ConFM Diagnosis:
RFH1-SSB(-HD)(-HS)(-HSE) Refrigerator:
If ConFM does
not energize, check for 115VAC at CB K1 connector pin #10 (GY wire) to a neutral
(W wire). If 115VAC is not present, replace CB. If 115VAC is present, check for
115VAC at Comp relay black (BK wire) and red (R wire) to a neutral (W wire). If
115VAC is not present on the black (BK wire), check wiring connections. If 115VAC
is present on black (BK wire) but not on the red (R wire), Comp relay contacts are
open. Confirm 115VAC on Comp relay coil gray (GY wire) to a neutral (W wire). If
115VAC is present, and contacts are open, replace Comp relay.
d)
EvapFM Diagnosis:
Check that EvapFM is running. If not, check for 115VAC at
CB K1 connector pin #3 (DBU wire) to a neutral (W wire). If 115VAC is not present,
replace CB. If 115VAC is present, check EvapFM blade for binding and EvapFM
continuity.
