Home Button Connector Getting Extremely Hot

Hi! I was recently repairing an iPhone 7 screen and everything seemed to check out correctly. I had safely transferred the home button so that it would not lose functionality, and it did not give me notification about the home button no longer working when I booted up the phone with the new screen. However, it was not working.

I disconnected the home button and reconnected it, and the connector became extremely hot and it burned my finger. It was too hot to touch and you could feel some heat coming off of it from the top of the screen.

I tried a second new screen just in case, and it gave me the same results. There is no damage to the connector and nothing in the way of it.

Has anyone else had this issue before? I have researched and have seen people who have had the same issue with the iPhone 6S home buttons in the past, but I have not found anyone talking about this with the 7. Any input is appreciated. Thanks!
