Description

This pressure switch senses pressure changes and signals the appliance control to start or stop functions, helping restore proper operation when pressure-based controls fail. It's a direct-replacement style switch used in compatible Frigidaire appliances. What it does:

• Detects and closes or opens an electrical circuit based on air or water pressure changes
• Signals the control board to advance cycles or enable components (pump, valve, blower)
• Common symptom indicator: appliance won't complete cycles or responds inconsistently when pressure-controlled
• Helps stop operation when pressure limits are reached to protect system components

What's included:

• One pressure switch

Install notes:

• Disconnect power (and water, if applicable) before starting work
• Handle the switch and its terminals with care; avoid bending pins or cracking the housing
• Inspect and replace any associated tubing or fittings that are cracked or clogged
