I have a York Diamond 90 furnace. When I turned it on for the winter, it starts but only runs for a minute and then shuts off but the blower still runs. When I checked the status light it blinks four times which according to the panel indicates "High Aux or Spill Limit Switch Open"

I am handy but don't have much experience with this furnace. Can anyone help?

Thanks!

There is a wiring diagram and legend on the inside of the blower. Track down the problem device and test or replace.

Follow the wiring diagram that is located on the back sie of the blower door.
