Blower was working when I first looked at my new home. Upon purchase the thermostat was turned all the way up and probably had been for about a month. Now the blower does not work. I have reset all breakers to no avail. Have troubleshooted the thermostat but it is not the problem. What else should I be looking at? Thanks in advance.

Hi,

Sequencer and fan relay for heating and fan relay for cooling.


Seq. controls blower for heat, but it runs through relay.


Relay controls it for cooling.


Also look for loose wire connections at those and at the molex connector plugs and/or any wire nutted connections.


Thanks,
Robert
