LG Microwave lmv1683st not heating. How to repair?
One of the common problems of all types is microwave - not heating. Typically problem could be in diode. The diode converts the A/C power output of the transformer to D/C, doubling the voltage to nearly 5,000 volts. This high voltage powers the magnetron to heat the food. If the diode burns out, the magnetron won’t receive enough voltage to operate, preventing the microwave from heating. When the diode fails, it is often visibly burned out. Inspect the diode and if the diode is burned out, replace it. Today we have prepared a guide, which helps you to replace diode in microwave LG lm1683st.
