Over-the-Range Microwave: Repair or Replace? (2026 cost comparison)
The rule of thumb, from Consumer Reports: don't spend more than 50% of a comparable new unit on fixing the old one. For a microwave, that 50% line is about $100–$400 — a new unit runs $200–$800 and typically lasts 8–10 years. If a repair quote lands under that line and the microwave is not yet past its expected life, repair usually wins. Reviewed July 2026.

| Cost | Estimated range |
|---|---|
| Typical repair (this microwave, all faults we price) | $80–$450 |
| New microwave (unit only) | $200–$800 |
| Delivery + basic install general appliance figure | $100–$300 |
| The 50% line half a comparable new unit | $100–$400 |

How this is built: we apply the 50% rule (Consumer Reports) — spend no more than half a comparable new unit's cost on a repair — with its lifespan corollary (replacement is favored once the unit is past the midpoint of its expected life and the quote tops 50%). Columns are your repair quote as a share of a new microwave ($200–$800); the $100–$400 and $60–$240 thresholds are just 50% and 30% of that range. Rows use the midpoint of the expected life (about 5 years — halfway through a typical 9-year lifespan) and the top of the sourced 8–10 years range (10 years). Nothing here is a per-unit price or a recommendation — it is a transparent reading of the rule.
One more thing before you replace
A newer microwave can cut energy and water use, which shifts the math on an older unit even when a repair is cheap: ENERGY STAR notes clothes washers over ~10 years and refrigerators over ~15 years are common efficiency-driven replacements.
