What is the first step in an operational test after ensuring proper power?

The first step in an operational test after ensuring proper power is to conduct amperage checks on motors. This step is crucial because it allows the technician to verify that the motors are operating within their specified amperage ranges. Monitoring the amperage helps to identify any potential issues such as motor overload, which can lead to premature failure or burnout.

By checking the amperage first, the technician can ensure that the system is operating efficiently and safely before proceeding to further tests. This initial check can often indicate whether any immediate adjustments or repairs are needed before evaluating other parameters like refrigerant levels, pressure readings, or temperature measurements, which might not be accurate or reliable if the motors are not functioning correctly.

This order of operations is essential for effective troubleshooting and ensures that any underlying issues are addressed first, promoting a more efficient evaluation of the HVAC/R system.
