Board Level Diagnostics for :
* Thermistor Failure FC/RC
* Potentiometer Failure
1 First Turn Off the Product & disconnect the Plug.
2 Remove the Control Board from Box.
3 Disconnect the 10-Pin connector from Board.
4 For Thermistor Failure FC/RC
* Check resistance on pin no. 8 & 9 of CN2 ( 10 pin connec) for RC Thermistor.
* Check resistance on pin no. 5 & 7 of CN2 ( 10 pin connec) for FC Thermistor.
* IF thermistor is open then the resistance is zero.
* IF thermistor is short then the resistance is above 22 KOhms
* IF resistance lie between 0-22 KOhms the themistor is OK.
5 Potentiometer Failure
* Check resistance on pin no. 1 & 8 of CN2 ( 10 pin connec) for Potentiometer.
* It should lie between 0 to 22 K ohms
