Our service centre specialises in professional diagnostics and comprehensive repair of high-speed doors.
One of di services we offer na Repair of high-speed door drives.

We dey carry out repairs for service companies, door manufacturers’ service teams
and maintenance departments of different end customers,
like industrial companies and discount store chains.

Every maintenance manager for an industrial facility,
wey don experience high-speed door drive failure, knows
say to replace a high-speed door drive
costs from about 1/3 to 1/2 of di value of a new door.

To meet our customers’ needs, we develop a door drive refurbishment department for our service centre, significantly reducing di cost of one of di most expensive repairs.

Hundreds of companies from all over di world dey use our services. Di map above (as of 05-2026) show only di locations of service companies wey we dey work with.

We fit divide di faults into three groups:

Group I – damage wey happen because dem use controller without frequency inverter.
Controllers wey no get soft-start and gradual braking functions dey damage di gearmotor mechanisms because di drive dey start and stop sharply.
Example of dis type of controller: TST WU.

Group II – damage wey happen because dem dey use di door very frequently, or because di drive dey under heavy load due to di door size and di heavy door curtain.

Group III – damage wey happen because of harsh environmental conditions, like high humidity, salt exposure or low operating temperature.

If dem no maintain di high-speed door, di force wey dem need to drive di shaft go increase -> dis still dey make di drive wear out faster and reduce how long e go last.

FAQ – questions wey people dey ask most:

1) Wetin di repair involve?

• First, we dey check di condition of di drive as e reach us.
• We dey take photographs of di mechanical damage.

• We dey check whether di encoder, di motor electromagnetic brake and di brake rectifier dey work properly.
• We dey measure di winding impedance and check whether current dey leak from di windings to ground.
• We dey use hand crank check whether di drive dey move or e dey jam for any point.
• We dey remove di motor and check whether gear oil don enter di rotor chamber.
• We dey remove one of di seals and check di oil condition – we dey check whether worn bearings and gears don leave metal particles inside, and how much dey there.

• We dey dismantle di drive completely and clean all di mechanical components.

• We dey check di condition of all components wey dey responsible for di safe operation of di drive -> den we dey decide whether refurbishment dey possible and whether we fit make di equipment fully functional again.
• We dey check and remove grooves for di sealing surfaces.
• When necessary, we dey repair or manufacture components using CNC technology.
• Once all di components don ready for reassembly, we dey put di drive back together with brand-new, highest-grade bearings (we prefer SNR, NTN and FAG) and new seals, den fill am with di correct gear oil.

• Di last stage na repeated-cycle tests after repair, using di correct frequency-inverter controller wey ensure say di drive dey run smoothly.

2) Una dey test di drive after repair?

YES – every drive dey undergo repeated-cycle tests while e dey run with di correct frequency-inverter controller, configured for dat drive. We still build special test bench where we dey simulate drive load wey close to di actual load for di equipment. During testing, di drive dey complete from several hundred to as many as 2 thousand cycles. Since we dey give warranty for our services, we must dey 100% sure say di repaired equipment dey fully functional.

3) Person fit predict fault before di door stop completely?

YES – but regular maintenance dey necessary (for example, once a year), so di service team wey dey attend to una fit notice signs of damage.

Wetin you suppose look out for? -> Strange metallic sounds, grinding noise for di gearbox and gear oil leaks.

From our experience refurbishing hundreds of controllers and drives, we estimate say for doors wey dey work without counterweight system, drives dey start to develop faults after dem pass 400 000 cycles. Our service team strongly recommends say dem must refurbish di high-speed door drive when e reach 400-500 thousand cycles.

If di door very large or e dey work for harsh environmental conditions, di drive no go last as long. For doors with counterweight system, drives fit complete as many as 1,5 million cycles and still dey in good condition. But nobody fit take dis figures as guaranteed, because plenty factors fit reduce di expected operational life. Some of dem na:

• incorrect drive installation,
• incorrect parameter settings,
• wey no follow di drive manufacturer’s recommendations,
• or door maintenance wey dem no do professionally, or no maintenance at all.

4) Person fit prevent drive failure?

E depend on which group di damage belong to and how far e don progress.

Group I
(damage wey happen because dem use contactor controller, meaning controller without frequency inverter)

E always possible to replace di controller with more advanced model wey get frequency inverter for soft start.
To explain di difference between contactor controller and frequency-inverter controller better, we prepare special article: https://doors.support/poradnik/poradnik/roznice-pomiedzy-sterownikiem-stycznikowym-a-sterownikiem-falownikowym-wplyw-na-zuzycie-napedow-bram-szybkobieznych

We still dey offer used, fully functional controllers wey don undergo complete refurbishment. Each one get one-year warranty and free support for commissioning and fault diagnosis during use.
See our offer for refurbished controllers: https://doors.support/oferta/sterowniki

Di gallery below show examples of damage to drive components wey work with start/stop contactor controllers, without frequency inverter for soft start.

Group II 
(damage wey happen because dem dey use di door very frequently or because di drive dey under heavy load)

• Dem need to remove di door drive and send am to us for complete overhaul.
• Most times, we dey do dis kind refurbishment during factory production shutdowns, because di repair process itself dey take several days.

Group III 
(damage wey happen because of harsh environmental conditions)

• Dem fit often remove di effects of di environment where di door dey work on site and prepare di drive to work for another year. We recommend say dem do dis kind work during di yearly door maintenance.

No matter which fault group your high-speed door drive belong to, remember say if your facility get at least several high-speed roll-up doors, wey often use di same type of drive, we fit offer sale of refurbished door drive. If you get one extra unit, you fit replace di drive for one door and send di removed unit to us for repair -> dis go allow you start regular equipment refurbishment without pressure. If you get any questions about di technical possibilities, contact us and you go receive expert help.

5) Wetin be di signs of drive problems?

Problems wey we fit see:

• di door dey slow down at certain points while e dey rise; for example, e dey open smoothly 100cm, slow down for di section 20cm, den continue at di previous speed,
• oil dey leak from di drive.

Problems wey we fit hear:

• irregular metallic sound (sometimes squealing) wey dey come from di drive throughout di door operating cycles,
• loud bang when di door start to open; abeg no confuse dis with di sound of di drive electromagnetic brake, wey still dey make sound when di drive start to work.

Problems wey we fit feel:

• motor temperature too high,
• temperature around 80 degrees Celsius don already dey concerning (we recommend measuring am with thermal imaging camera).

Problems wey don reach more advanced stage:

• di door dey stop at unpredictable times, and controllers like:
  Hörmann BK 150 FU E H / Efaflex EFACON / TST FUS / TST FUE / TST FUE2 / FUE3 and similar ones dey display messages:
  F030 – following error,
  F410, F440, F510 – motor overcurrent,
  F519 – starting problems, overcurrent,
• when dem switch on di controller power, di overcurrent circuit breaker for di electrical distribution board dey trip (dis mean say di drive don get damage wey later damage di controller too; for dis case, send di drive together with di controller to us).

6) Repair worth am?

YES – if e no worth am, dis page for our website no for dey.
On average, refurbishment cost 2-3 times less than new drive. We dey send quotation by email after we receive your enquiry.

7) Una fit fix every fault?

• NO – if dem continue to use di drive for many months despite clear signs say e no dey work properly, e fit be say nobody fit save am. For dis situation, we no dey charge for workshop diagnosis.

• We no dey do any repair wey fit affect safety when person dey use di door -> you fit dey sure say di drive wey we refurbish dey work well and fit serve you for many more years without fault.

8) Na only high-speed door drives una dey repair?

95% of di drives wey we dey repair na devices wey work for high-speed doors with controllers wey get soft start (with frequency converter / frequency inverter).

If you get faulty drive for big industrial rolling door or drive wey dem join with controller for sectional door, like Hörmann WA400FU -> we fit still help you fully repair di faults for these devices.

Because these repairs need plenty work, we no dey offer refurbishment for simple, cheap door devices wey work with relay controllers (start <-> stop).

9) How I go take sure say di drive no go spoil again after refurbishment?

We dey give warranty for our services. If, as our technicians dey work, dem see say even after repair di drive no go last like new drive, we go consult you to know whether make we continue di refurbishment. Di aim of our work na to restore di drive to di technical condition of a brand-new drive.

10) Error F519 show for di controller, wetin e mean?

Dis message mean say di drive dey require much more current from di controller than e normally need (e dey work with difficulty). E fit be say di controller don spoil – for dat case, we go repair both di controller and di drive. We recommend say you send both of dem so we fit diagnose di problem and test how dem dey work after we repair di drive.
