Parts for Ge DDC4400AEL: 02 - Timer Assembly Parts

This 2-terminal pressure switch controls air/fan-related pressure sensing to help the appliance detect vent or airflow conditions and run safely. It replaces a worn or failed switch to restore proper pressure sensing. What it does:

• Opens or closes an electrical circuit based on measured air or vent pressure.
• Allows the control board to detect proper airflow or closed pressure states.
• Commonly linked to symptoms like no-start, blower not running, or error codes indicating pressure/fan faults.
• Acts as a safety interlock to prevent operation under incorrect pressure conditions.

• One pressure switch (5000P-AD), 2-terminal.

• Disconnect power before inspecting or replacing the switch to avoid shock or injury.
• Verify tubing and electrical connectors are clean, undamaged, and routed per the appliance layout.
• Match the switch terminals and mounting orientation to the original part; do not force connectors.
