It is recommended that microwave ovens be installed on a separate line. If your oven is connected to a shared line and some other device is drawing power when you start the oven, it may cause the breaker to trip

MOD# C880-6402990 ser IMF0216838 Type 30S My issue is I had my microwave plugged into the extra outlet. I turned on the microwave and then it seems like it tripped something in the stove.


Check the circuit breaker for the house. It might be tripped. Sometimes a breaker will trip without moving the handle to indicate a trip. Reset the breaker several times.

H7871SOGB/03 combi. Why isn't it working?


The fact the breaker in the fusebox tripped indicates a fault in the appliance that is probably safety related. If it was the mcb (micro circuit breaker) it indicates a sudden overload. If it was the rcd (residual current device) it indicates there might have been a live circuit shorted to earth.

The fault is likely to be internal and it is potentially dangerous for unqualified people to fiddle about inside microwave ovens. Many brands are cheap throw-away items these days because a visit to the repair shop tends to cost more than a replacement.

The Neff brand is a premium brand and although repair costs are expensive it is likely to be (marginally) cheaper than a replacement.

Whirlpool GH5184XPS Microwave Oven F7 error, trips circuit breaker


Check the high voltage capacitor, it normally shorts, "discharge with screwdriver" unhook one side and set meter to ohms. Check high voltage diode tied into one side of the capacitor, "unhook from chassis ground" set meter to ohms and check for short, sometimes cracks, "must be replaced" If the diode is open meter does not have enough forward bias to check.

Lg microwave oven trips circuit breaker


The magnetron probably has a partial short pulling more current than normal as it runs, the other two items that give trouble is the high voltage diode, "sometimes cracks" to the high voltage capacitor, "usually shorts"

I don't know if it is the microwave that blowing the circuit, but that is what my brother said. It blows the circuit sometimes when they use it. Model# MS-104yc 1.5KW or maybe the combination of the air...


Are you referring to tripping the breaker? The microwave runs on 110 volts, and if you are referring to a central HVAC unit, it runs on 220. No way the one could blow the other, unless you are referring to a window unit. If it is tripping the breaker, you could start by replacing the breaker (can buy at Home Depot or Lowes), and if it still continues to trip the breaker, then it is more than likely the capacitor.
