What is the K.W. rating on the Serial plate? (KiloWatts) It it states,
A) 7 to 9.9 you need a 40 Amp breaker
B) 10 to 11.9 you need a 50 Amp breaker
C) 12 to 14.9 you need a 60 Amp breaker

You have number 6 wire so you're covered.

To connect:
It should have the newer style pigtail installed to the stove, and the newer receptacle to plug into.

The Top middle blade is for the Common wire. The White wire
The angled side blades use the Black, and Red wires.
Black goes to one angled blade, Red goes to the other.

The round pin on the bottom is for the bare copper wire.

Wire cable from receptacle the stove plugs into, up to the Service Panel. (Misnomered as Breaker Box)

A) The Common white wire goes to the Common Bus bar in the Service panel.

Looking at the Service Panel, you'll note there are three thick main cables coming in from the Service Meter can outside.

One cable comes down to the middle. Follow the copper thick flat strip from there, over to one of the bus bars on the side. This is the Common bus bar.

B) The other two thick cables coming in to the Service Panel are the 110 volt leads.
One cable goes to the Right side, the other cable goes to the Left side.

You'll be using a double-breaker. The breaker picks up power from both 110 volt leads.
This makes it 220 volts.

The Red wire goes to one side of the double-breaker
The Black wire goes to the other side of the double-breaker.

(The double-breaker has two screws in front. A double-breaker is two single breakers put together by the factory. One screw in front is for the Red wire. The other screw in front is for the Black wire)

C) There is a thick bare twisted wire coming into the Service Panel. This is the Ground cable.
Follow the copper strip from it to the bus bar it's attached to. This is the Ground bus bar.

The bare copper wire coming to the Service Panel from the receptacle, that the stove top is plugged into, goes to the Ground bus bar.

Example of a 50 Amp double-breaker, (Connecticut Electric brand),

I also would like you to download;
A) Installation Manual
B) Product Dimensions and Specifications Manual
C) Use and Care Manual

Advise you flip the Main breaker off before working on the unit's electrical wiring.
IF, you are in doubt at ANY time, whether the electricity is on, or not, GO AND CHECK.

110 volts can give you a very bad shock. It tends to knock you away.
220 volts can KILL you. It has a tendency to make you hold on. Your hands won't let go.

IF, you have ANY questions about installing, and are uncomfortable with this, PLEASE DO NOT ATTEMPT IT.
I want you SAFE above all else.

I will answer any questions you have regarding this. No matter if you deem them stupid or not.
To me there is no such thing as a stupid question.

Safety, safety, SAFETY.

One added thing. There are many different Service Panel manufacturers. You need THE circuit breaker style, that fits THAT Service Panel.

Main breaker in the off position, remove a breaker, and take it with you when you purchase the new double-breaker. Match how it looks. Have a clerk help you.

There is no power to the microwave model #mco160ub. Is there a fuse I can check?

Katherine, there is an internal fuse on microwaves. First, make sure you un-plug the microwave and then you will need to take the cover off of the unit. You will find screws on the back and sometimes the sides that hold the cover on. Once you have the cover off, look for where the power cord goes into the machine. There will be three wires coming out of the power cord, one black, one white, and one green. Follow the black wire and it will usually take you right to the fuse in a holder, or to a circuit where the fuse will be located. You will need to look at the end of the fuse to see what amperage fuse you will need. Most microwaves use either a 15 or a 20 amp fuse. Make sure you replace with the identical size fuse. If it blows again right away, that means you have further problems and should have it looked at by a regular repairman. Hope this helps!

Blowing breaker

In general house hold circuit breaker of the house is 15 Amps or 20 Amps.

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)

My ge microwave model jes1384sf stopped working and sure that the power is going to the microwave, But clock, timer and contol panel etc. nothing turns on. Is there anything can be done to find out what...

You have a power fuse inside of the panel that supplies AC power to the panel as well as the klystron tube. This is generally a slow blow 15 amp Buss fuse. Since these fuses deteriorate over time and they are sized to just hold the requested amps (15) to prevent a possible fire. You will have to take the Panel apart and find the fuse, but be sure you flip the breakers as the panel has a High Voltage power section with large capacitors that can produce a nasty shock. Before touching any thing with the breaker power off, short the capacitors to ground to discharge them, then pull and replace the Buss fuse.

Most of the time while putting stove into the bake setting it will trip the breaker

you need to plug your unit into a power outlet that is fused higher (at least 15 amps) or if the breaker is 15 amps, you may just need to replace the breaker (they do wear out).

GE microwave: model 1840 circuit breaker trips when strarting micro wave


Circuit Breakers do weaken over usage. It is not usually a time factor as much as a load factor. Each time a circuit breaker trips, it loses its ability to carry the same load as it did previously. In other words, a 15 amp breaker only carries the ability to carry 15 amps once. I recommend replacing the circuit breaker with one that has a matching rating. If you do feel up sizing is necessary, check the load rating of the appliances to make sure the additional size really is necessary. Increasing power to appliances that shouldn't need it increases the risks of potential electrical fires and masking real issues. Try changing it with higher amp breakers.

Please accept the solution if it's helpful. Do get back to us for any further query.

What is the wattage?

Hi .. Wattage is a measure of power .. it is the voltage a device opperates at multiplied by the amount of amperage it uses. Sometimes called volt- amps. For an example of this, a 200 watt lamp, on a 120 volt circuit, is using about 1.66 amps. That typical circuit is rated for 15 or 20 amps. The rating is determined by the wire size and the breaker protecting the circuit .. so on my lighting circuit I can install about 8 to 10 of these lights and be safely within the limits of the circuit. For a 1000 watt microwave , on a 20 amp kitchen circuit, this means that the microwave is using about half of the capacity of the circuit. You are charged for your use of electricity by a rate times your usage in kilowatt hours, or how many watts you use, times the hours you are using them.

15A breaker tripping; Is this the right size breaker for the unit?

The breaker is sized according to the size of the wire used in the circuit. The breakers task is to protect the wire from an over current.
The allowed sizes are
#14 wire .... 15 amp breaker
#12 wire ..... 20 amp breaker
#10 wire .. 30 amp breaker
To check if the oven and circuit are compatable .. run an extension for the oven to an outlet outside the kitchen and see if it holds.

My RFS12MPS runs for around 5 secs, and then trips

Sounds like you have a intermittant shorting high voltage capacitor. I have had several of these that check good at rest then short after power is applied then un short by the time you put your meter on it to see if it is shorted. Best suggestion it to substitute the capacitor. The only othe rpossibility is you HV transformer is shorting out. You can completly disconnect the leads to the xfrm and run 120v to the primary. if it draws over 15 amps it is shorted. if it is shorted it could draw up to 30 amps. I would try subbing thecapacitor and if that does not cure it, it is most likely the Xfmr.
