Motor Test Cord - Maytag 111990" Automatic Dryers Service Manual

Note: Overloads on a circuit breaker
or fuse can be traced to the product
being tested or the circuit breaker (or
fuse) by checking the product's current
draw. If the amperage reading is less
than the breaker reading, the breaker
or fuse box is at fault.
USE OF AMMETER ON DRYER
There are two currents of concern to us
in an electric dryer; the heating
element current and the drive motor
current. These currents can be meas-
ured by use of a "split line cord" exten-
sion for the dryer cord or by attaching
the ammeter to the respective power
line wires at the dryer terminal block.
Current measured should be 21 amps
on the heating element side of the line,
24 amps on the drive motor side of the
line and 4 amps on the center or
neutral line.

MOTOR TEST CORD
The motor test cord may be used. to
electrically check operation of the drive
motor while still installed in the unit.
Testing of the motor in this manner
determines whether or not it will run
independently of other electrical com-
ponents.
Two test leads are required to check
operation of the drive motor. To check
the motor for running, hook up test
cord as shown.
