(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 Colleyville, from the Village at Colleyville and the SH 26 corridor to Montclair Parc, Ross Downs Estates and Whittier Heights.
Business Profile

Microwaves in Colleyville come in three broad types. Older homes, including the 1970s houses in Colleyville Estates and many 1990s kitchens, still use an over-the-range unit that doubles as the vent. Newer and remodeled estate kitchens favor microwave drawers set into an island and speed ovens that combine microwave and convection heat in the wall-oven stack. Each fails differently, so knowing which one you have saves time on the phone.
Over-the-range units wear out vent fans, light sockets and door switches, while drawers tend to lose their drive motors and gear tracks. Speed ovens can stop heating in microwave mode while the convection side still works, which usually points to the high-voltage section. Its capacitor may hold a dangerous charge even after the unit is unplugged, so the outer case should come off only in the hands of a technician. When booking, share the brand, the model number and the type of installation.
Our Plano-based technicians cover Colleyville from the Village at Colleyville and the Colleyville Boulevard, Glade Road and Hall-Johnson Road corridors to Montclair Parc, Ross Downs Estates, Highland Meadows, Whittier Heights and the Reserve at Colleyville.

A drawer that stalls is often blocked by a utensil or debris in the track, or its drive motor and gear assembly are wearing out. Check the track and clean any spills, then try again. Forcing the drawer can strip the gears. If it still stalls or makes a grinding noise, the motor, gears or a sensor likely needs replacing.
Yes. Speed ovens from brands like Wolf, Thermador and Miele usually slide out of the cabinet after a few screws are removed, which gives access for diagnosis. Share the brand, the model and which modes have quit, whether microwave, convection or both. If the speed oven sits above a wall oven, we protect the lower unit while working.
Usually not, unless the repair is small, such as a light socket, door switch or vent fan. Microwaves that old often need discontinued parts, and a new over-the-range model is easy to fit if the mounting plate and vent match. We look at the issue and the part cost first, then tell you which option makes more sense.
