I kind of doubt that the fan is the problem. On my refrigerator, when it goes on defrost, the fan shuts off. They don't want it blowing heated air on the milk. Yours might be different.

I don't know this particular frig, but evidently the defroster doesn't work. Perhaps the fan doesn't work also, or perhaps the fan would work if the defroster were fixed.

There is a defrost timer, under the frig, accessible from the front. You can turn it with a screw driver. Turn it till you hear a click. If the timer hasn't been turning, that should turn on the defroster, a heating element nested among the freezer coils. Wait half an hour and if it is defrosting, water should be dripping into the drip pan underneath the frig. If so, then replace the defrost timer and you're good to go.

If that doesn't make it defrost, then the problem is probably the defrost thermostat, in with the freezer coils. When the frig defrosts, the defrost heater stays on until the defrost thermostat gets warm. It should be open circuit while warm. But if it is open circuit while cold, it is bad and is the cause of your defrost problem.

If you open up the freezer coils, use a hair dryer to defrost. That is safer than hot water.

I think that when the defrost heater is turned on, then the fan is likewise turned off. The defrost thermostat, I think, is doing it's job, letting it cool again. But the timer is stuck. Or something???.

Hope you can fix it.

Fan in freezer has stopped working,have defrosted and fridge seems to be cooler.


Simply defrosting the freezer might solve your problem. Sometimes ice can form on the fan or fan motor, and of course, prevents the fan from turning.

If there is ice here, your refrigerator isn't defrosting properly. This sounds like a defrost problem that may need a part replaced. Check out this site for details and photos. Refrigerator Defrost Parts

Fridge warm, freezer has frost on back panel & is defrosting, fans work, just changed defrost thermostat, no air is moving from freezer side to fridge side, drain pan under fridge is dry


this fan needs to run when the compressor runs,check fan blade for being jammed by ice if you have this much ice on back wall as ice will stall motor,if no fan there will be no cool air to refrige compartment also the defrost drain tray will fill with water then freeze over which in turn floods the freezer floor and refrige compartments cause it cannot drain to the pan in the bottom

. kenmore side by side blows warm air, after


Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay. The relay is a small usually black cube shaped electrical part plugged into the compressor or wired to it nearby. It may appear burnt or rattle when shaken if it's bad. The two connections should show continuity with an amp meter. If it's good then it's most likely the compressor causing the problem.
Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm





Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).
If it's iced up really heavy you have an auto defrost problem. Melt the ice with a hairdryer and check the defrost system.

Tempreture on fridge too high ice build up in fridge mahes noise like a tractor


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.

Fisher and Paykel N500B fridge freezer. Freezer not freezing


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.
