Sorry, we couldn't find any existing installation instruction that matched.
Dryer had no heat and run forever.
after watching many videos on my problem and finding Partselect i read about others with same type issues and i decided to attempt my own repair.the first thing i did was go to home depot and buy a ohm meter around $10 then started testing all switches etc.first unplug the dryer then removed the rear panal and tested all circuits.my heating element tested bad so i removed it following the instructions from partselect taking about 5min.my heating element was broken.its funny but my dryer kept on running continually when it stopped heating,but the timer would move to the very end and just not quit.after reading on partselect i determined that my resistor not my timer was the problem.so i ordered the resistor without testing it first from partselect.turns out it was the problem now my dryer heats up fine and goes off like its supose to.i do advise to test things first like i should have but i just got lucky on the resistor.partselect is the only place i will buy from they are fast getting your part to you 2 days for me,and very cost effective.i spent around $84 including the cost of a ohm meter to repair my dryer which is 18 years old.beats the cost of replacing the dryer which i think many will agree.good luck on your repair hope this helped it was my first time ever repairing any home appliance.

Dryer does not turn off. Will stay in the Cool Down cycle
My dryer timer would run through the heat cycle and move in to the cool down cycle. It would not move past the cool down cycle, and would not shut off automatically. I tried replacing the Thermal Fuse first, since I'd already removed the back panel to diagnose the problem. There was no change - the dryer did not shut off automatically. Next, I removed the back cover to the timer console. The Timer Power Resistor looks like a black circle and a rectangle joined together. It was attached to the back of the on/off switch by a single hex head screw, and the resistor has orange and black wires attached. The replacement Power Resistor doesn't look like the resistor that was in my dryer. It is rectangular in shape with 2 male spade connectors. I attached the orange and the black wires to the new power resistor. I started the dryer and it went through a full heat/cool down cycle, and automatically shut off with the end of cycle buzzer sounding. Total part replacement time was about 10 minutes.

Dryer would not shut itself off whether in the timed or auto dry cycles
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??

Dryer would not stop - Would heat and dry but never shut off
Replaced the Thermal Fuse first - 30% chance - didn't help! Then I replaced the resistor - Not an in-kind replacement - looks different-Guessed the wrong place first [no specific directions :( ] and got some sparks - Yikes! Picked the second place and installed the resistor and it work PERFECT. Spent Less than $50 and back in business = GREAT!!

Dryer wouldn't shut off
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.

What is the ohm rating on this resistor. I tested the current resistor i have and the meter shows 4.7 ohms, i am not sure if the resistor is good or bad.
For model number 279872
PartSelect logo
Hello Ron, thank you for your question. The resistance between the two terminals of this Time Power Resistor should measure between 4050 and 4950 ohms if it is functioning okay. We hope this helps.

I am looking for a resistor part number 3388706. The one that comes up here doesnt look anything like the one from my Roper dryer. Mine is black and only has the 2 terminals coming from it. And a hole for the screw to hold it down. The one shown here has wires coming out of it . I am wondering if it is the same thing and why mine doesnt have wires. I dont want to order something that wont work . Thank you amy
For model number REL4622DL0

Voltagethe parts diagram is not very detailed and am not sure which par i need, either the relay or timer resister. The dryer runs but doesn’t heat up, checked continuity through the heater coil but the wire that comes from the heater coil and to the motor and then to the return of the ac is open. Voltage readings were made between ac into the heater and neutral and read 120 vac on both sides of the heater, no return which is supplied by either the relay resistor or the relay. Any help would be appreciated.
For model number 3RMED4905TW0

Hi Douglas, Thank you for your question. If your dryer is not heating correctly, the timer power resistor is just one of the parts that you will need to check. There are some parts that you will need to check to see which one is causing the issue. You will need to check the door switch, the thermal limiter, the terminal and wire kit and the drive belt. I hope this helps. Thank you and have a great day!

I've have a replacement resistor for my Whirlpool dryer that I need to install but can't seem to find where on the dryer it's located. This is in trying to fix the timer not moving in the cycle portion and not shutting off in the minutes portion of timer
For model number LE5770XWW0

My dryer will start but then turn off after a few minutes , it won’t restart for a while then it will start after a while . The problem was intermittent but is now happening more frequently
For model number LTE5243BWO

Hello Paul, Thank you for your inquiry. We would recommend checking the following parts to fix your issue: Dryer Thermal Fuse, Cycling thermostat, High Limit thermostat, Door Latch kit, Drive motor and the timer. You can test the parts with a multi-meter. Hope this helps!

Is there a video that shows how to replace in line resistor? My timer is not advancing. thanks

Hello Randy, Thank you for the question. Very sorry but we do not currently have a video for the resistor. I was able to locate a repair story from a previous customer. "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.

Are both wires on this resistor kit as short as shown? One of them needs to be very long to reach the bottom of the heater.
For model number LER5636EQ3
PartSelect logo
Hi Bob, Thank you for the question.The wires are both as shown. The resistor you listed attaches to two terminals on the dryer timer so you shoudl not need a long wire.Hope this helps!

The resistor on my dryer runs for the back of the timer down to the thermostat at the base. Can i splice in the resistor you sell and make it work.
For model number LER3624EQ0

Hi Damien, Thank you for your question. This resistor is the correct part for your appliance according to your manufacturer. So it should work. I hope that helps. Good luck with your repair.
