(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 Highland Park, from Highland Park Village and the Preston Road corridor to Beverly Drive, Lakeside Drive and Armstrong Parkway.
Business Profile

In most Highland Park kitchens the microwave is hidden. It may be a drawer unit set into an island, a speed oven in a wall-oven stack, or a countertop model built into a cabinet with a trim kit. Drawer microwaves have their own wear points, including the drawer motor, gear tracks and the sensors that tell the drawer when to stop, and a crumb or a bent track can keep the drawer from opening or closing fully. Built-in units can also overheat if the cabinet vents are blocked.
A lit interior and a spinning turntable with no heat usually point to a failed magnetron, high-voltage diode or capacitor. The capacitor can store a lethal charge long after the plug is pulled, which is why the outer cabinet stays closed unless a technician is doing the work. Speed ovens combine microwave and convection heating, so a fault can sit in either system, and the display message helps narrow it down. When you book, tell us the brand, whether it is a drawer, speed oven or trim-kit model, and what the display shows.
Our Plano-based technicians cover Highland Park from Highland Park Village and the Preston Road and Mockingbird Lane corridors to Beverly Drive, Lakeside Drive, Armstrong Parkway, Exall Lake and the neighborhoods west of Preston.

Usually, yes. A drawer that will not open or stops partway is often a drawer motor, a gear track, a door sensor or a control issue, and those parts can be replaced on many models. First make sure no utensil or crumb is lodged in the slide and the child lock is not engaged. If the drawer still stalls, the motor and sensors can be tested without removing the unit.
In many cases. Speed ovens are fitted to an exact cutout alongside a matching wall oven, so a replacement can mean a finish or size mismatch. Failures in the convection element, fan, door switches or magnetron are often repairable. We diagnose the fault first and confirm parts availability, then tell you whether repair is the sensible choice.
It can be. Built-in trim kits are designed to direct air around the microwave, and if the vents are blocked or the kit was not installed to match the model, heat builds up and can damage the controls. Stop using it if it smells hot. A technician can check the cooling fan, the vents and the installation.
