Maintenance Service and Trouble Shooting
1. No cooling
No cooling
If compressor
can run after it stop to
run five minutes and
give power.
NO
Check and repair according to
the section of "the compessor
doesn't work".
YES
If compressor
can run naturally and
temperature raising
of condenser is
very low
YES
NO
Refrigerant
leak,check and
repair charge
refrigerant again.
Block by ice or dirty
things,change filter and change
refrigerant again.
!
When charging refrigerant,we must
notice to make refrigerant true.
