Unplug the power cord of the Frigidaire washing machine before attempting to replace the belt.
Locate the screws on the bottom of the front panel, unfastening them with a screwdriver, and lift the front panel from the bottom to unhook the top from the metal clips.
Remove the front panel from the washer cabinet, setting it out of the way, and locate the idler arm and motor at the bottom of the washer.
Move the idler arm forward by hand to relieve the tension on the belt, and remove it from around the motor and transmission pulleys. Discard the belt.
Place the new belt around the motor and transmission pulleys, allowing the idler arm to move back into position to add tension to the belt.
Attach the front panel to the metal clips at the top on the front of the cabinet, and secure the bottom of the panel with screws.
Plug the power cord of the Frigidaire washing machine back into the electrical outlet.
