The yellow wire to the bottom heating element of my Maytag PER4310BA
keeps burning out. The oven stops heating up and I find the las
inch of wire charred black where it connects to the heating element.
I have replaced the heating element once with a factory replacement
but the problem continues. I am concerned that just cutting the wir
and crimping it once again to the heating element connector wil
eventually cause an unsafe condition with the exposed wire touchin
other parts. My intention is to find the cause for the repeate
burning out of the same wire. Does anyone out there have th
expertise to tell me what to fix to prevent this problem fro
continuing

Thank you in advance for your input

The ony time I've seen this is when wires are connected to the element
using spade lugs. The wire is crimped to the lug and the lug is pushed
onto the element's spade connector.

Over time, oxidation occurs with resulting voltage drop and excess
heat.

I've tighted the lugs with diagonal or crimping piers before
installing them. In one or two cases, I've also soldered the wires to
the spade lug rather than relying upon the crimping.

I don't know this oven, but when you first replaced the element, what was
the condition of the terminal on the wire? If it had been overheated and
annealed, the same problem would have occurred

Any appliance repair store will sell you the wire and connectors that
are appropriate for high temperature. Replace the wire if you are concerned.
The connectors hanging in your hardware store probably are not for hi temp
use and will cause the problem you describe.

It'll either be poor crimping technique or the wrong type of
crimp. Or both.

Heating/cooling/oxidation cycles will be hell on connections
if they're not done just perfectly. Secondly, using automotive
connectors with a heating element is bound to not work for
very long.

Probably the simplest/cheapest thing to do would be to take the
wire into to a proper appliance repair outlet and get a new wire
made up.
