    Common Sense Troubleshooting of Microwave Ovens

    Effective troubleshooting begins with a systematic approach. The objective is to eliminate the cause, not just the symptom. Therefore, the way to a successful repair is guided by mindful alertness and common sense. Here are three basic guidelines:
    1. Be observant and alert to the obvious.  The majority of common problems that occur in microwave ovens are conspicuous and readily detectable by one or more of the senses -- your ears, eyes, or nose. For example, listen for abnormal, unusual sounds -- or the lack of a sound, such as the normal click of a microswitch. Look for the obvious:loose or burned connections, disconnected wires, broken binding or melted parts. And don't overlook the presence of any unusual odors. Many times the problem is staring you right in the face.
    2. Keep an open mind.  Keep in mind the areas where a particular trouble can potentially exist, but don't allow preconceived or indeterminate conclusions to blind you to the real problem. Ask yourself :'what could and could not cause this symptom?' Successful troubleshooting involves a process of logical deductions based on reasonable likelihood, then progressively eliminating all the least likely components until only the most probable suspects remain.
    3. Use your volt-ohm meter. For a final and positive diagnosis, use your volt-ohm meter to make systematic continuity and resistance tests. Experience has shown that, by means of authentic repair histories, most common problems can be quickly recognized and isolated by simply associating the symptom with the model or brand. Then, with careful observation and/or continuity tests, the problem can easily be diagnosed and solved.

Please make sure that you understand and are prepared to carefully follow the appropriate microwave oven repair safety precautions
