Today’s homes are equipped with many appliances to ease our daily lives. This free online course takes you through the operating principles, advantages and disadvantages, maintenance and repair of these devices. Many appliances are used in the kitchen but we begin with the most common and maybe most essential type: lights. The course lays out the characteristics and working principles of lamps. We identify the four main types of lamps: incandescent, fluorescent, compact fluorescent and light-emitting diodes (LEDs). Clean water for cooking, cleaning or drinking is also essential in the home and we guide you through the operation and maintenance of water purifiers, including the activated carbon, reverse osmosis and ultraviolet varieties.

While food was once cooked over a fire stove or even an open fire, it can now be cooked much faster using various appliances. This course shows you how a heating element is made and works. We then demonstrate how to safely service and maintain appliances like the rice cooker as we investigate both complex cooking devices and their simple counterparts, like the electric kettle. Cooking appliances are not the only type of heating machine found in the home: heaters, clothes dryers and washing machines also feature heating elements as part of their design and we show you how to operate and repair them.

We then discuss air appliances in terms of how they work and how to maintain them. The course then delves into the various types of electric grinders and mixers used in kitchens. But what about powering all these appliances? In the course’s last section, we examine various types of uninterrupted power supply (UPS) unit and explain how they regulate voltage. We then discuss their operation and troubleshooting process. This course suits anyone who wants to learn the correct operation, working principles, maintenance and repair of home appliances. Aspiring electricians and repair professionals can also benefit as we show you how to keep homes running smoothly.
