A technician came out to fix my dryer that was making noise. He fixed it by changing out a belt I think. After he came the dryer was quiet but not heating.  Then he came back and said power source was never installed correctly “a screw came out”
in your opinion was this a coincidence or did he possibly losen a connection on the first trip?
