Blower won't stop
Posted 08 August 2006 - 11:16 AM
we're awakened to a clicking buzzing noise that's coming from the
air handler under the house. Eventually, it comes on but then, it will
cycle on and off with more clicking and buzzing. After a few mornings of that and cleaning now the fan will not shut off. I thought it would be the fan
relay but I replaced that today and it still runs. Tried removing the G wire from thermostat, waited 5 min - still runs. Does this unit have a sequencer and/or circuit board. What do you think the problem is and what's my next step?

At first it sounded like a bad relay clicking,then you said you replaced it and now it runs all the time.you could of connected the wires to the wrong contacts.there are a set of normally closed contacts and a set of normally open contacts on the relay.If you connected to the normally closed set then it will not stop running.If this is not the case,you could still be getting electicity from your transformer.Look at your wiring diagram.

Like I said, you need to look at your wiring diagram to see how it is wired.You trans former could be fine.Your transformer receives a certain amount of electricity(say 220 V) and it steps this down to let's say (24 Volts)If it's doing what it's suppose to be doing then it is fine.
