The coils at the back of my freezer keep freezing up which is blocking the cold air from coming up to the fridge. I've shut off the power twice for 48 hours and it starts working again, but not for long.
I noticed at the bottom of my freezer there is a ton of dust that needs to be cleaned out. But, I can't seem to get to all of it out. My fridge is heavy and it seems that I would need to lift the fridge to clean it out properly.
Could this dust be causing the problem???

All the big cooling happens inside freezer compartment. Freezer gives little cool air to fridge compartment. Now when the vent blocks that little cold air cannot go into fridge compartment. Thus your freezer works good but not fridge compartment. Milk goes bad but frozen meet keeps good.....
Vent freeze up either due to defrost problemt, defrost drain line problem, Evaporator fan problem or even can be your damper motor not opening due to unit failure or frozen damper door.
It sounds as if the freezer coils and vent stack are frozen solid. This usually requires removing the back panel in the freezer compartment and defrosting carefully with a hair dryer. (If this becomes frozen it blocks off the fan/vent that feeds cold air down to the fresh food compartment) Make sure to unplug unit before servicing as you will need to unplug the fan to remove the back panel. While doing this check the defrost termination thermostat (a small device attached to the tube with two wires coming out of it). The black plastic ones sometimes come apart and fail. Once defrosted put everything back together and test. Hope this helps.
remove the rear cover inside the freezer if it has a lot of frost on it,then the evaporator coil is frozen up and you cant blow cold air over or thru a solid block of ice,defrost it,then check the defrost heating element,defrost thermostat and timer or defrost circuitry for no power or defective components,you can use a hand held hair dryer to defrost it quicker
your evaporator coil in the rear area behind the freezer back panel is frozen over with ice and the coil can no longer deliver cold air due to ice blocking the air flow from the evaporator fan,remove this rear panel,defrost it with a hair dryer,check the defrost heating coil for continuity,they go bad regularly,if not the heater coil under the evaporator coil,it may be the defrost timer in the refrigerator section of the unit that powers the defrost coil that needs replacement
Nine out of ten times it turns out to be a defrost issue. What most people dont understand is the refrigerator gets its cool air from the freezer. If the evaporator coil in the freezer becomes a block of ice then the airflow from freezer to fridge section is blocked. The block of ice along with already frozen foods in the freezer compartment help to keep those foods frozen. Therefore you assume the freezer section is fine. However, the lack of cool airflow to the fridge side quickly turns that 38 degree air into 50 degree air. You could try unplugging the fridge and leaving doors open for 24 hours, this will thatw the evap coil. Plug it back in after the 24 hours, and within 12-24 hrs everything should be cool. If the fridge continutes to cool for about 3-6 days and then fails again, you certainly have a defrost problem. This is long winded, but hope it helps
two options...one drain hole blocked in freezer,clean with copper wire/bleach to clear gunge.
two outside temp too cold i.e. unit in garage/outhouse( too cold for compressor )
also check seal to doors.air leaks...
there is a fan in the back of the freezer that pushes air into the fridge side of the fridge it sounds like this has gone out on you. this fan is usually right by the coils in the freezer the only thing that keeps the fridge cold is a little air being pushed over there constantly
Check to see if there is frost on the freezer back panel if this is a side by side. Could be the air vent is blocked by a frozen pack of vegetables or something else. It could be your freezer coils are frozen if this happened and you will have to take the freezer panel off and with a hair drier defrost them completely. Hope this helps.... Woody
It sounds like cold air from the freezer isn't making it to the fridge compartment. This can be cause by a several things. The damper that lets air into the fresh food side is stuck in "closed" position, the temp sensor (t-stat) isn't working properly, the evaporator fan (in the freezer comp above the coils) isn't working to blow air up to the fresh food section. In some situations, the defrost cycle for the freezer section isn't working and the coils have frozen into a block of ice and air can't flow over them properly so you get not cold air to the fresh food section but the freezer still stays cold due to the block of ice.
Ahhhh, the classic symptom of a frozen coil/air return duct. You'll have to pull the back panel off the freezer wall to view the coils. The are likely a block of ice causing the air channels on the sides to be frozen, thus blocking air flow. You may need a defrost t-stat or a defrost timer. If the defrost cycle isn't working then you will get a freeze up eventually. The only other reason is if the freezer door was left open slightly overnight letting in moist air. Let us know what you find.
