Cross Reference Information

Part Number DA81-08336A replaces AP7021189, 5707440200.

Description

A small reed-style switch used on the appliance service/control card to detect magnetic fields and signal the control board. Replaces a failed reed sensor to restore the card's ability to sense door/magnetic inputs and related functions. What it does:

• Acts as a magnetic sensor on the service/control card to open or close an electrical contact when a magnetic field is present
• Helps the control board detect door or service-mode magnetic triggers and change operating state
• Common symptom: unresponsive door/magnetic sensing or intermittent card input detection
• Electromechanical component — replaces a faulty reed sensor to restore reliable switching

What's included:

• One service card reed switch (single reed sensor as shown)

Install notes:

• Intended for PCB-level replacement on the service/control card; inspect board for damage before installing
• Handle board and components with ESD precautions; disconnect power and discharge capacitors before servicing
• Use correct soldering technique for small components; avoid excess heat to prevent board damage
