Problem Possible causes Possible corrective actions
Compressor oil
level too high or
too low.
Low oil level. Adjust the water flow required for the equipment.
Insufficient water flow - level too high. Check or replace (if necessary) the valve and adjust the proper
superheat.
Solenoid valve return oil not open. Check circuit and possible problem of solenoid valve not opening,
if necessary replace.
Short cycling. Check pressure drop or temperature for diagnostics.
Excess liquid in crankcase - level too high. Check means of regulating condenser temperature.
Level too high with compressor operation. If the system has excess oil, recover and adjust by observing the
sight glass on the compressor.
Operation or selection of expansion value. Correct power supply.
Compressor mechanical problems. Check electrical circuit for possible problem. Then replace
compressor.
Incorrect oil for application. Check all connections and tighten, if necessary replace contactors.
Oil collapse in remote piping. See corrective steps for high discharge pressure.
Loose fitting in oil line Correct to bring conditions within allowable limits.
Compressor
staging intervals
too short.
Control band not properly adjusted. Check and correct.
Water temperature sensor failure. Set correct superheat.
Insufficient water flow. Check for possible problem. Then replace the compressor.
Rapid temperature or flow changes. Check and stabilize load or correct control settings for the
application.
Oversized equipment. Evaluate equipment selection.
Light loads. Checking and adjusting the load.
Equipment will
not run.
Inadequate voltage. Check voltage and correct it.
Reset switch is off. Power up.
No water flow in the system. Flush the system.
Water flow is reversed. Check water direction.
Unit runs, but
does not cool
sufficiently.
Set temperature value is an incorrect
setting.
Set values.
Check data sheet and check system for leaks.
High condensing temperature. Check condenser and repair.
Equipment does not have sufficient water
flow.
Check technical data, check filter in water line and adjust flow if
necessary.
The fan does not
work.
No supply voltage. Check electrical circuit (line down).
Motor defective. Contact the manufacturer.
Motor thermal protection switch open. Check operating conditions, if necessary contact the manufacturer.
