Teco equipment in this catalog is listed by model or part number. Send the model from the nameplate and the fault, and it will be matched to an engineer who works on that kind of unit.
Common faults
What usually fails on a unit like the JNTHBCBA0015BE-U-15HP
AC drives fail in a small number of predictable ways: the power stage, the DC link, cooling, or the control electronics. Most can be repaired at component level, which keeps the original drive, its parameters and its wiring in place.
Power stage failure
Shorted IGBTs or rectifier diodes, usually after a motor or cable fault, a supply surge or long-term overheating. The drive trips on overcurrent or short circuit at start, or blows input fuses.
DC bus capacitors
Electrolytic capacitors lose capacity with age and heat. Symptoms are DC bus ripple faults, undervoltage trips under load, or a drive that fails after a long shutdown.
Cooling fans and heatsinks
Worn fans and dust-packed heatsinks cause overtemperature trips, often only in summer or at full load.
Control and gate-drive boards
Faults in the control board, gate drivers or switched-mode supply show up as a dead keypad, communication loss, or random trips with no load-side cause.
Braking chopper and resistor
Overvoltage trips while stopping high-inertia loads point to a failed chopper transistor, an open braking resistor or a ramp set too short.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Note the exact fault code and what the machine was doing when it tripped.
- Check that fans turn and that filters and heatsink fins are clear.
- Measure the incoming supply on all three phases.
- With the motor cable disconnected from the drive, have the motor insulation tested.
Leave to a specialist
- Opening the drive or testing the power stage: the DC bus holds a lethal charge after switch-off.
- Replacing IGBT modules, capacitors or gate drivers.
- Reforming capacitors on a drive that has been in storage.
Getting it fixed
How to get the JNTHBCBA0015BE-U-15HP repaired
What to send with it
- The drive, or the failed power or control module if the drive is cabinet-built.
- The fault code or a photo of the fault history.
- A parameter backup or a photo of the keypad's key settings, if the drive still powers up.
- A note of the motor rating and the application (pump, fan, conveyor, winder).
Onsite or ship-in
Technicians work onsite from our Hyderabad base and travel to plants across India; anything that can be removed can also be sent to MachineryFix from anywhere in the country.
Warranty. Repairs carry a warranty of 30 days to 6 months, depending on the item and the repair; the exact term is confirmed before work starts.
FAQ
JNTHBCBA0015BE-U-15HP repair questions
Is it worth repairing the Teco JNTHBCBA0015BE-U-15HP rather than replacing it?+
Usually, yes, when the fault is in the power stage, capacitors, fans or a board. A repair keeps the same drive, frame size and parameters, so nothing in the panel or the control logic has to change.
Can the parameters be kept after repair?+
In most cases the control board and its memory are untouched by a power-stage repair. If the control board itself has failed, send a parameter backup or photos so the settings can be restored.
Does the Teco JNTHBCBA0015BE-U-15HP have to be sent in, or can an engineer come to the plant?+
Either. An engineer can diagnose it in place and repair it there or take it away, or the unit can be sent to MachineryFix from anywhere in India. The diagnosis and repair cost are confirmed before any work starts.
Is MachineryFix connected to Teco?+
No. Teco and the model name are used only to identify the equipment. MachineryFix is an independent repair service and is not affiliated with or endorsed by Teco.
