Hi According the the York installation instructions these are the diagnostic LED blink codes for the control PC board: OFF - normal operation ON - board failure 1 flash - ignition attempts or recycles 2 flashes - compressor low pressure switch open 3 flashes - compressor high pressure switch open 4 flashes - flue inducer cetrifugal switch open (fault) or closed (fault) 5 flashes - flame rollout switch open 6 flashes - furnace high limit switch open 7 flashes - (optional) heating mode 1 hour waiting period for auto reset from flame failure lockout
When the unit gets into this blowing only cold state, the LED is blinking 8 flashes. There is no 8 flashes on the list.
if thats the case.Then again, sometimes after reseting the unit with the fuse block it will start to work properly for another 4 - 6 - 10 hours. Sometimes a day or so.
The circuit board is a Robertshaw 100-825-04 which a Google search says is now obsolete so I can't find any documentation on it. Also it appears that Robertshaw is not even in the HVAC control board business any more.

Hi!
You can find the codes usually on the back of the blower access door OR the burner service door.
Thanks

Try calling them. Its quite difficult to get the b codes for this.
That board is no longe made. Getting the codes is a daunting task!
Try calling York in Pa. they must have a technical department that can assist you. 1-800-910-YORK
Certainly have the model and serial number when you call... or try their website.

Of note York was bought out recently by Johnson Control.

Just curious what is it doing .... and i know it's not bedding... what type of unit is it ?
2 blinks=high head pressure
3 blinks=high discharge temperature(275 degs)
4 blinks=discharge temperature below 90 degs. for 1 hour,
5 blinks=defrost fault,
7 blinks=outdoor sensor bad(open or shorted),
8 blinks=liquid line sensor bad(open or shorted),
9 blinks= bonnet sensor failure(dual fuel system),
