Disconnect your Frigidaire stackable washer and dryer combination from the electrical wall outlet.
Find the two screws beneath the combination control panel. These screws hold the angled panel between the washer and dryer to the cabinet.
Remove the screws from the angled panel. Lower the panel, and pull it from the cabinet. Removing the panel exposes the screws holding the control panel onto the unit.
Remove the two screws from the bottom left side of the control panel. Take the two screws from the opposite side. Pull the control panel forward, and allow the wires that connect the panel to the unit to support it.
Find the small black box to the left of the washer control. The buzzer connects to the control panel with two wires. Grab the spade terminals on the ends of the wires with needle nose pliers. Gently pull the wires off the buzzer’s connectors.
Remove the one or two screws holding the buzzer to the control panel. Take out the old buzzer, and install the new buzzer in the same location. Slide the spade terminals connected to the ends of the wires over the terminal connectors on the new buzzer.
Locate the dryer buzzer to the right of the dryer timer control in the console. Repeat the steps for replacing the washer buzzer in order to replace the dryer buzzer.
Fit the console panel back onto the face of the Frigidaire stackable washer and dryer. Replace the four screws you removed previously to secure the panel to the unit.
Replace the angled panel between the washer and dryer. Reconnect the unit to the electricity.
