if defective. If 24VAC is present, check for 24VAC at GMPR terminal #2 (P wire)
to a neutral (LBU wire). If 24VAC is not present, check GMPR continuity between
terminals #2 (P wire) and #6 (LBU wire). If open, replace GMPR. Next, check for
24VAC at DV. If 24VAC is present and DV does not energize, check DV solenoid
continuity.
13) Shutdown – Bin lls with ice and activates BC actuator paddle. 150-sec. shutdown
sequence begins. 90 sec. after BC opens, Comp and FM de-energize, AM energizes for
0.6 sec., 60 sec. later, GM de-energizes. Diagnosis: Check that BC actuator paddle is
activated and not sticking. Check BC proximity switch continuity to conrm 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 "IV.C. Control Board Check Procedure."
