Quasar Microwave buttons not working

When your Quasar microwave buttons are not working, the touchpad and control panel are the most likely cause, especially if some buttons respond while others do not. Press each button to compare their response. If only certain buttons are unresponsive, replace the Quasar microwave touchpad and control panel or the touchpad, depending on your model. If the microwave buttons are unresponsive, the user control and display board is the next likely cause. When none of the microwave keypad buttons work correctly, the main control board may be defective. A faulty control panel is less common but can also prevent the buttons from responding. Before ordering, enter your model number to find the exact replacement part for your specific Quasar microwave. Replacing a touchpad or control panel may require opening the outer cabinet. Unplug the microwave first, and remember that the high-voltage capacitor can store a lethal charge even after the microwave is unplugged. The capacitor must be properly discharged before any interior work, so use a qualified technician if you are not familiar with safe capacitor discharge procedures.

07 - Quasar Microwave Switch Holder

The microwave switch holder is the component that houses the door switches behind the control panel. If the switch holder is damaged or misaligned, one of more switches may not be actuated when the microwave door is closed, which may prevent the buttons on the control panel from functioning. You will need to uninstall the control panel and inspect the switch holder to confirm it is in good condition and secured properly. Replace the switch holder with a new one if necessary.
