Blower Motor bad or what?
Asked Sep 13, 2005, 11:12 AM
Howdy, My FURNACE/AC blower motor has quit workng. Checked unit... the squirrel cage fan spins smoothy, no bearing noise or roughness, when turned by hand. When I turn A/C on I hear A/C unit come on but fan doesn't blow. Same when turning on heating unit. Same response in 'AUTO' or 'ON' modes.
I do hear a hum at motor... which goes off after a few seconds. It then tries to come on again in about 60-90 seconds to know avail.
When I spin the fan and turn it 'ON' the fan stops abruptly... same in either direction.
With humming noise on I cannot spin the fan manualy in either direction...
Is this fan, capacitor or relay problem?
