Appliancefregerator: freegerator ok freezer not as good
My freg is on top freezer on bottom freg cools good but freezer not as good won't go much more than teens ?
Is this a good question?
Once you've decided that it's not your imagination and your freezer really isn't cold enough, don't stand there with the door wide open, scratching your head. Don't turn the temperature knob all the way down, because that will likely make the problem worse. The first thing to do is make sure the compressor is turning on. If the appliance is humming away as usual, it's probably turning on. Next, make sure the freezer isn't overloaded and that the evaporator fan is blowing air inside the freezer. Air needs to circulate around the compartment, and cramming it too full leads to problems. Then, make sure there's room for air circulation on the outside of the appliance, with at least 1 inch of space at the back and a few inches at the top. Finally, plan to cook some of the frozen stuff for dinner, just in case things don't work out as desired.
The Most Likely Causes
You've already checked for a few common causes: compressor, fan and airflow. If those are ok, it's time to check for frost buildup. On an automatic-defrost unit, you can't see if the evaporator coils are frosted over, but if you see frost buildup along the walls of the freezer compartment, chances are the coils are choked with frost, restricting the airflow that makes the freezer cold. On a manual-defrost unit, you might see so much frost that you'll realize why your freezer space has been steadily dwindling. Defrosting a manual unit will probably solve your problems. With an auto-defrost unit, defrosting manually can help you diagnose the cause and may get things working again, but you'll likely need a new part or two for a permanent fix.
Other Things to Check
Before you commit yourself to an old-school defrost, check out the following possible causes:
Door seals—you shouldn't feel any cool air when running your hand along the edges of the closed door.
Dirty coils—if you haven't cleaned behind the freezer in years, roll it out and vacuum the backside with a soft brush attachment, to remove dust and debris that restricts airflow.
Ambient temperature—extremely hot weather can make a freezer warmer, especially if you're opening it a lot or frequently adding new items. In very cold weather, a freezer in the garage may heat up, since there isn't enough warm air for the system to work efficiently.
Time to Defrost?
A manual defrost is easy, if inconvenient and possibly messy: Move everything that's worth saving to your neighbor's freezer (eat or pitch the rest). If it's a freezer/refrigerator, you have to move all the fridge contents, too, since the cold comes from the freezer alone. As mentioned on Hometalk.com, a social networking site for home improvement buffs, if your freezer is full of frost, the air intake to the refrigerator could get "iced over and blocked."
Lay a bunch of towels under the unit (even on automatic-defrost units, in case there's a lot of water). Turn off the freezer, open the doors and let it sit for 24 to 48 hours. When it's done, turn the unit back on to the normal temperature setting. If the freezer is an auto-defrost and returns to its proper coldness, you could have a problem with the defrost timer, defrost heater or defrost thermostat. There's also the unlikely possibility that you have a leak in a refrigerant line. Time to call a repair pro in any case.
