Why is my GFCI oulet triping and the only thing on the circuit is microwave and stove exaust fan and light why is this?

power off disconnect motion light power on reset gfci. if it trips he problem is between breaker and rec.., or replace gfci with another one.is box dry even a small amount of water will cause it to trip. do not float grounds or neutrals, ensure that the black power wire is on the black terminal on line side.

If it trips the circuit breaker as soon as you turn the FAN on, suspect either a bad fan motor or a failed fan motor start capacitor. If you are able to turn the fan on but the circuit breaker trips as soon as the COMPRESSOR starts, it is possible that the compressor is seized.
If, on the other hand, the unit is tripping a GFCI (Ground Fault Circuit Interrupter) breaker or GFCI utility outlet, it is possible that neutral and hot are reversed at the outlet into which the trailer is plugged (happened to me this year at an RV park).

The refrigerator is supposed to be on a outlet by it self.
is there a gfci outlet in the circuit?
this can also cause trouble with a refrigerator

A GFCI detects shorts in an electrical system and isolates power to prevent that device from harming other components upstream. GFCI's do go bad so that possibility exists. However, I would recommend trying to plug in your refrigerator into another outlet in your kitchen that has a different GFCI plug. If it does not trip then the GFCI needs to be replaced. If you do not have another available GFCI outlet and you plug it into a regular outlet, your breaker for that service line MAY trip. Better off testing with another GFCI. If your second GFCI trips, then the problem is with your refrigerator...meaning you have a short in your refrigerator. If you think this is something you can troubleshoot...BE CAREFUL!!! Always unplug your refrigerator before going into the components of the refrigerator. One thing you can do is turn both the freezer and refrigerator temperatures OFF or to their lowest setting. Plug your refrigerator in and see if the GFCI trips. If it trips you have a major short...probably in the bottom of the refrigerator. If it does not trip, turn the freezer temperature on first and see if it will run without tripping the GFCI. If it runs, then turn the freezer temp OFF. Then repeat the process testing the refrigerator components. Ice makers have been known to generate shorts in the system as well. There are various ways to troubleshoot a fridge. If you do not have the required electrical troubleshooting skills then PLEASE call a service technician.

You should not have multiple GFCI devices in any one circuit. Change out the outlet and label it
GFCI Protected if necessary...Your problem of nuisance trips should go away.

from online Microwave Repair Manual: Totally dead oven (no lights, no clock, no display, no fan, no heat...)First, check power to the outlet using a lamp or radio you know works. The fuse or circuit breaker at your service panel may have blown/tripped due to an overload or fault in the microwave oven or some other appliance. You may just have too many appliances plugged into this circuit - microwave ovens are high current appliances and should be on a dedicated circuit if possible. If you attempt to run a heating appliance like a toaster or fryer at the same time, you *will* blow the fuse or trip the circuit breaker. A refrigerator should never be plugged into the same circuit for this reason as well - you really don't want it to be without power because of your popcorn!

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.

I assume you checked the power cord and house power circuit breaker panel... possibly tripped unrelated to your running the microwave empty.

If those are not the problems, then the main fuse is the most likely suspect for a totally dead microwave.

If you want to do more yourself, let me know and I will point you in the direction of some good resources.

Remove unit and check trip/reset switch on unit. Double check GFCI receptacle with plug tester with GFCI test button.

Hello

Coffee makers have a heating unit in them which draw a lot of current. If it is on the same circuit as refrigerator, toaster and other it will trip the breaker. Also, some breakers are more sensitive than others. Have an electrician run a separate circuit for the coffee maker outlet. Try running it in the dining room outlet, which I hope is separate from the kitchen outlets. Is the house old? Older homes have a lot of mixed up wiring.

Ground fault should not be used when you have a compressor plugged to it. The start amps can trip a ground fault. You can try to plug the unit on a regular outlet and if it doesnt trip the breaker then unit should be good. You can try to replace the ground fault if you need it (but make sure you have a higher amperage on the new one.)
