Changing Microwave Tone Generator?

I've opened the control panel and found the tone generator (if that's the proper term). Two spade connector wires going to it and it's mounted on the control board.

Yes tone generator is the correct term

There is room to add a new tone/beep generator on the board while keeping the existing. Need help finding a component that will work.

It is hard to understand how this works without you sharing a picture of the board or mentioning the components you find on top of it. The best way to go from here is to connect the multimeter probes across the spade wires to check for voltage. If you read the voltage only when beeper is active in your oven you can simply replace it with your desired tone generator circuit 

Managed to get a data sheet (PDF) from component suppier. Reading it makes me think this is NOT a tone generator but a relay. If that's the case I don't know which component is making the tone. Again, I have pictures of the circuit board I'd like to post. 

I'd also like to paste the PDF into my reply but can't fiure out how to do this as every button wants a URL. Can anyone help??

Hi peter, there is an option called IMCE (phot frame kind of icon) you can use that and upload the file directly to insert images

A microwave tone generator ,also called a signal generator in some applications is an electronics device that artifficially creates sound frequencies usually ,but not always by a primerily electronic means . The device creates an electrical signal and converters it into sounds. The sounds a tone generator creat very depending on the need of the microwave. Electronic devices such as signal tester utalize simple tone based upon set frequencies to complex assortments of frequencies .

I've looked more closely at the part description on the PDF which includes a circuit diagram for different applications. So a tone generator is not included in this - "Subminminiature High Power Relay" as I had thought. My ears have been deceived as to the location of the tone. All other components on the circuit board are totally soldered in. Exchanging the tone generator would be unworkable.

If you can locate the buzzer then we can do a workaround.

Just remove the buzzer from its place and probe a signal wire, this wire will receive a signal (voltage) only when the buzzer has to go on. You can purchase a new tone generator and trigger it using this signal wire. You also have to find a voltage source and ground point to power your new tone generator. 

I remember my grandpa doing this to increase the notification sound of his toaster
