This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside.

This can be caused by slamming the door or by habitually opening the door while it's cooking without hitting the Stop pad first.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa:

How do you set the power level? The model number is: JVM1730DM1WW The serial number is: MM901698B

Assuming your touch pad is working properly, press Time Cook (for cooking) or Time Defrost (for defrosting) and then type in the length of time that you want the microwave to operate. Then press Power Level and type in a number from 1-10. Finally press Start. Depending on the GE microwave, the Power Level button may be above 2 or to the left of 0. (I've seen both keypad designs depending on when and where the microwave was manufactured.) If you press Power Level before setting the cooking time, the unit will reset when you press Time Cook or Time Defrost.

GE has the manuals for some of their microwaves on their site. See and enter the model number in the search engine.

I hope this helps.

My mother just bought an Emerson MW8119 Microwave and can't figure out how to only set say 15 seconds cook time. Is it possible?

Hi! I just purchased the same microwave, and came online to find the solution. I was then able to find the correct answer to this problem. On this model, Emerson does not put a "time cook" button for odd cook times such as 15 seconds. Instead, they have you push the "Power Button" prior to setting the cook time.

If you want to cook on full power, press the power button once, and then enter your cooking time and press start. If you want to cook on 50% power or 30% power or something like that, push the "Power Button" several times until the appropriate power level is displayed, then enter the cook time and press start.

The reason that it starts up right away when *********** pushes the 1 button is because Emerson has the quick cooking feature for 1 minute through 6 minutes. You only have to push the number once to get the 1 minute cook time or anywhere through 6 minutes respectively.

Hope this helps!

Viking microwave has digital lights but will not turn on to cook?

Hi the problem will be with the touch panel membrane or the controller. if yoiu can hear a click when the start button is pressed then the touch panel is OK asnd you should look at the controller which can be replaced as a unit or if you are up to it it's probably the main cook relay that has failed.
