I have 10 Kitchen Aid coffee makers that all have the same problem
that I want to repair. The problem is a defective thermal switch in
the heating element. I googled for a supplier/manufacturer for the
defective switch but came up dry. The number on the component is
155431 0 5 0 N T1 318C. Can someone tell me how else I can find a
supplier. If I can't find a supplier, can I just use another thermal
switch from one of the other coffee makers to replace the defective
one even though the component numbers are different? At least this
way, I could repair 1/2 of the coffee makers. The number on the
thermal switch that I want to use as a replacement is 161471 019 190C.
I think the last number on both components refers to the temperature
the switch opens. If I am correct, it should be safe because the
replacement switch has a lower switching temperature than the
defective one, and therefore would open up and interupt the power at a
lower temperature. By the way, all the switches (4 of them) are in
series and therefore if one opens up then the whole circuit is opened.
The one that would open up first is the one with the lowest
temperature rating and for this reason I think it would be safe to go
ahead and use the replacement switches from the other units. I'd
appreciate any feedback. Thanks.
