Yes,

you have a defrost problem, three things..

one, defrost heater could be bad,

two, bi-metal could be bad,
and three, the timer could be bad.

any of these three items getting bad would result to one symptom.

ice buid up at the bottom of freezer section.

tnx 4 using fixya,

Hotpoint Future fridge freezer - freezer working well but top of the back of the fridge has a large build up of ice ??? And doesn't appear to be keeping the food cold enough


here are lots of things that can cause cooling problems. One of the most common causes of poor cooling in a frost free refrigerator is a defrost system failure. In such a case one or the other compartment may appear to be keeping proper temperature but that too may change in a short period of time. The fridge compartment's temperature rise is usually (but not always) the first to be noticed. Frost" and "Ice"
There is a difference between "frost" (a white, snow-like substance) and "ice" (usually clear and solid). When referring to what is seen during an inspection, please keep this distinction in mind as the possible causes for each are often very different. The Defrost System
Inspecting the (usually rear) wall of the freezer compartment for a frost build up is necessary. (In the case of many GE top freezer models, check the freezer's bottom panel.) If there is a frost coating on it, it is often a sign of excessive frosting beneath it. Sometimes however the evaporator cover panel will actually need to be removed (see the illustration below) before an excessive frost build will visible.
The refrigeration system's evaporator (cooling) coil is usually in the freezer compartment. This evaporator will periodically frost over and have to be defrosted by means of a heating system. When the defrost heating system fails, the frost can accumulate to such a degree that airflow throughout the appliance is hampered. There may be just enough air circulation to cool the freezer section but that will eventually stop too.

Fridge is cold, freezer is not


Please look into the freezer for frost build-up on the rear wall. If you are having a defrost problem it may limit the freezer temperature and still be cold enough for the fresh food section to remain at safe temperatures but not for long before freezer and fresh food section warms because frost blocks airflow and the evaporator is unable to keep everything cold because of frost build-up. I don't have your model number so I will list the parts that may need to be replaced. The defrost control=> 12002754 Frost Kit, defrost thermostat and 67002493 Defrost Heater Assembly

For testing of the defrost thermosat and defrost heater refer to the same page as the parts, If these parts are good the the 12002754 Frost Kit, could be defective. The 12002754 Frost Kit,
can be found in the control panel inside the fresh food compartment. Let me know if you have questions and also if you are not having a defrost problem, Thanks Sea Breeze

Frost is building up in bottom freezer. Appliance is running nonstop. I believe that the freezer drawer has been shut completely. Foods in refrigerator section are fine; foods in freezer section are...


Frost can build up for multiple reasons. Most common is the start os an iceblock. Other reasons can include condensation from door being left open or opening too much. It can also happen from backsplash from the inlet tube for the ice maker. If the fridge is running non stop. It sounds like the ice block is forming and the temps are not getting to the program temps. If at factory setting the freezer should be at or around 0 degrees and fridge should be between 42 and 48 degrees. Has the fridge shutdown at all to go into defrost? The defrost timer may have went out and is causing an iceblock. If there is an ice block always change bimetal/ defrost thermostat.

If you need any further assistacne please feel free to comment me.

G.E. Bottom freezer evap drain keeps freezing up and ice build up stops fan so no cooling in fridge compartment. How can this be solved?


When the freezer section gets cold and reaches its required cooling temperature, after that the frost on freezer section starts defrosting and the cooling fan in the freezer section blows this cool air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the freezer gets cool but fridge section does not cool.Its defrost problem. Try manual defrost by unplugging the refrigerator from main power outlet for 24 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section. You can get required parts from www.repairclinic.com or from online sears part site. ------------- Thank you.

Our top mount Kenmore fridge (Model # 253.77872509) is frosting up in the freezer section. Have turned off & defrosted the freezer on several occasions - it works for a few weeks but then begins...


Hi,


Normally when frost build up occurs it's because warmer outside air is getting into the freezer and the moisture from that warm air cools and condensates then freezes into frost or ice. You either have a bad seal like the other listing states try leveling the front a little higher than the back. Or you may have an issue with the defrost heater, thermostat or timer. Do you have a light that comes on from time to time? If so you have an auto defrost unit. If there is no light you may not have a frost free freezer which means you will have to remove the frost manually.

My compact fridge does not defrost and ice builds up in freezer section. How can I disconnect the freezer and not use it?


Lynne, the freezer section is what provides the cooling for the fridge, so there is no way to disconnect the freezer and still be able to have the fridge operate.

With the small compact fridges, the only thing you can do is to manually defrost the unit, when the ice buildup gets too much, which can vary, based on how you use your fridge, how often it gets opened and closed, etc.

Some compact fridge models have a small push button in the center of the temperature setting control knob - if your's has one, you can push that to initiate a self defrost cycle. However, you'll need to have some towels handy to collect the water that will result from melting off the freezer section.

There are not many small, compact fridge units that have the no-frost feature of full sized fridges, as it is more costly to build in all the needed components required to have frost-free operation. Not to mention the size of the fridge gets much larger, because of all the space needed to house those features (defrost heaters, electronic controls, ciruculating fans, control vents, sensors, drip/drain pan, etc., etc.)

Hope you find this Very Helpful and best regards!

Automatic defrost no longer works


If freezer is icing up, you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, defrost timer turns on defrost heating element every 12 hours to melt ice in freezer and allow good air flow.
You can test defrost element with an ohm meter(located inside freezer coils-will have two wires going to a plug connection), if OK replace defrost timer (located in various places depending on make and model

The freezer is accumulating frost. i have


Some models like yours came with a defrost control board and others came with a defrost timer. They should be found inside the fresh food compartment and behind the temperature control panel. You will need to inspect and let me know which you have. Unplug first. If the control board looks or does not look burned it could be bad. The timer can be turned clockwise until compressor stops and should remain stopped for about 25 minutes. and then turn itself back on. If these look good then we need to remove the rear panel inside the freezer and test the defrost element with one wire disconnected to check for continuity. Just to be sure the element has not burned out. The defrost thermostat is connected to the defrost element and will have open contacts inside it above 50 degrees. Do these test with power unplugged and let me know what you find. Sea Breeze

Fridge wont stay cold in the bottom.


Your frost free is not defrosting properly. There should be no ice buildup in the freezer section. Frost in the freezer section stops air circulation to the refrigerator section.
