    my frig is a frost free freezer at bottom I purchased it I believe in 2006 or 2007. Could I use a blow dryer to get rid of the snow?

    1st make sure it's a self defrosting freezer / refrig. is it clear solid ice or frost snowy ice? clear solid ice is usually an indication of a clogged drain and one of the most common causes of ice build up in a freezer. frost or snow is usually an indication of either a bad seal (moisture entering the freezer ) or can also be low on freon. let me know how the ice looks and i can suggest your next steps to repair

The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others.

Frost buildup at back of bottom freezer department. Refrigerator should be frost free. Freezing impaired.


could be anumber of things happing, is the freezer fan spinning? if not ice will accumulate( also hamper cooling in the refrig section). perhaps a defrost issue, a bad heater or defrost thermostat could also cause, this/ may even just be the door being left open for extendedperiods of time( ie.. overnight, or hte gasket not sealing correctly) leading to a frost build up on rear panel

Generally speaking if the refrigerator does not cool and you have frost on the back wall of the freezer it suggests a defrost problem.
However since the refrigerator started working by itself it would point to an air circulation problem from the fan in the freezer compartment failing to operate. The frost on the back wall without the fan operating would cause frost buildup because the heat is still trying to get to the coil through the back wall. If your refrigerator freezer has a door fan light switch something holding the door partly open would cause the fan not to operate. Look for a button or toggle and manually push it in. You should hear the fan turn on and the light will go off.
