Laars Heating Systems RE0240900 Pressure Switch
The Laars Heating Systems RE0240900 Pressure Switch is an essential OEM component specifically engineered for precise HVAC pressure monitoring in Pennant Pool Heaters and high-efficiency hydronic systems. This SPDT pressure switch features a critical .75" WC (Water Column) set point, ensuring the unit only fires when the blower or exhaust system achieves the necessary static pressure for safe combustion. Built with a Single Pole Double Throw configuration, it provides a versatile electrical interface for safety circuit integration, allowing for both normally open and normally closed operations depending on your control board's logic requirements. Whether you are performing a boiler pressure switch replacement or troubleshooting a pool heater ignition failure, this part offers the mechanical reliability needed to prevent short-cycling and ensure long-term system stability. As a Laars genuine part, the RE0240900 maintains the original equipment’s specifications, critical for adhering to combustion safety standards in commercial and residential mechanical rooms.
Key Benefits:- Precise .75" WC Calibration: Accurate set point prevents burner operation under insufficient airflow conditions, protecting the heat exchanger.
- SPDT Electrical Versatility: The Single Pole Double Throw design supports a wider range of HVAC control board configurations.
- OEM Compatibility: Exact Laars RE0240900 replacement ensures seamless fitment without the need for mounting modifications or bracket fabrication.
- Durable Construction: Engineered to withstand the high-temperature and high-humidity environments typical of pool heater enclosures.
What are the symptoms of a failing pressure switch in a Laars Pennant heater?
Technicians typically observe a "no-ignition" state where the blower runs but the gas valve never energizes. A diagnostic multimeter test showing an open circuit across the RE0240900 terminals during induction usually confirms the diaphragm has failed or the set point is no longer being reached.
Can I use this switch for both positive and negative pressure applications?
Yes, given its SPDT configuration and .75" WC rating, it is suitable for draft proving or blocked vent detection in systems requiring this specific water column threshold.
Is this switch compatible with other Laars Series?
While primarily designed for the Pennant series, this 0.75-inch WC pressure switch acts as a universal replacement for any Laars or Teledyne Laars system calling for this specific pressure rating and footprint.
