I have a double-control switch for an electric heating bed，but it didn’t work. The repairman said that the resistance burned out. I don't know much about resistance. So I checked the function of resistor on the Internet, but I still don't understand it.
Let me send you a picture. What kind of resistors I should use? Thank you!

More information will be needed.
It really depends on how the resistor is used.
If it was the heating elements resistance and it is open. The thing is dead.
If it was used in series with the heating element to lower the current into the element to lower its temperature.
If it was in an electronic control to electronically vary the temperature. Better chance it is this.
