For Whirlpool Dryer Heating Element Connecting Wire (Part Number: OEM9403923)

Missourimom for Model Number LER5636JQ0

Dryer was running and popped loudly, the wall fuse trip, but dryer shut off and timer knob froze in mid cycle, could smell burnt smell. The wire from the thermostat to the heating element was burned apart. It separated at the thermostat end. It usually connects to the bottom of the thermostat in a piggyback connecter with an orange wire coming from above. I'm not sure if I can get the wire out of the piggy back one. All other wires look okay, except for one that is corroding at its connector, the one that connects from top of thermostat to the internal thermostat over by the lint chute. There is the look of a flash blast at thermostat/heating element connectors, outside housing of the heating element. Heating element tests just over 1 when analog multimeter set at 10 ohms. Thermostat tests at 0, as does thermal cutoff and thermal fuse. I replaced the heating element connecting wire Nov 2023 due to similar problem, melted wire. Replaced the heating element in September when the old one broke. The new one going in was all shiny; now half is a dull metal...assume that's just from the heat. Isn't drying as well as I would expect, having to run sometimes a bit more, but improved full venting clean out, not best, but good. Do you think it is just the connecting wire that failed (even so soon) or something more? What would be causing the corrosion on the other wire, just age? Where can I find the piggy-back double connecter?

Hello MissouriMom, thank you for contacting APP,

If you are having continuous issues with the element failing and wiring issues it is likely that the Main Wiring Harness 3394290 has damaged wiring that may be grounding out. The Heating Element 279838 reading just over 1O also indicates that the element has failed as it should be reading 7.8-11.8O. The double connector should be 3354925. Additionally, I would recommend having the source electrical supply to the unit tested under load(with the unit running) by an electrician to make sure you are not experiencing line voltage drop/reversed polarity/grounding issues.

Chris,
Make sure the blower wheel is not damaged or no lint in that area. Disconnect the vent behind the dryer. Run a load for 60 minutes timed dry. If your clothes are dry when the cycle is finished then there is a blockage in the vent. It does not have to be fully blocked to affect the dry times.

Fix It Mom for Model Number whirlpool LER5636JQ0

Purchased Heating Element Connecting Kit per previous suggestion regarding a burnt wire, but the video shows a bit different fix. My wire goes from heating element to the lower end of thermostat, but requires a double type of male/female terminal, to connect it and the orange wire connecting from the top of the dryer together then attach to thermostat. The thermostat terminal is also smaller than this end piece. I'm not even what to call that double terminal or where to find one. Second question, I just recently replaced the heating element a couple months ago. It tests 1 ohms continuity on x10 setting of analog multimeter versus 0 like all the other parts. Previous answer said may need cleaned or replaced...so this result on multimeter seems to show it still has continuity. How would I go about cleaning it?

Fix it mom, the wire in question is a jumper wire that comes in the thermostat kit 279816. The kit also includes the piggyback connector referenced. However, if the piggyback connector is on the orange wire, the new connecting wire can be used to splice onto the good section of wire that is connecting to the thermostat. If the thermostat side is damaged, the thermostat kit would be needed to repair the wires in question. In regards to cleaning the element, a vacuum can be used to clear as much lint off as possible. Removing the element 279838 will allow for a more in depth cleaning of lint.

Michael Goodwin for Model Number 11060812990

My thermal cutoff switch had a burnt wire so i bought the kit to replace it and the upper limit thermostat. First off, i dont have the orange wire that i see in videos that connects to the older style upper limit thermostat. The newer thermostat has two terminals but doesn't connect to the heater element the way the old one does. I was going to use the jump wire to connect from the lower terminal on the thermostat to the heating element terminal. will this be a safe way to install the newer upper limit themostat.? the old one had a metal extension with a kind of double connector that fit over the heating element terminal and had a terminal that the orange wire was connected to. not sure what that orange wire in the video goes to from the upper limit thermostat. Thanks for any help. Mike

Michael,

You would just use the jumper wire to go from the thermostat to the heating element. This was a design change that the manufacturer made to do this repair.

I'm sorry but we will need to ask you to post a new question including the model number from your units' I.D. tag so we can recommend parts that can be guaranteed to work properly on your unit. Thank you for your patience and understanding in this matter.

Hello Dwayne,
this occurs due to poor/loose contact between the wire terminals and the heater terminals, the poor contact area causes resistance which turns into heat. Usually, you need to clean or lightly sand the heater terminals and replace the wire terminals with new ones and cut back on the wire if shows signs of overheating then install the wire terminals.
