b) CRMR60(-W), CRMR72(-W)
4) Startup–EvapFM energizes. Diagnosis: Check that EvapFM energizes. If not, check
voltage on EvapFM. Check EvapFM windings. Check fan blades for binding.
5) Cool Down–Temperature above setpoint. CTh closed. EvapFM continues. Comp and
ConFM energize. Diagnosis: Check that EvapFM continues. Check that Comp and
ConFM energize. If not, conrm that temperature is above setpoint and CTh is closed.
Check both terminals of CTh (BK) to a neutral (W) for 115VAC. If 115VAC is present on
one terminal and not the other, replace CTh. If 115VAC is present on both terminals,
check Comp, ConFM, and EvapFM.
Check voltage at Comp, external protector, and Comp terminals. Check Comp windings.
Check voltage on ConFM and EvapFM. Check ConFM and EvapFM windings. Check
fan blades for binding.
If Comp, ConFM, and EvapFM are energized and the cabinet temperature does not
cool down, check for a restriction in the refrigeration circuit, low refrigerant charge, or
inefficient Comp.
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.
2. Refrigerator: Prep Table
1) Unplug the appliance from the electrical outlet.
2) Remove the rear panel.
3) Plug the appliance back into the electrical outlet.
4) Startup–EvapFM energizes. Diagnosis: Check that EvapFM energizes. If not, check
voltage on EvapFM. Check EvapFM windings. Check fan blades for binding.
5) Cool Down–Temperature above setpoint. CTh closed. EvapFM continues. Comp and
ConFM energize. Diagnosis: Check that EvapFM continues. Check that Comp and
ConFM energize. If not, conrm that the appliance is not in a defrost cycle, 8-hr. DT is
operating properly, temperature is above setpoint, and CTh is closed. Check voltage on
8-hr. DT. In cooling, 115VAC is present on both DT terminal #1 (BK) and DT terminal
#4(BK) to a neutral (W). If 115VAC is present on terminal #2 (R) to a neutral (W),
advance DT out of defrost cycle or replace DT. Check both terminals of CTh (BK) to a
neutral (W) for 115VAC. If 115VAC is present on one terminal and not the other, replace
CTh. If 115VAC is present on both terminals, check Comp, ConFM, and EvapFM. For
CRMR60 and CRMR72 prep table, also see "HPS Activation (CRMR60 and CRMR72
Prep Table)" below.
Check voltage at Comp, external protector, and Comp terminals. Check Comp windings.
Check voltage on ConFM and EvapFM. Check ConFM and EvapFM windings. Check
fan blades for binding.
If Comp, ConFM, and EvapFM are energized and the cabinet temperature does not
cool down, check for a restriction in the refrigeration circuit, low refrigerant charge, or
inefficient Comp.
