Re: KOR-630A how do disable sound?

The only way to do this is to locate the piezo sounder on the control board & remove it. However, I do not recommend trying to do this yourself, unless you are trained & experienced in high voltage electronics, as there are INSTANTLY LETHAL voltages present inside, even if the unit is off & unplugged. The sounder is a black, cylindrical device with a small hole in the middle. It will be found on the printed circuit board behind the keypad, mounted either horizontally or vertically. There will be either 2 or 3 connections to the sounder.

Can this be fixed by me?

Could be a bad door switch or a bad relay. With the door closed try gently pushing it up and down if at some point the unit fires up, one of the door switches is not making contact. As for the relays they are on the circuit board, but not replaceable unless you are very good at De-soldering. Also keep in mind microwave units have very high very deadly voltages stored in the capacitors 4000V that can easily kill so don't mess with them unless you know what you are doing!

How do I change the time on my Daiwoo microwave?

  1. Touch the CLOCK pad. This will activate the 12-hour system. (To activate 24-hour system, tap once more)
  2. Enter the correct time of day by touching the time set panels.
  3. Touch CLOCK pad.
You will know that you're changing the time when your display stops blinking and and the colon starts blinking.
