Hi,
Our York HVAC (7yrs old) does not switch on. Thermostat and blower switch are on but blower won't turn on. Checked the power to the unit and it is ok.
How do I reset / jump start the blower?

Please advise.
Thanks

Try browsing through the hvac section someone already posted this problem...I think

I've been browsing and I find nothing that would help.

Trace the wire back from the blower and see if there is power on the line (input) side of the contactor. Then check for power on the control power wire. If the problem is with the contactor, there will be voltage on both the line side and the control wire, nothing on the load (blower) side.

Some contactors have a button or a center piece that when you push it down, it closes the contacts manually. Not all contactors have this feature and if the contactor has burned out, the blower will still not work. If the control coil has burned out, the blower should come on.

From there, I'm not confident enough to tell you to try anything else.

Hello Beaven:
I have never seen a blower motor with a reset on it but I have had to change a lot of blower motors out. They seem to be short lived in some cases and long lived in others. Check it like Square Eye said and then look into a new motor.

Is the cover in place and fastened when you are checking this?
Is that what you mean by the blower switch?
When you remove the cover plate look at the switch itself. Could be broken.

yes the cover switch(the interlock) is in place and tests fine.. We still have to test as suggested by Square guy and then I'll let you know. Thanks.

Hey Beaven! I just had another thought (they sneak up on me sometimes); see if your blower will turn easily by hand. If it won't the motor is definitely burned out.

Hi All,
We could not figure this out.. and had to call the york representative. He figure out the problem in 10 seconds. The problem was that there was an additional inline fuse which we were not aware of that had blown.... because the mice were chewing up the wires from the unit on the outside....
Thanks for all your prompt ideas and repllies!
