AT TIMES The fan usually stops working due to ice obstruction when the defrost terminator has gone out and u get ice build up? u can check the terminator with a multi meter for continuity but do not check at room temperature. stick the terminator in cup of ice water for 20 minutes then check it for continuity, should be closed when cold and open at room temperature.
May also need to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.
Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..

Another item to check with a meter is the heating element itself. Located under the evaporator coils. It should show continuity or resistance OHMS WHEN TESTED AT BOTH ENDS OF THE PRONGS .

Lastly check the cold control thermostat with a meter for both OHMS and volts ( VOLTS is a live test with fridge plugged in so be careful) It must show 110 volts. An open or thermostat that reads infinity will not allow the proper cooling and defrosting cycles to operate and may in fact stop anything from happening as if there is no power to the unit?

ALSO CHECK THE AIR FLOW VENT SYSTEM and THERMISTORS At times it can get stuck to far closed or open. Some units feature a digital electric adjusting vent system while others are manually set. Check for any ice build up or other obstruction in the vent damper, see if u can manually open or close it. Some times when u have the settings set to the highest it closes off one area while allowing to much cold air flow to the other area!
THERMISTORS in the freezer and fridge section for continuity OHMS and for amount of OHMS current being put out. In most models around 13000 ( give or take 150 ohms) ohms is required

SOURCE: the refrigerator is not cooling. freezer still

The fan is probably hitting ice, which did not defrost. Most likely culprit is the defrost timer. This will build up and prevent cold air from circulating from the freezer to the refrigerator. You can remove the rear panel in the freezer, expose the ice, melt it with a blow dryer(careful not to electrocute yourself) and replace the panel. If it occurs again within a week, then the defrost timer is either bad, the fuses to the timer need replacing or the thermostat is not telling the timer when to turn on.

My whirlpool side by side refrigerator just started making this loud noise that sounds like either what an air compressor would sound like or a lawnmower. The model is ED5FHE


There are two fans running on a side by side, one is behind the back freezer panel on the side of the freezer side( if it is iced up the fan blade could be hitting ice) May be a defrost problem......
(this fan circulates air from the freezer side to the refrigerator side, as the air is pulled through the coils heat is removed)

The second fan is in the back, you have to pull out unit and remove lower back panel to listen and or look to see if condenser cooling fan is running quiet or the compressor right next to it. Could be this fan blade is hitting something or a bearing going out.......

If the compressor is making the noise you are probably not going to repair it.....

Lastly on some there is a defrost timer motor usually found by the thermostat but not always that could be making noise(least likely) May have a adaptive defrost control board, not sure.....

Hope this helps........

The bearings are going bad on the fan motor and that lets the blades move too much and they hit...you will need to replace the fan motor.

Top section not working


If there is a lot of frost build up on the back wall of the freezer section you are having a defrost problem and the coils behind that wall are filling up with ice restricting air flow and letting fan blades hit it. If not a lot of frost the evap fan motor is going bad which is also located behind the freezer wall. Good luck.

Loud buzzing noise coming from the freezer motor like something is stuck or hitting...possibly a fan...possibly the compressor...


Sounds like pipe vibration, you will need to take a cover off if there is one to get to the compressor. Check to make sure no pipes are rubbing against each other first, you can bend them apart carefullt, watch out for a hot pipe from the compressor. Also check to see if there is a cooling fan for the compressor, make sure all fittings are tight etc, If the noise is still there call a refrigeration technician.

My 10 year old amana fridge makes a noise from the fan in the freezer it sounds like something is hitting it ,but on inspection I see nothing hitting it


Look closer because ice can build up and the fan just barely hits it making the noise. If the fan blades are not hitting anything, replace the fan motor as the bearings are getting worn out.

Maytag admiral refrigerator, the fan inside the refrigerator is making a loud sound when on and the cooling in the refrigerator is freezing


Makes sense, you are not moving enough air. Do not over fill the refrigerator. Fix the problem with the fan, if it is noisy I am 99% sure it is not moving enough air. To make noise something mechanical is hitting, it could be either the fan blade (cheaper to fix) or the motor.
Good Luck,

LG Fridge making intermittent sound - like something hitting fan


GAIN ACCESS TO THE FAN IN THE FREEZER(EASIER SAID THAN DONE) AND INSPECT THE FAN BLADE AND FAN SHROUD. HAVE REFRIGERATOR TURNED OFF AND MANUALLY ADVANCE FAN BLADE. WATCH FOR SLIGHT CONTACT BETWEEN THE FAN BLADE AND OTHER OBJECTS NEAR IT-ELECTRICAL WIRING, FAN SHROUD, ICE CYCLE,ETC. ADJUST FAN BLADE OR OBJECT TO INCREASE CLEARANCE.
