Unscheduled maintenance is something in which asset maintenance was planned but a slot for maintenance was not given. In simple words, time day, and date are not fixed for maintenance.

Several types of unplanned maintenance exist that we have discussed below:

Several Types of Unplanned Maintenance

1. Reactive Maintenance

It is done when an unexpected asset breakdown occurs and repair is done.

Reactive maintenance is done as a reaction therefore it can increase downtime and repairing can be a time-consuming process.

The maintenance team will have to first figure out what is the issue and what actions can be taken to resolve the issue.

2. Corrective Maintenance

Corrective maintenance gets the asset working again after it quits working appropriately.

Support for corrective goes from fixing a minor deformity that is making a resource run gradually, to fixes on a machine that has separated.

This sort of upkeep adjusts unanticipated issues that have not been anticipated or planned.

Unplanned maintenance & unscheduled maintenance can be used only when assets' productive life is over or giving maintenance is not possible.

If an organization is asset-intensive then this organization cannot rely on these maintenance techniques.
