WED5100HC3 Whirlpool Dryer - Instructions

I replaced the thermistor earlier, but the code was still flashing. I noticed the heater terminals were charred and pretty well covered in carbon. So, I replaced the heater, the thermostat and thermal fuse and replaced the 3/8" spade terminals on the heater wires. (These are hard to find - most electrical spades terminals are .250. Also, I crimped and soldered these for a connection with the lowest resistance possible). After all that, the code still flashed! I let the explatives fly, calmed down, and ran the control board test. (This is done by pressing "more time" "less time" "more time" "less time" in succession.) The control board was passing all the tests, but the thermistor test, and the only thing is in this circuit is the thermistor, the wires, the connector to the control board, and some circuit on the control board that involves a few resistors and the "brain" chip. So, I checked the terminals at the thermistor, the wires up to the control board and the connector at the board. The control board connector was fairly dust encrusted, so I unplugged it, cleaned the control board terminals and sucked away all the lint and dust. Finally, I carefully removed earch crimp terminal from the Molex connector (the white female connector) and cleaned and bent them to yield a better connection to the terminals on the control board. I put it all back together, and thus far it is working fine.

Open breaker and ensure power was off. Checked heating components for continuity.Found thermal fuse had an open circuit.Replaced High limit thermostat and thermal fuse.Now is a good time time check for free flowing vent piping.I discovered mine was crimped below the floor and caused lint build up and obstructing the flow which could have led to the thermal fuse blowing.I replaced the vent piping as well.My wife says the dryer works better now than it ever has.

Pulled the lower front panel located thermal switch pulled 2 wires removed 2 small bolts pulled switch out set meter to ohms scale and tested between the 2 terminals it hailed the test I reversed for installation of new switch

Removed back panel of the dryer-reached my hand to the back of the motor shaft, put 7/16 wrench on it to hold the shaft while I removed the broken pulley with pliers. Very easy fix-the tech on Utube took the entire dryer apart totally unnecessary. If that is what the factory tells its tech"s to do its no wonder why the labor charge would be thru the roof.

On this model do not try to remove the back. You must remove the bottom front panel and the lint screen unit. You can then loosen the heat coil assembly and rotate it to get to the high-limit thermostat and the thermal unit. I replaced both because I bought the kit. It actually took me longer to clean out lint than it did to replace the parts. A simple remove of the parts with a 1/4 inch nut driver did the trick. Now my dryer works fine.

Determined via multimeter that either the thermostat or thermal fuse were not working, so ordered the kit (best value, contains both parts).Easiest access is from the rear, so removed rear panel and top of dryer (required) and also the vent tube since it was in the way. Unhooked wires from both parts, used socket to remove nuts holding each one on, put new ones in place, re-attached wires. Replaced vent tube, vacuumed entire inside of dryer (good idea). Put back/top back on and the dryer worked/heated perfectly immediately.

With the instructional video the repair was very easy.

I am a retired applaince repairman not recommended for amature to repair this model.

Ordered the fuse first hoping it was just that simple, watched the video for how to replace, first step was to take the back of the dryer off, well I order to take the back off I had to take off the Electrical Cord, as well as he top of the dryer. Only to find out he part I was replacing was not back there. Found the tech sheet attached within he dryer though, and as it turns out only needed to take he front bottom panel off. Without testing he continuity I was just giving this a shot, the Thermal fuse did no fix it, so I tried the high Limit Thermostat and Fuse kit still no luck. Took out the Element to find I was physically cracked in 2 pieces, replaced that and I was back up and running. And all parts were found in the bottom front panel of the dryer, so beware before you watch the video and take our whole dryer apart like I did.

Replaced with parts orded worked fine for2 hours and quit heating again

Called a appliance place. They said it was a serious problem with master board and it was gonna cost 425.00 dollars. NO THANKS. Ten minutes to open ten minutes to find the problem. ( which was no were near the master board). Seconds to find and order the parts on partselect.com. got it next day. 15 to 30 minutes later my dryers running like it was brand new! Love it.

I removed the back of the dryer and then unscrewed the thermostat and fuse from the heating element shield and replaced with new ones. I simply reattached the back and did a test drying run. Good news, no overheating. Easy-Peasy

Removed existing parts and replaced with new high limit thermostat and thermal fuse kit,replaced flue and tested. Worked like a charm.

Had previously replaced the heater coil (purchased from PartSelect) and fixed the no heat problem. Should have taken advice given on this site and replace the thermostat and thermal fuse kit at that time. Since I knew how to remove the assembly it was easier this time. Just remove, unscrew the two parts and replace with the new ones. Reattach the wires and reinstall the assembly and it is now working again. Also vacumed the inside and trimed and replaced the exhast vent hookup for less restriction.

C/0 both thermostat sensors and fixed dryer Had no heat out ohmed out the coil and it was ok So I ordered both sensors and replaced them and dryer worked great
