This fixed metal resistor (designation "F") is a replacement electrical resistor used on control and power assemblies to maintain correct current flow in the circuit. Replacing a failed resistor restores proper circuit function and helps the appliance operate reliably. What it does:

• Limits or stabilizes current in the control/power circuit to protect components
• Failsafe symptom: appliance control errors, loss of specific function, or intermittent operation
• Often located on or near control boards or power modules where it regulates voltage/current
• Used when a resistor shows open, shorted, or out-of-spec resistance during diagnosis

• One fixed metal resistor (marked "F")

• Disconnect power to the appliance before any service to avoid electric shock
• Verify resistor value and polarity (if applicable) with a multimeter before replacement
• Handle boards and components with ESD care to avoid damage

Replacement mounting screw for microwaves and wall ovens. Secures internal components and panels. Order a new screw if yours is stripped, missing, or lost.
