WARNING

Hazardous Service Procedures!

The maintenance and troubleshooting procedures recommended in this section of the
manual could result in exposure to electrical, mechanical or other potential safety
hazards. Always refer to the safety warnings provided throughout this manual
concerning these procedures. When possible, disconnect all electrical power including
remote disconnect and discharge all energy storing devices such as capacitors before
servicing. Follow proper lockout/tagout procedures to ensure the equipment cannot
be inadvertently energized. When necessary to work with live electrical components,
have a qualified licensed electrician or other individual who has been trained in
handling live electrical components perform these tasks. Failure to follow all of the
recommended safety warnings provided, could result in death or serious injury.
including remote disconnects before servicing. Follow proper lockout/tagout

Table 18. Air handler troubleshooting recommendations

Symptom

Probable Cause

Recommended Action

Bearing is excessively
hot

First start after relubrication (Grease
distribution)

Allow machine to cool down and restart.

Over-lubrication

Clean surface of grease and purge.

Over tensioned belts

Adjust belt tension.

No lubricant

Apply lubricant. Check bearings for damage.

Misaligned bearing

Correct alignment. Check shaft level.

Motor fails to start

Blown fuse or open circuit breaker

Replace fuse or reset circuit breaker.

Overload trip

Check and reset overload.

Improper wiring or connections

Check wiring with diagram supplied on unit.

Improper current supply

Compare actual supply power with motor
nameplate recommendations. Contact power
company for adjustments.

Mechanical failure

Check that motor and drive rotate freely. Check
bearing lubricant.

Motor stalls

Open phase

Check line for an open phase.

Overloaded motor

Reduce load or replace with larger motor.

Low line voltage

Check across AC line. Correct voltage if possible.
