I have York heat pump. It is not cooling. The emergency light is blinking and outside untit not running at all.
I can not get someone to come down until Monday.What can
I do, myself ? Any Idea ?
Two blinks in sequence-then stops-then
another two blinks. I cheked again. The
compressor is working-emittting heat.
But which is not stuck, but not running.
Can it be fan motor ?
The 2 fault code indicates high compressor discharge pressure (> 400 PSI). Most common reasons are: outside condenser unit fan not running, outside coils have restricted airflow, excess moisture in the system or possibly a defective reversing valve.
If the outside fan IS running, see if there is good airflow over the coils. If the fan is NOT running, it is either the fan motor, fan start capacitor or possibly the defrost relay which are at fault.
If the fan is running and the coils are not clogged, you will need to try to get a service tech out over the weekend (if you don't want to wait till Monday).
