Utica Boilers 240007140 Normally Open Pressure Switch 0.14 Inches Wc

Product Description

The Utica Boilers 240007140 is a normally open pressure switch designed for use in HVAC systems and pneumatic control systems. This switch monitors air pressure and responds when pressure reaches its set point of 0.14 inches water column. When pressure rises to that threshold, the switch closes the circuit and signals the system to take action. When pressure drops below the set point, the switch returns to its open state, keeping the circuit open until the condition is met again.

This type of pressure switch plays a critical role in boiler and air handler operation. It confirms that the draft inducer or blower motor is producing adequate airflow before allowing ignition to proceed. Without a functioning pressure switch, the control board will not allow the burner to fire. This protects against dangerous conditions like blocked flue passages or failed inducer motors. HVAC technicians rely on pressure switches as a first diagnostic checkpoint when troubleshooting ignition lockout faults.

The 240007140 uses a single pole single throw normally open contact configuration, abbreviated SPST-NO. This is the standard configuration for proving switches in heating equipment. The compact design allows installation in tight equipment cabinets where space is limited. It is built for the demands of residential and light commercial heating systems where consistent, reliable operation is required across many heating cycles. Replacement of a faulty pressure switch is a common service call, and having the exact OEM part number ensures a proper fit and function without modification.

• Normally open SPST-NO contact configuration for standard proving switch applications
• Set point of 0.14 inches water column for accurate air pressure detection
• Compact design fits in tight installation spaces inside boiler and air handler cabinets
