whirlpool refrigerator gasket

Hi,
My son and I just replaced the door gasket on our fridge. It looks like it is fitting well, but it is not sealing. We are beginners! Please help.:o
Thank you!

Your model number is incomplete. It may help to have the rest.
Make sure all the door hinge parts are in good shape.

the full model no. is EL7ATRRK501. We taped it closed overnight and it is better, but still not sealing on the bottom. I’m wondering if we should loosen all the screws and tighten everything again in the diagonal patterns recommended on this site. Or should we take the door completely off and lay it on a flat surface? Any help is appreciated.:rolleyes:
