MALFUNCTIONING
POSSIBLE CAUSE
CONTROL
POSSIBLE SOLUTION
Warning from the low
pressure regulator of
the refrigerant circuit
Low level/charge of the
refrigerant gas
Check of the pressure
gauge
Fill up of the refrigerant
gas
Block of the thermostatic
expansion valve
Of the thermostatic valve
appears with frost
Substitution of the
blocked valve
No thermal exchange on
the heat coil, air side
Check the fan of the flow
Check of the electrical
absorption, air flow and
tightness and rotation of
the belt
Warning from the high
pressure regulator of
the refrigerant circuit
Refrigerant Gas load
exceeding the request
Verify the pressure gauge
Reduce the gas load
Obstruction of the
condensing coil
Check of the flaps surfaces
of the coil
Clean the surface of the
coil with compressed air
Reduction of the fans on
the refrigerant side
Check the proper working
of the fans and of the
round regulator (if present)
Reactivation of the
normal working speed
