Ii Control relay is faulty Analysis of Trouble

temperature sensor. Try to turn the adjusting stem of this value in the direction of the lower temperature graduation, and then check the contacts to see whether they are closed. If they are still not closed, dismantle the temperature-sensing disc and then immerse it into warm water to see whether the contacts actuate. If not, it can be preliminarily determined that temperature-sensing agent has leaked out, and it must be replaced with a new thermostat.

d)Problems of motor and other electrical faults

i)Motor windings are damaged or there is a short circuited between turns

Analysis of Trouble

When motor windings are damaged or there the occurrence of a short circuit between turns, the fuse will be blown repeatedly, and the blowout particularly occurs at that instance where you close the knife switch.

Remedy

Check the terminals and the outer casing to see whether they are short-circuited, and measure the resistance of each phase with an avometer. If short circuit occurs or the resistance of a particular phase is low, this means that there is no short circuit in the windings and/or between turns, and that insulation layers are damaged or deteriorated. Another instrument that can also be used in this inspection is a megameter. If the insulation resistance is lower than 2 MΩ, this means that the insulation layer has a breakdown already. If the motor is damaged, repair or replaced it with a new one.

ii)Control relay is faulty

Analysis of Trouble

Overheating, burns or wearing of control relay contacts will generally occur if this is true. All these will cause poor contact in electricity.

Remedy

Dismantle it for repairs, or replace it with a new one.

iii)Poor electric contractor in thermostat

Analysis of Trouble

Damaged contractor and leakage of temperature sensing agent will generally occur if this is true.

Remedy

Replace the old one with a new one.

iv)Check the terminals for loose connection and electric circuits for other abnormal phenomena.

e)Mechanical faults of compressor

i)Seizure of shaft
