Customer Questions and Answers for Noise Filter (Emi/Rfi) by Frigidaire

This line noise filter conditions incoming AC power by reducing electromagnetic interference before it reaches the appliance's electronics. Replacing a shorted or damaged filter can restore stable operation and help prevent erratic control behavior.

• Filters EMI/RFI on the power line before it reaches the control system
• Helps protect sensitive electronics from interference and voltage spikes
• Failure may present as no power, intermittent resets, or nuisance GFCI/breaker trips
• Typically mounted near the power-cord entry; also called a line filter

• Disconnect power and allow any capacitors to discharge before servicing
• Note wire positions and line vs. load orientation; take a photo before removal
• Secure the ground and mount the new filter firmly to the chassis
• Route and reconnect wires carefully to avoid pinching; reassemble and test
