Number Pad Errors

When the pad #5 is pushed 6 shows on the lighted display, When pad #8 is pushed 9 shows on the lighted display. All the other number pad numbers display the proper corresponding numbers. Is there a fix for this.

It's possible that there is a glitch or calibration issue with the specific buttons (#5 and #8) on the keypad. Here are a few steps you can try to troubleshoot the problem:

1. Power Cycle: Start by unplugging the microwave from the power supply for about 1 minute, then plug it back in. Sometimes, power cycling can help reset the electronics and resolve minor glitches.

2. Check for Obstructions: Ensure there are no obstructions or debris around the #5 and #8 buttons. Sometimes, dirt or crumbs can interfere with the keypad's functionality. Clean the area around the buttons gently and see if it improves.

3. Keypad Reset: Some microwaves have a keypad reset option. Check the user manual for your Whirlpool MT4155SPT to see if it provides instructions on how to reset the keypad. If there is a reset function, try performing it and see if it resolves the issue.

4. Contact Whirlpool Support: If the issue persists after attempting the above steps, it's best to reach out to Whirlpool's customer support. They will be able to provide further assistance, guide you through additional troubleshooting steps, or offer information on potential repairs or replacements.

Remember to have your microwave model number and any warranty information handy when contacting customer support, as it may expedite the process. They should be able to help you effectively address the number pad errors you're experiencing.
