Troubleshooting, Registers, Condenser Coil

Indoor Blower Motor and Drive - The indoor blower motor fea- tures ball bearings that do not require periodic lubrication. However, if the motor has grease

fittings, periodic lubrication of the motor bearings can extend the life of components but is optional.

If desired, every three years, using a low pressure grease gun, pump grease into the bearing grease fitting until grease just begins to show at the seals. Do not over lubricate. Use any lithium base grease recommended for ball bearing ser- vice.

Damage can occur if the bearings are overlubricated. Use grease sparingly.

REGISTERS

Supply and return air registers must be open when the unit is in operation. Obstructions must not be allowed to block air- flow in or out of the registers.

CONDENSER COIL

An annual check and cleaning, if necessary, of the outdoor coil should be done. Cleaning should be as often as neces- sary to keep the coil clean. Clean any debris and dirt from the outside coil face with a brush being careful not to damage the fins. If extremely dirty, a hose can be used to wash the coil from the inside out while brushing a soapy solution on the outside.
