Product Details

The Bard 8406-042BX is an OEM proving fan pressure switch designed for use in Bard HVAC systems. This pressure switch monitors airflow by sensing differential pressure at 0.28 inches of water column, ensuring proper fan operation before allowing the system to continue its heating or cooling cycle.

Key Features:

  • Pressure rating: 0.28" water column differential
  • Proving fan switch configuration for airflow verification
  • Genuine Bard OEM replacement part
  • Durable construction for reliable HVAC system operation
  • Used in wall-mount and packaged air conditioning units

This pressure switch is a critical safety component that helps prevent system malfunctions by confirming adequate airflow before the unit operates. Proper airflow verification protects the system from overheating and ensures efficient performance. Always verify compatibility by model and serial number before ordering.

I had tried to cancel an order prior to shipment, but the product still shipped. I have shipped back my product and am waiting on a full refund. Assuming this process goes smoothly, I would rate the customer service 5 stars. My name is Andre Hotard.

Good price for the trailer cover. Easy transaction.

Great!

Works great. Fast shipping. Pleased with the product and customer servies.

So far so good, hope it comes in fast enough. Love the free shipping

Everything was handled in a timely manner. My only gripe is that I wish I had received a confirmation email with a tracking number. I was waiting for it, and then the package just showed up one day. No worries though, as everything came out great. Thank you

Easy to use platform

Good service..

Awesome and easy, great customer service!
