53568mo. # sidebyside freezercoils dont defrost

Is the compressor running? If not - the timer could be stuck in defrost mode. If it is ruinning, then the freezer coil should be cold. If it is choked with frost & ice - then the defrost heater isn't getting powered (bad timer or defrost terminator - or is getting powered but has burned out.

You should allow the ice and frost to melt completely before turning back on again. Typically ice and frost don't build up so bad in a few days time to cause the temperature rise you're describing If getting cold - the compressor and refrigerant is likely OK, if not the defrost circuit is suspect. If compressor running but not getting cold - a refrigerant leak / charge level may be causing the problem.

IS THE TIMER MOVING TO ACTIVATE A DEFROST CYCLE? IF SO THE HEATER MAYBE OPEN CIRCUIT; OR DEFROST SENSOR IS OPEN CIRCUIT EITHER WILL STOP A DEFROST CYCLE HENCE LOADS OF ICE!!!!!

You need to have the defrost cycle checked.( heater, limit stat, timer) If the frig can't defrost air can't move across your coils to cool properly. To temporarily get by until you can get a repairman, use a blow dryer to melt the ice build up. Once melted it will work normally for about 2 days till it freezes up again.

Three things come to mind:
A) High humidity has overwhelmed the defroster & blocked the passageways so air will not circulate. (Put important food in a cooler, turn the temperature dial to off & leave doors open until ice melts out. Generally overnight. Be prepared to mop up excess water)
B) Defrost timer stopped working. (Generally behind a cover panel on the fridge side. Un-plug unit & remove panel to find a small metal box in the airflow path from the freezer. They generally have provision to manually turn the timer wheel with a screwdriver. Plug back in & allow to run & see if the ice melts. If so, the clock motor is shot. Replacements can be bought on-line)
C) Burned out defroster heating element. Generally older units. (Un-plug & put essentials in a cooler. Remove cover panel on freezer side to expose cooling coils. Allow ice to melt overnight, (again, lots of water). In the AM you can see the glass tube enclosed heater coils. All dark & smokey inside, heater is burned out. Replacements on-line for ~ $75.) If the unit is more than 15 years old, consider a more energy efficient replacement.
Good Luck!

your defrost heater behind the inside rear freezer panel is open or the defrost thermostat is bad and the ice buildup on the coils is probably touching the fan blades that move the cold air from the evaporator coil

Your automatic defrost cycle may not be working. Feel the walls inside and if they are hard solid you have ice build up and the fan is hitting the walls or ice making the noise. Unplug your fridge for 2 days and let the ice in the walls melt. Put towels on floor to catch water. Plug it back in and it should run fine for a couple of weeks until the ice builds up again. You have a bad timer and it isn't letting the defrost cycle come on. Defrost cycle are heating elements that melt the ice build up and runs about 10 mins once a day or so. This will give you time to check if an afforable repair can be done or a replacement fridge.

how is the food?is the ice cream getting soft? are you just having problems with the ice melting?you could have a bad water valve,water could be leaking past the valve,overflowing into the bin and will drip down,with the heater it's gonna work or not work when it should,there's a heater in the ice maker also

evaporator coils are iced up on the freezer side. either take everything out of the fridge and unplug it and let it sit for a day to defrost, or remove the inside rear panel where there is frost and (with the fridge off) use warm water sprayed on the ice to defrost it (or use a hair dryer, but just until the ice is melted. do not overheat the metal). soak up the excess water (underneath the fridge, too), and turn it on empty. let it run empty for a day to get it cold, then put the stuff back in. if the stuff is in there when it's warm, the humidity will ice up the coils again.

It could be the defrost timer the defrost heater or the defrost termostat You can check the heaters for continuity or when the freezer is all cover with ice turn the timer (located in the cold control box inside the refrigerator ) untill the compresor stops and if the heaters start glowing the timer is bad.

you are probably getting an ice build up on the evaporator and the drain also blocked with ice. take back cover off freezer and melt any ice off with careful use of a hairdryer. make sure the drain at the bottom of evaporator if free by pouring a little water down it. if blocked with ice, free with hot water and parience. if fault reoccurs, you have a fault on defrost system
