Malfunction Conditions Causes Solution
The internal fan fails. Call an a/c company or electronics expert
to change the internal fan.
The external and internal
fans work, but the com-
pressor does not work.
The compressor’s amperometric
protector has failed (external to
the compressor, where present).
Call an expert to change the amperomet-
ric protector.
The relay for the compressor to
start has failed.
Call an expert to change the relay to start
the compressor.
The capacitor for the compres-
sor to start has failed.
Call an expert to change the capacitor to
start the compressor.
The compressor has a motor
electrical failure.
Call an a/c or refrigerant company to x
the compressor.
The high-pressure safety switch
has failed.
Call an a/c or refrigerant company to x
the high-pressure safety switch.
The compressor contactor has
failed (where present).
Call an expert to change the contactor.
The cabinet does
not get cool
enough.
The external/internal
fans and the compressor
are working.
The cooling unit is insuciently
sized to remove the heat inside
the cabinet.
Exchange the cooling unit with another of
greater capacity.
The internal fan works,
but the external fan
and compressor work
irregularly.
The antifreeze thermostat has
been triggered (where present).
Clean the evaporator coil. Check and clear
any obstacles that hinder airow inside
the enclosure to the cooling unit.
There is insucient refrigerant
in the cooling unit.
Call an a/c or refrigerant company to
recharge the cooling unit.
The thermostat is set incor-
rectly.
Ensure the thermostat is set to the correct
temperature.
The external and internal
fans works, but the com-
pressor works irregularly.
The high-pressure safety switch
or thermal protector inside
the compressor is triggered
because:
• the ambient temperature
exceeds the maximum
working limit.
• the condenser is either dirty
or clogged.
• Ventilate the area where the Micro Data
Center is installed to lower the ambient
temperature.
• Clean the condenser with compressed
air and call an a/c or refrigerant
company.
Too much
condensation is
forming.
The cabinet door is
closed.
The connecting seal between
the cabinet and the cooling
unit has deteriorated.
Check the seals and x if necessary.
