Lennox 88M98 Pressure Switch

Lennox 88M98 Pressure Switch

As a seasoned technician, you know that a failing low pressure switch can lead to catastrophic compressor burnout or system freezing. The Lennox 88M98 Pressure Switch (also identified by factory part 100087-03) is a critical safety control designed for precise refrigerant pressure monitoring in residential and commercial units. This OEM Lennox replacement part features a factory-calibrated set point that actuates at 90 PSI and provides an auto-reset at 40 PSI, ensuring the system shuts down before low-suction conditions cause permanent damage. With its 1/4" SAE female flare connection and 45-inch lead wires, it allows for a direct-fit installation in tight service panels without the need for additional field-fabricated harnesses. The single-pole, single-throw (SPST) configuration is rated for 120/240VAC applications, making it a versatile component for HVAC system protection across various Lennox furnace and heat pump models. For contractors looking for the latest technical updates, please note that this component has transitioned to the Lennox 15C83 in newer production runs, though the 88M98 remains the standard for maintaining original equipment specifications.

Key Benefits for HVACR Contractors:

  • Direct OEM Compatibility: Engineered specifically for Lennox HVAC units to ensure the internal resistance and response times match factory safety protocols.
  • Rugged Gold Flash Contacts: Designed to prevent oxidation and ensure reliable electrical continuity even in high-cycle environments.
  • Prevents Compressor Failure: Rapidly detects loss of charge or restricted airflow to prevent low-pressure trip conditions from damaging the motor.
  • Simplified Installation: Features 45-inch leads and a standard 1/4" flare nut for quick field replacement during emergency service calls.

Common Questions:

What are the specific trip and reset points for the 88M98?
This switch is calibrated to actuate (cut out) when system pressure reaches 90 PSIG and will automatically reset (cut in) once the pressure drops back to 40 PSIG.

Is the 88M98 compatible with R-410A systems?
Yes, this low pressure control is rated for use in systems utilizing HFC-410A as well as older R-22 legacy equipment, provided the PSI requirements match the unit's nameplate specifications.

Can I use the Lennox 15C83 as a substitute?
Yes, the Lennox 15C83 is the official manufacturer-designated replacement pressure switch for the 88M98, maintaining the same electrical ratings and physical footprint.
