Panasonic Microwave Buttons Not Working. There is absolutely no doubt about the fact that Panasonic microwaves are one of the most used appliances in a kitchen.
The reasons behind this are many and interlinked, but our main reason for posting this blog is that microwaves can sometimes behave strangely.
For example, they tend to break down during routine use due to certain issues which are primarily associated with Panasonic microwaves.
These touchpads or buttons might have a worn-out electrical board or be defective, to begin with. As a result, people face immense difficulties when using the microwave oven. However, we’ll make sure that you learn how to fix this problem right here.
Panasonic Microwave Buttons Not Working
This article discusses some issues with Panasonic microwaves when their buttons don’t work.
Control Board Malfunction
When your microwave’s most commonly used buttons stop working, one reason could be a defective membrane switch. If the touchpad isn’t responding but the display is on, it’s likely that a problem with your control board may exist.
An electrical current is generated by the control board and then fed to the membrane switches. If the power board doesn’t generate enough current, you will likely need to replace it. Disconnect the main supply wire and remove the cabinet before trying to replace the power control unit yourself.
Defective Membrane Switch
Another possible reason why microwave buttons aren’t working could be an issue with the membrane switch. This more specifically goes by the name of a touchpad and has a few electrical switches on it which are all made out of that specific soft-touch coating.
There’s also a conductive coating on this switch which can go defective with repeated use. If this is the case, you may need to unplug the appliance and remove its cabinet.
Check the membrane switch for continuity using a multimeter. If pressed with something flat yet firm, the resistance should be within several ohms. If not, you might need to get it replaced.
Faulty Control Panel
Sometimes our microwaves will not work as expected, for several reasons. The most common culprit of these malfunctions is often the microwave’s control panel, which can become defective.
If this happens to your device, follow these steps to find out if your microwave’s control panel is malfunctioning, and if it is, what you need to do next.
First, press each of the buttons on the control panel by hand. If some of these buttons work but not others, that means the unresponsive buttons are broken.
Nevertheless, if all of the controls are not working, we recommend you purchase a new touchpad and control panel.
Error In Touchpad
To determine if the touchpad is defective, unplug or disconnect the device from its power source and open it up, then press each of the buttons.
If some of the buttons respond appropriately and others do not repeat this process for all of the buttons on the external casing.
If no buttons are responsive to any extent, you might want to call out an expert electrician to find out what’s wrong with your touchpad. Alternatively, replacing your touchpad may be a viable solution.
FAQs
What is wrong with the Start button on my microwave?
In some microwaves, the door interlock mechanism includes a number of micro switches that prevent the microwave oven from producing heat if the door isn’t closed properly. If your microwave is experiencing issues with starting or cooking food correctly in general, you may have a broken switch. Be sure to check that each entry is correctly entered before hitting the start button.
Otherwise, it will not be counted as one of the three entries required which should make this behavior occur on your microwave’s control board.
What is the procedure for resetting a microwave keypad?
Keep pressing and holding the Start/Enter button together for approximately 4 seconds. If the L icon or red lock doesn’t disappear from your microwave’s display, you may need to reset your microwave. After unplugging the unit, you can plug it back in after two or three minutes.
Once plugged back in, be sure to give the microwave a few more tries before giving up on its use entirely.
