COMPRESSOR
But if at the initial start of COMP, the high-pressure pipe gets too hot within 3 min. to touch, it means Comp is good.

If this is the case (not bad compression), find the leakage point (weld point)of the gas and weld it, evacuate it and
re-inject gas.
2) Bad COMPRESSOR start-up
● COMP starts up but stops within 3min. (refrigeration cycle blockage)

Trace the blocked points with weld material, thoroughly perform overhaul, evacuate it and re-inject gas.
● Check power supply part (electronic PCB connection part), re-insert it and solidly fix it.
● Check contact point states of the electronic units (PCB-side COMP relay, condenser).
● Check the resistance of the Comp terminal, if you want to see the COMP motor state.
7-10-2. Actions & Precautions per Symptom
1) If although there is no problem with the temperature control part, the Freezer and the Fridge are
not cooled, it is likely due to gas leakage or bad Comp compression.
 When COMP runs continuously for 2 hr. or more or freezing/fridge state is bad, check if there is gas leak at various pipes.
If there is no leak, replace the Comp, thinking it is due to a bad Comp compression.
