Indeed, damage to the refrigerator or freezer that kind lot. To determine the damage occurred, we must first know the state of the engine coolant is concerned. After knowing the state of the engine coolant, then performed the examination.
In general disruption in the refrigerator and freezer is caused by leaks in the pipes, too much in filling freon gas, coil surge on the bike, and the deficiencies in charging Freon gas, compressor and leaks. Disturbances that often arise in the case so far.
A. REFRIGERATOR MACHINE DOES NOT WORK
Meanwhile, when plugged in the socket outlet voltage source machine refrigerator does not work at all is a sign of damage to the machine refrigerator. Motor does not sound movement, even so this compressor. If you encounter such damages this, it is necessary to estimate or conjecture to determine the cause. Generally, if the refrigerator does not work even though the cable is connected to the outlet may be caused by the following things.
a. starting on the capacitor is open
b. overload is open
c. open contacts of the relay continues
d. no cable socket dropouts
e. strating open sircuit the wing does not work together
once.
If there is suspected cable channel towards the outlet is lost then the steps that must be done as follows.
a. Check the cable connection in the socket. Usually there is interference in this area with cable disconnection.
b. Checking the entire surface of the cable from the jack to the engine coolant.
c. Also check the channel leading or attached to the dynamo. Perhaps on-tap at her regardless.
If the alleged interference with the overload, usually the voltage to drop even disappeared altogether. Things that need to be done, among others.
a. Check the voltage source.
b. Measure by using a multitester to determine whether the incoming voltage according to the cooling needs of the engine.
c. Finding the location of the electrical current causes the voltage is lowered.
The refrigerator does not work also due to the starting capacitor is open. To see this need to check the capacitors. If it is worn, it must be replaced with a new one. If dropped, quite soldered. Moreover, it may continue to open the relay contacts so that an electric current can not flow. It can lead to a dynamo of energy and still do not get dead. The steps that need to be done as follows.
a. Check the wires on the relay in question.
b. Plates check if it still works.
c. Checking system settings, whether normal.
If the machine or refrigerator not cooling path may also sircuit on startingnya disorder, action should be taken to ensure that the examination of this section conjecture. If there is interference needs to be improved in a way that is adapted to the user settings.
Other disorders on the engine coolant may be noise. If the refrigerator found that create noise should not be allowed. If allowed to drag would negatively affect other units causing new damage. Should be checked. The possibilities of noise on the engine cooling caused by the following things.
• pipe which coincide with the cabinet,
• screws or bolts that are less harsh or detached,
• damage to the fan, and
B. damage to the compressor.
To find the cause of the noise, the first step can be done first inspection of refrigeration piping systems. Perhaps the presence of pipes connected to each other is set to normal, in accordance with the applicable instructions (standard size). If the pipe attached to the cabinet, should be kept away. Checks can be followed by looking at the whole series is installed with bolts or screws. There may be a screw loose or less hard that create noise. If the screws are removed, then plug it back in, If there is a screw that is less tight, it should be ensured that all the mounting bolts and screws quite perfect.
• Observing compression pipeline. Carp good on the compressor, which closes when the thumb is released kompre pipe, there is a burst of (pressure) which can simply fast. This method can also be done on the famil suction pipe or filling (two iron pipes are more than pipe compression). The difference is, when two pips are closed, there is no airflow at all from compression pipeline.
• If the weak gusts of pipeline compression (open-closed pipe compression with the thumb), certain conditions suction valve or compression or both already Rusal * To replace the valve, the compressor should be cut or opened first by using a hacksaw. After the valve is installed, compressor parts reunited with electric welding. Double check and make sure no welding kebocoron the compressor. Next, turn on the compressor and do testing of suction pressure by opening and closing the press or suction pipe. using the thumb. Dismantling the engine compressor is too risky cause compressor leak, body contact, even unusable. In addition, the compression and suction valve replacement compressor does not guarantee long-lasting. Therefore, in order to work optimally sisters, should be replaced with a new compressor.
Other types of damage we often encounter a disturbance in the compressor, which can not be automatic starting and often audible buzzing sound. This damage may be caused by the care and use of the wrong, the current drop in incoming voltage to the motor (dynamo), the starting capacitor is open, the relay contacts are kept open, open sircuit on the starting winding, and coil (spoel) shorted to the body, good compressor pressure exceeds the limit, the compressor is jammed, and damage to the starting capacitor. To overcome this damage, among others, need a thorough examination of the electrical system and related tools such.
RELAY BURNING
If the relay is on fire, then the dynamo and compressor machine was not functioning, or even vice versa work continuously without stop automatically. This is because the relay function to decide the incoming flow automatically when the motor is spinning for a few seconds or minutes. Relaynya burning may be caused by the presence of:
• a low voltage current,
• voltage current that exceeds the limit,
• running capacitor that is not appropriate,
• start cycling,
• relay that continues to vibrate, and
• relays that do not fit with spoel running.
Low voltage will cause the relay to burn. Voltage is less than 10 percent of the needs of the electric dynamo, resulting in the relay armature moves slow and can not be cut off. Relay constantly exposed to currents that ultimately there is a fire in this section. The steps that must be done is as follows.
• Measure voltage current by using a multitester (the voltmeter / AVC).
• Increasing the voltage, if it is less than ten percent.
In contrast, high voltage or current that flows very kuatdan cause excessive burning relay. Excessive current causes a very heavy burden
the relay circuit that finally there was damage. When suspected because of excessive voltage, then the steps that must be done as follows:
• Testing or measurement using a multitester to confirm whether the voltage actually exceeds the limit or not (using AVC).
• If it is true there is a high voltage exceeds the requirements (ratting dynamo) then it should be lowered.
• Replace with new relay.
Relay burning can also be caused due to running capacitor is not suitable and not suitable so how it works is not normal. The steps that must be done is:
• Match running capacitor according to the instructions or guidelines.
• If it does not match the reality should be replaced with a new running capacitor matching.
State that too often lead to start the relay armature be burned. This is because the relay does not hold with such a situation. Try doing the following actions:
• Check the relay if it is appropriate.
• If it does not fit and do not fit should be replaced with a new one.
• Check also the starting capacitor.
Vibrating relay will cause a short circuit and relay burned. The steps that must be done is as follows:
• Before installing the relay should be fitted once the bolts and nut fastener and plate-license plate.
• Tighten or harden first before reinstalling.
• Installation should be confirmed in other settings appropriately and harden the bolts that attach the relay function.
