What should a technician expect when testing circuit draw on a blower motor?

When testing the circuit draw on a blower motor, a technician should expect that there is typically no current draw when the blower motor is not in operation. This is because, in a properly functioning system, the blower motor will only draw current when it is actively turning on and running.

During the testing phase, if the HVAC system is off or the blower is not engaged, there will be no electrical current flowing through the circuit. This is considered normal behavior for electrical components that are in a standby state. Continuous current draw when the blower is off could indicate a fault or a malfunctioning component, leading to potential damage or inefficiency in the system.

Understanding this behavior helps the technician determine the operational status of the blower motor and diagnose any issues that may arise if the blower fails to operate when expected.
