Disconnect the Frigidaire electrical cable from the power outlet, which is typically inside the overhead cabinet.
Unscrew and pull out the screws inside the bottom of the cabinet above the Frigidaire, using the screwdriver, while your helper supports the appliance from below.
Pull the bottom front edge of the Frigidaire upward while raising the appliance to disengage the support hooks on the rear from the slots in the bracket on the wall.
Lower the Frigidaire slowly to the range surface while guiding the electrical cord out of the hole in the bottom of the cabinet.
