My microwave clock is set in 24 hour mode and I don't know how to change it to the 12 hour mode

For the Galanz 1.2 cu. ft. ToastWave, GTWHG12BKSA10, you need to press and hold the Clock/Timer pad for 3+ seconds. If needed, press again to switch between 12 and 24 hour clock options. Then rotate the dial until the correct hour is displayed. Press one of the following: the dial, Start or Clock/Timer to save the current hour. Rotate the dial to set the current minutes. Again, press the dial, Start or Clock/Timer to save the current minutes. To exit the clock setting mode, press Stop/Cancel.

HomeDepot has the manual for this microwave/air fryer on the product page: https://www.homedepot.com/p/Galanz-1-2-cu-ft-Countertop-ToastWave-4-in-1-Convection-Oven-Air-Fry-Toaster-Oven-Microwave-in-Black-GTWHG12BKSA10/310997710 . The current link to this manual is https://images.homedepot-static.com/catalog/pdfimages/e8/e87f4420-a777-460f-901f-faa70016a38f.pdf . See page 9 for the directions to set the clock.

I hope this helps. Please add a comment with the model number of your microwave/air fryer if the above steps don't work.

I feel your pain, I am in the same position. After endless mucking around I finally figured it out. By the way, this is for my model P10034AP. Press these buttons: - Cancel [to abort anything currently underway] Clock [to set the time] Cancel [to clear the time allowing input] nnnn [the 4 numbers HH:MM in 24 hour time] Clock [to set the new time]
Hope that helps :) Cheers Jonathan Barton

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.
If you have any other questions regarding your Daewoo KOR-630A, I located an online manual for you.
Cheers!

You can set the clock to a 12 or 24 hour system.
For 12 hour - Touch clock pad once Enter the time using the number digits (1:00-12:59) Touch clock pad again
For 24 hour - Touch clock pad twice Enter the time using the number digits (0:00-23:59) Touch clock pad again

look for the clock or watch symbol on the keypad. When you press it, it will show you a 12 hour(normal time) or 24 hour(army time indication).Select the correct time by pushing the hour then minute buttons. Once that is done, press the clock symbol again whick accepts the setting.

normally you look for the clock ot watch icon. Pressing it once will give you the option for 24 hours setting. Press it twice and it will give you the opportunity to set to 12 hours setting. Using the no. keypad, punch in the time and then repress the clock icon again.

Check the control setup chart on the same page in the middle column.

Press CONTROL SETUP > 3 > 2.
