7. 0. Trouble check for the cooling cycle :
Symptom
!The EVAP cools down and warms
again.
! The condenser warms in proportion as the EVAP cools.
!The process continues to repeat.
!The condenser is cold.
!The EVAP is not cold.
!The temperature of the compressor is high.
Cause
Moisture in the refrigerant cause the malfunction.
Foreign substances hamper the cooling cycle.
Suggestions
Replace the refrigerant.
Locate the disturbed section and
make repairs.
!No difference in temperatures between suction pipe and
discharge pipe. |
| The compressor |
! The temperature of the compressor |
| is defective. |
is maintained at room temperature. |
|
|
!The EVAP does not cool down.
Replace
the compressor.
!Frost on the suction pipe.
!The condenser is overheated.
!The refrigeration in the EVAP is not efficient.
!The condenser is cold.
!The compressor surface temperature is high.
!The refrigerator is not easily get cooled.
To much refrigerant.
Refrigerant licks (Slight refrigerant leakage causes partial cooling with
frost on the EVAP)
Replace the refrigerant.
After welding the licked parts, replace the refrigerant.
