3LWED4730FW0 Whirlpool Dryer - Instructions

First I unplugged the dryer, then removed the back panel, this exposed most all of the wiring and I could see the heater coils.
Not knowing what the problem was I started looking at the coils and could not see any broken parts.
So then checked the thermal fuse for continuity I removed the two wires from it with a small pair of needle nose pliers, it was held in place by two screws, once they were removed the fuse came out easily, I checked continuity with a volt meter placing the meter on X1 Ohms and could not get a reading.
I replaced with a new one and put it all back together the way I took it apart.
Then I plugged it in and it worked first time, I now have warm dry clothes.

Removed the two screws that attatch the lent channel to the top of the dryer, then lifted the top of the dryer by pushing in on the two locking tabs located at the front , left and right , corners of the dryer top with a small flat head screw driver. The top of the dryer will fold back out of the way. At this point I removed the two 1/4 inch screws that are located on the inside of the dryer front left and right corners that hold the front panel/door to the two side panels. Now I was able to lift the front panel up and set it to the side. The bottom of the front panel that contains the dryer door that I just removed was held on the bottom by two clips that slide into slots on the front panel and did not require any removal to disconnect the bottom of the front panel, just pull up on the front panel. Since the tub was held in place by floating on a seal at the back of the dryer and a seal on the front panel , which I just removed the tub is now free floating except for the two alignment roller wheels at the bottom of the tub. It is easier if you lay the dryer on its back at this point with front of the tub pointing up. I pulled the tub out and cleaned the years of built up lent and removed all the pieces of the old , destroyed, belt. Note, the belt tentioner is located at the front of the motor which on the bottom right hand side. If your belt is broke like mine the tensioner may/will fall to the back of the dryer when you tilt it back, but do not worry. Once the dryer was cleaned up I put the tub back in place , still on its back and made sure the two alignment rollers were in place and rolled freely when the tub was turned by hand. Another note, my original belt tensioner did not have a rolling wheel that the belt rode on , but was a semi-circle smooth surface that the belt remained in constant friction with when the dyer was running, so I made sure the replacement tensioner I ordered with my new belt did have a rolling wheel that the belt would ride on, which I believe will reduce wear and extend the belt life. The new belt came with a diagram of the belt and tensioner routing which was helpful. Note: do not take the tensioner wheel off/apart when trying to route the belt. Follow the instructions routing diagram. The tensioner is held in palce by inserting the bottom back half into the slot in the bottom floor of the dryer making sure it is aligned with the belt pully on the shaft of the dryer motor. The dryer is still on its back side. Now, it was easier for me to route the belt around the center of the tub, following the marks from the original belt, and hold in in place in a few spots with masking tape and then route it thru the tensioner and onto the front pully of the motor. Make sure you have the grooves of the belt against the tub and the grooves are aligned with the pully on the motor. Now you can remove the masking tape that was holding the belt around the tub and spin the tub by hand watching the belt making sure it is not in a bind and is traveling around the motor pully , tensioner and tub freely. Make sure the tub is still sealed on the back side wall. As you turn the tub by hand you can adjust the belt by hand so that is following the original marks around the tub left by the orignal belt. Also double check the two alingment rollers and make sure they are spinning and on track. Now put the front panel with the door on by sliding it onto the two clips that are one the bottom at each side and put the two screws in that hold the front panel to the two side panels. Now stand the dryer back up and spin the tub by hand again making sure it has a good seal on the back side and on the front panel. Pull the top back down and put the two screws in that hold the lent channle to the top. I am not sure when the belt started failing on my dryer, but was amazed at how quiet it runs now. Guess I was use to the extra noise made by a dryer that was about to die. This was a cheap and easy repair and glad I did it myself.

Cleaning the lint out of the whole machine took quite a bit of time--it was everywhere. Underneath the lint trap was a collection that ultimately ruined the thermal fuse where it restricted the air flow considerably.

Ascertaining the problem was the most time consuming part.

The actual repair was quite simple and didn't take but 15-20 minutes.

1. Removed the screws from the lint catcher
2. Removed the bolts from upper rear of dryer
3. Pried off the dryer top from the front (it rests on rear hinges)
4. Disconnected dryer door wiring
5. Removed bolt from inside upper front corners; removed front panel (be careful: the edges are sharp and the tumbler will fall when it loses support)
6. Removed broken belt and lint from interior parts; removed tensioner (which had fallen out of place). Note: The newer models have a tensioner pulley; my older model had a smooth semicircle that was confusing at first glance
7. Flipped dryer onto its back (for easier reinsertion of new belt and tumbler)
8. Placed new belt on tumbler; reinserted tumbler
9. Inserted new belt through tensioner, inserted tensioner "legs" into grooves on floor. Note: The belt will pull the tensioner upright when it's inserted properly (which isn't obvious at first)
10. Made sure belt and tumbler seal were properly installed
11. Replaced parts in reverse order
The process took over an hour because I couldn't figure out how to insert the belt through the tensioner. The trick is to insert the folded belt through the tensioner and onto the motor pulley. If I had to do it again, it would take about 30 minutes (including cleaning lint)

couldn't get blower wheel off of the motor. really tight. rounded off the wheel's square hub while trying to hold it still as I turned the motor shaft out. No, I wasn't turning it the wrong way :) I ended up going to the back of the dryer and using the multimax to quickly cut the wheel away from the hub. I love that oscillating saw! Just for fun, I put the motor in a bench vise and got the wheel hub off (in pieces). VERY tight! Ordered new wheel, and the job was smooth sailing from there on. I am guessing that experienced repair people automatically order the motor and blower wheel at the same time(?) BTW both parts were perfect matches for the originals. Not surprised; this has always been my experience with partselect.com!

Started out taking the back off, then found online that access is from the front and much easier to get to. Simply pop the hinges in the back of the top panel and then the front of the top is popped off. From there, it is easy to remove the old belt, clean the innards (found 31 cents) and replace the new belt. It was a little disconcerting to see the idler pulley laying loose inside, but the diagram showed exactly how to put it back in place, with the new belt keeping it in place.

Replacement handle snapped in place very easily.

The issue was the idler pulley. First I began opening up the front panel based on a youtube video but soon realized the model was slightly different and required a lot more items to remove. I saw the pulley in the back with nothing in the way so I put the front panel crap back on and removed the rear panel. There it was, very simple to remove and replace. I'm not looking forward to drum rollers though. Hopefully they're aren't as difficult as they appear.

Very easy once I figured out how to open it up to see what was the matter.
1 Remove power.
2 Open the lint filter cover and remove the 2 Phillip screws.
3 Pry the front of the top cover up to separate the cover from the plastic clips that secure to the top front panel.
4 Remove the 2 nut screws securing the top of the front panel to each side cover.
5 Pull front panel out slightly to detach wiring from the cover switch.
6 Pull front panel straight up and set aside.
7 Remove drum belt from tensioner and motor pulley under the drum.
8 Remove drum by pulling it toward the front between the 2 sides.
9 Locate the 2 support rollers and their mounting shafts. Change the shafts at this point if they are worn. (Mine were OK)
10 Remove the support bracket from the shaft if present.
11 Remove the plastic triangular retainer from the shaft and slide the old wheel off of the shaft.
12 Clean the shaft from any bearing debris.
13 Replace the rollers and retainers.
14 Insert drum through the front side panels making sure the seal on the rear of the drum is centered around the opening and not folded inside the opening.
15 Place the belt on the drum and thread the belt through the tensioner and around the motor pulley.
16 Position the front cover on the lower clips on each of the sides.
17 Re-attach the 2 wires for the cover switch.
18 Pull the drum up so the opening on the drum and front cover align.
19 Screw together the side panels to the front panel using the 2 hex headed screws.
20 Check for binds by rotating the drum several times by hand.
21 Press the front of the top panel down toward the front panel to engage the plastic clips attaching the top to the front. Watch for the lint filter housing alignment as you push the top panel down.
22 Replace the 2 screws to attach the lint filter to the top cover.
23 Plug in machine and test.

Good luck, It s not as bad as it sounds.

I purchased the dryer repair kit with the drum belt, wheels and idler pulley. I watched the instructional videos online and it seemed fairly straight forward. Breaking down the dryer and replacing the pulleys was easy enough. My problem began when I tried to feed the drum belt around the idler pulley. After finishing the job, the dryer would not turn and the sensor light stayed on. I thought something else was broken with the dryer and spent hours trouble shooting other problems that I was having. Finally I figured out that the drum belt was not installed correctly around the idler pulley. However, I could not get it properly installed from the front of the machine so I tried from the rear still with no avail. I finally had to fish the old belt out of the garbage can that I had thrown away earlier. I lined up the old belt with the new one in the kit and discovered that the new belt was much smaller, so I put the old one back on the drum. Here's the lesson I learned...make sure the belts are the same size before attempting to install. The old idler was responsible for the squeaking and that stopped but I am still using the same old drum belt. Hope it lasts.

I found that the dryer would not start turning by itself. Could manually help it start and it would run fine. Anyway, after a new set of rollers, belt, etc. found that the motor still would not start by itself. Ordered new motor and it was taken care of. You have to take the back off, remove the belt and remove the tumbler. After that, it is fairly easy. Two screws hold the motor down and then you can take the whole motor assembly out. Be careful removing the fan as it takes a 3/8 socket drive and it is plastic. Two clips hold the motor to the assembly. Needle nose pliers takes care of it. Replace and all should be good.

actually i found your site before i even looked at the dryer,thats how i knew to check for the thermal fuse.
I ordered the part and it was on my door in 36
hours,pulled the two wires off the old fuse and installed the new,put the back cover on and it has been working ever since,thanks ( your in my bookmarks)

After looking at the schematic to see what was in line with the motor, I found the fuse as the first item. I pulled the fuse out and used a multimeter to ohm out the fuse. Upon using the meter I found that the fuse was bad. I typed into Google my part number that was on the fuse and the PartSelect Website came up as one of the choices to pick from. When the part arrived approx. two days later I installed the fuse by first unplugging the dryer and then removing the bottom panel and removing the fuse from the exhaust by using a small 1/4 inch wrench and pulling out the old fuse. I installed the wires on the new fuse and re-installed and put the 1/4 inch screw back in. I started the dryer after plugging it back in and it worked like it should have. Thank you for the part and I have recommended your website to other people already.

Removed and replaced terminal block, power cord and black wire to timer.

My 14 year old son did it as I supervised! Pulled the dryer out on a dolly, unpluged the dyer, removed 9 hex head screws to remove the back cover, removed and replaced the thermal fuse, located next to the exhust outlet, set the cover back on, moved the dryer back in with the dolly. I had the thermal fuse over nighted to me for a total price of $35, figured I saved at least $150 on a service call by Whirpool.
