LUBRICATION
The indoor blower motor and induced
draft motor are prelubricated by the
motor manufacturer and do not require
further attention.
The motors must be cleaned
periodically by a qualified installer,
service agency, or the gas supplier to
prevent the possibility of overheating
due to an accumulation of dust and dirt
on the windings or on the motor
exterior. Air filters should be kept
clean. Dirty filters can restrict airflow
and results in motor overheating.
Reference Figure 22 for proper
removal of the blower assembly on
downflow models.
