ALLISTER Product Lines We Repair
Our engineers are trained on the full ALLISTER product range. Below are the major product families we service.
Allister 2000 Series Garage Door Openers
Heavy-duty chain-drive and belt-drive operators for commercial and industrial applications. Common faults include motor burnout, worn sprockets, slipped belts, and limit switch failures affecting door travel precision.
Allister Access Control Modules
Logic boards and relay modules controlling gate access, door timing, and safety interlocks. Frequent repair needs include relay chatter, loose terminal connections, burnt capacitors, and loss of stored programming.
Allister Safety Sensor Systems
Infrared and mechanical sensors preventing door closure on obstacles. Typical issues involve misaligned photo-eyes, corroded lens covers, damaged receiver modules, and intermittent signal loss.
Allister Gate Operator Control Systems
Complete swing and sliding gate automation platforms. Repair focus includes motor speed controllers, encoder feedback failures, wireless remote receiver faults, and battery backup charging circuits.
Allister Transmission & Drive Components
Worm gears, sprockets, belts, and chains powering door and gate movement. Common wear includes gear tooth stripping, belt fraying, chain stretch, and bearing seizing affecting smooth operation.

Common ALLISTER Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ALLISTER equipment arriving at our workshop.
- ✓Motor hums but door fails to open — Allister 2000 Series motors commonly experience capacitor failure or stalled mechanical load. Worn sprockets or belt slippage prevent power transmission from motor to door carriage.
- ✓Door reverses immediately after closing — Allister limit switch wear, misalignment, or safety sensor activation. Dirty or bent limit switch contacts fail to signal proper door position, triggering automatic reverse logic.
- ✓Access control module loses programmed settings — Allister ACM logic boards suffer battery backup failure on the EEPROM chip, or power supply voltage regulation failure. Loose battery connections or corroded battery terminals cause memory loss.
- ✓Safety photoeye lights but sensor not detecting obstacles — Allister ELS photo-eye lenses collect dust and water buildup, reducing infrared beam strength. Misalignment due to vibration or impact prevents receiver from detecting transmitted signal.
- ✓Gate operator remote control non-responsive — Allister wireless remote receiver modules experience RF interference, dead batteries, or loose antenna connections. Receiver crystals drift out of frequency, preventing command recognition.
- ✓Intermittent door movement or stalling mid-cycle — Allister chain or belt wear allows intermittent slippage, or motor capacitor degradation reduces starting torque. Corroded connectors in safety circuits cause intermittent signal loss triggering reverse.

Frequently Asked Questions — ALLISTER Repairs
Do you repair Allister equipment anywhere in India?+
Yes. Synchronics repairs the full Allister product range — garage door openers, gate operators, safety sensors, and access control modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and all other cities. Same expert facility in Vadodara, Gujarat with 180+ trained engineers.
What is the typical turnaround time for Allister repair?+
Standard Allister repairs average 5-7 working days. Emergency rushes and in-house unit swaps available within 48-72 hours. We provide weekly updates and prioritize commercial/industrial clients to minimize property downtime.
Can you repair Allister 2000 Series motors that have burned out?+
Yes. Synchronics replaces burnt Allister 2000 Series motors with OEM-equivalent units or quality aftermarket alternatives. We bench-test all replacements under load, verify capacitor specs, and confirm shaft rotation before shipping. Motor burnout often signals worn drive belts or sprockets — we inspect and replace those too.
Do you stock Allister replacement parts?+
We maintain stock of high-demand Allister components including capacitors, limit switches, safety sensors, belts, sprockets, and relay boards. For rare or discontinued parts, we source globally within 10-14 days. All parts come with warranty and authenticity guarantee.
How do I know if my Allister safety sensor is faulty?+
Allister photoeyes should illuminate steady green on both transmitter and receiver. Intermittent or absent light indicates lens blockage, misalignment, or receiver module failure. Bring units to Synchronics for optical testing — we measure beam strength and confirm frequency matching, then recalibrate or replace as needed.
How do I send my ALLISTER unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a ALLISTER drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on ALLISTER repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your ALLISTER unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
