Description
The Carrier 13B0055N02 is an OEM Loss of Charge Switch designed to protect your air conditioning or heat pump system from operating under low or lost refrigerant charge conditions. By monitoring refrigerant pressure and shutting down the system when a loss of charge is detected, this switch helps prevent costly compressor damage and extends the service life of the equipment.
Key Features
- OEM Carrier replacement part — engineered for precise fit and function
- Monitors refrigerant circuit pressure to detect loss-of-charge conditions
- Shuts down system operation to protect the compressor from damage caused by low refrigerant
- Direct replacement for compatible Carrier residential and light commercial systems

Why Loss of Charge Protection Matters
Operating an air conditioner or heat pump with insufficient refrigerant charge can cause the compressor to overheat, lose lubrication, and fail prematurely. The loss of charge switch acts as a critical safety device — interrupting the control circuit before damage can occur. Replacing a faulty or failed switch with the correct OEM part ensures your system’s safety controls perform as designed.
Application
- Compatible with select Carrier air conditioning and heat pump systems
- Designed as a direct OEM replacement component
