What do LG microwave repairs usually involve?

With LG microwaves, it is usually failed magnetrons, faulty door switches, inverter board failures, and clogged grease filters and vent fans. About once a month, soak and wash the metal grease filters on the underside of an LG over-the-range microwave.

Does the kind of house I live in matter for my LG microwave?

In condo kitchens, over-the-range units vent grease into tight spaces, so clogged filters and fan failures are frequent.

LG microwave repair: what to know

A short orientation before LG microwave service: LG makes countertop microwaves and over-the-range models with vent fans built in, and many rely on Smart Inverter power control.

Failed magnetrons, faulty door switches, inverter board failures, and clogged grease filters and vent fans account for most of the LG microwave work we do. The calls we get tend to mention running without heating, door switch not catching, and vent fan dead. Food staying cold while the microwave runs means it is time to stop using it and schedule a repair, because opening it up around the high-voltage parts is unsafe. Sparks inside usually come from a damaged waveguide cover or metal in the cavity.

A Smart Inverter model swaps the traditional transformer for an inverter board, so when it stops heating the board may be at fault instead of the magnetron, and both have to be tested safely after the charge is discharged. Over-the-range units add lights, dampers and vent fans that can fail on their own, apart from the cooking circuit. Paying for an inverter board or magnetron on an aging countertop model rarely makes sense, but an over-the-range unit often justifies repair given what installation costs.

Surges when the power returns after a thunderstorm are a common reason a microwave control board fails without warning. A microwave visit starts with the door switches and fuses, then the high-voltage section, which is discharged before it is tested.

If the cause is the inverter board failures, the part and the labor go into a written estimate first, and the finished job carries 90 days on parts and 30 on labor.

Do not use an over-the-range microwave as a shelf for heavy items. Have the model and serial ready when you call about touch pad not responding; it lets us check parts first.
