YWED6400SW1 Whirlpool Dryer - Instructions

I studied the wiring diagram on the back of the dryer. I diagnosed a bad thermal fuse (no continuity). Found the part online at Part Select. The part came a few days later and I was back in business. Great Service.

The Termal Fuse did not solve the problem. Ordered a heating element so I hope its that

I googled the problem and determined that the thermistor was faulty. I found your web site from which I ordered the replacement part. The part arrived within a week. The replacement was not particularly difficult, but the space was very tight (without removing more panels and covers). I just kept at it and got it installed and the dryer works fine now. There are several pertinent videos on you tube, none of which were my particular model, but the combination of them led me to a successful installation.

I made sure air vent was clear and clean. I removed front panel of dryer unit, located fuse, removed wires, tested fuse with ohm meter, which was defective. Tested new fuse placed back in dryer reattached wires. Cleaned out inside of dryer, replaced front panel. Now works like new.

Dryer works - thanks to a new fuse. Glad I tried this before just buying a new one. Video for my model indicated the fuse was located in the back and actually it was difficult to get to in the front. So extra time was wasted trying to get to fuse in the back. Thank you for the part!

Attempt to start dryer normally. Turn timer dial to high heat setting. Press the Push To Start button. Verify plug is secure in wall outlet. Got to breaker panel to verify breaker is not tripped. (Sometimes breaker may trip but visually appear no to be tripped). Reset breaker to maker sure breaker is in the on position. Attempt to start dryer normally. If dryer did not start proceed. Get a multimeter. Remove plug from wall outlet. Slide dryer from wall. Remove exhaust duct from bottom of dyer. Use multimeter to check voltage at wall outlet. Verify 120 to ground and 208 between hot legs. Remove rear cover if main dryer unit and rear of control unit. Connect the multimeter to rear of control panel rear of push button. Turn meter to ohm setting. Push the start button to see if there is continuity. Release the button to verify no continuity. Next major part of curcuit is the thermal fuse. Look on lower left area of dryer. With multimeter in Ohm mode place the leads on the light blue wires. If no continuity replace thermal fuse

There was no heat but the dryer would operate properly in all other functions. I checked the ignitor (gas dryer) with a meter and it was okay. I traced the circut back and ended up at the thermal fuse and it was "open" I jumped it out and the dryer started to work. I knew the problem was the thermal fuse but more importantly why did it blow. Further investigation showed excessive lint in the duct. Needed to take the exhaust system apart and clean out the lint. also replaced the flexible dryer (too difficult to clean) and to make sure that I didn't over work the high/low thermostat and would be doing this repair again in the near future I replaced that also. Be careful and do not jump out the fuse and use the dryer as this will cause a fire. I did it to prove the problem only... Dryer works well again and we will probably get another 5 years out of it!

I ordered the part(and a backup) and had it in two days. 5 days less than ordering from sears.

pushed the broken catch into the door and snapped the new one back in. Works perfectly!

NOTE: Please make sure the dryer is un-plugged any time you are reaching into the access panel with your hands or a tool. There are exposed connections everywhere. After using the diagnostic testing instructions (usually attached to the inside of the front panel) I determined it was a faulty Thermal Fuse. The PartSelect video instructs you to take half the dryer apart to access the Thermal Fuse, but I found it easy enough to just access it with the front panel removed. I used a small 1/4" drive socket to remove the single hex head sheet metal screw holding the Thermal Fuse in place. I then slid the 2 wires off, noting which went to which lug. Installed the new thermal fuse and after starting the screw by hand, tightening with the small socket wrench. It is a bit tricky to reconnect the wires as you are doing it all by feel, but it's a lot easier than taking half the dryer apart. Also, make sure you check the exhaust path for obstructions, that might be why the ThermalFuse blew in the first place.

I tried to remove the part with pliers but could not remove it so I removed the screws that hold the front part of the door. I took the front part off, removed the broken plastic and then lifted on side of the catch so that the bottom of the front part came thru the door and then was able to remove the door latch. The installation of the new part took about 15 seconds to put in by pushing it into the opening where the broken part was removed. I put the front part of the door back and put the screws back and the dryer works fine.

Followed the Video on how to replace,

I remove the back panel then look for thermal fuse.. so easy to replace.. thank you so much ..

This model you cannot lift the top lid without breaking it. Removed the exhaust hose and back of dryer. vacuum out the dryer and hose to remove the excess lint. Remove screws from the lint guard mounting. Loosen and remove 4 screws that hold the lint guard in place. The seal at the base of this assembly was missing the seal around the discharges fan. Remove seal with putty knife. Use a small brass wire brush to remove as much as you can. Vacuum area. Reinstall the lint guard assembly, start at the top, gently life and push assembly up and in. You should be able to determine how far. Start the bottom 4 screws, tight them. Check fit. Then put the screw back in on the lint guard on the top of dryer. Once you have completed this connect exhaust hose. Start dryer, check the dryer exhaust vent that is outside. If the flow is good, WELL DONE!

Recommendation: Check this assembly by removing the back of the dryer approximately every 6 mos. for lint build up. Not doing this may increase the risk of fire.

Replaced all 4 sensors. Still no display. Ran my thumb across all control buttons several times. Machine showed life. Looking good, but low heat. Replaced the heating coil, and now we have a new, 13 year old machine.
