The repair-vs-replace rule for microwaves
With new over-the-range units starting around $250, most repairs above ~$150 do not pay off. Repair only a newer microwave with a cheap, accessible fault — otherwise replace.

Frequently asked questions
- How long should a microwave last?
- A mid-range microwave typically lasts 8–10 yrs. Budget models run shorter and premium units longer — see the lifespan table above for the full tier breakdown drawn from NAHB and InterNACHI data.
- Is it worth repairing a microwave?
- It depends on age and the specific part. A typical major microwave repair runs about $120–$300 installed. If that is more than half the price of a comparable new unit and the appliance is past two-thirds of its expected life, replacement usually wins.
- What microwave repairs can I do myself?
- The parts marked DIY-friendly above — typically thermostats, elements, seals, and pumps — are within reach for a careful owner with basic tools. Anything tagged gas, refrigerant, or high-voltage should go to a licensed professional.
- Does my location change the repair cost?
- Yes. Labor is the largest share of most repair bills, and technician wages vary by metro. The same job can differ 25% or more between markets — check your local rate on the labor-cost pages, then run the calculator with your actual quote.
