(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 Flower Mound, from Lakeside and the Long Prairie Road corridor to Wellington, Bridlewood and the Cross Timbers estates.
Business Profile

Flower Mound kitchens show three main microwave types. Over-the-range models dominate in homes built from the 1990s through the 2000s, including Wellington and Wichita Chase, and they pull double duty as the range vent, so a grease-clogged filter or failed vent fan is as common a complaint as a unit that will not heat. Newer lakefront homes at Lakeside often use them too, sometimes in compact kitchens where the microwave sits low over a slide-in range.
Larger homes in Bridlewood and the Cross Timbers estates more often have a built-in wall microwave, a speed oven or a drawer microwave set below the counter, and those come out of the cabinet differently from a mounted unit. A microwave stores high voltage in its capacitor even when unplugged, so do not open the case. If it hums without heating, sparks inside, or the turntable and light work but food stays cold, call for service.
Our Plano-based technicians cover Flower Mound from Lakeside and Parker Square along Long Prairie Road (FM 2499) and Cross Timbers Road (FM 1171) to Timbercreek, Wellington, Bridlewood, Montalcino Estates and Canyon Falls.

Yes. We repair drawer microwaves and built-in wall units from brands such as Sharp, Wolf, Thermador and Monogram. Drawer models have their own glide and door mechanisms, and their controls are often damaged by spills from the counter above. We diagnose the fault and give a written estimate before any part is ordered.
A loud or rattling vent fan is usually a worn fan motor or a loose blower wheel, and both can typically be repaired. Start by washing or swapping the metal mesh filters, because grease-loaded mesh forces the motor to strain. If the microwave is old and also has heating problems, replacing the whole unit may be the better choice.
Yes. We serve Wichita Chase, where homes date to the early 2000s, and Wichita Creek Estates, with acre lots from the early 1990s, in Flower Mound ZIP code 75022. Microwaves in both neighborhoods are often the second or third unit in the kitchen, and we check the mounting bracket as well as the appliance.
