WGD9400SZ3 Whirlpool Dryer - Instructions

Removed the top panel of the dryer via a couple of screws from the rear. Remove the rear panel swing it open light a door to the right, minding the electrical connections. Removed the belt from the pulley, removed the Tri-ring from the shaft and slid the pulley off of the shaft. The shaft was slightly rusted so I used a steel brush and brake cleaner to clean it up, placed the new gasket, pulley, and tri-ring on, replaced the belt, and put the panels back into place. As the dryer is about 7 years old, also removed the front lower panel and cleaned out unit which had quite a bit of accumulated dust and glitter especially in the vent lines. (3 girls live here). Pretty easy, most screws remove with just the one tool.

remove&replace

Initially confused by instructions provided in that it stated to loosen a brass coupler. Disconnected power. Removed front bottom panel. Disconnected both leads to ingiter. Removed the 2 screws holding igniter bracket in place. Carefully slid igniter and bracket forward and removed from dryer. Removed screw holding ingiter and replaced with new. Reinstalled in reverse.

Dryer is on a pedestal. Opened drawer and removed two 1/4 inch screws on bottom panel of dryer front. Panel drops down and exposes the dryer exhaust where thermistor is located. Removed two spade connector wires and removed two 1/4 inch screws. Installed new thermistor and reversed procedure. For the moisture sensors I used a phillps screwdriver and stuck my head in the dryer and removed the lint screen assembly (3 screws). Removed the spade wire connectors and used a straight blade screw driver to remove the moisture sensor. Installed the new sensor and re-installed the lint screen assembly in the reverse of removal. All very easy - just took 30-45 minutes total.

Watched steve on the video on changing the thermistor a couple times, it appeared to be straight forward replacement. Unplugged the dryer. . . Went through the front, my lent filter slides in and out from the lid so I had too remove two extra screws to detach it. After opening up the front it became very apparent my thermistor was not located in the same location as the one in the video. Dryer needed a cleaning (lint/dust) so I released the idler pully tension on the drum belt and went ahead and removed the drum/belt and shop vac/ blew with compressed air and shop vac once again. Gave my dryer a much needed cleaning since I had it apart. Put everything back together in about 20 mins. Pulled the dryer away from the wall and removed rear cover and presto there it was right next to the dryer air outlet. Replaced thermistor and replaced back cover, inspected out flex hose on dryer outlet, I clean it out (flex) yearly to prevent problems. Reattached flex on both ends, re-positioned dryer, plugged back in, and works great! Definitely fixed my problem. . . Replacing the drum by myself was a bit difficult. Still do able (there's a video on that also. . )

My front- loading dryer is 4 years old and lint screen felt liner never lasted long without falling out. When I received my Part Select I knew the quality surpasses manufacture screen. It is so much better and we are your new customers forever Thank you Cheryl

Removed back panel and tested all components. Everything was good so had to remove front to test last 2 components. Removed front and used brick (handy tool when your working solo) to hold drum up and in place (with full load of damp towels). Defective igniter. Testing all took 10 minutes, replacement took 2. Spent more time opening and putting machine back together than testing and replacement took.

UNPLUG UNIT FIRST!!! Removed back cover. Make sure to note not all screws hold the back cover by closely observing the screw. Take a picture of the belt routing before removing from the idler pulley. Use headlamp or flashlight to light up pulley area. Remove belt from idler pulley by pushing idler assembly towards the right. Use small screwdriver to remove the existing pulley by prying off the existing tri-ring from the back of the pulley. You may have to "feel" the ring since it in facing away from you. Once tri-ring is removed, slide off old pulley and gasket or old second tri-ring. Replace with gasket first, then pulley then tri-ring. Reroute belt. Use picture if needed. Replace back cover.

pull out lint screen, removed 2 screws. lifted top up. removed 2 screws from the front,disconnected wiring harness. removed the drum and belt. located and removed the igniter, sensor, and coil valves. replaced all with new parts. reassembled. now it heats up. i believe that i only needed the coil valves. coil valves not shown on parts list, i purchased later. everything was very accessible with the drum removed.

Just took the old one out and slipped the new one in! That's it! That easy. Thank you!

I highly recommend the videos on this site for repair information. It wasn't exact for the age/model of my dryer but very close. Remove the top panel and then the control panel. Remove the lower front panel and finally the door and main front panel. Unloop the belt from the motor and remove the drum. I found one of the drum rollers was bad, which was causing my problem, but I replace all 4 rollers, the belt, and the idler wheel. Sounds like it did when it was new! Find the video for your model and watch it!!

It was all put together... I just switched them!

Ordered thermal fuse and cycling thermostat

Since the power and gas to the dryer were both already turned off all I had to was open the top of the dryer, remove the front panel, look underneath the drying drum and remove the belt tensioner from the belt and slide the drying drum out. While things were open I took my vacuum and vacuumed all the lint, dirt and loose articles from over time out of the dryer interior. I located the igniter, used a nut driver to remove one screw pulled the igniter from its housing and disconnected the wiring harness. For installation I reversed the process and I was done. I reinstalled the drying drum, reattached the belt tensioner, put the front panel back in place and closed the dryer top. Attached the dryer vent hose, plugged the dryer to the electrical outlet, turned on the gas and walla it purred like a kitten. It even seem to dry faster than before.

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.
