ohm-milliammeter) or DVM (digital-voltmeter) having a
sensivity of 20,000 Ω per volt DC or greater.
n Resistance checks must be made with washer/dryer
unplugged or power disconnected.
n Avoid using large diameter probes when
checking harness connectors as the probes may damage
the connectors upon inseron.
n Check all harnesses and connecons before replacing
components. Look for connectors not fully seated, broken
or loose wires and terminals, pin inseron, or wires not
pressed into connectors far enough to engage metal barbs.
