Door gaskets are an art! A lot of technicians do them differently, here’s how I do mine.
Tools needed:
1/4 inch nut driver for impact
Impact driver with an extension at least 2 inches
Blow drier
Flat head screw driver (sometimes it helps getting the gasket bead into the retainer)
This can be done with hand tools in a pinch
1/4 inch nut driver
Replacing sub zero door seal “gasket” tips:
1) make sure your gasket is nice and straight out of the box. If you try to install a mangled gasket it won’t work well. Prep your gasket with the low setting of a blow drier while in the box, we want it evenly heated.
2) make sure your gasket is the problem! Just because your machine isn’t cold doesn’t mean you have a bad door seal. A big mistake is removing a gasket on a warm refrigerator, the new one probably will add to your problem as it won’t seal right until cold again (if ever again)
3) make sure your the “bead” of your gasket is installed into the door gasket retainer all the way around the door and not popping out anywhere! No missing screws!!!
4) don’t over tighten your screws they will strip. If they strip I add a dab of silicon to seal the stripped screw hole and tighten as much as it will go
5)keep the screws loose and smooth your gasket out by arranging it on the door into the best position possible before tightening.
6)keep your corners tucked in around the edges.
do what works, remove as many screws as you need. Some technicians remove the entire metal retainer.
