Electronics repair for construction machines
We repair the electronic control units used in excavators and loaders — one of our specialities, run for years alongside the pump side of the business.
A control unit is usually one of the most expensive single parts of a construction machine, and on older models it can also be hard to source. Repairing a damaged module is then noticeably cheaper than buying a new one, and often faster too — there is no wait for a part to be imported.
Typical symptoms worth checking before you order a new module: the machine will not start although the starter is sound, hydraulic functions work only intermittently, random faults appear on the display, the controller loses its settings, or the machine cuts out for no reason. Common causes are voltage surges, water ingress and corroded contacts, or chafed wiring looms.
Before you order a new part, get in touch — we will check whether the damaged module can be brought back into service.

What is worth having ready
The more of this you can give us straight away, the sooner you get a specific answer instead of a general one.
- 01Make, model and year of the machine
- 02The controller part number, if it is legible

- 04Fault codes from the display, if the machine shows them
Questions and answers
- Is repairing a controller worthwhile instead of replacing it?
- In most cases yes — the controller is one of the more expensive parts of the machine and on older models it can be hard to source. Repair is usually cheaper and faster than importing a new module. Only an inspection of the particular unit gives a definitive answer.
- How can I tell the problem lies in the electronics?
- Typical symptoms are hydraulic functions working only intermittently, random faults on the display, the controller losing its settings, or the machine cutting out for no clear reason. Common sources are voltage surges, water ingress with corroded contacts, and chafed wiring looms.
