TEST PROCEDURE

RESULT

COMPONENT

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.

Switches (with wire leads re-
moved). All of the switches are
measured in the same manner.

Temperature Probe

a) Fan Motor - Normal = 130

to 155 ohms.

Set the ohmmeter to the

R x 1

scale, and measure across the
terminals.

a) Normal - The meter indi-

cates infinity.

b) Abnormal - The meter

indicates zero ohms (a
short).

N.C. and C Terminals

Set the ohmmeter to the

R x 1

scale, and measure the resistance
b e t w e e n t h e n o r m a l l y - c l o s e d
(N.C.) and the common (C) termi-
nals of the switch.

b) Abnormal - The meter

indicates infinity.

a) Normal - The meter indi-

cates continuity, or zero
ohms.

Fan Motor (with leads discon-
nected).

Blower Motor (with leads dis-
connected)

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).

a) Normal - High speed: 25

to 45 ohms.

b) Normal - Low speed: 45

to 65 ohms.

C.

N.C. CONTACTS

N.O. CONTACTS

Set the ohmmeter to the

R x 1

scale, and measure the resistance
between the motor terminals.

Stirrer & Turntable Motors (with
leads disconnected)

a) Normal - 1 to 4 ohms.

b) Abnormal - Infinite or

zero ohms.

Set the ohmmeter to the

R x 10 k

scale, and measure the tempera-
ture probe with the leads posi-
tioned at either terminal.
