Acq158xpo whirlpool window ac power on unit humms but does not do anything else just keeps humming?
Hello there!
well,humming that's the motor stuck up,it can't start up,the running winding of motor has built up current because it can't move on,the start winding is not wotking,check starting capacitor ,using multi tester have set to RX100 test rod on both terminal pointer will deflect to "o"reading,then reverse the test rod on terminal of capacitor this will deflect also to "0" but gradually go back to original position at high value.if this happen your capacitor is good.but if not deflect.defective capacitor,replace defective capacitor,
if capacitor is good,check relay coil,or check motor starting winding resistance,if you get high resistance more than 100 ohms
you motor is defective replace motor,
have a nice day,don't forget to rate me,thank's a lot
