Oddly, the owner's manual doesn't say.

You can contact GE customer service here, or if it's working properly, here's a test that will tell you how much output power it has:

MICROWAVE HEATING POWER TEST

The following test will provide a suitably accurate measurement of the output power of any microwave oven. Variations or errors in performing this test will produce uncertain results. If the line voltage (from the electrical outlet) is low, the magnetron output will be correspondingly low.

Equipment needed:

- Microwave safe container with 1000 mL (1 Liter) gradation.

- Fahrenheit or centigrade thermometer

Procedure:

Pour exactly 1000 mL (1 Liter) of cool tap water into the container. Using the thermometer, stir the water, then measure and record the temperature. For accurate results the water should be about 60 degrees F (20 degrees C).

Place the container on the center of the oven cooking shelf (do not leave the thermometer in the container and remove any metal racks), and heat the water (at full power) for 63 seconds. Use the second hand of a watch, not the oven timer.

After the heating time is completed, immediately remove the container, stir the water, re-measure and record the temperature of the heated water.

Subtract the starting water temperature (step 2) from the ending water temperature (step 3) to obtain the temperature rise.

To determine the output power in watts, multiply the total temperature rise by a factor of 38.75 if you're using a Fahrenheit thermometer or by 70 if you're using a centigrade thermometer.

Product is GE Microwave (Spacesaver-type) JNM1731DM1BB. New surface light bulbs installed. Unable to turn them off or change from bright to dim


Bottom lights are controlled through relays on the main control board which is mounted on the back of the touch pads (control panel).You can check and see if wires are touching each other on the board but my guess is the board is defective and needs replaced.

For model JNM1731DM1BB, there's no reset. Your membrane keypad is failing and has to be replaced.

On this model, the membrane keypad is not available as a separate part, so you would have to order the control panel frame assembly which comes with a new keypad.

In this case, you simply move your circuit board into the new frame. That is a simple do-it-yourself job.

It is part number WB07X11033 and you can order it from the Pros here for $148.66 (subject to change).

You can find helpful exploded view diagrams and order other parts at that link, too.

There is a video here showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you unplug the keypad (as per the photo below) and move your circuit board into the new frame.

Be careful, the display is made of glass.

Shorted out microwave when i tried tochange lightbulb. GE model jnm1731dm1bb, where is the fuse located?


The fuse is probably located behind the grille, and it may again be behind a small panel behind the grille. Look for the fuse label when you get the grille off.

There is a video here which shows you how to remove the grille.

But chances are good that you also damaged the circuit board when you removed or inserted the bulb without first unplugging the oven, as it says on the label by the light socket.
But that can usually be repaired economically repaired.
Or you can order and install a new smart board.
For model jnm1731dm1bb (also called JNM1731DMBB01) it is part number WB27X10933 and you can get it from the Pros here for $151.56.

There may be a short in the keypad, or it is the microcontroller board.

Can not determine the wattage of the microwave we bought. It is a GE microwave model #JNM1851DM4BB


There is no reference to this model on the GE website, but have a look at this webpage:

http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?Name=340104_jvm1851bhchshwh_r3.pdf&RequestType=PDF

The wattage of this model JVM1851 is 1100W.

If the model is a counter top unit, you can check whether there is a plate at the back of the oven with the wattage on it.
