WED9400SW0 Whirlpool Dryer - Instructions

The repair was really easy and I loved the DIY videos they were great, not many tools needed to do these repairs that was great. The only thing is this didn't solve my issue.

Just like the video, just followed the video
Thanks,

The pulley is accessible from the back of the dryer. Disconnect the gas line. Remove all the screws. Also remove the small plate that secures the line cord. Lift the back up and out. I was able to avoid disconnecting the water line. Take a picture of the pulley so that you will have a record of the belt routing. Release the spring and remove and replace the pulley and bracket. Vacuum out the lint. Plug in the dryer to make sure that it works properly before reassembly.

I replaced both the thermal fuse and the thermistor at the same time. That seemed to fix the problem; but after a couple of days the dryer would not start. When pushing the Hold to Start button, the dryer just gave one beep and would not start. I did a resistance test on the old thermal fuse, and it was OK; so I put the old thermal fuse back in and the dryer works. Evidently, it was just the thermistor (thermostat, internal bias) that was broken. Both are very easy to change.

I did what any novice would have done. I took the entire thing apart to get to the gas jet. I did not know about the thermal fuse until I got to the schematic behind the timer and controls. I was a tech back in the 70's and 80's and only worked on electric dryers. Back then I would remove the heater core and twist the coils together to save money. So I had no idea how a gas dryer heating unit worked. So now any one that reads this. You do not have to take the dryer completely apart, I did that for all of you. Just replace the thermal fuse on the back of the unit by unplugging that wires and removing the screws! It looks like a long white piece of plastic with 2 wires to it. You will find this under the full metal shield on the back of the unit. This should be about a 1 hour repair at the most!

Watched Video - very helpful in repair Maytag Dryer working like new now Thanks for your guidance in my repair

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.

I simply removed the rear panal of the dryer. Removed the two wires from the fuse at the rear of the dryer. Attached an OEM meter across the two fuse connections and had no continuity. Ordered a new fuse and recieved it in 2.5 days.Replaced the fuse,reconnected the wires and replaced the rear panal. Started dryer and it now blows hot air and runs like new. I can't say enough about PartSelect. Great diagnosis using their website, the delivery was fast and I recieved the correct part at a good price. Very satisfied, Thanks PartSelect. Fred F

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.

Took the top off and then front off and drum out . Replaced Drum roller and shaft support bolts.

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.

Removed the dryer's back panel and took a look. Had no idea what to do next, so I read up on it. Partselect was extremely helpful to me, the exploded views with the part numbers called out were particularly helpful. So I determined it was the thermal fuse. Unscrewed the screw holding in the fuse and disconnected the electrical supply. New fuse went in really easily. Job took a lot longer than it had to cause since I was in there, I cleaned out the dryer really good.

Why the fuse blew was interesting: had an extension cord routed over the dryer, well it was situated such that it caused the timer knob to bind up. Apparently, the dryer ran all night because of this and blew the fuse. So don't obstruct the knob or you will be replacing a thermal fuse!
