Hi, I'm having trouble with the dryer on my LGWM3431H washer/dryer combo. The machine has been shutting down before the drying cycle is complete, going into cool down (cd) mode even after there should be about three hours left in the drying cycle. The only way I can get the dryer to run continuously is to set it on timed mode instead of normal/more, etc. I suspect it has something to do with the drying sensor. Help! What can I do to fix this?

Just *lost* an entire / detailed post to the wonders of Internet Explorer...

Well here goes again....abbreviated version.

************************************

This is a combo washer & dryer.

This unit uses a DUAL THERMISTOR arrangement.  One THERMISTOR is positioned *before* and another *after* the HEATING ELEMENT.

In the TIMED dry mode---the DUAL THERMISTORS are *disabled* and not used.

This is basically a "Wide-Open-Throttle" setting in which the temperature is at maximum setting. Not good for most fabrics.

In NORMAL mode---both DUAL THERMISTORS are "enabled" and temperature data is actively sent to the MAIN BOARD.

The DUAL THERMISTORS *rarely* fail.

If the *dry cycle* is terminating too soon and no error message (other than "cd") is displayed---this would indicate that the temperature is becoming too hot too soon. This is usually caused by heavy lint accumualtion in the DUCT SYSTEM.

To access the DUCT SYSTEM----the top covers must be removed to inspect / clean the BLOWER MOTOR HOUSING.

The rear access panel must be removed to inspect / clean the DUCT at the bottom of the tub assembly.
