San Francisco microwave repair for countertop, built-in, and over-the-range units
When a microwave runs without heating, sparks in the cavity, or an over-the-range hood loses light and exhaust, weeknight cooking slows down fast. Bay Appliance Repair diagnoses and repairs countertop, built-in, and over-the-range microwaves in San Francisco homes, condos, and managed properties, plus nearby Daly City and Peninsula communities.
We operate as At Bay Appliance Inc — service-area business from 140 San Pedro Rd, Daly City, CA 94014 (service calls only, no public walk-in shop). Call or text 415-585-5900 or email service@bayappliancerepair.com. Hours are Monday–Friday 8:00 AM–5:00 PM. Licensed under California BEAR #46247.
Common microwave problems we repair
- Runs but does not heat food or beverages (magnetron, diode, high-voltage capacitor, or fuse)
- Touchpad or membrane switch that will not respond while the display still lights
- Sparks, arcing, or burning smells from the cavity or waveguide cover
- Door that will not latch, close squarely, or start a cycle
- Turntable that will not rotate (drive motor, coupler, or roller ring)
- Over-the-range light or exhaust fan failures while the microwave still cooks
- Blank display, stuck keypad, or error codes after a power blip
Apartment and condo kitchens in the Mission, Sunset, Richmond, Noe Valley, and SOMA often share tight clearances, shared ventilation, and limited access above over-the-range units. Tell us whether the microwave is countertop, built-in, or over-the-range, and any recent power issues when you book so the technician brings the right panels and tools.
When to call a technician
- Sparks or burning smell: Stop using the microwave, unplug if safe, and schedule service—do not keep running a unit that arcs.
- Door will not latch: Door switches are safety-critical; forcing the latch can create a hazard.
- No heat with a running turntable: High-voltage components are not a DIY test—leave magnetron and diode diagnosis to a technician.
- Over-the-range mounting concerns: Loose mounts or damaged cabinets need careful assessment before parts are ordered.
Quick user checks—confirming the unit is plugged in, the door is fully closed, and the breaker has not tripped—are fine. Opening the high-voltage section or probing live components is not a DIY job.
How a typical repair visit works
We confirm the brand and model when you have it, test door switches, fuses, controls, and heating circuit on site, and explain repair versus replace options before ordering expensive magnetrons or sealed assemblies. We prefer OEM or quality equivalent parts when available. Qualifying work includes a 90-day parts-and-labor warranty. Same-day weekday appointments are often available depending on schedule and location—we work Monday–Friday 8:00 AM–5:00 PM and do not advertise overnight coverage.
