The average microwave lasts 7-10 years with proper maintenance, but the repair-vs-replace math shifts dramatically depending on age. A repair that makes perfect sense on a 5-year-old unit becomes a poor investment on a 12-year-old one. These 5 guides break down the decision for microwaves at 10, 12, 15, 5, and 7 years old.
Each guide applies the 50% rule adjusted for remaining useful life: the older the microwave, the lower the repair cost threshold should be before replacement becomes the smarter financial decision. We also factor in energy efficiency gains from newer models, California utility rebates, and the hidden costs of replacement (delivery, installation, disposal).
