Abstract
A method includes commanding a motor coolant control valve to open at a first time to provide a supply of coolant to a motor coolant flow channel that delivers coolant to a motor of a compressor. A first detection of a coolant return temperature is received at a first time from a temperature sensor connected to a coolant return line that receives coolant from the motor coolant flow channel and returns coolant to another portion of the compressor. A second detection of the coolant return temperature from the temperature sensor is received at a second time after the first time. Based on the first detection and the second detection of the coolant return temperature, it is determined if the motor coolant control valve opened at the first time, and remedial action is taken when the motor coolant control valve is determined not to have opened at the first time.
