I'm repairing an old Thermador TM45-1 electric cooktop (22" by 45" with two 6" burners, two 8" burners, and a griddle in the center).

It's in surprisingly good shape except for 1 of the 8" elements that is burnt out/rusted, including the wiring/connector. I've spoken to a few suppliers but it appears that direct replacement parts are discontinued or unavailable.

These elements were hard-wired (pic attached) instead of the plug-in type connectors that are more common in contemporary cooktops. Plan is to replace it with a new connector plug (possibly like this one-pic #2), but haven't been able to find reliable info to make sure I choose the right type since most new ones are "universal" but still specify brands (GE, Whirlpool, etc).

Other than making sure it's physically able to fit into the space under cooktop and allow the coil to plug in securely and sit level, is there anything else that I need to consider to make sure it's a safe replacement plug to use?


--In related info for the overall project: I've found some excellent info about replacing the heating element, since there isn't an available exact replacement part for that either.

Special thanks to Jim Stewart's answer to another question (What effect does the number of coil turns on an electric stove heating element have?) who clarified the calculation for expected resistance that can be measured and help make sure a replacement element is appropriate.

  • Make sure to get high temp crimps, I believe they are rated at 900f or close the standard crimps tinned copper will fail in a rather short time as the heat is above the standard crimp rating. I’ve done this with a few elements and used silver solder on others I could not fit a crimp on

  • Great advice - I will make sure to do that. Thanks! Jan 24, 2022 at 1:04
