Capacitors for Motors and AC compressors

The two types of capacitors in both heating and cooling systems:
Their main purpose is to temporarily store electrical charges.
Run capacitors  run the compressors as well as fan motors. They are also important in increasing torque when one of those systems starts up and help maintain a consistent voltage as the system operates.
Start capacitors are used only in heat pumps and air conditioners to provide the initial power at start up.
 
Capacitors start the entire motor system and keep those motors running while the unit is in use. Without a functioning capacitor the unit will not work/ will short cycle.
Capacitor failures are the most common reason that AC's break down. The heat generated by the capacitor combined with the hot summer weather can cause the capacitor to overheat. It is possible for capacitors to either completely stop working or just lose their operating range, but the results are the same – no air conditioning.

FAQ Blower Motor rotation

FAQ Blower Motor rotation terminology explained (Canada):

CW is clockwise

CCW is counter-clockwise

LE is lead end

SE is shaft end

CWSE is clockwise shaft end

CCWSE is counterclockwise shaft end

CWLE is clockwise lead end

CCWLE is counterclockwise lead end


DS is double shaft = Motor has one rotator exiting both ends, they're both CW and CCW.

 

SHAFT END:

hold your motor up in front of you and point the shaft towards yourself.
If the shaft rotates to the right, your motor is clockwise shaft end CWSE.
If the shaft rotates to the left, your motor is counterclockwise shaft end CCWSE.

 

LEAD END:

hold your motor up and point the shaft away from you.
If the shaft rotates to the right, your motor is clockwise lead end CWLE.
If the shaft rotates to the left, your motor is counter-clockwise lead end CCWLE.

Since shaft and lead end are opposites:
CCWLE = CWSE
CCWSE = CWLE
