Why is my microwave #2 button say #3 when I press as wrong number? Also when I press auto reheat button it automatically go to potato mode instead of castrolle. Since #2 button said #3, I cannot set time as pm anymore. Just started this issues a month ago. I unplugged and plugged it back on and still have issues. Any suggestions? Please.

Cause 1

Touchpad and Control Panel

To determine if the touchpad and control panel are defective, try pressing each of the buttons on the control panel. If some of the buttons respond correctly while others don’t, replace the touchpad and control panel.

Cause 2

Touchpad

To determine if the touchpad is defective, try pressing each of the buttons on the control panel. If some of the buttons respond correctly while others don’t, replace the touchpad.

Cause 3

User Control and Display Board

To determine if the control and display board is defective, try pressing each of the buttons on the control panel. If none of the buttons are responding correctly, replace the user control and display board.

Here's how to remove the panel, finding the part may be harder:

Samsung mw73ad-b/xtl . Only clock button and its minute & hour button respond. The minutes and hour button serve the dual purpose of setting time for 1 minute or 10 minutes. They do not respond except while setting time. Rest of the buttons are not responding

I’ve replaced my control panel and touch pad and still have buttons that don’t respond the main one being the start button. Is there anything else that can control this?

It may not be necessary to replace the touchpad and the control panel. You can take a blow dryer move it back-and-forth over the pads that don’t work, and keep pressing the pad up and down. they may come unstuck. This has worked for mine on several occasions. What happens is when you’re cooking the grease Will cause them to stick over time. Give it a try before you throw everything away.
