DAVIS Product Lines We Repair
Our engineers are trained on the full DAVIS product range. Below are the major product families we service.
Davis Heavy Duty Contact Systems
Electromechanical switching relays and contactors with high inrush current capacity. Common failures include burned silver contacts, sticking armatures from coil burn-out, and loss of contact pressure after decades of switching cycles in industrial environments.
Davis Solenoid Operated Valves and Switches
24VDC and 120VAC solenoid-actuated switching systems for pneumatic and hydraulic line control. Typical issues: coil winding failure, plunger sticking due to corrosion, voltage drop across solenoid leads, and failure of internal check valves.
Davis Push Button and Limit Switch Stations
Ruggedised mechanical limit switches and control stations for process line monitoring and emergency stop circuits. Prone to contact oxidation in humid factory environments, mechanical binding from dust ingress, and spring fatigue in frequent-cycle applications.
Davis Indicator and Alarm Systems
Colour-coded pilot lights, audible alarm modules, and condition indicator panels integrated into control cabinets. Failure modes include bulb burn-out, socket corrosion, buzzer solenoid failure, and loss of 24V logic supply to indicator circuits.
Davis Control Transformer Assemblies
Step-down transformers (480V to 120V, 440V to 110V) used to power logic and control circuits in legacy Indian industrial panels. Common failures: primary winding open circuit from voltage surges, secondary winding short from moisture ingress, core saturation, and burnt terminal blocks.
Davis Timing Relay and Counter Systems
Electromechanical timers and mechanical counters for process sequencing and production monitoring on textile mills, packaging lines, and automotive assembly. Failures include worn escapement mechanisms, timer motor burn-out, loss of timing accuracy, and counter ratchet failure.

Common DAVIS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DAVIS equipment arriving at our workshop.
- ✓Davis Contactor Burned Silver Contacts and Arcing — After 20+ years of switching high inrush currents (especially motor starts), Davis heavy-duty contactors lose contact pressure and develop micro-gaps. Moisture and industrial contaminants oxidise the silver, causing arc-over and electrical noise.
- ✓Davis Solenoid Coil Open Circuit and No Pull-In — Insulation breakdown in the solenoid winding due to thermal cycling, moisture ingress, or voltage spikes. Common in 24VDC systems where loose panel grounds create voltage transients across the solenoid leads.
- ✓Davis Limit Switch Plunger Sticking and Mechanical Binding — Corrosion and rust inside the switch enclosure from moisture and process humidity (common in food processing and textile mills). Dust and oil accumulation jam the spring-loaded roller or lever arm, preventing full travel and contact opening.
- ✓Davis Control Transformer Primary Winding Open or Shorted — Lightning strikes or transient voltage surges from motor soft-starters and VFDs cause primary winding insulation failure. Short circuits between windings create smoking and complete loss of 120V/110V secondary supply to all logic circuits.
- ✓Davis Pilot Light Socket Corrosion and Loss of Indication — High humidity in Indian manufacturing environments corrodes brass socket contacts and bulb pins. Salt spray in coastal plants accelerates oxidation of bakelite sockets, creating intermittent contact and bulb flickering.
- ✓Davis Electromechanical Timer Motor Burn-Out and Loss of Timing — Synchronous timing motors in Davis timer relays fail from thermal overload (dust-clogged cooling), bearing wear after 15+ years, or single-phasing from loose power connections. Loss of 50Hz line frequency or voltage sag causes timer to lose synchronism and skip cycles.

Frequently Asked Questions — DAVIS Repairs
Do you repair Davis equipment anywhere in India?+
Yes. Synchronics repairs the full Davis product range — contactors, solenoid switches, limit switches, control transformers, indicator systems, and timing relays. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Vadodara, and all other industrial cities. Centralised repair facility in Vadodara, Gujarat.
Can Synchronics rewind Davis solenoid coils and control transformer primaries?+
Yes, absolutely. Synchronics has in-house winding equipment and maintains original wire gauges, insulation types, and turn counts for Davis solenoids (24VDC, 120VAC) and control transformers (480V-to-120V, 440V-to-110V). We test continuity and insulation resistance after rewinding to ensure safe operation in your control cabinet.
What is the typical turnaround time for Davis relay and contactor repair?+
For most Davis switching repairs (contact replacement, spring re-tensioning, solenoid testing), turnaround is 5-7 working days. Coil rewinds and transformer rebuilds may take 10-14 days. For emergency downtime, expedited same-site repair visits are available in Vadodara, Ahmedabad, and Surat regions.
How do I know if my Davis solenoid is burned or just needs cleaning?+
A burned Davis solenoid coil will show zero resistance (open circuit) when tested with a multimeter across the two leads. If resistance reads normal (8 to 50 ohms depending on voltage rating), the coil is intact — likely the plunger is stuck or armature return spring is weak. Synchronics performs free diagnostic checks and advises whether rewinding or mechanical service is needed.
Do you stock spare Davis parts or rebuild old contactors and relays?+
Synchronics does not stock Davis OEM parts (most are now obsolete from the manufacturer). However, we rebuild Davis contactors, relays, and solenoids to like-new condition using matched replacement coils, contact assemblies, and springs. We also identify compatible modern alternatives (Allen-Bradley, Schneider, Siemens equivalents) where upgrading your control cabinet makes economic sense.
How do I send my DAVIS 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 DAVIS 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 DAVIS 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 DAVIS 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.
