Cooktop & Microwave Repair

Q: "My induction cooktop says 'U' or 'F' — is it done?"

"Not usually. Induction cooktops look like black glass but are actually sophisticated electronics. 'U' codes usually mean cookware detection failed (a non-ferrous pan, a misaligned pan, or a dirty sensor). 'F' codes indicate a generator-board fault. Generator boards are replaceable modules — we stock the common Miele, Thermador, and Bosch ones."

Q: "Is it worth repairing a microwave?"

"Countertop microwaves: usually not — they cost $100–$300 new. Built-in microwaves, speed ovens, drawer microwaves, and OTR (over-the-range) units: almost always worth repairing. A Miele combi-microwave or a Sharp drawer microwave costs $1,800–$3,500 to replace, and most failures are $200–$500 to repair."

Q: "Do you service drawer microwaves (Sharp KB, Viking, Bosch)?"

"Yes. Drawer microwaves are increasingly popular in Tarzana kitchen islands because they keep the cooktop sightline clean. Sharp pioneered them and most Viking and Bosch drawer microwaves are Sharp-built underneath. The drive mechanism, limit switches, and control board are all serviceable."

Q: "Can you repair a built-in vent hood or microwave-vent combo?"

"Yes — though extraction-heavy vent-hood blower repairs sometimes need a two-tech crew because the units are heavy and awkward. We service Best, Broan, Vent-A-Hood, Zephyr, and the Miele and Wolf integrated hoods. Microwave-vent combos (OTR units) are routine."

Q: "Why does my induction cooktop sound like it's buzzing?"

"Induction generators drive power at ultrasonic frequencies, but the pan itself can resonate in audible ranges — especially with lightweight stainless or three-ply construction. Buzzing usually isn't a fault. That said, a rattle from under the glass, a fan that sounds like a hair dryer, or a pop-and-silence sequence is worth a diagnostic call."

Specialty: Induction electronics & drawer microwaves

Induction is electronics, not cooking

Half of the “broken induction cooktop” calls we take are not broken cooktops. They are non-ferrous pans that the cooktop has correctly refused to heat, dirty pan-detection sensors, or a glass surface that needs a cleaning with the manufacturer-specified cerium oxide cleaner rather than a Magic Eraser. When we arrive, we test with a known-good ferrous pan first, then escalate to electronics if there’s a real fault.

When there is a real fault, it’s almost always a generator board — the electronics module that drives a specific set of coils. Thermador Freedom cooktops have five separate generator boards (one per coil row); Miele KM 77 has two. We isolate to the failed module, replace that module, and avoid the trap some shops fall into of quoting a whole-cooktop replacement for a single-module failure.

Microwaves, speed ovens, and drawer units

Microwaves split into three service categories, and we do all three:

Countertop — honestly, we rarely recommend repair. A new mid-grade microwave is $150–$300. Unless it’s a Breville or similar premium countertop, we’ll tell you to replace.
Built-in microwaves & speed ovens — Miele combi-micros, Wolf M-series, Thermador Masterpiece. These are $2,000–$4,000 appliances worth serving for 10–15 years. Magnetron, high-voltage diode, door-switch, and turntable-drive failures are routine repairs.
Drawer microwaves — Sharp KB, Viking VMOD, Bosch. The drive mechanism that opens and closes the drawer is the #1 failure point. Individual parts are available and the repairs finish in a single visit.

Vent hoods: the forgotten appliance

No one thinks about a vent hood until it starts making a grinding noise at 11pm during a dinner party. We service vent-hood blowers, motors, speed controls, and touch-panel boards for the common Tarzana brands — Best, Broan, Vent-A-Hood, Zephyr, plus the integrated Wolf and Miele hoods. If the roof-mounted exhaust fan is the issue, we’ll climb up and diagnose; we just won’t touch the ducting itself.

When to call us.

Induction cooktop shows error code (E2, F9, U400) — a generator-board failure, coil sense issue, or cookware-detection fault. We decode Miele, Thermador, and Bosch induction codes on-site.

Gas burner won’t light — spark module, clogged burner port, or cracked ignition lead. Wolf and Thermador pro cooktops have distinct spark systems we stock for.

One induction zone works but adjacent zone doesn’t — individual generator modules often fail independently. We isolate to the failed module rather than replacing the whole cooktop.

Microwave turns on but doesn’t heat — magnetron, high-voltage diode, or capacitor. These are life-threatening voltages — this is not a DIY repair.

Drawer microwave won’t open — electronic drawer mechanism failure (Sharp, Viking, Bosch). Usually a limit switch or drive motor, not a board.

Vent hood fan runs rough or won’t turn off — motor, speed control, or touch-panel failure. Broan, Vent-A-Hood, Zephyr, Best.
