COMPONET TEST PROCEDURE RESULT
Switches (with wire leads removed). All of the switches
are measured in the same manner.
Fan Motor (with leads disconnected)
Blower Motor (with leads disconnected)
Stirrer Motor (with leads disconnected)
Turn Table Motor (with leads disconnected)
N. O. and C Terminals
Set the ohmmeter to the R X 1
scale, and measure the resistance
between the normally-open (N.O.)
and the common (C) terminals of the
switch.
N. O. and C Terminals
Set the ohmmeter to the R X 1
scale, and measure the resistance
between the normally-close (N.C.)
and the common (C) terminals of the
switch.
Set the ohmmeter to the R x 1 scale,
and measure across the terminals.
Set the ohmmeter to the R x 1 scale,
and measure the:
a) High speed windings
(blue and black wires)
b) Low speed windings
(blue and white wires)
Set the ohmmeter to the R x 1000
scale, and measure the resistance
between the motor terminals.
Set the ohmmeter to the R x 1000
Scale, and measure the resistance
between the motor terminals.
a) Normal - The meter
indicates infinity.
b) Abnormal - The
meter indicates zero
ohms (a short).
a) Abnormal - The
meter indicates
infinity.
b) Normal - The meter
indicates zero ohms
(a short).
a) Fan Motor - Normal
= 30 to 50 ohms
a) Normal - High speed
: 25 to 45 ohms
b) Normal - Low speed
: 45 to 65 ohms
a) Normal - 3k to 4k
ohms
b) Abnormal - infinite or
zero ohms
a) Normal - 3k to 4k
ohms
b) Abnormal - infinite or
zero ohms
