Microwaves deliver convenience, but they combine electronics, mechanical switches, and high-voltage components that can be costly to service. With a conservative ~10-year expected lifespan, a Samsung microwave may be worth repairing only when the issue is a clearly identified, low-cost component such as a door switch, keypad panel, or turntable motor and the total quote stays below the threshold.
If the microwave runs but doesn't heat, or trips breakers, the likely repairs involve magnetron/high-voltage circuits where replacement usually offers better value and less risk. Also weigh installation type: over-the-range units can have higher labor costs, but many owners still replace rather than repair after mid-life.
The replacement price benchmark reflects a mainstream countertop microwave listing at a major home-improvement retailer; models with convection/air-fry features can be significantly higher.
