Frigidaire Oven Control Knob Replacement - Signs & How-To

Q: What does Frigidaire Oven Control Knob Replacement - Signs & How-To mean?

Broken, loose, or missing control knob prevents reliable heat adjustment. Replacing the knob restores full burner and oven control.

Frigidaire Oven Control Knob Replacement — What This Part Does

The control knob is the plastic or metal dial you turn to adjust burner heat or oven temperature. It fits over a D-shaped or round shaft on the front panel control switch (infinite switch for burners, selector for ovens). When you rotate the knob, it turns the underlying switch stem to change heat output or activate oven functions.

Knobs fail when the internal D-shaped opening cracks, strips, or wears out so they no longer grip the shaft. Physical damage from cleaning, impacts, or heat exposure can break the knob body. A mismatched replacement knob that does not fit your shaft size will feel loose or spin freely. Even a good knob will not work correctly if the underlying control shaft itself is bent or worn.

How to Replace It

Disconnect power at the circuit breaker or unplug the range from the wall outlet.
Pull the old knob straight off the control shaft by gripping it firmly and pulling toward you (no screws or fasteners hold it).
Inspect the knob for cracks in the hub or stripped D-shaped opening and check the metal shaft for bends or wear.
Locate your model and serial number on the label inside the oven door frame or on the back panel of the range.
Order the correct OEM replacement knob using your model number (common Frigidaire part numbers include 316223002, 318196633, and 316025107).
Align the flat side of the D-shaped opening in the new knob with the flat on the control shaft.
Push the knob straight onto the shaft until it is fully seated and flush against the front panel.
Turn the knob through all positions (off to high for burners, off to bake/broil for oven) to confirm smooth operation and correct alignment with the markings.
If the knob still feels loose or spins freely, inspect the control shaft closely and consider replacing the underlying burner switch or oven control assembly.

When to Call a Pro

Call a technician if the new knob still wobbles or spins after installation, which usually means the control shaft or the underlying infinite switch (burner control) or selector switch (oven control) is damaged and needs replacement. Any work involving gas line disconnection, burner valve replacement, or control board replacement behind the panel should be handled by a qualified appliance repair pro or gas technician. For gas line, burner, or igniter work, or if you ever smell gas, stop and call a licensed technician.
