HPS Activation (CRMR60 and CRMR72 Prep Table): Check continuity of HPS.
If open, allow time for system pressure to equalize and HPS to reset. If HPS does
not reset, replace HPS and diagnose reason for HPS activation. Conrm ConFM is
energized and fan blade turns freely. Check that the condenser coil is not clogged or
restricted. Check that there are no restrictions in the refrigeration circuit (drier).
Conrm that the appliance location meets factory requirements:
• This appliance is not intended for outdoor use. Normal operating ambient temperature
should be within 45°F to 86°F (7°C to 30°C).
• The appliance should not be located next to ovens, grills, or other high heat producing
equipment.
6) Cool Down Achieved–Temperature cools to setpoint. CTh opens. EvapFM continues.
Comp and ConFM de-energize. Diagnosis: If cabinet temperature has cooled to
setpoint and Comp and ConFM do not de-energize, check CTh continuity. If CTh
defective, replace CTh.
7) Defrost (Prep Table)–Defrost Initiation: 8-hr DT terminates. EvapFM continues. If CTh
closed, Comp and ConFM de-energize.
Defrost Termination: 20-min. DT terminates. EvapFM continues. If CTh closed, Comp
and ConFM energize.
Diagnosis: Defrost Initiation: Manually advance DT cam to terminate 8-hr. DT. Conrm
Comp and ConFM de-energize or remain de-energized. If not, replace DT.
Defrost Termination: Wait 20-min. (±3 min.) or advance DT cam to terminate 20-min. DT.
If CTh closed, conrm Comp and ConFM energize. If not, check DT voltage terminal
#2(R) to a neutral (W). If 115VAC is present, replace DT.
