When the front door stops opening, you are still open but nobody can tell. We work on every major automatic door brand and carry the parts that fail most, so most entrances are running again before we leave. We also handle storefront door repair and ADA door repair across Miami-Dade and Broward, with service in 6 states.
The questions we get most about automatic doors, answered from the field by Yuval, one of JDM's elite technicians.
On an automatic sliding door it is either the motor, the controller, or the sensor.
When a door starts opening randomly with nobody there, that is called ghosting, and it means the sensor has gone bad.
The customers who have us out twice a year for maintenance are not the ones calling us with an emergency.
That is called ghosting, and it means the sensor has failed. When a door starts opening randomly with nobody in front of it, the sensor is bad and it needs to be replaced with a new one. It is not something you adjust or reprogram your way out of.
The motor, the controller, or the sensor. Those three are the most popular problems we see. We check all three before quoting, because what you notice at the door does not always point at the part that actually failed.
We repair. If a part has failed, that part gets replaced, but the door itself we repair, and most of the time a door does not need changing at all. We are not going to sell you a new entrance because a controller went bad.
From Gal Cohen, Field Area Manager: "I've spent 15+ years on automatic door repair jobs, and our crews now run them across Florida, New York, Georgia, Colorado, Texas and South Carolina. Most repairs we handle wrap up in roughly 2 hours, same-day, and you can see the real before-and-afters in the photos and videos on this page."
An automatic door that stops working does not just inconvenience people, it becomes a safety problem and, in a lot of buildings, an accessibility one. JDM repairs automatic sliding and swing entries for retail stores, medical offices, hotels, restaurants, and multifamily lobbies, on every major brand.
Most calls come down to a handful of things. Activation and presence sensors drift out of alignment or fail outright, so the door opens on nothing or does not open at all. Drive belts stretch and slip. Carrier wheels and tracks wear until the panel binds. Operators and control boards fail. Breakout hardware stops latching. We diagnose the header, the drive train, the sensors, and the safety circuit as one system rather than swapping the first part that looks worn.
We service Stanley, Horton, Besam, Record, Nabco, and Dorma equipment, carry common operator and sensor parts on the truck, and test activation and reopen timing against the ANSI A156.10 requirements before we leave. You get a flat-rate quote before any work starts, and we tell you whether the operator is worth repairing or worth replacing only after we have seen it run.
★★★★★ Verified Google Reviews ★★★★★ · a month ago"After I made an appointment I decided I was going to try and do it myself. Michael FaceTimed me, walked me through what to do, then call back if I still needed him. An hour later I called him and he was at my house in 35 minutes. Some of the best service I've ever received from a contractor. He finished in two hours and went above and beyond. The same-day service was incredible. Absolute professionals."
★★★★★ · a year ago"After a couple of hiccups with getting our repair done by someone else, our technician Richard showed up on time (actually half an hour earlier than the appointment time). He was very polite and got the job done in the time he told us it would take. Our glass door now glides smoothly and is able to lock again. I highly recommend Richard, he represented his company very well. I will definitely consider using them in the future!"
★★★★★ · 9 months ago"David, thank you so much for taking the time to explain everything to us. He was so patient, and I appreciate him doing a clean and awesome job. He was respectful of my home and cleaned up after the work was complete. Now my door slides like new, quiet, and smooth. Again, thank you David."

We operate the door the way your customers do and watch where it actually goes wrong, then read any fault codes off the controller before opening anything up.
Header, drive train, sensors, and safety circuit get checked as one system, so we find the cause rather than the symptom that happens to be visible.
You get a flat-rate price before work starts. We tell you honestly whether the operator is worth repairing or has reached the end, and we never make that call before seeing the door run.
We set activation and reopen timing to ANSI A156.10, confirm the presence sensors hold the door, run the breakout, and walk you through what changed.
Call (954) 689-2155 or request an estimate online. We confirm flat-rate pricing upfront, with no hidden fees.
Our licensed tech arrives with common parts on the truck. Most automatic doors jobs are completed in a single visit.
We test the repair, walk you through the work, and make sure everything is running smoothly before we leave.
Two maintenance visits a year, and most of these calls never happen.
The customers we see twice a year for scheduled maintenance are not the ones calling with an emergency. Ask us what a maintenance schedule looks like for your doors.
The trade name for this is ghosting, and it means the sensor has gone bad. It is not a setting you can adjust your way out of. The sensor gets replaced, we confirm the door holds still with nobody in front of it, and the ghosting stops.
We trace it back through activation sensor, controller, and drive train to find where the signal or the motion actually stops, instead of swapping parts until something changes.
Stretched belts, worn carrier wheels, debris in the track, and failing operators all show up this way. We check the whole drive train before quoting.
Presence sensors that no longer hold the door for someone in the threshold are a real strike risk. We repair or replace them and test the reopen behavior before we leave.
Motors, gearboxes, and control boards do reach the end. We replace them with equipment matched to the door and the traffic it actually takes.
Emergency breakout has to swing out under force and latch again afterward. We rebuild the hardware so it does both, which matters for egress.
Carrier wheels, tracks, and guides wear. We service the running gear so the panel moves freely instead of forcing the operator to work against it.
Quarterly, semi-annual, or annual visits with documented inspection, adjustment, lubrication, and safety testing, to catch the drift before it becomes a service call.
⏱ Same-day service available based on capacity. Call to confirm dispatch.
We work on Stanley, Horton, Besam, Record, Nabco, and Dorma automatic doors, so you do not have to track down whoever installed the system years ago. If it slides or swings under power, we service it.
Sensors, drive belts, carriers, operators, control boards, and breakout hardware all interact. We diagnose them together, which is why our repairs tend to hold instead of coming back in a month.
Before we leave, we test activation and reopen timing against ANSI A156.10 and check that the presence sensors actually hold the door for someone standing in the threshold.
Common sensors, belts, carriers, and controllers ride with our technicians, so a lot of automatic door calls finish in one visit rather than waiting on an order.
A dead automatic entry at a store or clinic is a closed front door. Commercial calls get priority scheduling, and we run after-hours and weekend service when a failure stops your operation.
Scheduled service catches drifting sensors, stretched belts, and worn carriers before they strand a door open or shut. Every visit comes with a written record of what we checked and adjusted.
JDM services automatic doors across Florida, New York, Georgia, Colorado, Texas, and South Carolina, with commercial crews dispatched locally in each market.

Here are straight answers to the questions we hear most about automatic door repair.
Stanley, Horton, Besam, Record, Nabco, dormakaba, ASSA ABLOY, and GEZE, plus most of the older equipment those companies absorbed over the years. Stanley operators are the ones we see most in US retail and grocery. You do not need to know who installed yours. Send a photo of the header and we can usually identify the system before the truck rolls.
That is called ghosting, and it means the sensor has failed. When a door starts opening at random with nobody in front of it, the sensor is bad and needs replacing. Adjusting or reprogramming will not hold, because the part itself has gone.
Usually yes. Sourcing uncommon parts and discontinued hardware is a large part of what we do, and many older operators were absorbed by the manufacturers still trading today, so the parts have a current equivalent. Where a part genuinely no longer exists, the operator can normally be replaced without touching the panels or the framing, which costs a fraction of a new entrance.
It can be, and it is worth treating as urgent. A door that will not close leaves the building open and unconditioned. A door that closes too fast or too hard is a strike risk, especially for older people and children. Both usually trace to the operator, the closing force setting, or a presence sensor that is no longer holding the door.
Both, and which one depends on what the sensor is doing. A dirty lens or a sensitivity setting we correct on site. A sensor that has started ghosting, opening the door at random, has failed and gets replaced. We do not adjust a dead part and call it fixed.
Yes. When the operator has reached the end, we replace it and match the new unit to the door, the traffic it takes, and the activation setup already in place. We will not tell you it needs replacing before we have seen it run, because plenty of doors that look finished only need a carrier and a belt.
Yes. Scheduled maintenance is where automatic doors pay you back, because sensors drift and belts stretch gradually rather than failing all at once. We run quarterly, semi-annual, or annual visits with a written record of what was checked, adjusted, and replaced.
Yes. Our technicians are trained directly on the operators they service, and between Stanley, Horton, Besam, Record, Nabco, and Dorma that covers most of what is installed out there. If you can send a photo of the header before the visit, we will have the right parts on the truck instead of making it a two-trip job.
Commercial automatic door calls get priority scheduling, and we run same day or next day in most of our markets depending on capacity in your area. If the door is stuck open and the building is exposed, say so when you call and we will treat it as an emergency.
It depends on what failed. A sensor re-aim or a belt is at the low end, an operator or control board is at the high end, and a full operator replacement is a different conversation again. We quote flat-rate after seeing the door, so the number you approve is the number you pay.
