3HLER5437JQ1 Whirlpool Dryer - Instructions

After tearing the back off by removing the numerous 1/4 inch hex screws, and locating the schematic in the compartment behind the dryer controls, I took a multimeter on the resistance setting and tested all the components I deduced were part of the heating circuit until i found the upper limit temp fuse of was open (i.e infinite , OL, how ever your meter will display this). I ordered the kit from here and upon installation found I had a different type of Thermistat assembly then the kit came with, however, the kit did anticipate this might happen and had "some" instruction on modifying the wire harness to accommodate the part. Essentially if you have this older style you will need to do some basic wire stripping and crimping to make it all work. While I am an electrical technician on aircraft, anyone should be able to follow the how-to video on this page(which deals exactly with what I had) and with the proper tools install this part.
I also cleaned out and inspected the rest of the dryer since I had it all open, including looking for burning on the heating element and inspection of the rest of the wiring harness. Finally removed the lint chute by removing the two screws located under the lint basket door, and the nuts holding it to the dryer frame and did a work over on it, finding a lot of compacted lint and debris inside. A can of compressed air helped a lot for this.

The dryer motor quit working. Learned, if you are changing one that is old, get the blower wheel fan too! I could not break mine loose from the motor shaft, and had to bust it off.

To un-screw the blower wheel fan from the motor shaft: from the front of the dryer, grab the plastic fan on the back of the motor with an adjustable wrench, and the motor shaft on the front of the motor with vice grips. Turn the motor shaft CLOCKWISE holding the fan still to un-screw the fan. If you have to remove the pulley, grab the shaft and turn the pulley COUNTERCLOCKWISE with a wrench.

Just make sure to pay attention to the orientation of the new motor in the instructions. If you match the old motor, it will not fit. It is all spelled out in the directions.

If you were to do the Belt Replacement only, here is the quick synopsis:
1. Unplug dryer;
2a. Open lint door on top of dryer and remove the two phillips head screws that hold the lint bay to the metal dryer top;
2b. Next remove the two brakets holding the metal top to the dryer back (one screw on each bracket);
3. Use a flat-blade screw driver to pry off the top of the dryer (leaving the timer and start button area attached);
4. Lift off top and push back to expose just enough area so you can get to the two screws holding the dryer sides to the dryer front;
5. Unplug door switch;
6. Unscrew screws from #4;
7. With door open, lift dryer front (only about an inch) and then pry bottom of dryer front from dryer sides. The bottom of the dryer front is not screwed, just siting on Front Panel Clips;
8. Once the front is off the dryer, simply remove the belt and install the new one. Please note that while you are in here, you may want to inspect the rear drum seal and replace if it is worn to the point where metal is rubbing on metal. This is also a good time to clean out dust from inside this cavity to help extend the life of the bearings on the rollers and prevent dust from accumulating and gunking up the motor, etc.
9. Re-assemble tin the opposite order.
If you have any mechanical sense at all and you don't know anything about dryers, you will be surprised at the simplicity of the dryer.

The dryer wouldn’t turn on at all. It was like it was unplugged from the wall. However, fixing it couldn't be easier. I simply removed the back panel, found the fuse, tested it with an Ohmmeter (to determine that this was the part that didn't work), ordered the part from this website, and replaced the part. The part arrived in about two days. The shipping was a little pricey, but overall the whole thing cost me $20 vs. whatever it would cost me to get someone else to repair it. The website helps to identify the problem, and it is helpful to read how other people fixed their problems. It was so easy and the service was so good, I will definitely use this website again and recommend it to others.

First I removed the two wires from the overheat fuse, then I removed the 1 screw and removed the fuse. I installed the new overheat fuse and attached with 1 screw, then reconnected the 2 wires. I attached the back cover with two screws and tested the dryer. It was working, so I finished attaching the back with the remaining screws and exhaust duct. Installation complete.
Note: Two weeks later I had to replace the fuse again because I had checked the duct pipe and exhaust chute, but not the bottom at the fan. Be sure to remove the flat exhaust duct and check for bulid-up at the bottom under the fan.

1) Removed top of dryer
2) removed belt and drum
3) removed front of dryer
4) popped clips holding down motor
5) unscrewed rear fan from motor (by exposing and holding fan)
6) changed motor
7) changed support rollers and idler pully
8) reassemled dryer

Purchased thermal cut off kit but only replaced the top most thermostat. There were some extra wires wired into the bottom thermostat, that were not described on the video or any other repair user posts. It checked fine on my multimeter anyway.

Put high temperature glue on first, then put door gasket over the high temperature glue and then let it set for 24 hours. It worked fine....

PartSelect sent me three different door catches with instructions for choosing the correct one. I did choose and simply inserted it into the slot and voile! All finished and it works great now! PartSelect had the part delivered the day after my order was placed. I would suggest doing business with them to anyone asking who they might contact for a part. I especially appreciated the ease of identifying and ordering from them. I was able to do all of this on-line via their website.

Found one of the two drum support rollers was badly worn. Found Partselect.com, found my parts in less then 2 mins. Figured that I was in there so I should just replace the belt so I got one of those also. Parts arrived in 3 days dryer as good as new in 20 mins.

1. Shut off gas and disconnected dryer.
2. Opened cabinet. Easy sheet metal screws and fairly obvious how everything goes together. NB: You'll need a block (or a helper to hold things while you run to look for one) to hold the drum while removing the front.
3. The motor is connected with a single harness, so wiring is a snap.
4. Removing the blower wheel from the back was hard. I braced the motor shaft and turned with all the leverage I could muster, but it was stuck. Plan B: Recip saw to cut the shaft. Motor comes out one side and the fan comes out the other.
5. The fan, of course, was unusable because there was still a piece of motor shaft stuck in the thread. This is why I had to spring for a new wheel.
6. Put everything back together and receive wife's adoring praise...

I opened up the dryer as per the instructions I had received from PartSelect tech support. It was very easy to do. The only unexpected thing was that the original belt had snapped and in doing so the idler pulley was actually laying on the floor of the dryer's bottom. I had to figure out how it went, but that only took a minute and I popped it back into place. I held the drum by hand while pulling the dryer face away so it wouldn't fall and then I slipped the belt over the drum and quickly closed the front up again. I aligned the belt on the spot where the old one had been, pulled it through the idler pulley and over the motor and voila. Done. I closed up the dryer and was on to another "Honey Do" project within 20 minutes.

With the dryer taken apart to replace the broken belt it was obvious that the lint seals had not been working properly due to the excessive amount of lint covering all of the inside surfaces of the dryer. The belt idler pully had also moved from its normal mounting position and was laying at the bottom of the dryer. Because the lint had covered the bottom before the belt broke it was obvious to determine where the idler pully attached to the bottom.

Before cleaning I marked the exact location where the idler pully mounted to the bottom of the dryer.

While waiting for the replacement parts to be delivered a vacuum cleaner was used to remove lint from the inside surfaces of the dryer as well as the old fragments of the lint trap housing seals were removed and surfaces where the new seals would attach were cleaned.

Assembling the dryer with the new belt was a challenge due to the lack of support for the drum while getting the new belt in place, lined up properly, threaded through the idler pully and attached to the motor drive shaft. This is how I installed the new belt:

I used a piece of wood wider than the sides of the dryer, drilled holes that allowed for a piece of cloths line rope to be looped through and used to support the door opening end of the drum.

The drum was set on the seal and rollers at the back of the dryer.

The temporary wood /rope hanger was placed at the front end of the dryer resting on the sides with the top of the dryer raised.

The rope was adjusted until the drum rested on the back rollers and the rope like it would be positioned normally.

The new belt was then gently installed under the temporary support rope and around the drum.

The new belt had many kinks from shipping and was difficult to align with the location on the drum where it needs to ride so small strips of tape were temporarily used to hold the new belt in position until it could be fed through the idler pully and on to the drive shaft.

Several small pieces of a cardboard box were used to shim under the idler pully to hold it in its proper location as well as to make the belt attachment to the drive shaft easier.

With the belt attached, the temporary cardboard shims were removed from under the idler pully.

The front of the dryer was attached .

The temporary board and rope hanger was removed.

The tape that had been placed over the new belt to hold it in proper alignment was removed as the drum was rotated slowly by hand to ensure that all tape was removed prior to closing the top of the dryer.

The seals as well as the remainder of the dryer assembly was completed without any problems.

The dryer ran well for its initial trial spin and has dried several loads of laundry since.

Great parts and support Thankyou

First I raised the top of the dryer(after unplugging the power cord) disconnected two wires to the front door switch and then removed two screws using a nutdriver. The front cover lifts up and while supporting the drum set the cover aside. Slide the belt off the drum and remove it. I then removed the two support roller tri rings and replaced the rollers and tri rings and reassymbled the dryer.
It was a very simple repair.

Thanks Mike

I lifted the top of the dryer cabinet, like the hood of a car using a screwdriver to pry it open. I removed the two screws in the upper right corner of the cabinet front. I disconnected the safty switch on the front door. The front of the cabinet can then be removed by lifting up the front off the pins in the base. With the drum exposed you can place the belt on and thread it through the two pulleys on the motor. Consult the diagrams provided on the PartsSelect website for the proper positioning of the belt on the pulleys. After the belt is installed spin the drum by hand one turn to make sure that it is seated properly on the drum and pulleys. Reassemble the dryer in the reverve order.
