Introduction

Every appliance used by man especially electronic appliances require maintenance for steady functionality, durability, and even aesthetic.

Maintenance is the process of keeping equipment, tools, materials, or system in good working condition. Ogbuanya (2009) defined maintenance as the action taken to restore or keep an item in good functional order.

It involves decision making and planning by the personnel. Maintenance of electronic appliances can be in various forms such as dusting, lubricating, replacing burnt/damaged components, repairing, testing, using items for the purpose they are designed and following procedure for the operation of each appliance (Ogbuanya, 2009).

Different types of maintenance have been mapped out for the maintenance of appliances such as: preventive maintenance, predictive and corrective maintenance. Preventive maintenance is systematic detection and prevention of potential faults before they occur (Bayle, 2007).

According to Operations & Maintenance Best Practices ( No Date), preventive maintenance are actions performed on a time- or machine-run-based schedule that detect, preclude, or mitigate degradation of a component or system with the aim of sustaining or extending its useful life through controlling degradation to an acceptable level.
