8-10
Symptom: Compressor oil pressure low (check gages)
See Section 7, for compressor oil pressure requirements.
Possible Cause
Possible Remedy
Oil diluted with refrigerant
Oil will be very foamy. Check liquid feed
control for overfeed problem.
Oil pressure regulating valve out of adjustment Adjust valve to increase oil pressure. Turn
stem in to increase, out to decrease.
Compressor rotation incorrect
Check rotation direction by arrow indication.
Reverse rotation, if necessary.
Restriction strainer, oil filter, pick-up tube or
oil passage
Clean strainer or restriction in passage or
replace filter.
Compressor thrust bearing installed upside
down
The Mycom compressor thrust bearing on the
shaft seal end has an oil passage hole which
has to be in the proper position when installing
the thrust bearing. Hole up for “WA” and
“WB” series Mycom compressor. Refer to
your compressor manual.
Symptom: Compressor loosing oil excessively
Possible Cause
Possible Remedy
Non-effective oil separator or float
The oil separator will normally return a good
portion of oil leaving the compressor, if it is
working properly. Check the oil float and
return line to see it is not restricted.
Liquid refrigerant in crankcase
Check liquid feed to make sure it is not
overfeeding and that the solenoid valve #20 is
not leaking through when the machine is
stopped.
Compressor piston rings seized or broken
Check compressor efficiency. If rings are
seized or broken, replace defective parts.
Leaking shaft seal
A few drops per minute is okay. If ammonia is
leaking, replace the seal.
