COMPRESSOR NOT
STARTING
POOR
PERFORMANCE OR
OVERHEATING OF
COMPRESSOR
TECHFROST
PROBABLE CAUSE
Compressor protection cutting in
Electrical problems
Component problems
Improper use of the appliance
Fault on the cooling circuit
CHECKS
Closely-spaces starts do not give time for
pressure to re-balance:
Check that the goods are not placed in
the compartment hot or full of water
Check the state of the gaskets and the
number of times the doors are opened
The capillary tube is not operating
properly: check the loading of the circuit in
general and the compressor in particular
Power supply voltage is outside the
admitted range
The compressor terminals are not live;
check the connections and the state of
the contacts upstream from the motor
Compressor has mechanical faults
Winding split or burnt
Type of load: check that the goods are not
placed in the compartment hot or full of
water
Compartment doors: check the state of
the gaskets and the number of times the
doors are opened
Incoming air is insufficient; check the flow
through the cooler condenser
The amount of cooler is no longer
sufficient: check pressure for suction and
delivery and look for leaks on the circuit
Compressor has problems of mechanical
output: check pressure for suction and
delivery
