I recently replaced the thermostat in my lg washer dryer combo (WM3431HS). When the drying cycle is running, the time left indicator acts normal for the first few minutes displaying something like 2:48 left to go, but after a few minutes have elapsed the timer will jump down to 4 minutes left to go. After the 4 minutes and machine shuts down, the clothes are not dry. (Normal drying cycle is betyween 2 - 3 hours) Did I need to reset something after installing the new thermostat? Thanks for any suggestions. Mike.
