(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 University Park, from Snider Plaza and the Hillcrest Avenue corridor to University Heights, Caruth Hills and Volk Estates.
Business Profile

Microwaves in University Park kitchens fall into two broad groups. Many older cottages and lightly remodeled homes still use an over-the-range microwave that also serves as the vent above the cooktop, so a failed fan or light affects cooking as well as reheating. Rebuilt homes more often have a microwave drawer set into the island or a built-in speed oven stacked with a wall oven, from brands such as Wolf, Thermador and Sharp. Both styles are common in the larger homes on the northern 75225 streets of University Park.
Drawer microwaves have their own failure points: the drawer motor, the gear track and the door switches that keep it from running while open. Speed ovens combine a microwave with a convection element, so a problem can be on either side. Never run a microwave empty, and never open the outer case yourself, since the high-voltage capacitor inside can hold a dangerous charge even when unplugged. Repair of internal parts belongs with a technician.
Our Plano-based technicians cover University Park from Snider Plaza and the Hillcrest Avenue, Lovers Lane and Preston Road corridors to University Heights, University Highlands, Caruth Hills, Idlewild and Volk Estates.
Common microwave problems

| Runs but won’t heat | Failed magnetron, high-voltage diode or capacitor, faulty door switch, failed transformer or thermal cutoff | Heat one cup of water for one minute. If it is still cold, stop using the microwave and schedule a diagnosis.Possible causes a technician checks: Failed magnetron, high-voltage diode or capacitor, faulty door switch, failed transformer or thermal cutoff Schedule a diagnosis |

Often, yes. Drawer microwaves use a small motor and a gear track to move the drawer, and a stuck utensil, a worn gear or a failed switch can stop it. Check that nothing is caught in the track and that the control lock is off. If it still will not move, we can diagnose the drawer mechanism and controls.
Yes. Speed ovens combine microwave and convection heating, so we check both systems. Tell us whether the problem happens in microwave mode, convection mode or both, and note any error codes. Many speed ovens are stacked over a wall oven in a single cabinet, so we plan for removal and support of the unit.
Many over-the-range microwaves turn the vent fan on automatically when they sense heat from the cooktop below. It should shut off as the area cools. If the fan runs with the cooktop off and everything cool, a thermal sensor or the control board may be faulty and a technician can test it.
