Compressor - LG LFX21960ST Training Manual

REFRIGERATOR

COMPRESSOR

The compressor intakes low temperature and low pressure gas from the
evaporator of the refrigerator and compresses this gas to high-temperature and
high-pressure gas. It then delivers the gas to the condenser.
The compressor includes overload protection. The PTC starter and OLP
(overload protector) are attached to the outside of the compressor. Since the
compressor is manufactured to tolerances of 1 micron and is hermetically sealed
in a dust and moisture-free environment, use extreme caution when repairing it.
Notes for Usage
1. Operate this refrigerator on the rated current, (115 VAC, 60 Hz.) found on
the ID Sticker inside. Be careful not to allow over-voltage and over-current.
This is particularly critical when refrigerators are operated in markets other
than that for which they were manufactured.
2. Do not use an inverter to power this refrigerator. Inverters usually output a
square wave instead of a sine wave, and this destroys the compressor
quickly. The damage is not repairable.
3. If compressor is dropped or handled carelessly, poor operation and noise
may result.
4. Use proper electric components appropriate to the particular compressor
in your product.
5. Keep the compressor dry. If the compressor gets wet (in the rain or a
damp environment) and rust forms in the pin of the hermetically sealed
terminal, poor contact may result. If it rusts through, the refrigerant and oil
will be released under pressure. If the refrigerator is running at the time,
this could cause a fire hazard.
6. When replacing the compressor, be careful that dust, humidity, and
soldering flux don't contaminate the inside of the compressor.
Contamination in the cylinder may cause noise, improper operation, or
lock up.
