Safety First - I unplugged the power source. I removed the console by simply removing several screws. However because the nut fastening the resistor was in a really tight spot and I had little room to work, I decided to remove several screws from the back of the console to open it up. (This step is not necessary - but for me, it just made the job go quicker). I was then able to use my ratchet/socket set to remove the nut from the resistor. I then attached the wires from the timer to the new in-line resistor. I closed up the console, re-attached it to the dryer and DONE!!! The dryer works fine!!! By the way, the set is 25 years old. I initially thought it was the timer itself but after explaining the problem to Rebecca at this iste , she quickly identified the problem as the timer power resistor. Many thanks Rebecca??
The dryer would dry the clothes fine and run through heat cycles and cool down. The timer would also run down, it just would stop even thought the heat stopped. To repair, I took the back off the timer portion of the dryer. At first I panicked. I did not see any part that looked like the new one I just ordered. I searched the internet and found that the original part looked like a black plastic loop with a black and orange wire connected to it. The part I got was the new design. Then I couldn't figure out if it mattered which end I hooked to the black wire. Another internet search showed it doesn't matter which way current flows through a resistor, so it didn't matter. Hooking in the new part was very easy. The time it took to get the information to identify the part, and determine if it matter which end to hook up to which wire took the longest. I would recommend PartSelect put a picture of the old style right beside the picture of the new style. Also would like them to make clear it doesn't matter which direction the Timer Power Resistor went in.
After doing research on the problem I narrowed it down to a resistor issue. The timer will not advance on auto dry but will advance when on timed dry but will not completely cut off. I ordered the resistor. I also located the faulty resistor next to the start button. It was easy! I just unplugged the two clips from the bad resistor and connected them to the new resistor and problem solved!
