Heating Mantle Problem

Flip - 22-7-2006 at 19:16

Ok, so here's my latest problem with this mantle. It is an upper/lower stage mantle with two plugs. The plugs go into a controller which goes into the wall. I noticed that the wire for the ground does not continue inside the controller. However, the controller does operate other appliances just fine.

So I go to plug in the mantle, there is a big spark, the fuse blows out, none of my outlets work anymore, and I have to reset the power at the fuse box. I tried but I can't seem to dissassemble the mantle to see if there is some bridge... it worked before, but after I left it in the cabinet for a week and pulled it back out, I suddenly have this problem.

I've tried plugging it in three different times, and I hope that this hasn't destroyed it...

Can anyone help me out here?

Alright, so I just dissassembled it....

It appears that two of the insulated wires had *fused*

In other words, the insulation actually melted together to create a contact that was shorting the outlets. So i've stripped the wires now and i'm going to try and fix it... i'll let you guys know.

Problem solved.

Just had to strip the wire and reconnect the proper contacts.

So I guess if anyone has the same problem, that's the most likely cause. And it appears that mantles are fairly resilient to these kinds of problems.
