Troubleshooting Information
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit and
discharge capacitor through a 10,000 ohm resistor before attempting to service, unless test procedures require
power to be connected. Ensure all earth wires are connected before certifying unit as repaired and/or
operational.
Symptom
Fan motor noisy.
Compressor does not run,
fan motor operates normally.
!
WARNING
Possible Causes
Outside coil fan blade or inside
coil blower wheel loose or improperly aligned.
Worn fan motor bearings.
Fan motor mounting hardware/bracket
loose or grommets worn (if applicable).
Supply voltage out of specification.
Wire(s) disconnected or loose.
Temperature control faulty.
Compressor motor capacitor faulty.
Compressor faulty.
Overload protector open.

Corrective Action
Check fan blade/blower wheel
for proper position. Reposition
if necessary.
Ensure hardware attaching fan
blade/blower wheel to motor
shaft is tight. Tighten if loose,
replace if stripped.
Check bearings for wear/low
lubricant. Replace motor if
either condition found.
Check mounting bolts/bracket
for tightness. Tighten if
necessary.
Inspect grommets for wear.
Replace if necessary.
Check input voltage for proper
levels. Take appropriate
action if voltage levels out of
specification.
Ensure all connections are
tight and secure. Correct as
required.
Ensure all control connections
are tight and secure.
Check control for proper
operation. Replace if faulty.
Check capacitor for open/
short. Replace if faulty.
NOTE: Discharge capacitor
before testing.
Check compressor motor
windings for open shorts.
Perform compressor direct
wiring test. NOTE: Discharge
capacitor before testing.
Replace compressor if
faulty.
Check protector for continuity.
If open, replace.
NOTE: Ensure compressor/
overload are below trip
temperature before testing.
