Sure, I will remove the resistor wire from R as well.
Just to recap our goal here. The original problem was that in timed mode (heavy cycle), the dryer will start from a set time (say 60 mins) and move down to about 20 mins and stuck there, leaving the dryer on forever without human intervention. This change will fix it so that the dial will move from 60 to 0 as expected and stop the dryer at the end, right?
Sorry I sounded repetitive about these questions because I really don't know what I am doing with these wiring on high voltage circuits.
I am not clear on your last question. I only found the timer dial has 3 sections, heavy, medium and light. But they are all timed. I don't see an auto cycle or how to use it :-). Maybe I have been stupid for all these years :-).
Thanks again!

Oh, I just looked at the dial setting again. The medium cycle is actually the auto cycle, right? We have never use it, LOL.
So this change will stop the medium (auto cycle) from working properly and allow the heavy cycle to work (and complete it), right? What would happen if someone accidentally uses the auto cycle with this change?
Thanks!

Show me a photo of the front of your control panel detailing the timer. This may fix the problem but not if it is being caused by a mechanical problem within the timer. The timer motor drives a drum inside the timer that has multiple cams on it that operate multiple sets of contacts to operate the dryer in a specific sequence of operations. There is a reduction gear assembly within the timer motor which could be causing the problem. Do you have a multimeter? If so, check the resistance of the jumper resistor. It should read about 4400 ohms.

Here is a picture of the dial surrounding. I used a multi-meter to measure the resistor cable. It measured 4.38 X 2000K. I am not completely sure about the setting 2000K printed on the device. Does it mean 1000K or 2000K? From your suggested value, it seems it should be 4.38 * 1000. Sorry, the setting is 20K X 4.38. Seems much larger than you mentioned. blueking attached the following image(s):

2000K means that is the highest reading for that scale. Your reading of 4.38k is good. Dryer will still function in auto dry, it will tumble and heat but timer will not work like it's supposed to. In auto dry, the timer only starts advancing after the clothes start to become dry. With the way it is connected now, it will advance all the time just as in timed dry.

I am not sure the 4.38 reading means 4.38k. Hopefully it is. So I am all set to put the timer back with the change? Nothing bad will happen, right? :)

The reading is correct but we are leaving the resistor out anyway. Nothing bad will happen. What is the model number of your multimeter?

Here is a link for the multi-meter. The DT830B pocket-size digital multimeterI thought the reading 4.38 needs to multiply the dial selection (which is 20K). Anyway, I trust your judgement since you know so much in this area :-). I have put back the control panel and plugged in the power cord. I will post back once I have it tested with power. Thanks!

The 20k means it will read up to 20kohms in that range setting. If you needed to measure something over 20kohms and under 200kohms, you would move up to the 200k range.

It did not explode or cause a fire :). It still heats. I will need some clothes to run a complete timed cycle to see if the timer will go to the end and stop. Wife had done all clothes for now. I will definitely post back the final result.
No matter what happens, thank you so much for your time and patience to help me out. Hope you have a great week!
