Not heating but jumper wire works

Why does jumping the black and blue wires on my Samsung dryer make the heat work? Without them jumped it doesn't. I'm actually working on this dryer for a friend. My current dryer works fine, so I assume the electric going to and from the dryer is fine. I saw other posts mentioning where they were recommended to replace the control board. I don't want to put that cost in. All I know is when I jump the black and blue power wires it works fine. All sensors tested within specifications. Does anyone have any advice on what this could be? The dryer is only about a couple years old and all wiring looks like new. The dryer has been thoroughly cleaned and looks like new inside and out.

How do I know if my heating element is bad on my Samsung dryer?

The expression "jumper wire" basically alludes to a leading wire that builds up an electrical association between two focuses in a circuit. You can utilize jumper wires to alter a circuit or to analyze issues in a circuit.
