Wire question -- aluminum and copper
#1
Posted 20 May 2005 - 09:40 AM
I have the above range.
It's a GE badged as Kenmore, I think.
Two of the elements have gone bad -- one was bad when we moved here 2 years ago and we lived with it. Now another one has fritzed.... Spouse won't tolerate.
Here's my question:
I can get two of the elements for about $120 and replacement looks easy. PART# WB30T0006 or WB30T10047
But, is the life of the other two larger elements limited?
I can't read the date code from the model but I know you can..... ha ha.
Should I order the bits and keep the beastie or scrap it to our local recycler/rebuilder?
Advice is appreciated.
p.s. I am a returning amateur but first time poster. I fixed my own washing machine for $11 and scraped knuckles based on great advice from you sensei.

I popped the top just to make sure I could do the job easily enough.
One of the elements had a small break so I tucked it into the rest of the element and it appears to be fine (I doubt it'll last). The other one (the one which was bad in the first palce) appeared to be broken in many places.
I will replace the other and see how I do.
Thanks!

I ordered the part and it arrived.
Here's my problem now...
There is a difference between the replacement part and the existing one.
The difference is two-fold.
1. The connections are different. The old part has a main four terminal connection. One of the terminals has a small black pigtail to a second connection which provides power to the element itelf. The other pole on the element is an orange wire [this second connector is visible in the photo], The new part doesn't have this type of connection -- I can see that the power for the element comes out of the 4 connector block [see photo of new unit]
2. The physical form of the element is different -- the parts sites all told that the original part # WB30T10006 had been replaced with WB30T10047. The difference is that the original element assembly sits up on three spring loaded posts -- the new part doesn't have the holes/assemblies to take these posts. [OOPS -- later post, I figured out how to solve this, the post supports screw in to the base, I should have looked harder]
So my questions are two:
1. Is there a way to adjust the connections? I can see that the black double connection on one side of the control unit "jumps" to the other elements of the range.
2. Can I adapt the new element to my current installation? For example, can the inner part of the new assembly be transplanted into the old "outer" assembly. [Solved this one]
I will attach photos.
Thanks for any help you might offer.
I don't have a wiring diagram to hand to help with the wiring decision but maybe master sensei's have a sense of this.
Arrigato!

p.s. can't get more than one file to attach so will post three messages to follow -- sorry if that's inefficient.

I can read the basics from the diagram but it doesn't solve my "new unit" connections problem for me.
As usual your help is appreciated.

On the old unit, the terminals are labelled in the way you say.
Trouble is the new one has different labels for the 4 terminals.
They are 2,4,S and H
Pin 4 looks likes buses to the element (as well as being part of the control)
The element is bused to another internal connection labelled P1
[These are the labels are you look at the thermal control from the bottom that are on the left]
The two terminals on the right are S and H.
I end up with an extra orange wire and am not sure if that should be joined to the other orange which connects to the thermal control or what.
I will wait and see what else pops up before I do any "live" tests.
I have to go to work now so I won't be back on until later in the day.
Again, thanks to all!
I can scan the wiring diagram but it doesn't solve the new connections.

Thanks Kdog -- no experiments with 240 volts without higher confidence levels -- I have a lot of respect for 240.
I have your point on the orange wires.
One other piece of info since i last posted.
The cover over the thermal switch was not sealed on very well -- it just swivels open. I can see the two switches inside.... I presume one is for the heat limit and one for the "hot surface" indicator.
I will check for the closed circuit as you note (I don't have a meter for checking R but I do know what it should be from the wiring diagram!). I am not sure what you mean by impressionable terminal.
Not sure which of the black and yellow go to which of the other terminals....
I am at work now so won't get another look until later.
I put it all back together so spouse can use stove but will get another look later
on.
I might post a photo of the inside of the thermal control on the new unit -- that might clue you in. I might also check and see if I can pop the cover of the control on the old unit.
We'll see if any other sensei's give this a read before then.
Thanks again.

Kdog was right!!!
I was careful in checking the two thermal switches inside the controller -- one closed (which opens at high heat) carries the juice to the element; one open which closes at high heat [to indicate hot surface]. I had to splice in a longer wire as one of the connectors wouldn't reach its new position. The switches in the new assembly were set up differently and so connectors were in different places. Two orange connectors (power) on one side -- look for the bus that connects directly to the element. Black and yellow pairs on the other side.
I marked the locations of the "post holders", transferred the little steel plates (the spring loaded posts now fit the new assembly) and popped her in. Put the glass back on top, cleaned the grease from the sides of the stove.... and plugged her in and pushed her back.
Testing time: comes on, heats, hot surface light comes on.....
I'd say a completed repair by an amateur (or hammer chewer).
I will be back and thanks to all who read/looked etc.
Final thought: look for wiring diagram taped to inside of case next to lower drawer for resistances etc.

I was posting earlier about my Kenmore range. (not sure how to link to the posts there but they are down a bit in the list now)
I had replaced one of the surface element assemblies (with advice from this board -- thanks Kdog)
One of the connecting wires was too short so I spliced in a short piece of Romex to lengthen it (just one wire from Romex rated at 600V -- standard 12 gauge).
So here's my question -- the harness on this range looks like aluminum or aluminum alloy, the Romex is copper. I made the connections with wire nuts and then wrapped in electrical tape.
This morning I recalled some vague memory of combining copper and aluminum as being a safety issue -- generating heat etc. The piece of Romex is about 4" long and there are two wirenut connections. Am I OK with this in the context of a range. Pegi told me the range was 1999 year.
Any thoughts would be welcomed.

Just copy / paste the topic heading... :) I do not know the answer to your question so I will defer to someone who has more knowledge in this area.... Pegi
