The blower stopped working and makes a loud buzzing noise when I try to turn it on. Is it the motor or the relay?

Hi,

Would need to test for voltage at motor leads to know which it is. May be something else also.


Turn thermostat or furnace switch to fan ON continuous and see if just the blower motor runs.

IF not, spin blower wheel and see if it starts then.




Thanks,
Robert
