The Current Sensing Compressor Lockout Board is a critical safety and diagnostic component designed for high-performance HVAC systems. This control board monitors the electrical current flowing to the compressor to identify potential faults, such as locked rotors or overcurrent conditions, automatically locking out the system to prevent expensive hardware damage. As an ignition modulating circuit, it ensures precise operation during the startup sequence and maintains system stability. Whether you are troubleshooting an air conditioner that won't stay running or a heat pump experiencing electrical errors, this replacement board is essential for restoring reliable climate control and protecting the longevity of your compressor.
