Current Sensors
Current sensors monitor the electrical current flowing to HVAC equipment such as blower motors, fans and compressors. These sensors send a readable signal to the control board. Control boards can determine if the electrical flow is correct, ensuring compressors and fans are operating within safe ranges. If electrical flow is too low or too high, the control board can identify problems such as a failing motor or blocked airflow....Read more
If the information that the current sensors send to the control boards is irregular, the system may shut down to avoid system damage, or an alert may be sent to technicians or facility managers for further investigation. Sensors and control boards work together to provide technicians data to help troubleshoot system issues.
This data is also important when planning for scheduled maintenance. Current sensors should be checked for loose wiring or corrosion. A multimeter to measure electrical values is a necessary diagnostic tool used during preventative maintenance or troubleshooting. This tool helps determine if sensors are providing accurate readings. Comparing readings from current sensors with the actual current draw from compressors or motors is important in detecting discrepancies.
