My electric iron is Aetna letter 936, the handle is 2 lines of heating core, but I bought a four wire heating core, how to modify it?
What did you do later? I have the same situation. Can I use it instead? How can I get the connection if it can be used instead?
Use it. It's not bad. The two lines are temperature control lines
The constant temperature iron is thermocouple, and the other two wires are thermocouple..
