(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 Grapevine, from Historic Main Street and the SH 114 corridor to Countryside Estates, Winding Creek Estates and Lake Grapevine.
Business Profile

Microwave repair in Grapevine covers a wide mix of housing. Census survey data for 76051 shows that a little over a third of the area’s homes are in buildings with five or more units, so many microwaves here sit in apartment and condominium kitchens alongside the over-the-range units common in single-family homes. In both settings, the over-the-range microwave also works as the range vent, which means its fan, light and grease filters wear along with the cooking parts, even if the oven itself is rarely used.
A microwave that runs but does not heat, sparks inside, hums loudly or trips the breaker needs professional attention, because microwaves store high voltage in the capacitor even when unplugged. Never open the cabinet to look for a fault. Simpler issues, such as a turntable that stops, a stuck door switch or a dead light, are often quick repairs. When you book, mention the style of microwave, such as over-the-range, built-in or drawer, plus any building access details.
Our Plano-based technicians cover Grapevine from Historic Main Street and the SH 114, SH 121 and SH 26 corridors to Woods Addition, Dove Crossing, Countryside Estates, Winding Creek Estates, Western Oaks and the Lake Grapevine shoreline.

In most apartment communities, the built-in or over-the-range microwave belongs to the property, so the management office usually arranges the repair. If you own your condominium, you can book directly. Either way, tell us about gate codes, parking and any building rules so the technician can reach your unit without delay.
Clogged grease filters are the most common cause, so clean or replace them first. Next, check whether the microwave vents outside or recirculates through a charcoal filter, which also needs replacing over time. If the fan still sounds weak or noisy, the fan motor or damper may need repair.
No. Stop using it and unplug it. Sparking can come from metal in the cavity, damaged paint inside the cavity or a burned waveguide cover. A worn waveguide cover is a simple fix, but repeated arcing can damage the magnetron. A technician should inspect it before the microwave is used again.
