B. REFRIGERATOR TEMP

※ CAUTION

It is appeared the S/W cross spot of ROTARY

S/Wcircuit ①~⑩.

Temp. control is changed KNOB of contructed ROTARY S/W in the refrigerator and it is possible the temp. control 1 step to 8 step.

Temp. control SETTING become partial pressure for R502 resistance and ROTARY S/W resistance.(Row composition resistance of resistance charge to R908 and ROTARY S/W direction). And partical pressure is delivered to MICOM through R505 resistance and recognited temp. control and it become SETTING to temp. control. Voltage or resistance charge of MAINPCB MICOM input for SUBPCB Assy’s ROTARY S/W cross spot direction is same the below.(When measure the resistance charge, connector of MAINPCB CN30is separated and measure the connector terminal.
