Fan will not shut off, but compressor does
hi! there, continous fan motor when unit was shutt off,since supply source was already cut off specially on fan condenser motor,the supply of your motor was came from relay mounted on your circuit board control panel,there a holding coil to hold the connection between your fan and ac source,shut off breaker for ac unit first before diagnosing ac unit, try to check this out the relay is still activated giving ac source when shut off,the contactor on relay holding your ac supply was shorted,try to check the connection the circuit activating condenser fan relay,eliminate the short circuit,using multi tester test rod,use manual diagram for circuit control board to lessen complicated diagnosing,focus on fan relay ac source then isolate checking the short circuit replace defective relay,contact point of relay are not repairable.take necessary precaution on checking to avoid shock,this a hard task i would suggest that certified ac technician w/ full knowledge of instrumentation should do this.thank's for selecting fixya and have a nice day.
