I'm trying to find a phone number for service or technical support for my Galanz microwave.

They are usually at the rear where the power lead goes in. This will state the maker, the address, the voltage and watts, the model number and serial number. That is a statutory requirement. In some circumstances they are in the door frame rebate but not so common where heat is involved.

Unfortunately I did not see the model number you provided listed here. However they do provide manuals for their products and if you select a model that is similar to yours you might find the available manual to be useful.

You might have a little trouble with this one. But all I can suggest is sending an email
to them and ask for the manual. They should have a pdf version online but I don't read
any Chinese so can give you that directly. Most household goods companies tend to
respond within a few days about manuals.

Sounds like you have a bad membrane keypad.

Galanz's website seems to be useless. I tried finding information but kept being told "no data available." So while I can't tell you where to find the manual, here's something to try. Most microwaves get put into lock by pressing and holding one of the buttons for longer than normal, or by pressing one of the buttons several times in a row. Some ovens use the TIMER button. It won't be one of the number keys, but one of the function buttons. So start with a button, press and hold it for at least 5 seconds before you let go. If nothing happens then try another button. If that doesn't solve the problem, then try pressing each function key several times before moving on to the next one. If that still doesn't get it going, maybe a store in your area that sells Galanz will take a look at the book for you. The process should be the same for any similar model.
