Need advice/help please on replacing fresh food door gaskets.  Customer has had another tech attempt to install them he could not.  He mostly works on Sub-Zeros.  He confirmed they were the correct gasket although he said they looked a little different. Customer ordered the gaskets.  Please advise,  I normally don’t have install issues with refrigerator door gaskets.  I always do try to be prepared especially if an experienced tech went before me and had issues.  Exiting gaskets customer says show some wear but still seal proper.  Is there something special about this type of install?
Thank you,
