There are several types of maintenance used by organizations, some of them are proactive and some are reactive in nature. However, several organizations do not know which type of maintenance will be suitable for their business. In this blog, we will learn about corrective maintenance and the objectives of corrective maintenance. Will this maintenance be good for your business? So, without wasting any time let us begin!
What Is Corrective Maintenance?
Corrective maintenance is a type of reactive maintenance. In this strategy, the asset is brought back into the running state so that work can be continued. This type of maintenance is not used on high-priority assets, but corrective maintenance is only used on assets that are not important and are not highly dependable.
Corrective maintenance is used when a specific part of an asset or equipment does not work properly. Then the person responsible decides either to maintain it or replace it.
However, many organizations use Corrective maintenance along with condition monitoring maintenance to get better results as condition monitoring sensors can find and give indicators about asset performance.
But only if corrective maintenance is used then it rectifies the issue of assets and assets brought back into running condition.
What Is the Objective of Corrective Maintenance?
The objective of corrective maintenance is to bring assets into running condition as soon as possible when asset failure has occurred.
Another objective of corrective maintenance is to avoid production loss as it can delay production work and customers will be disappointed with late delivery.
According to the Research gate report, “The costs of maintenance are estimated to be between 15% and 40% of production costs (Dunn, 1987; Lofsten, 2000)”.

What Are the Advantages of Corrective Maintenance?
Advantages of corrective maintenance are:
1. Simple Process
Since this reactive strategy, the process is simple assets are given maintenance ad hoc. However, there is pressure on the maintenance team to bring back assets into the running stage as soon as possible so that production work can be started again.
2. Almost No Planning Required
In a corrective maintenance strategy, almost no planning is required because assets come to the maintenance team only when asset failure has occurred.
3. Low Cost for Short Term
This type of planning can be effective for assets such as light bulbs, long-lasting as maintenance is not required for a long time so maintenance cost is minimized.
What Are the Disadvantages of Corrective Maintenance?
The disadvantages of corrective maintenance are that it is reactive so Work delay can occur. Equipment maintenance costs can be increased as maintenance needs to be done as quickly as possible.
Corrective maintenance is done only on specific parts of an asset, not complete asset maintenance. It is also an objective of corrective maintenance. Downtime can be increased with corrective maintenance and asset life can be decreased as well.
Other than that, it makes assets unreliable as only the issue is resolved not the root cause is found in the corrective maintenance.
As a result, asset failure chances are increased, and employee safety concerns also rise because it can release some dangerous gases which can be harmful to all employees.

What Are the Characteristics of Corrective Maintenance?
Characteristics of corrective maintenance are discussed below:
1. Corrective maintenance can be planned and unplanned, however, mostly it is unplanned.
2. In corrective maintenance, the maintenance task is assigned and needs to be finished as soon as possible.
3. Moreover, asset failure has occurred & the issue needs to be rectified.
4. Most of the time corrective maintenance is applied only to those assets which do not have much dependability.
So, these are the main characteristics, advantages & disadvantages, and objectives of corrective maintenance. As we know, organizations are equipped with all types of assets and some of them are more important than others. So, we can say that corrective maintenance can be applied to those assets which are not as important for daily operations.
If corrective maintenance is applied to those assets which are important then the daily operation will be delayed, and productivity will because it is mostly reactive unless it is utilized with condition monitoring maintenance.
However, sometimes corrective maintenance is an effective solution, especially for those assets which organizations want to sell. Most importantly, corrective maintenance can be used with condition monitoring and when an issue is detected in advance.
In simple words, we can say that corrective maintenance can be used with condition monitoring maintenance or corrective maintenance can be used on those assets which are not crucial for daily operations.
