SOURCE: york diamond 80 heater does not fire up

Mostly likely the problem is in the pressure switch that tells the board that the blower started and it is okay to fire the burner. The pressure switch is usually a 2" or so round thing about 1" thick, it will have one or two tubes coming out of it that go to the blower or heat exchanger. Make sure that the tube is not cracked or that it has not come off at either end.
The pressure switch can be jumped out to check out if that is the problem, but you need to jump it out after the cycle has started and the switch needs to open after a cycle for the heater to refire again, so that fix would be very temporary. But it may tell you for sure what the problem is.

SOURCE: Main blower fan is not starting on my York Diamond

Hi,
Check to see if the blower motor is actually getting power to it...You will have to check for power on the heating speed terminal... and the neutral wires....you should have 120v across those two wires....
If you have power then the motor is bad...if no power then the heating relay went bad on the circuit board and you will have to replace the circuit board...

That is a common problem as those relays are often to light and wear out...

Just realize that without an electrical meter to trace things through you are really just grabbing at possibilities and not really able to correctly diagnose your problem...

SOURCE: Hi, I have a York

a limit open is saying that your furnace is over heating. a few things could be wrong. dirty filters, blocked air return or closed vents. the roll out switch,if your furnace has one , is also in this loop .it normaly will be needed to reset and is on top of the roll out sheild in the burner compartment. call a repair company if this is the problem.

SOURCE: York Diamond 80 Furnace: blows cold air after

There may be more than 1 limit switch. Look at the wiring diagram and follow it to all switches. Or jump out the complete circuit.

Is there a chart on it somewhere that describes what each mode of flashing means? Most of them do. Inside the front cover,,,somewhere on the inside of the panel that covers the filter? I've never seen one of these without that diafram.
