This oven thermostat senses and regulates oven temperature so food cooks evenly and the range reaches set temperatures. It replaces a failed temperature control to restore accurate heating and cycle behavior. What it does:

• Closes and opens the control circuit to maintain the oven at the selected temperature
• Can correct symptoms such as oven not reaching set temperature, overheating, or excessive cycling
• Works with the oven's control system and heating elements to stabilize bake and broil operations
• Mechanical design — avoid bending or damaging the sensing element/capillary

• One oven thermostat

• Disconnect power to the appliance before starting any service
• Handle the thermostat and sensing element carefully; do not kink or sharply bend the capillary
• Verify proper thermostat mounting and oven cavity seals for accurate temperature control

Indicator light replaces the control-panel lamp that signals power or active functions, restoring visible status feedback for safer, more confident operation. Use this when the original lamp is dim, cracked, or fails to illuminate. What it does:

• Provides visible indication of power, cycle status, or selected functions on the appliance control panel.
• Restores clear status feedback when the original lamp is burned out or flickering.
• Helps troubleshoot whether a control or circuit is receiving power by showing when the indicator should be lit.
• Improves usability so settings and operating states are easy to confirm at a glance.

• Disconnect power to the appliance (unplug or turn off the breaker) before beginning work.
• Access may require removing the control panel or console.
• Handle the lamp carefully and avoid touching bulb surfaces; use gloves to prevent oil transfer.
• After installation, restore power and verify the indicator lights as expected; if it still does not light, further electrical diagnosis may be needed.

The Rocker Switch is an OEM part for Frigidaire ranges and ovens. It is responsible for turning the interior oven light on and off. The light switch allows visibility of the oven cavity for viewing food during the cooking process.

Causes can include normal wear and tear over time, exposure to heat inside the oven cavity, or accidental damage.

Symptoms of a bad oven light rocker switch include:

• The oven light failing to illuminate when the door is opened
• The light remaining on even when the door is closed
• An inconsistent or flickering oven light
• The switch itself becoming loose, cracked, or non-responsive

This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.

• Replaces a damaged or missing control knob so you can accurately set burner/oven temperatures or functions
• Fits standard stove/oven control shafts (push-on style) for a secure, tactile grip
• Helps eliminate loose, hard-to-turn, or non-indexing knobs that affect control
• Restores original appearance when the factory knob is faded, chipped, or broken

• One graphite control knob

• Typically installs by pulling off the old knob and pushing the replacement onto the control shaft; no special tools required
• Verify knob alignment and function before use; do not force onto the shaft if it does not seat easily
• Disconnect power or ensure controls are off and burners/oven are cool before replacing to avoid injury

The Surface Unit Switch Kit is an OEM part for Frigidaire ranges. It controls the power and heat levels to the surface burners on the cooktop, allowing you to adjust the temperature for cooking. This kit typically includes the necessary components to replace a faulty switch and restore proper functionality to the burners.

Causes of a bad surface unit switch can include electrical malfunctions, wear and tear from regular use, or damage due to spills or impacts. A faulty switch can prevent the burner from heating correctly or at all.

Symptoms of a bad surface unit switch include:

• Burners not heating up or heating unevenly
• Inability to adjust the burner temperature
• Burners not turning on or off properly
• Sparks or electrical odors near the switch

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.

This truss-head machine screw secures a switch to its mounting bracket or panel. Replacing a worn or missing screw restores a solid, aligned switch fit for reliable operation.

• Fastens the switch body to a bracket or chassis panel
• Helps keep the switch aligned for consistent actuation
• Replaces stripped, corroded, or missing mounting hardware
• Common symptoms: loose or wobbly switch, misalignment, rattling or vibration around the switch area

• Disconnect power to the appliance before servicing
• Start threads by hand to avoid cross-threading; tighten snugly without overtightening
• Verify thread size and length match the original hardware
• If multiple screws secure the switch, replace them in a consistent pattern to maintain alignment
