rental property stove only had 2 working burners and bottom drawer off track

first i took out burners then i took out the screws of the termnal block bracket. i then raised the lid on the stoveand clipped the wires on all 4 of the terminal block kits.i then slipped the shrink wrap on wires and used the wire nuts to connect wires together then heated the shrink wrap. I then put screws back in terminal block brackets. I then put the burners on while looking under lid so i would know they were making good connections as this is a bad design from factory. if you pull out burners to clean them and they are not put back in right you dont have a good connection and that causes the terminal blocks to get hot and melt. thats what happened in my case.
As far as the drawer glides they just snap into place
