28. FAULT ANALYSIS

Syptom

Cause

Solution

The unit does not turn on a) faulty power supply

b) wrong connection of remote keyboard

a) Check protections, fuse, etc.

b) Check connection and polarity

The compressor does

not start up, LED
compressor is on

a) faulty power supply

b) faulty contactor
c) internal klixon is open

d) Compresor full of liquid

a) Check protections, fuse, etc.

b) Replace
c) Wait for recovery and check compressor

intensity

d) Plug in the unit to activate crankase heater

(when included) and wait several hours before
switching on. Load-unload circuit alternatively

The compressor doesn’t

start. Compressor led
flashing

a) faulty power supply

b) faulty contactor
c) internal klixon is open

a) Check pressure value and/or check safety

devices (pressure switches) by checking
continuity in board connectors. Look for the

cause:

LP switch closed: switch on-off the unit

faulty pressure switches: identify and

replace.

b) Wait and/or check AC parameter
c) check electrical continuity in board terminals

The compressor stops

some few seconds after
having started. The

motor produces an
intermittent noise and the

internal klixon is opened.

a) Low supply voltage

b) Faulty starting kit (check the starting relay)
(only single-phase units)

c) Blocked compresor
d) Blocked compresor

e) Liquid slug (the starting up was posibly
done without connecting the crankage heater

with sufficient time

a) Check the power supply and look for the

voltage drop
b) Replace compressor and start kit (only

single-phase unit)
c) Check oil level and oil return to the

compressor through the suction line. If needed
install oil traps or remake the suction line.

d) Replace compressor
e) Plug in the unit to activate crankase heater

(when included) and vacuum for a time.
Reload and start-up the unit

Repetitive compressor
starts and stops

a) if the compressor LED is flashing
b) if the compressor LED is on (opened klixon)

c) Too small regulation differential or too
powerful unit for the room size, or empty room

without any thermal inertia.

a) Check pressures and/or safety chain to look
for the activated device.

HP pressure switch: condenser is blocked,

poor ventilation, too much refrigerant, high

room temperature, faulty control of condensing
temperature, etc.

LP pressure switch: connect the

manometer to HP&LP switches and bypass

refrigerant from high pressure to low pressure
sectors. Then find out the reason (frost, leak,

condensation control, valves, etc
b) V Check oil level and oil return to the

compressor through the suction line. If needed
install oil traps or remake the suction line.

c) Increase regulation differential (parameter
Hy)
