Corrective Maintenance

What is corrective maintenance?

Corrective maintenance occurs when a maintenance technician discovers a problem while completing a preventive maintenance, inspection, general, or emergency work order. Corrective maintenance identifies, isolates, and rectifies a fault so that the equipment, machine, or system can be restored to its original condition.

Corrective maintenance workflow

Overview

Corrective maintenance is initiated when an additional problem is discovered during a separate work order. For example, during an emergency repair, as part of a routine inspection, or in the process of conducting preventive maintenance, a technician spots another issue that needs corrected before other problems occur.

Upon discovering an additional problem, corrective maintenance is planned and scheduled for a future time. During the execution of corrective maintenance work, the asset is repaired, restored, or replaced

How corrective maintenance decreases downtime

Think of corrective maintenance as something that gets caught just in time. For example, if you see that the brake pads in your car are just about worn down but haven’t affected the rotors yet, you caught them in time.

Within the maintenance arena, corrective maintenance is triggered when a technician sees something that is about to break or will affect the overall performance of a piece of equipment. It can still be repaired or restored without incurring downtime.

If corrective maintenance is not scheduled, the problem may become an emergency maintenance work order down the road and result in halted production lines, interruption in service, or unhappy customers.

Examples of corrective maintenance

Corrective maintenance can include a wide variety of equipment, systems, and situations.

For example, if you are performing preventive maintenance on a line of production equipment and notice significant wear on a critical part or component, you may initiate a corrective maintenance order to repair or restore that part within the next month.

If you are responding to an emergency request to repair a heating system in the middle of winter, you may notice that the HVAC system needs filters cleaned or replaced to improve efficiency and prevent further heat loss. You can restore the heat during the emergency call but you may schedule the corrective maintenance order to handle the filter issue later.

In a public works situation, you may be performing routine roadway repairs when you notice some signage damage from a recent storm. You can initiate a corrective maintenance order to restore that signage at a later date.

Benefits of corrective maintenance

Since corrective maintenance is performed “just in time,” the main benefit is reduced emergency maintenance orders as well as increased employee safety. Corrective maintenance work orders are scheduled and prioritized in a CMMS, that helps maintenance teams resolve problems before delays in production or service interruptions occur.

Corrective maintenance, coupled with good preventive maintenance, helps a business extend the lifetime of its assets, reduce employee injury, and optimize resource planning. Corrective maintenance work orders are often less expensive to implement than emergency maintenance work orders may need to be completed during overtime hours.

How to maximize corrective maintenance

Corrective maintenance has an important role within the scope of maintenance services in a business, residential complex, or factory setting. Technicians who can find and identify potential problems before they become emergencies can save the company a great deal of money.

In order to maximize the benefits of corrective maintenance, provide training and education to maintenance technicians and supervisors about what types of things to look for while they are providing preventive or emergency maintenance services.

Additionally, create a maintenance checklist of components that technicians can visually check quickly. You want your maintenance staff to catch as many problems as possible. This will generate more corrective maintenance orders and help keep your facility running smoothly.
