(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 Southlake, from Southlake Town Square and the SH 114 corridor to Timarron, Stone Lakes and Carillon.
Business Profile

For appliance repair in Southlake TX, microwaves are a smaller job but a varied one. Homes from the 1990s, in neighborhoods such as Timber Lake and South Ridge Lakes, often have an over-the-range microwave that doubles as the vent above the cooktop. Larger newer kitchens, including many in Carillon and Shady Oaks, use microwave drawers in the island, built-in models with trim kits, and speed ovens that pair microwave and convection heating inside the oven wall.
Each type fails a little differently. Over-the-range units often lose their vent fan or light, and door switches wear with heavy family use. Drawer models can stop opening smoothly when the drive mechanism or its sensors fail. Speed ovens add convection elements and fans that can fail apart from the microwave side. Because a microwave holds a high-voltage capacitor charge even when unplugged, the cabinet should only be opened by a trained technician.
Our Plano-based technicians cover Southlake from Southlake Town Square and the State Highway 114 and Southlake Boulevard corridors to Timarron, Stone Lakes, South Ridge Lakes, Carillon and the Bob Jones Park area.

Microwave drawers open with a motorized mechanism controlled by a sensor and the touch panel. Food debris in the track, a failed drive motor or a control fault can all stop it. Check for anything blocking the drawer and reset power at the breaker. If it still will not move, the drawer needs a diagnosis.
Yes. Speed ovens combine microwave and convection cooking in a built-in cabinet, and we work on them along with the wall ovens they are usually paired with. Note whether the microwave side, the convection side or both have stopped heating, plus any error code. Some repairs require pulling the unit from the cabinet, and we plan for that.
In many 1990s kitchens the microwave has already been replaced at least once, since microwaves rarely last as long as the house. A door switch, vent fan or light is usually a reasonable repair on a newer unit. If the magnetron or control board has failed on an older one, replacement may make more sense, and we will say so.
