Microwave Repair Near Me in Rockwall, Dallas, TX

A microwave that spins its turntable and lights up but leaves food cold has lost its high-voltage circuit. The technician discharges the capacitor safely, then tests the high-voltage diode, the capacitor, the transformer windings and the magnetron's filament. The diode and the door interlock switches tend to fail before the magnetron does.

Door switches deserve attention on their own. A microwave in a busy kitchen is opened and closed many times a day, and a worn interlock can blow the main fuse every time the door is shut.

Many Rockwall homes built during the growth of the last few decades put an over-the-range microwave above the cooktop. Those units also run a vent fan and a cooktop light, and steam and grease rising from below can coat the fan motor and the control's underside. A vent fan that hums or runs slowly is checked for motor resistance and bearing drag.

Touchpads that stop responding are tested at the ribbon connector to tell a failed membrane from a failed control board. A unit damaged by a power surge is checked at the board's input before the touchpad is blamed.
