Microwave oven repair made easy

As the title of the book implies, this book is written from the technician workbench point of view. No theories and long stories, therefore what is in this book is what you will expect first hand when a microwave oven is brought to your workshop for repair.

The author, Humphrey Kimathi has over 20 years’ experience in repair and service of home electrical appliances.

Microwave oven which was invented in 1958 by accident has become an household name as many families have adopted this mode of warming food in seconds.

An increase for the use of this technology has come with the need for personnel to service and maintain these gadgets.

Unlike other home electrical appliances, microwave repair is the most dangerous, both to the user and service personnel.

In this regard I have dedicated a full chapter on the safety around working on the microwave and also testing microwave leakage for the safety of the user before handing back the machine to the customer and also for the service technician-SAFETY FIRST!

The book is going for an introductory price of $ 10 USA dollars, Order Now!

  2. I wonder if the conclusion that the "Microwave oven was invented in 1958 by accident" is true? Because as I have read it was already invented in WWII when Radar was developed and an engineer noticed that the chocolat bar in his pocket melted when the RF radiation was beaming.

    1. You are very right Albert, but I like what you have just said" an engineer noticed that the chocolate bar in his pocket melted when the RF radiation was beaming" this exactly what I call invented by accident, so we are talking about the same thing, remember in the world war 11 this was used in Radar but after this incident they begin thinking how to use this for cooking(what made the chocolate to melt? kept this engineer thinking. all the best my friend, keep discovering!

    1. All magnetron operate at the same frequency 2450Mhz irrespective of the manufacturer, so it is the same.. So long as you new one fit, you are good to go.
