What's the most common Avanti microwave problem you see?

On Avanti microwaves it's usually magnetron failures and door switch/interlock faults. Avanti specializes in compact and specialty appliances — mini fridges, portable washers, small-footprint wine coolers — designed for apartments, dorms, and secondary spaces rather than full-size kitchens. We diagnose on-site before quoting so you know the exact cause, not just a guess.

Do you use genuine Avanti parts for microwave repair?

Yes — we stock genuine Avanti OEM parts for common microwave repairs. Avanti specializes in compact and specialty appliances — mini fridges, portable washers, small-footprint wine coolers — designed for apartments, dorms, and secondary spaces rather than full-size kitchens. Typical microwave repairs run $100–$300, credited against the diagnostic fee.
