13) Shutdown–Bin lls and ice engages BC actuator paddle. 6 to 10-sec. shutdown
sequence begins. Diagnosis: Check that BC actuator paddle is activated and not
sticking. Check BC proximity switch continuity to conrm BC proximity switch is open.
If BC actuator is engaged and BC proximity switch is closed, replace BC proximity
switch. If BC proximity switch is open and Comp, FM, and GM do not de-energize,
replace CB. See "II.C. Control Board Check."
