Parts for Frigidaire FFBN1721TV0: System Parts

This electronic control board is the appliance's main control module that manages timing, temperature, and user-interface commands so the unit operates correctly. Replacing a faulty board restores proper control and display function. What it does:

• Receives inputs from the front panel and sends signals to heating elements, fans, and other components
• Manages oven/range timing, temperature regulation, and cycle sequencing
• Common symptoms of a failing board: display or clock blank, controls unresponsive, incorrect cycles, or intermittent operation
• May click, burn, or show visible damage when failed

• Disconnect power at the breaker before service to avoid shock or damage
• Handle the board carefully to avoid static discharge; use anti-static precautions if available
• Verify wiring connections match the replacement board and reference the appliance wiring diagram

A water inlet valve that controls water flow to the refrigerator dispenser and icemaker, restoring proper fill and preventing intermittent or no-water delivery. Use this valve when water stops flowing or the icemaker won't fill. What it does:

• Directs incoming water to the dispenser and icemaker when activated
• Opens and closes to regulate water flow for filling cycles
• Commonly replaced for symptoms like no water at the dispenser, icemaker not filling, or weak water flow
• Helps stop intermittent filling that can be caused by a stuck or leaking valve

• Disconnect power and shut off the water supply before starting work
• Verify inlet and outlet fittings, electrical connector orientation, and mounting before removal
• Use basic hand tools; handle solenoid and valve body carefully to avoid damage

This capacitor stores and releases electrical energy to help a motor or compressor start and run smoothly. Replacing a weak or failed capacitor can restore proper startup, reduce humming, and improve overall cooling performance.

• Provides the phase shift and torque boost needed for AC motors to start
• Stabilizes motor operation during run for consistent performance
• Common symptoms of failure: motor/compressor hums but won't start, intermittent starting, reduced cooling/airflow
• Visual clues include a swollen/bulging top or leaking oil residue
• Contribute to breaker trips or overheating when degraded

• Disconnect power and safely discharge the old capacitor before handling
• Photograph wiring and transfer leads to the matching terminals on the new capacitor; match microfarad (µF) and voltage ratings to the original
• Mount securely; avoid contact with sharp edges or moving parts
• Check the motor/compressor and wiring for additional faults
