Diagnosis – Check that UF/S and LF/S open, WCR de-energizes, and WV energizes. 
If UF/S and/or LF/S do not open, see "IV.D. Float Switch Check and Cleaning." If WV 
does not energize, check WCR terminal #2 (GY wire) to a neutral (W wire) for 115VAC. 
If 115VAC is not present, replace WCR. If 115VAC is present, check for continuity 
through WV solenoid. If open, replace WV. After LF/S opens, check that TDR terminal 
#9 (R wire) has power and GM, FM, CR, and Comp remain energized until UF/S closes 
or FT terminates. If not, check TDR. Check that WCR energizes and WV de-energizes 
when reservoir is full. If not, check WCR, UF/S, and WV. See "IV.D. Float Switch Check 
and Cleaning."

11) 

Shutdown (bin full) – Ice fills storage bin to level of BC. BC opens within 10 seconds 

after ice contact. BCH remains energized. WCR, TDR, GM, FM, CR, and Comp 
de-energize.  
Diagnosis: When the icemaker is running, hold ice in contact with BC bulb. If the 
components fail to de-energize within 10 seconds, check BC. See "IV.C. Bin Control 
Check."

1) Move the power switch to the "ON" position to start the automatic icemaking process.
2) To confirm BC operation, hold ice in contact with BC bulb. If the icemaker does not shut 

down within 10 seconds, BC must be adjusted. For BC thermostat location, see Fig. 1. 
Installations at higher altitude locations are more likely to require adjustment. If BC will 
not shut down the unit even after being adjusted, replace BC.
