WGD9400SZ2 Whirlpool Dryer - Instructions

I followed the advice posted by other customers. I took the front off the dryer, put the door back in place and ran a cycle. I could see that the igniter was heating properly, but no gas was flowing. Based on what I read I concluded that it was a problem with one of the gas valve coils. It was relatively inexpensive to replace both (and the dry is 10 years old), so I didn't go to the trouble of determining the bad one. I replaced them both. Obviously I unplugged the dryer (no need to turn off gas). There were 2 screws that held the bracket in place which holds the coils. I disconnected the coils, removed the bracket screws, replaced the coils, reattached the bracket screws and reconnected the coils. I then reattached the front plate to the dryer. It was very easy and took about 20 minutes and I had never worked on a dryer before.

First and Foremost i was told that my problem was with the Thermal Fuse (Fix Ya.com), Then with the little Electrical knowledge I have thought Fuses don't turn on and off,If the fuse was bad i would get No Heat. (Even for a second) Fuses just don't turn on and turn off intermittently,when they go there done! So after a little research i decided to order the gas coil valve. I tilted the top up, two screws on the front panel, took that off and the valves were exposed,(bottom left) two screws too remove bracket then installed new coils on bracket,put back together and I Have Heat Again! NO problems what so ever since new install. I would say having not been for cleaning lint build up inside the machine (been 6 years) the Whole project took me Ten Minutes.

Same as others.
1. Unplug dryer from power source
2. Use nut driver to remove two front screws at bottom of dryer
3. Disconnect cable connected to Secondary Coil (this is the coil towards the rear of the dryer)
4. Use angled phillips screw driver to loosen screws holding cap on top of the two coils. (Angled tool not required but seemed easiest to me)
5. Slide top cap back towards lock screw to allow coil to be lifted out
6. Remove and replace secondary coil
7. Replace cap, tighten screws to lock in place, reconnect cable to coil
8. Restore power to dryer, test and confirm gas flame stays lit
9. Replace lower front panel on unit

PartsSelect a great resource to use for home repairs like these. My first time using site and doing this type of work, now PartsSelect my first source to go to on such items.

Removed and replaced both the thermostat sensor and the ignitor. Tested thej dryer and it worked. Replaced the front panel and it was good to go.

Watched videos on line on how to repair. Replaced all four Drum Rollers, Belt and Idler Pulley, cleaned out inside of unit.

Cleaned out years of fuzz behind lower access panel and noticed where the igniter sits there is a metal tube about 1 inch in diameter. It had rust on the end and was starting to flake away. Found some helpful hints about how to test the igniter. Very easy, just used an ohmeter. Unplugged the 2 pin wire connector and checked for continuity. 1 lead on 1 pin and the other on the other pin., igniter side not the harness side from the dryer. A good igniter should read less than 5 ohms. I don't know the spec. exacttly, but it should not read open or infinite resistance. My meter read an open circuit. Removed the tube and igniter assembly, mine only 2 small bolts. I found the igniter element cracked. Ordered and installed igniter and tube assembly. This was a very easy install. 20 year old dryer works great and it's better than spending $500.00+ on a new one.

Disconnected Power cord, removed vent pipe, removed back panel, had to slide top cover off to remove additional screw holding back on. Went down to where the Idler Pulley was, removed old piece by depressing on the spring loaded actuator and slid it off the belt and all. Replaced same as removal.

removed door by undoing screws holding it on dryer.
Removed all screws on door EXCEPT the ones with star heads.
Separated two parts of door and undid screws holding hinge in place.
Removed hinge and replaced with new hinge.
Put two faces of door back together and installed door back on dryer.

To be honest and explain, I had previously taken apart the door and removed the star screws which allowed the other pieces of the door holding the window to fall apart.
After some difficulty, I was able to put the seal back on and re-install the metal window holders which is why I said it only took 15 minutes after the part arrived and why I accented NOT removing the star screws.
There were a couple of other screws which probably didn't need removing but they didn't cause any problem with the installation.
After putting the door back on, I had to manually twist the door a small amount because it didn't want to keep the button depressed which kept the motor running which turns the basket and heats the clothes.
The door had been causing some trouble for a couple years and we had obviously closed the door with a little extra force when it ''caught'' on the door frame causing it to bend a small amount.
It only took one adjustment and worked fine after that.

Just watch YouTube videos. They show you how step by step. Easy to install. Clean all the dust out while dryer is apart if you can with a vacuum.

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.

I removed the Drier Door and removed the Front Drier Panel exposing the Gas Valve & associated parts. I removed two (2) screws holding the Gas Valve Coils in place & replaced the 2 terminal coil, then replaced the screws, Front Cover & Drier Door. I liked the results so much, I ordered the other Gas Valve Coil and will replace it also when it arrives.

Good trouble shooting information.

After opening the bottom access panel, I found a lot of lint build up which is very flammable. I took my leaf blower and cleaned it all out. Then I just followed the instructions that came with the part. But be careful as the igniter is fragile. I broke the first one...

Replaced coils on gas valve.

After reading the many different common stories,I replaced both coils (m series).Very simply lifted up the top of driver,held by 2 snap springs and 2 lint vent screws.Removed front cover,2 screws and 2 bottom snaps,coils down on bottom left.r/r both coils,reinstalled covers and let there be heat!This website is a blessing!!

I removed the bottom access panel, with 2 hands i reached in behind the blower, i released the belt, i used a screwdriver to pop the retainer from the pully spindle, i removed and replaced the pully, i snapped the retainer back on and replaced the belt. I made sure the belt was on track and all was good. I put the bottom panel back on, it took all of 5 minutes. The hardest part was the retainer clip faces the rear of the dryer so you have to feel it. Also , the space is tight, use a smaller flathead screwdriver to get behind the clip, it will pop right off.
