NOTE

MAINTENANCE AND REPAIR OF VARIOUS ELECTRICAL APPLIANCES

Repairs refer to the process of fixing or restoring equipment or systems that have malfunctioned, failed, or suffered damage. Unlike maintenance, which focuses on preventing issues and ensuring ongoing functionality, repairs are reactive and aim to address existing problems.

Types of repairs

Types of repairs can include:

Emergency Repairs: Immediate fixes carried out in response to unexpected failures or breakdowns to restore functionality and prevent further damage or safety hazards.
Routine Repairs: Planned repairs conducted as part of scheduled maintenance activities to address identified issues or wear and tear before they escalate into major problems.
Major Repairs: Extensive repairs involving significant replacement or refurbishment of components or systems, often required after prolonged neglect or severe damage.

Differences between repairs and maintenance

Aspects	Repairs	Maintenance
Purpose	Reactive: Address existing issues or failures	Proactive: Prevent issues and ensure ongoing functionality
Timing	Typically conducted after equipment failure or malfunction	Scheduled and conducted regularly to prevent failures
Approach	Corrective: Aimed at fixing existing problems	Preventive: Aimed at avoiding problems before they occur
Focus	Restoration of functionality	Preservation of functionality
Cost	May incur higher costs due to unexpected nature	Generally involves lower costs due to planned nature
Frequency	Occasional and as needed	Regular and scheduled
