Microwave Transformer Connection Diagram

By | July 30, 2022



If you’re a technician interested in understanding the basics of connecting a microwave transformer, you’ve come to the right place. In this article, we’ll take a look at a microwave transformer connection diagram and explain how it works.

A microwave oven transformer (MOT) is an essential component of any microwave oven. It helps transform the high-voltage alternating current (AC) supplied by the power grid down to a low-voltage direct current (DC) suitable for use in the oven. The MOT also includes a primary winding (input) and secondary winding (output). Connecting the MOT correctly ensures that the oven performs as expected and that it is safely connected to the power grid.

The first step to connecting a microwave transformer involves establishing a safe and secure grounding system. This means connecting the neutral connection to the nearest ground point to ensure safety. Once this is done, it is important to connect the primary winding (input) by connecting the hot line wires from the main line voltage circuit breaker to the two terminals of the primary winding. The secondary winding (output) should then be connected to the two terminals of the microwave oven terminal block. Finally, the ground wire should be connected to each other, the metal casing of the MOT, and the metal casing of the microwave oven.

By understanding the basic principles behind a microwave transformer connection diagram, technicians can make sure that their MOT is safely and correctly connected. This ensures that your microwave oven is properly supplied with power and works correctly.
