At Upfix, we repair your original microwave control board at the component level and return it plug-and-play—so you keep the exact behavior your appliance had when it was healthy. No hunting for a pricey new board that might be backordered. No gambling on a used part. Just a board that powers up, listens to the door switches and sensors, and runs the magnetron when it should. We back appliance control board repairs with a 24-month warranty, because a real fix should last in real kitchens.
