Corrective maintenance refers to the actions taken to repair equipment or systems after a failure has occurred. This type of maintenance aims to restore functionality and ensure that everything operates smoothly again. For example, if a machine breaks down in a factory, technicians will perform corrective maintenance to fix the issue and minimize downtime. This approach is often reactive, meaning it happens after problems arise rather than preventing them. While it can be more costly in the long run, corrective maintenance is essential for addressing unexpected breakdowns and keeping operations running efficiently. Regular inspections can help reduce the need for frequent corrective maintenance.
