Question about Samsung 26.1 Cu. Ft. Side-by-Side Refrigerator with Thru-the-Door Ice and Water - Stainless-Platinum

1 Answer

We keep having to "defrost" our refrigerator. It is five years old. A repairman came out and showed us how to take the inside back panel off of the refrigerator part and de-ice it. Why does ice keep building up. Could it need freon? We are now having to do this every two weeks and the freezer is starting to not cool like the refrigerator part does.

A lack of refrigerant or a compressor problem might be the cause of freezer low efficiency but that is unlikely to blame for the buildup of ice in the refrigerator.

A certain amount of ice is normal and initially in the evolution of the fridge there was a need for routine deicing, typically just a few times each year. Later a heating element was included to ease the task of defrosting.
These days the heating element is now automatically switched on briefly every time the cooling cycle finishes and the resulting water drained into a cup mounted on the compressor. The heat from the compressor evaporates the water and the fridge remains frost-free.

I expect your fridge should be frost free and clearly the auto defrost is not working. This shouldn't be a great problem and if everything else was good it would just mean routine deicing like the early days. Clearly everything else is not good and the buildup of ice is much more than normal.

Assuming it isn't caused by an elementary mistake like placing hot food in the cabinet there are two main causes of excessive ice buildup - one is a defective door seal and the other is failing cabinet insulation, the latter marked by the compressor needing to run longer to maintain a low temperature and parts of the outside of the cabinet feeling "chilly".

SOURCE: My refrigerator is warm and ice build up is happening in the fridge

There is a timer that controls the refrigerator defrost cycles. This is located behind the kick panel at the bottom of the refrigerator. Remove the panel and look for a dial-like device toward the front. Try to manually turn the timer dial and listen for an audible click. No click, no defrost. Call a NEW repairman and have him check the defrost timer. Hope this helps.

SOURCE: Samsung RS22NJSH Freezer Fault

hi there the fault you have is very common these units do automaticaly defrost to clear ice from the evaporator the problem that they have is when the defrost heater comes on it overheats and blows the safety thermal fuse resulting in the evaporator getting more and more iced up, to cure the fault you will need to replace the thermal fuse which has now been modified and the defrost sensor.

hope this is of some help

SOURCE: The refrigerator portion has quit cooling.

I have the same problem and have found that if you take the panel off inside the refrigerator and with a blow dryer defrost it. It should work for a few weeks. I have been doing this once a month since March and I hope to found out how to fix it also.

SOURCE: frost build up behind/inside back freezer panel

I have same problem, it usually happens after someone leaves door open too long or after 4-6 months. I usually place two frozen milk jugs full of water in the upper fridge and tape the upper fridge door closed at night before bed so the kids don't open and let the upper food get warm., Unplug the fridge and open the freezer and remove all drawers (place excess frozen food in freezer in garage) , leaving the freezer open with a towel in the bottom to catch the melting water from the back panels inside and the next morning wipe the fridge bottom clean and plug it back up and replace everything. I hate that I paid so much for this fridge and have to defrost a couple times a year. However found out too late to return back to the store. It seams like it should have a cycle that heats the back plate every so often to warm and evaporate the ice that collects, but I haven't heard or can't find anything on that.

Our GE Monogram all Refrigerator is freezing up on the bottom in the back. I had this problem one year ago and the repairman first said it needed cleaning, and then when it did not correct after cleaning,...

The reason why your unit is freezing up is due to your unit haveing a defrost issue. A defrost issue is caused from either the defrost thermostat, the defrost heater, or the defrost timer or adaptive control unit having a fault condition. In order to access the defrost thermostat and the defrost heater you would have to remove the rear panel on the inside rear panel click this link the defrost thermostat is labeled on the diagram as number 7500 this is also a parts list labeling all the thermostats in the unit as well the defrost heater is part 5001 on the diagram these component need to be tested for continuity using a mulitmeter. Any part that did not show that they had continuity you would replace. If both parts showed that they had continuity you would look at to perform the same test on 237and 7327. If these two thermostats also showed that they had continuity then you would look at the hmi control which is the control board in the unit as having a fault situation. Your hmi control board is your adaptive control in the unit. If you have any further questions message me back. Please also remember when our chat has fully concluded to rank how this opinion has helped in your appliance situation it allows me to continue helping others in similar situations in the future. Thanks I await your reply if you have any questions

Ice is melting in 14 year old amana refrigerator. Should I look into replacing or calling a repairman?

I would see if the old girl still has a chance at life before replacing it. First, make sure that the condenser grill (under your refrigerator) is not extremely dirty and that the fan is operating. Make sure that you have good air flow from front to back. You would be surprised how much lint, dog hair and lint will accumulate on the inside of the back panel. Clean it out!

If that isn't the case then I would check for ice build up behind the inner panel of the freezer compartment. If there is, then your defrost system is not working and you will need to figure out which component needs to be replaced (defrost heater, defrost thermostat or the defrost timer).

If you do have ice build up then you can defrost the system by unplugging the unit and using a hair dryer to melt the ice, but be ready for the amount of water!

I have a old Amana that I bought in 1983 and it is still working great! They have excellent components that stand the test of time.

The refrigerator is 8 years old. the refrigerator

Any refrigerator should last around 14 yrs. The freezer must be frosted up. I would try to defrost it and then start it back up. If you have a defrost problem you will see this again inside of a week. Also make sure the evaporator fan is operating.

Freezer/Refrigerator tempurature swinging wildly

The compressor is overheating and not starting. Could be just the start relay. If this happens again try unplugging it for about an hour then it should work for a while. Heat between doors is normal this is an electric heater designed to keep the doors from sweating. You just noticed it because the refrigerator wasn't cold.

Kenmore Top Mount Refrigerator - leaking water from the Cold Control Defrost Timer/Automatic Defrost Control Housing

It freezes up for a few reasons. First the water is not running down fast enough. That is why the wire was added to add heat from the heater to the drain hole. The metal pan under the evaporator coil may not be lined up with the drain hole well enough and holding water there. If that looks ok the drain tube that runs down the inside back of the unit might be slightly restricted. Not much you can do about that. I would make sure that the aluminum wire goes in the hole about 2 inches and that the unit is tilted slightly back to help water flow.

Fidge is icing up inside on the rear

Defrost problem, advance into defrost to see if heater comes. If it does replaced timer, if it doesnt you will need to check heater and defrost thermostat.

Check the back wall of your freezer section to see if it is icing up.  If so, you have an automatic defrost problem.  One or more of your defrost components (timer, defrost heater or bi-metal) has failed.  If there is little or no frost on the back wall, you could have a compressor related issue.  This is often indicative of Frigidaire refrigerators.  If the unit is less than five years old, the compressor is still covered under their warranty.  If it is the compressor and it is more than five years old, start shopping.
