Kenmore doors getting air vaccum and will not open right away

Make sure the doors are closed tight - freezer door may open a crack when frig side closes.

If door is tight, make sure the door gasket makes a tight seal. Often they need to be cleaned (409 is my favorite) or they get twisted. They also sometimes come away from the door in spots. Pay attention to the bottom seal which you usually don't notice in daily use.

I have had that problem when my Kenmore frig was surrounded by too much stuff that prevented air flow to the coils. It was also a problem when I had it on carpeting. I put a wood panel underneath the whole frig and cleared away all the clutter.

the damper vent door between the 2 compartments is not opening to let cold air in from freezer to refrige,also make sure fan is also running to push cold air through this door,a lot of times its either frozen shut from moisture or the door shaft breaks and it jams shut or the damper door motor goes bad,its a 106.xxxxxxxx model so whirlpool produced it for kenmore

You can try and adjust the front legs of the frig raising the front about one or two inches. This will but more pressure on the door seal.
Sometimes if you slam the frig door the freezer door will try and open. Tilting the frig back will help solve this problem.

Look for the return vent near the bottom probably behind the crisper. You'll have to remove it to see the vent. There may be an adjustable flap in to to adjust the meat keeper area. Make sure it's open.

looks like you have a leak in the cooling system, call sears out right away to save yourself from an even more expensive repair.

It sounds like the fan in your freezer is not working so it can't get the cold air to the frig or your coils are not defrosting and it is stopped u and cant blow air into te frig, One way to check if you hear the fan and know that it is working open the frig and put your hand up near the vent to see if you can fill cold air if you can't now open the freezer door if you can feel the cold air or more air r coils then you could before then your coils are stoped up the unit is not defrosting.

try using a hair dryer on the door seal to get it to take proper shape. I was a service tech for years, and this worked every time.

first check your damper door from the freezer to the refrigerator compartment make sure its in the proper position. Then turn off the refrigerator for a few hours until the heavy frost melts away. turn on the refrigerator check the refrigeration cycle, is it working properly, is it going into defrost are the defrost heaters working.

i would check to see if you hear a an blowing in the freezer sect when the door is opened, if you cant hear the fan blowing then there is yout issue, not circulating air up to refrig compartment
