, posted Mon 14 Jul 14:49  
I have a York 3 ton Heat pump currently operating in Cooling mode. The unit appears to be working well in that I am getting about 20 degrees of cooling in air crossing the evaporator coil. The unit seem to cool the house properly as long as it continues to operate.
However, the unit occasionally shuts itself down and the Red LED on the Thermostat displays a pattern of three rapid blinks repeated over and over.
If I power the unit off, the blink code clears and unit performs normally (possibly for a couple days) until the pattern repeats itself.
I have found that the blink code translates to the following:
"Discharge Temperature reaches approx 275 degrees F".
Can anyone advise exactly what this fault indicates and what type of repair is required? Is the system possibly either low or high in refrigerant charge?
I appreciate any and all information on this issue.
Thanks,
Jim

high pressure cut out,clean your condenser coil and see if that helps.could be several different things causing high pressure.

Hi Mississippi,
Thanks for responding. I'll try cleaning the coil.
Airflow on the external unit seems OK but I'll give it a try.
Any other suggestions?
Thanks again,
Jim
