Inverters are electronic devices that convert DC (direct current) into AC (alternating current) and precisely control the speed and torque of electric motors. They’re a vital part of most modern industrial systems, improving energy efficiency, performance and process control.
At Sellweb’s Industrial Electronic Repair Centre, we specialise in the repair, servicing and refurbishment of industrial inverters — including single-phase and three-phase units, flux vector drives and motor inverters. Our technicians have decades of experience diagnosing and restoring inverter systems used in manufacturing, automation, HVAC, pumping and process control applications.
Whether your inverter powers a production line, a conveyor or a variable-speed motor, when it develops a fault you can rely on Sellweb to return it to full working condition quickly and cost-effectively.
If you have an inverter that is showing fault codes, producing inconsistent output or has failed completely don’t replace it before you’ve arranged for us to test and probably repair it.
Inverters operate in demanding environments where they handle high power loads and are subjected to heat, vibration and electrical stress — all of which can lead to faults developing over time.
Our repair centre deals with a wide range of inverter faults, including the most common inverter problems such as:
Power failure or no output
Fault codes or tripping issues
Blown input or output transistors (IGBTs)
Overheating or fan failure
Capacitor degradation
Control board or gate driver faults
Damaged power supplies or rectifiers
Contamination from dust, moisture or oil ingress
Many of these issues can be repaired or refurbished at a fraction of the cost of a replacement inverter, extending the lifespan of your equipment and reducing downtime.
Our engineers have multi-brand expertise, which means we can service and repair all the major brands of inverters used in UK industry, including:
Every inverter that comes into our UK facility undergoes a thorough diagnostic and repair process to ensure long-term reliability which consists of:
Initial Inspection & Cleaning – Each unit is carefully disassembled, inspected and cleaned to remove dust and contaminants.
Component Testing – Power devices, IGBTs, gate drivers and control circuits are tested for faults.
Capacitor Replacement – All electrolytic capacitors are replaced as standard to prevent future failures.
Fan Testing & Replacement – Cooling fans are checked and replaced if required to maintain proper thermal management.
Functional Testing – Once repaired, every inverter is fully tested under load to ensure it meets original performance specifications.
Quality Assurance – Final checks are carried out before the unit is returned, complete with a repair report and warranty.
