If you find your Frigidaire microwave buttons not working, it can interrupt your daily routine and cooking plans.

This guide aims to help you troubleshoot and resolve the problem, ensuring your microwave is back in perfect working order.

From basic checks to potential fixes, we will explore various solutions to get your Frigidaire microwave operational again.

Key Points

• Check the Child Lock Feature: Ensure child lock is disabled for operation.
• Inspect the Control Panel: Look for visible damage or wear on buttons.
• Reset the Microwave: Unplug the unit, wait, and then reconnect.
• Examine the Power Source: Verify if the microwave is properly plugged in.

• Consult the Manual: Refer to the user manual for model-specific troubleshooting steps.

Understanding The Problem

1. Common Causes of Button Failure in Frigidaire Microwaves

1. Worn-Out Membrane Keypad: Over time, the membrane keypad can wear out, causing buttons to stop responding. This is a common issue in older models.
2. Control Board Malfunction: The control board acts as the brain of your microwave. If it malfunctions, the buttons can stop working.
3. Loose or Damaged Ribbon Cable: The ribbon cable connects the control board to the keypad. If it becomes loose or damaged, the buttons may fail to respond.
4. Electrical Issues: Power surges or faulty wiring can lead to electrical issues that affect the functionality of the buttons.

2. Identifying the Issue

Before diving into troubleshooting, it’s important to identify whether the problem lies with the control panel or the buttons themselves. Here’s how:

• Inspect the Keypad: Press each button individually to see if any respond. If certain buttons work while others don’t, the issue may be with the membrane keypad.
• Check the Display: If the display is blank or shows error codes, the problem might be with the control board.
• Listen for Beeps: If the microwave beeps when buttons are pressed but doesn’t respond, the control board could be malfunctioning.
