Commercial Automatic Door Service: When to Repair, Replace & Inspect

Automatic doors are the hardest-working entrance in your building. A busy retail store, hospital, or hotel can cycle its front doors several thousand times a day — and every one of those cycles wears on sensors, belts, motors, and controllers. When an automatic door slows down, sticks, or stops sensing people, it's not just an inconvenience: it's an accessibility problem, a security gap, and in many cases a code-compliance issue.

This guide explains what commercial automatic door service actually covers, the warning signs that mean it's time to call, the AAADM inspection every automatic door needs, and how to decide between repair and replacement. If you already know your door needs attention, you can jump straight to our commercial automatic door service page or contact Paratec for a technician.

What "Automatic Door Service" Actually Covers

"Automatic doors" is a broad category, and each type has its own service needs:

• Automatic sliding doors — the most common commercial entrance; single-slide, bi-parting, or telescoping
• Automatic swing doors — low-energy ADA operators on existing swing doors, common on interior and secondary entrances
• Automatic and handicap door openers — push-plate and touchless ADA actuators (see our automatic & handicap doors page)
• Revolving and balanced doors — high-traffic lobbies and energy-conscious buildings
• Hermetic and ICU/patient-care doors — sealed, gasketed doors for healthcare environments

Service on any of these breaks down into three buckets: repair (fixing a failure), preventive maintenance (keeping it from failing), and inspection/certification (proving it's safe and compliant).

7 Signs Your Automatic Door Needs Service

Automatic doors rarely fail without warning. Watch for these red flags:

1. The door hesitates, stutters, or opens slowly. Usually a worn belt, failing motor, or dry rollers.
2. It doesn't detect people reliably. Faulty motion or presence sensors are both a nuisance and a serious safety hazard.
3. It closes too fast or "slams." Out-of-spec closing speed and force is the most common AAADM inspection failure — and an injury risk.
4. Unusual grinding, squealing, or clicking. Bearings, rollers, or the drive belt are wearing out.
5. The door reverses for no reason or stays stuck open. Sensor misalignment or controller faults.
6. Visible gaps, sagging, or dragging. Track or hanger wear that will accelerate if ignored.
7. The safety beams or guide rails are damaged. Any compromised safety component takes the door out of compliance immediately.

If you're seeing any of these, don't wait for a full failure that shuts your entrance down during business hours.

AAADM Inspection: The Compliance Piece Most Businesses Miss

Every powered pedestrian door in the U.S. is governed by ANSI/BHMA standards (A156.10 for full-energy sliding/swing doors, A156.19 for low-energy operators). Those standards require a daily safety check by the owner and an annual inspection by an AAADM-certified inspector.

AAADM (the American Association of Automatic Door Manufacturers) certification means the inspector is trained to verify:

• Opening and closing speeds are within spec
• Closing force won't injure a person
• Motion and presence sensors detect correctly across the full door path
• Signage, guide rails, and safety beams are present and functional

Skipping the annual inspection isn't just risky — it can void insurance coverage and create liability exposure if someone is injured. Paratec's technicians are AAADM-certified (#150572), so a single visit can both service the door and document its compliance.

Repair or Replace? How to Decide

Not every aging door needs replacement. Use this rule of thumb:

Repair makes sense when:

• The door is under ~10 years old and structurally sound
• Failures are isolated (a sensor, a belt, a controller)
• Parts are still available for the operator
• Total repair cost is well under half the price of replacement

Replacement makes sense when:

• The operator is obsolete and parts are discontinued
• You're facing repeated failures across multiple components
• The door no longer meets current ADA or energy-code requirements
• You're renovating the storefront or upgrading to touchless/energy-efficient operators

A good service provider will always quote the repair first and only recommend replacement when the math genuinely favors it.

What Automatic Door Service Costs

Pricing varies with door type, operator brand, and parts, but the factors that drive cost are consistent:

• Diagnosis / service call — the base visit
• Sensor or safety beam replacement — the most common repair
• Belt, roller, or bearing replacement — routine wear items
• Motor or gearbox — a larger repair, but still far below replacement
• Controller / logic board — brand-dependent, sometimes the deciding factor for replacement
• Full operator or new door install — the top of the range; see auto door installation

An annual AAADM inspection is inexpensive relative to the liability it protects against, and bundling it with a Planned Maintenance Program typically lowers your per-visit cost while giving you priority dispatch.

The Components That Fail Most Often

Understanding the anatomy of an automatic door helps you describe problems accurately when you call:

• Sensors (motion + presence): the #1 service item; misalignment, dirt, and age all degrade detection
• Drive belt: stretches and cracks over thousands of cycles
• Rollers and hangers: carry the door's weight; wear causes dragging and noise
• Motor and gearbox: the workhorse; usually fails gradually with noise and slowdown
• Control board: the "brain"; power surges from Florida's afternoon storms are a common killer
• Battery backup / lock: critical for egress and security during outages

Why Preventive Maintenance Pays for Itself

An automatic entrance that cycles thousands of times daily is a maintenance item, not a "set and forget" fixture. A preventive maintenance plan:

• Catches out-of-spec speed/force before it fails an inspection or injures someone
• Cleans and realigns sensors on a schedule
• Replaces wear items (belts, rollers) proactively
• Keeps documentation current for compliance and insurance
• Gives contract customers priority response when something does go wrong

For high-traffic and healthcare facilities especially, this is the difference between planned five-minute tune-ups and emergency downtime at your main entrance.

Why Choose a Commercial Specialist

Automatic doors sit at the intersection of accessibility law, life-safety code, and heavy mechanical wear. That's why they should be serviced by a commercial specialist, not a general handyman:

• AAADM-certified technicians who can inspect and certify, not just repair
• Access to major operator brands — the ability to source parts for what you actually have installed
• Experience across door types — sliding, swing, ICU/hermetic, and ADA operators
• 24/7 commercial dispatch so a stuck entrance doesn't close your business

At Paratec Door Solutions, we service and install commercial automatic doors across Florida, handle automatic & handicap door openers, and cover the rest of your facility too — from overhead and roll-up door repair to loading dock equipment — so one call covers every opening.

Automatic Door Service FAQs

How often do commercial automatic doors need to be serviced? At minimum, an AAADM-certified inspection once per year, plus an owner's daily safety check. High-traffic entrances (retail, healthcare, hospitality) benefit from quarterly or semi-annual preventive maintenance because of the sheer number of daily cycles.

What is an AAADM inspection and is it required? It's an annual safety inspection of a powered pedestrian door performed by an AAADM-certified technician, verifying speed, force, and sensor performance against ANSI/BHMA standards. While enforcement varies locally, the annual inspection is the recognized standard of care — and skipping it can create liability and insurance problems.

Why does my automatic door keep opening or reversing on its own? Usually a sensor issue — misaligned, dirty, or failing motion/presence sensors — or a controller fault. It's both an annoyance and a safety concern, so it should be diagnosed promptly.

Is it cheaper to repair or replace an automatic door? Repair is almost always cheaper for doors under ~10 years old with isolated failures and available parts. Replacement wins when the operator is obsolete, failures are repeated, or the door no longer meets ADA/energy code.

Do you install new automatic doors as well as repair them? Yes. Paratec handles full automatic sliding and swing door installation, ADA operator retrofits, and touchless upgrades in addition to repair and inspection.

Keep Your Entrance Moving

Your automatic doors are the first thing customers, patients, and employees touch — and one of the few building systems governed by both accessibility law and life-safety code. Regular service keeps them fast, safe, compliant, and out of the emergency-repair cycle.
