Shut off the circuit breaker that controls the Frigidaire stove. By cutting power at the breaker, you do not have to move the appliance to reach the power cord in the back.
Open the Frigidaire door to locate the screws at the top of the frame where the cabinet attaches to the smooth stove surface. Remove and save these screws.
Raise the top of the Frigidaire at an angle, back toward the rear of the stove. Hold the top above the stove with support from a metal rod or wooden dowel braced between the top and the frame of the appliance.
Take out the Phillips-head screws on the bracket under the smooth top for the element you plan to replace and set aside the bracket. For example, if the right front element is burned out, take off the bracket in the upper right corner of the smooth top, when viewing from below.
Pull the defective part out of the electrical socket straight back, without twisting.
Plug in the new element to the socket and reattach the bracket over the element with screws.
Remove your metal or wooden rod support and lower the top so it rests on the Frigidaire cabinet.
Secure the top to the front edge of the Frigidaire stove using the screws you saved earlier.
Raise the door to the closed position and flip the circuit breaker back on.
