ClimateMaster 13B0015N04 Pressure Switch

The ClimateMaster 13B0015N04 Pressure Switch is a mission-critical OEM replacement part designed for high-side refrigerant monitoring in geothermal and water-source heat pump systems. Engineered as a high pressure switch, this component serves as a hard-wired safety interlock that prevents terminal compressor failure by interrupting the control circuit when internal head pressures exceed safe operating limits. This HVAC pressure sensor is built with high-grade bellows and a corrosion-resistant housing to withstand the rapid cycling and thermal fluctuations typical of ClimateMaster heat pump applications.

For field technicians, the 13B0015N04 provides reliable mechanical pressure control, ensuring the system remains within its design envelope. Its automatic reset or manual lockout integration (depending on the control board configuration) allows for seamless integration with CXM or DXM controller logic. Replacing a fouled or non-responsive refrigerant pressure switch is essential for maintaining UL-listed safety standards and protecting the hermetic seal of the compressor. This ClimateMaster 13B0015N04 is calibrated for precision, ensuring accurate trip points and long-term durability in demanding commercial and residential environments.

• OEM Compatibility: Precision-matched for ClimateMaster geothermal units, ensuring exact electrical and mechanical fit.
• System Protection: Effectively mitigates risks of liquid slugging or overheating by terminating 24V signals upon high-pressure detection.
• Industrial Build Quality: Features robust internal contacts designed for high-cycle reliability in HVACR refrigeration circuits.
• Fast Response: Low-latency sensing prevents pressure spikes from damaging sensitive internal compressor valves.

• Is this switch compatible with R-410A systems? Yes, this switch is designed to handle the higher operating pressures associated with modern HFC refrigerants.
• Does this require a manual reset? Typically, the 13B0015N04 functions as an auto-reset switch, but modern ClimateMaster boards may trigger a soft or hard lockout after consecutive trips, requiring a reset via the thermostat or power disconnect.
• Where is this switch located? It is typically installed on the liquid line or high-side discharge line near the compressor to monitor peak pressures.
