The capacitor holds a dangerous charge after the appliance has been unplugged, and it does not care that the cord is in your hand. There is no version of this page that lists a way to check it yourself, and there is no figure published here for a magnetron — it is quoted after the diagnostic and never before. ### Why the figure starts low Because the commonest microwave repair by a distance is a door switch, an interlock or a control, and those sit at the bottom of a researched market range of about $100 to $300. Leading with the magnetron would make the page look authoritative and would be wrong most of the time somebody reads it. ### What people report, and what that is worth Owners do report magnetron failures on expensive oven-microwave combinations, sometimes within a few years, and in one documented case the repair came to about two-thirds of what the appliance cost. That is what people say rather than a measured failure rate, and this page is not going to dress it up as one. What it does mean is that on a combination unit the “is it worth it” conversation happens early, on the visit, before a part is ordered. ### The microwave-hood combination On these the microwave is also your ventilation, and its controls run the fan. So a dead microwave is a dead hood, and a vent that has stopped may turn out to be a microwave repair rather than a fan repair. It is one appliance doing two jobs, and it is priced from whichever half has actually stopped. ### What the figure is A starting point and a researched market range for South Florida rather than a quote for your appliance. The exact cost is confirmed after an on-site diagnostic and agreed in writing before anything is opened. What moves this figure Researched market range: microwave repair $100–$300 Door switches and controls are the commoner half by a distance The high-voltage side is never an owner repair, ever Whether it runs at all A microwave that will not start is usually a door switch or an interlock, which is the bottom of this band. A microwave that runs perfectly and produces no heat is the high-voltage side, which is the top. Those are two different appointments and you can tell us which from the kitchen. Where it is fitted A countertop machine sits on a bench. An over-the-range unit is bolted through a cabinet above a cooktop and takes two people down. A built-in with a trim kit comes out of a cabinet opening. That is the labor half of the figure and it is planned before the visit. Whether it is worth doing at all On a mid-range machine a high-voltage repair can approach a large share of what it cost new, and you get told that on the visit rather than after it. On a built-in or a combination unit set into an oven housing the arithmetic is completely different, because the alternative is cabinetry work rather than a delivery.

What the figure is A starting point and a researched market range for South Florida rather than a quote for your appliance. The exact cost is confirmed after an on-site diagnostic and agreed in writing before anything is opened. ### It runs but nothing heats up. That is the high-voltage side, and it is the top of this page. Stop using it, and do not open it. It is quoted after the diagnostic, and on some machines the honest answer is that the repair is close enough to the value of the appliance not to be worth doing. ### It will not start at all. Usually the cheaper half: a door switch or an interlock, sometimes a control. Three switches watch the door on most of these and any one of them can stop the machine, which is the design working rather than an unusual failure. ### Can I test the magnetron myself? No. The capacitor holds a dangerous charge after the appliance is unplugged. This is the one repair on this whole site where the answer is simply do not, and there is no qualified version of that sentence. ### Is it cheaper to replace it? On a countertop machine, often. On a built-in with a trim kit or a microwave set into an oven housing, usually not, because replacing it means an opening cut for a specific appliance. You get that comparison on the visit rather than an invoice afterwards. --- **[Read full article: Microwave repair cost](https://kitchenaidmiami.support/repair-cost/microwave-magnetron-and-high-voltage-repair/)**
