Kerr electromelt repair advice


#1

All,

Our Kerr electromelt, model #22359, is on the fritz. As it heats,
the temperature display begins to jump wildly from one extreme temp
to another. I replaced the thermocouple but this did not fix the
problem. I have replaced the electromelt with a newer Kerr model,
but as I still have parts for the older model, I would like to
explore repairing it to keep it as a back up system. 20

I contacted Kerr but have not heard any sort of response. I thought I
would try Ken Kotoski but his website is no longer available. Anyone
know if Ken is still doing repairs? Any other options come to mind?

Thanks,
Brenda for David Lee

Hi Brenda,

Ken and I were in the same business of repairing jewelry equipment.
About 2004 Ken changed from jewelry equipment repair (MPG Repair) to
repairing watches (Yellostone Watch). I may be able to help you get
your old Electromelt working.

Hi Brenda, I have an old manual Kerr Electromelt I bought used which
works okay butthe safety interlock needs to be jiggered once in a
while. Speaking as someone with an electrical background, it seemsto
me that you likely have a short in your ceramic heating sleeve. The
short is somehow causing the resistance ofyour element to vary wildly
under heat. That’s my hypothesis,at least. If Kerr heating elements
are an integral part of the sleeve then I think you will have to
replace the sleeve. Good luck.
