ebm-papst EC fan repair for HVAC and chiller service companies
Star Automations repairs ebm-papst style EC fans and EC motors used in AHUs, condensers, chillers and cooling systems, in batches for HVAC service and O&M companies. We work from Bengaluru, assess every unit, repair what can be repaired and tell you clearly what cannot.
Built for O&M, AMC and HVAC service companies
Most EC fan failures are electronics board faults. We repair the board at component level, so you do not replace the whole fan.
If you maintain chillers, AHUs and condensers for several sites, failed EC fans pile up. Replacing each one is slow and expensive. We repair them in batches, so you cut downtime and cost across your contracts. Welcome to HVAC service providers, facility management companies and chiller AMC contractors.

How the batch programme works
- Send photos of the fan labels, quantity and faults.
- Ship a sample batch by courier or arrange a bulk pickup.
- We tag each unit and classify it: board fault, winding fault, bearing fault or beyond economic repair.
- We repair, test and return the units with a unit-wise report.
- If a unit cannot be repaired economically, we quote a refurbished, tested EC fan where available.
Where the fans are used: air handling units, fan coil units, condensers, chillers, cooling towers, precision air conditioners and cleanroom filter units.
Refurbished EC fans and exchange units
To keep a chiller or AHU running while your fan is in repair, we can supply refurbished, tested EC fans and spare control boards, subject to availability. Send the model and we confirm stock and price. In stock now: ebm-papst 4114 NHH, 24 V DC axial fan (new).
Fan motor bearing replacement
Bearing noise, vibration and heat are early signs of a failing fan motor. We replace the bearings in EC fans, condenser fan motors and blower motors, check the rotor, balance the rotor or impeller where needed, and test the fan before return. Bearing work is done together with board-level repair, so one visit fixes both.
Frequently asked questions
Do you repair ebm-papst EC fans and EC motors?
Yes. We repair the electronics of ebm-papst style EC fans and EC blowers, and the motor assembly including bearings and rotor faults, for HVAC, chiller and cooling applications. Send the model label and the fault for a first assessment.
Can you handle 100 or more faulty EC fans from one HVAC service company?
Yes. For O&M and HVAC service companies we run batch programmes: each unit is tagged, assessed and classified as board fault, winding fault, bearing fault or beyond economic repair, then repaired and returned with a unit-wise report. We usually start with a sample batch.
Which fan faults do you repair?
Fan does not start, runs at the wrong speed, trips or overheats, bearing noise, communication or control-signal faults, and burnt or water-damaged electronics.
Do you serve Bengaluru customers?
Yes. We work from our Bengaluru facility, with Chennai and Puducherry also available, and units can be sent by courier or picked up in bulk.
Is repair or replacement better for an EC fan?
We give a per-unit finding. When a repair is not economical we say so and quote a refurbished, tested EC fan where available, so your chiller or AHU is not down for long.
Which equipment uses these fans?
Air handling units, fan coil units, condensers, chillers, cooling towers, precision air conditioners, cleanroom filter units and refrigeration systems.
Are you an authorised ebm-papst service centre?
No. Star Automations is an independent repair company. Brand names are used only to identify the fans we repair.
How do I send units?
Send photos of the fan label, the quantity and the fault on WhatsApp +91 97866 22233 or email info@starautomations.com. We reply with the next steps.

How fast can a batch be turned around?
Emergency same-day, urgent 3 working days and standard 7 working days are available where the fault and parts allow. For a batch, the timeline is stated on the quote.
Do you replace bearings in fan motors and EC fans?
Yes. We replace worn bearings in EC fans, condenser fan motors and blower motors, then check the rotor and, where needed, balance the rotor or impeller, and test the fan before return. Bearing noise caught early avoids a burnt motor or board.
