WGD9400SZ3 Whirlpool Dryer - Instructions

I followed the very informative video and wrote down step-by-step notes for myself. The repair went very smoothly. The only thing I didn't realize, was that the dryer has 4 rollers, not just 2 shown in the video. All are easy to access once you disassemble. I had to do it twice since I had to order 2 more rollers in order to replace them all. Also, the triangle plastic washers come with the roller, so you won't need to order them separately like I did. I also changed the idler pulley roller while I was in there since that has bearings too. Just as easy. I'm very happy with my quiet dryer! One last note: The new rollers are a bit louder than normal at first, but they quiet down very quickly as you use the dryer. It must be because they are brand new.

I removed all the panels, removed the tub, replaced the pulley, put the tub back in and replaced the panels. Just when I screwed the Last screw in the doorbell rang with the door switch which I installed immediately.

sounded like a pair of shoes was in the tub every time i started it no matter what size the load was. Replaced the back two rollers first and decided to start it to see how it sounded. We were glad. Only the back rollers were bad and the dryer was quietly running again. We would suggest replacing the back rollers first to everyone because the front rollers are more complicated to replace and they may not have to be at all.

YOU NEVER SENT ME THE PARTS!!!
I had to drive to a parts store to find them. On January 17, 2024, I tried to call you when the parts did not arrive and your recording said there were no reps available and you hung up. WE CANNOT GET HELP TO CANCEL THIS ORDER. We have been going in circles with PartSelect and shipping. SO, how do I get my refund of the $107.26 for the parts that I never received!!

Remove old filter
Vacuum out
Install new filter

Not a handyman but this was an easy and cheap fix. Now the automatic settings are working and drying much faster. Unplug machine, front panel has 2 spring clips toward the edges that you stick a flat tool into and pull on the panel to open. Pull off the electrical connections from the old sensors by the right side of the lint screen. Needlenose pliers help with the one farther up there. Then just pull the old ones sensors out, stick the new ones in, reconnect the electrical and get ready to live the good life with dry clothes that don't smell musty.

Simply followed the video that accompanied the part confirmation. Removed the top and front of the dryer. Removed the drum and belt. Unbolted (1 bolt) the Idler pulley and bracket and bolted on the new one. Reversed the sequence of disassembly and tried it out. The only minor difficulty was slipping the belt over the idler pulley after the drum was in place. This is where a second set of hands might be helpful to hold up the drum, while the other person puts the belt in place. Other than that, this was a simple repair and probably saved a couple hundred dollars for about 1.5 hours of my time. Thanks for the video...it was right on point, and made the job much easier.

remove top, front, drum, fan fan housing, replace motor

Checked fuse with Volmeter, had continuity (acted as a short) not the problem. Disconnected Hot Surface Igniter 2 Position connector to check resistance for a range of 50-300 Ohms of resistance with Voltohm Meter. Meter read open (High Resistance). Removed Igniter by unscrewing 5/16" hex nut on igniter plate assembly and noticed silicon carbide element was cracked in the middle. Ordered a new igniter and noticed assembly was required. Be careful here as igniter element is fragile, also do not touch it with your bare hands. You have to lay down on floor to reinstall igniter assembly and you might want to practice anchoring the defective igniter to gain confidence. Finally with slow movements anchored new igniter assembly and turned on dryer. Watched igniter glow heating gas valve and heating gas flame returned. Dryer fixed for a few hours of study online and cost only $24, plus learned how the gas dryer works.

Unplug dryer from 220VAC outlet

Remove bottom cover panel, slip a flat blade screwdriver into each clamp, and bottom piece becomes removable. Pull forward and lift bottom cover piece.

Pull up top section from dryer frame. Disconnect dryer door off/on contact three wire switch by pressing plastic connector together. You may need a small flat blade screwdriver to seperate connector.

Remove two Torx (T15 head) screws in the far left and right corners of the front door panel.

Remove two screws underneath dryer lint screen, be careful to not let front door and front cover fall forward. The rotating dryer drum will now be loose.

Underneath drum, there is a cover panel over the dryer motor. Likely you will find a bunch of lint all about. This dryer had likely not been cleaned in many years.

Remove screws on dryer motor cover.
Remove panel. Likely, you’ll more lint about.
After vacuuming, use a flashlight and hand mirror to locate belt tensioner, back side of motor. If your belt is not broken, press down on the tensioner spring and remove belt from tensioner and motor. Inspect belt, replace if worn. In this instance the belt was well worn.

Slowly pull dryer drum forward, walking belt along as you bring drum forward out of the dryer casing.

At this point you have plenty of room to access the one bolt holding the tensioner, in this instance it was a 13mm socket. Be careful to remove the tensioner springs before removing the bracket. Your PartsSelect is an identical match to the original one.

Install new tensioner, tighten slightly, then put springs back on.

Reverse this entire process to get your dryer back together and back running smooth and quiet as it was when new.

This dryer was quieter than its owners remembered it being back when new 15 years ago.

Well worth saving the $ doing your own work.

Good luck on your repair endeavor!

Took the old parts out and installed the new parts in , everything that you sent fit perfect!!!!!

Removed the screws replaced the belt and lubricated the wheels and that fixed my Knocking and it runs like when I first got it

Removed the front panel, removed the tub and removed the old seal. Tub seal area was scraped, sanded and wiped with acetone to ensure a clean. Bonding surface. Applied adhesive with and acid brush to get a consistent adhesive layer without getting too much in any one place. Seal was a bit smaller than the tub circumference so it had to be stretch to fit. While the adhesive was curing , I took the time to clean the contact surfaces and vacuum the lint from inside the cabinet. Reinstalled the tub, drive belt and front panel.

Removed the dryer door, unscrewed lint vent.
