How do brand and quality tier change the repair cost?
Brand and tier adjust the parts portion only — never labour. Basic and mid-range brands are the baseline; premium and luxury lines carry pricier OEM-restricted components. Pick a tier for a class-typical estimate, or a specific brand to override it.

Over-the-Range Microwave not heating: what usually causes it? Estimated
-
Magnetron replacement
Pro recommended$220–$400 CAD
Magnetron failure is the single most common reason an OTR microwave runs and spins the turntable but produces no heat; Canadian techs often replace the magnetron and high-voltage diode together in one visit.
-
Door interlock switch replacement
DIY possible$100–$220 CAD
A door (interlock) switch that fails to signal 'closed' is a frequent no-heat cause, since the safety circuit blocks the magnetron from firing until every door switch confirms closure.

Is it worth repairing a over-the-range microwave, or should you replace it?
A common rule of thumb: if the repair cost exceeds roughly half the price of a comparable new unit — or the appliance is past ~8 years for a over-the-range microwave — replacement is often the better value. The calculator's localized totals give you the number to weigh against a new-unit quote.
Prices are provincial-level estimates based on Job Bank labour-cost data, not fake city precision. Shopping in the U.S.? See the U.S. version of this page (USD). See the methodology for the localization method and named sources, or return to the Canadian appliance repair guide.
