The Lost Fuse

19 posts in this topic

a few years back i had two kenmore elite stackable laundry systems [model# 110.92964100] ..... one to use and the other to raid parts from. I need the one I raided for parts from now and ... so, must piece the 'ol fellar back together. I have one mystery that I haven't been able to solve. At some point I removed the thermal fuse from the blower vent AND its connecting wires from the wiring harness. I can't remember why I did that and worse, I haven't the vaguest clue where they might have been connected to ... does anybody know where the wires from the thermal fuse go?

They usually break the motor circuit, surely from 2 machines you have AT LEAST one diagram ? :wacko:

usually, especially on similar electric models, but not on this one.

Thermal Fuse wires:

Black to Operating Thermostat

Red/White to Thermal Cut-Off

thanks ... i'll try that (i've since lost all schematics and docs that may or may not have been attached to either machine ... or i purposely hid them from myself for fun)

Ok, big troubles in little china ... Sears uses a different terminology for the thermal fuse i was asking about .... and, so, I asked the right question with the wrong words ... and, perhaps, I should have been clearer. Sears calls it a 'Thermal Limiter' and it is located next to the 'Thermostat' on the blower housing (not to be confused with the thermostat on the heating element box). So, I need to know where the leads from the thermal limiter wire up to. I would include some pics, but haven't figured out how to get the jpegs off my desktop and into this message.

# 50 should be a 2-wire device , with 2 big blue wires (not violet)
# 42 is the 4-wire Operating (Cycling) Thermostat (with 2 small purple wires) and 2 big wires (maybe red and red/white)

Yes! Do you have any idea where the 2 big blue wires go?

ServiceMatters has wiring diagrams for most Kenmore units ... or perhaps I should say they had wiring diagrams before they're now inaccessible.

sorry, I was looking at the Gas version...

here's your wiring diagram

Wiring Sheet - 8528184.pdf

I'll be back later

I assume it is gas, as the electric unit doen't appear to have blue wires, the blue wires (and themal protector) should be in the line between the thermostats and the gas valve

For future reference, we recommend NOT throwing away the blueprint of the machines design (aka diagram), which is included in the unit at the mfrs expense, don't give 'em any idea's - if they thought you were gonna use those for fly swatters, they would surely stop including them as that's an extra 11 cents profit per unit

Something doesn't jive here, in your photo of the operating stat on the blower (assuming by the size of wires it is indeed electric), the operating stat, which has the violet heater wires is switching a R/W and BK wire, by the diagram, you should have a RED and a BLACK wire connected to either side, the black then carries on to the thermal fuse (which is missing) , and your R/W on the other side of that

Yeah, I know something is wrong with this picture ... I'm not sure what I did, but by the looks of it, I'm pretty sure it was relatively harmless ... in this pic you can see the black and the red wired together ... My link3

....I'm thinking that the operating thermostat must have blown at some point and melted the wires and the thermal limiter ... i repaired the wires with the plastic insulated ends and then I must have melted down and cooled off with a few bottles of guiness and decided that it would be in my (and the combo washer/dryers) best interest to walk away and never return unless absolutely necessary.

At some point in the somewhat-nearer-to-the-present-moment moment i realized that 'absolutely necessary' had indeed arrived and so, here we are.

If I understand you correctly, then... i should be thinking that the black and red/white wires on either side of the operating thermostat also run power to the thermal limiter and so, must have leads (which at some point might have been blue and big).

o.k, i think i understand the wiring schematic RegUS_PatOff .... is it saying that I wire up one side of the thermal limiter (#50) to the black line on the operating thermostat (#42) and I wire up the other side of the thermal limiter (#50) to the red/white line from the thermal cutoff (#47)? thanks, by the way, for uploading that ....

NO, that was (mistakenly) for the GAS Dryer version (as noted earlier)
