a) Check
condenser control operation |
| b) Suction
shut-of valve partially closed |
b) Open
Valve |

Insufficient refrigerant in system |
c) Check
for leaks. Repair and add charge |
| d) Low
suction pressure |
d) See
Corrective Steps for low suction pressure below |
|
e) compressor-operating
unloaded |
e) See Correction Steps
for failure of Compressor to load up below |
| f)
Condenser too large* |
f) Check
condenser rating table against the operation |
| g) Low
