Every so often microwave trips circuit breaker - have plugged it into different outlets that are on different breakers with same result - opening the door while the microwave is running or after the timer has run out immediately trips the circuit breaker so was thinking one of the switches were the problem but can not locate the parts
Generally microwaves should be on their own breaker. Hard wired ones are required to be by code.
If yours has a plug - make sure the plug is original with the unit, not added later or spliced onto hard-wired power leads.
Plug into and outlet rated 15A as the only thing on a 15A branch circuit and try again. If it still trips, try a 20A line and circuit. If it trips that, trash the microwave and buy a new one. Nothing is meant to be repaired inside.

The door switches are designed to prevent the unit from running while the door is open. You probably have a blown fuse, and it's a white or dark grey ceramic fuse of 15A or 20A, available from local big box stores or appliance parts stores. The fuse is usually located on the floor of the chassis behind the control panel, or mounted in the same area as the door switches. Also, I'm really curious how the door switch got stuck while cleaning? That sounds scary...

It does sound odd for it to blow the breaker. It should blow the fuse, not the breaker. But looking at the exploded view diagram, I don't even see a fuse! Makes me wonder if this is some foreign model. *grin* In any event, you will need to replace all the door switches since they all have been stressed by the same overcurrent. Also be sure that all the switch mount and door latch parts are activating properly when you open and close the door. The switches (generic replacements) are widely available from local appliance parts stores.

Since power = voltage X current, 1.58kW / 120VAC = 13.166A
So this unit should be fine on a 15A breaker unless the breaker is bad, the wiring or a connection is loose somewhere between the breaker and the microwave, or the microwave's magnetron or high voltage transformer are failing and drawing extra current.
Microwaves should really be on the own separate breaker if at all possible. Plus, the more a breaker trips, the more work out it gets.
Have you measured the voltage at the outlet? If that's off, current and power will be affected. It should be about 110-125VAC.
A good power test for outlet and wiring integrity is a toaster, toaster oven, or hair dryer rated at about 1500 watts.
If it doesn't run and heat steadily, then there may be a problem with the house wiring or breaker.
If it passes this test, the problem is likely in the microwave.

Can someone tell me where i can find fuse for microwave convection/grill oven 5kv 700ma There is a other no on the fuse TUV5m41GF
SOURCE: microwave trips circuit breaker when plugged in
The circuit is probably a 20Amp circuit (see the number stamped on the circuit breaker switch). Most likely, it is the same circuit as the refrigerator, crock pot, window A/C unit, etc....
Also, if you are using an extension cord or a power strip or a surge protector. Those may not have a high enough power rating.
One other possibility (not likely) is that the circuit breaker is a 15Amp and the microwave is 1500 watts.
What else is cut off when the circuit breaker is tripped?
Solution is to use a different outlet for the microwave, or turn off any other applicance in the same circuit (except the refrigerator, of course).
Hope this helps!
Either you have defected (weak) circuit breaker and wiring or bad Microwave oven.
The 99.99 % house hold Microwave ovens pull less than 15 Amps. They may have internal ceramic 15A fuse or 15 Amp internal circuit breaker.
To isolate your problem:
1.
Plug your Microwave oven to different areas (different electrical circuit) if the different circuit breaker still trips... your Microwave oven has a short - Most of them has a small ceramic fuse 15 amps fuse.-also check some inter lock switches at door .
2.
If the Microwave oven works Ok then you may have:
2a. You may overload the existing electrical circuit, try to unplug some other appliances
2b. You may have bad electrical outlet receptacle (Replace it with the same type , - may need helps from licensed electrician)
2c. Weak or defect house hold circuit breaker. (Replace it with the same type , brand - may need helps from licensed electrician)
If you find the fuse blown or circuit breaker tripped, unplug everything from the circuit to which the microwave is connected (keep in mind that other outlets may be fed from the same circuit). Replace the fuse or reset the circuit breaker. If the same thing happens again, you have a problem with the outlet or other wiring on the same branch circuit. If plugging in the microwave causes the fuse to blow or circuit breaker to trip immediately, there is a short circuit in the power cord or elsewhere.
The microwave oven may be powered from a GFCI outlet or downstream of one and the GFCI may have tripped. (Removing a broken oven lamp has been known to happen.) The GFCI outlet may not be in an obvious location but first check the countertop outlets. The tripped GFCI could be in the garage or almost anywhere else! Pushing the RESET button may be all that's needed.
Next, try to set the clock. With some ovens the screen will be totally blank following a power outage - there may be nothing wrong with it. Furthermore, some ovens will not allow you perform any cooking related actions until the clock is set to a valid time.
Assuming these are not your problems, a fuse has probably blown although a dead controller is a possibility.
While you can do some repairs on your microwave, what you don't know can kill you... even on an unplugged microwave, so make sure you understand the dangers and how to reduce them before you try anything inside a microwave. If you want to do more yourself, go to the link at the top of this post.
