    York Diamond 80 blowing cold air...
    Like the title says it's blowing cold air. However the small troubleshooting sticker on the inside of the lower panel gives a list of possible problems IF the LED is blinking. Mine is not blinking (or illuminated for that matter). Also the unit constantly runs and the only way to shut it off is by unplugging the unit. Usually this is remedied by the thermostat but it doesn't do anything when turned to off. My initial thought is the thermostat. Suggestions? Thanks for all help.
