Possible causes and solutions
PROBLEM
COMPRESSOR WILL NOT
START
THE TEMPERATURE IS TOO
COLD
© 2004, IMI Cornelius Inc.
POSSIBLE CAUSE
No voltage in the electrical
socket.
The electrical conductor or
wires may be cut.
Defective electrical
components such as:
thermostat, relay, thermal
protector, etc.
Thermostat in "off" position.
Compressor motor has a
winding open or shorted.
Dirty condenser; lack of air
flow.
Low voltage.
Compressor is stuck.
Temperature control contacts
are open.
Time clock circuits are open.
Incorrect wiring.
Thermostat knob is set at a
very cold position.
Thermostat does not
disconnect the condensing unit.
Thermostat capillary bulb is
loose or installed improperly.
Control contacts are stuck
closed.
Defective or incorrect
temperature control.

SOLUTION
Use a voltmeter to check the
voltage.
Use an ohmmeter to check for
continuity.
Replace defective components.
Turn the thermostat's knob to
its maximum position and wait
to see if the compressor starts.
Measure the ohmic resistance
of the main and auxiliary
windings using an ohmmeter.
Compare them with the correct
values.
Clean condenser and allow for
air circulation.
Use a voltage regulator if the
voltage is lower than 103 volts.
Change the compressor.
Repair or replace the contacts.
Determine the reason and
repair or replace.
Check the wiring diagram and
correct.
Set the thermostat knob to a
warmer position and check if
the compressor stops
according to the thermostat's
operating range.
Check the insulation of the
thermostat. If the problem
persists, change the
thermostat.
Correctly fasten the thermostat
capillary bulb.
File contacts. Change the
control. Check amperage load.
Determine correct control and
replace.
