In case the compressor cannot be started, you must find out the origins of this trouble through systematic checkup, because probably there are many causes, including the electrical and mechanical parts.

a)Inspect the power supply to see whether it is connected to the compressor circuit.

Analysis of Trouble

In case the compressor cannot be started, this will generally exhibit in the power supply circuit, for instance, power failure, poor contact of switch, and blown fuse. Make a comprehensive analysis of these phenomena, find out its real cause and take corrective measures to resolve the problem.

Remedy

i)Check the input power circuit to see whether there is voltage in the power supply, note: the circuit that is connected to the knife switch. This can be determined with a voltmeter or a test pencil. If a blown fuse is found, ascertain and remove its cause, then replace it with a new one of the same specifications.

ii)Check the compressor accessories, including its thermal protector and relay. In case the thermal protector is damaged, the compressor cannot be powered on. If the relay is out of order, the motor will not run and hum sound can be heard from it after the compressor is turned on. In that case, shut it down immediately, otherwise, the motor windings will be burned out in case this condition lasts longer.

iii)Check the relay contacts and plugs to see if they are perfect and work reliably. Poor contact may cause the motor not running or humming.

b)Check the circuit voltage to see whether it is normal

Analysis of trouble

If the circuit voltage is obviously lower than its rated value, it will be difficult to start the motor, and a hum sound can be heard from it.

Remedy

Measure the voltage with a voltmeter; if it is really too low, give directions to the user for buying a stabilizer to step up the voltage, thus normal operation can be achieved.

c)Check the thermal relay to see whether its contacts are closed.

Analysis of Trouble

The contacts of thermal relay sometimes may be open due to the leakage of temperature sensing agent from the temperature sensor.

Remedy

Remove the relay cover to check up its contacts. If they are open, this means that the original setting is not properly set or temperature-sensing agent has leaked out of the
