(469) 638-3215Microwave not heating, sparking, or the vent fan stopped working? ALAS Appliance Repair fixes over-the-range, built-in, drawer and combination microwaves across Argyle, from the US 377 and FM 407 corridors to Lakes of Argyle, Harvest and the acreage homes off Hickory Hill Road.
Business Profile

Microwave repair in Argyle depends a lot on the kind of home. In newer neighborhoods such as Argyle Town Village, built around 2018, and Waterbrook, over-the-range microwaves usually double as the range vent, so a noisy fan, dim lights or a greasy filter are as common as heating problems. Clean or replace the grease and charcoal filters first. If the plate rotates and the bulb lights yet nothing heats, the likely culprit is the magnetron, the diode or the capacitor.
Larger estate kitchens more often have microwave drawers in an island or a speed oven paired with a wall oven, and those bring their own failures: drawer motors, gear tracks, door sensors and control boards. Never force a drawer that will not open, since that can strip the gears. Those high-voltage parts can stay dangerously charged long after the plug is out, so leave the cabinet closed and let a technician handle it. Tell us the model and installation type when you book.
Our Plano-based technicians cover Argyle from the original town center and the US 377, FM 407 and I-35W corridors to Lakes of Argyle, Waterbrook, Country Lakes, Harvest, Canyon Falls and the acreage estates.

A loud vent usually points to a clogged grease filter, a loose fan blade or a worn fan motor. Homes in Argyle Town Village date from about 2018, so the unit may be original. Clean the filter and listen again. If the noise stays or the fan slows down, the motor likely needs replacing, which a technician can handle.
Yes. Speed ovens combine microwave and convection heating, and microwave drawers sit below the counter, both common in larger kitchens. Typical failures include drawer motors, door switches, convection fans and control boards. Have the brand and model ready, since many of these are built-in units paired with a wall oven and parts vary by model.
It might be, or it might be the circuit. Some older homes share kitchen circuits with other appliances, which can overload when everything runs at once. A microwave with a failing component can also trip a breaker. Try it on its own with nothing else running. If it still trips, stop using it and have it checked.
