the property rather than steering every job toward one manufacturer. Call (213) 566-1045 for an exact price on what you need.
