I have a Samsung double door refrigerater with bottom freezer.The freezer has developed a problem. I noticed there is a frost build up. What might be the possible cause?

Most frostless freezer build up due to door no close completely closed, leak seal, leave it open too long.
-Try this:
-Remove all the inside stuffs then unplug or turn it off, open all door for 4-6 hours then clean and dry and plug back in
it will last for a while.

Good luck

Our Frigidaire frost frost free upright freezer from day one has frost build up on the food inside the packages. The frost is not a problem in the freezer itself, but on the food. Freezer burn occur

Hi Dale Dibb, thank you for your inquiry!

I understand that the food inside of your Frigidaire freezer is getting frost on the inside of the packages. I would recommend turning the temperature up inside of your freezer. Additionally moisture inside of the package would cause frost to develop on the inside of the food packages.

Please assure that all possible moisture has been removed out of the food packages prior to placing the items inside of the freezer. If there is anything else that I can help you with, please feel free to reconnect! -Matt

The contents of the refrigerator freeze even on low settings

One of the most common problems with freezers is their tendency to build up a thick level of frost and ice that can disrupt performance. The ice can form on the hoses and cause the fan to freeze up. While you want the freezer to be cold, too much ice is not good for the freezer or the food inside it. There are multiple reasons a freezer could start to develop frost buildup.

Freezer Overstocked
Frost can build up in the freezer if there are too many items inside of it. Air cannot properly circulate around the freezer, so the areas with the sitting cold air can freeze the moisture. Frost continues to build up and accumulate, which then allows it to spread. If food is stocked up near the fan, cold air can't get past it, and the fan itself could develop frost to the point where it freezes and stops working entirely. This can be prevented by not overstocking the freezer and by evenly distributing food throughout.

Temperature Setting Too Low
The freezer should have a thermostat that regulates how cold it gets. If the temperature is set at too low of a setting, the freezer kicks into high gear, the air freezes outright and frost quickly builds up. Adjusting the thermostat to a higher temperature or level can counteract this problem, but you may need to de-thaw the freezer to eliminate the frost that has already built up inside.

Keeping the Fridge Door Open
Many people keep their fridge door open for extended periods of time while they examine the contents inside to see what they want to eat. This can contribute to frost buildup in the freezer, because the fridge is taking in a lot of warm air during this process and the fan pushes it up into the freezer. The moisture in that air is then quickly frozen, and ice can build up substantially as a result. The longer the fridge door is held open, the more likely this can occur, so the best solution is to only keep the fridge open for short intervals and then to not open the door again for a while.
Hope this tips will help you. : )

Freezer developing frost while the fridge is warm

The frost build up is causing airflow blockage to fresh food compartment. Frost build up is either a sign of poor door seals, door left open, or bad defrost circuit. If after manually defrosting and after a few days the frost reappears, problem most likely is with the defrost circuit.

If you have some background of electrical circuits you may attempt repair yourself or call in a tech.

Defrost timer on your unit is near the light in the refrigerator. Recessed in a hole, turn with a flat blade screwdriver and advance timer until you hear a click and refrigerator turns off. After a few minutes the heater should come on and should hear moisture hitting heater in freezer compartment in back panel.

If heater is not coming on, could be a bad heater or defrost thermostat is bad. Both of the parts are accessed through the back panel inside of heater. Unplug and ohm check for continuity of heater & defrost thermostat. Heater is a cal rod unit, thermostat more likely to be the problem. part #5303918202

Icing up

I've just had a similar problem. I fixed it by removing the large panel on the back of the inside of the freezer. I found a large build up of ice at the bottom of the freezer which seems to have developed because the drain hole at the bottom of the freezer was blocked. I defrosted the ice, cleared the drain and now the freezer is working fine.

My freezer keeps icing up. I took everything out of it thinking I might have something blocked, but the problem persists. Any ideas?

By icing up do you mean frost inside the base of the freezer ? Keep in mind whenever freezer is opened frequently / long periods moisture enters and causes frost to build up - now if your brand / model is a frost-free refrigerator with automatic defrost, then you have a faulty defrost timer - this timer will usually kick in at set intervals or as needed.

If your refrigerator was working fine before and you developed this problem with freezer icing up you will have to get it serviced - and have them check your defrost timer assembly and its heating elements if both are functioning properly. If your model has electronic controls it would be a good thing to check the control board as well.
