Whirlpool Ice Maker Optic Emitter & Receiver Control Board Parts — Models & Compatibility

Your ice maker suddenly stopped working — or worse, it's dumping cubes nonstop into the bin. The optic emitter and receiver control board is the eye of your ice maker system, and when it fails, ice production goes haywire. This replacement kit (4389102) fits over 100 Whirlpool, KitchenAid, Kenmore, and Maytag refrigerator models.

Is This the Right Part for Your Model?

Before ordering, verify your model number. You'll find it inside the fresh food compartment on the left or right wall, or sometimes on the ceiling. It's typically a sticker with a model number like ED5FHAXSL02, KSRG25FVMS01, or 10659963804. Cross-check it against the compatibility list below — this board kit replaces original part numbers W10757851, W10290817, 2198586, and AP5956767.

About This Replacement Part

The optic emitter and receiver board sits inside your ice maker assembly and uses an infrared beam to detect when the ice bin is full. When this board fails, you'll see one of three symptoms: no ice production at all, ice maker won't stop dispensing, or the unit cycles constantly but never makes ice. It's a common failure point in Whirlpool-family refrigerators built between 2010-2018, especially in high-humidity environments where condensation can damage the optical sensors.

What's Included in This Kit

The 4389102 kit contains the complete optic emitter and receiver board assembly. It's a direct replacement — you're swapping the entire optical sensor unit, not individual components. The board comes pre-assembled and tested, which means you don't need to transfer tiny sensors or worry about alignment issues.

Common Questions

Will this fix my ice maker that won't stop making ice?

Yes, if the optical sensor is malfunctioning. When the emitter/receiver can't detect a full bin, it keeps cycling. Replacing this board restores proper bin-level detection.

Do I need to replace the entire ice maker?

Not usually. If the mechanical parts (motor, mold, rake) still work and only the optical sensor failed, this board kit solves the problem at a fraction of the cost of a complete ice maker assembly.

How do I know if it's the control board or something else?

If your ice maker makes a harvest cycle sound but produces no ice, check water supply first. If water flows but ice production is erratic or the bin overfills constantly, the control board is the likely culprit.
