To be honest , you shouldn’t really be opening the door mid-cycle on a dryer. It can cause the overheat temp limiter to ‘pop’ , causing heating probs.
Can i ask you why you are checking the progress mid-way ? This is an automatic sensor dryer , is it not , and therefore the load shouldn’t need checking once you have selected the drying cycle you require. Just start it and let it do it’s stuff. Its how they work best and most effeciently
If you do interrupt it , it will go back to the beginning of the selected cycle but will automatically adjust the time and heat after a few minutes once it’s checked the state of the drying load in the machine. If , for example , the cycle time goes back to the start time of 1hr50 after an interruption , after a few minutes it may well jump back down to the time and cycle stage that it was before the interruption.
