Tip

My refrigerator is running but not cold enough....


My fridge is running but not cold enough: Start out with the easy stuff first...make sure the lights go out when you close the door(s), make sure the doors are closing properly and the gaskets are closing fully and not torn. Check to make sure the evaporator fan in the freezer is working, this fan blows the cold air around. If the fan is not working, possible bad fan motor - check for power to the fan motor and also check the fan switches around the door openings, ( if your fridge has these switches, not all do ). A common problem cropping up in the last several years has been the air damper not opening up and allowing the cold air from the freezer to be blown into the fresh food section ( mostly on SxS refrigerators ). For many years the air damper was manually operated and now we have motorized controlled or temperature controlled or thermister and electronic boards controlling air dampers, and if this device sticks closed the FF section will normally warm up. An example picture of "one" style and an air damper ( called a diffuser by Whirlpool ). Next would be to check the condenser tubing, a good place to start is to make sure the condenser coils are not built up with dust!! Make sure the condenser fan motor is also working properly. Check for any "clicking on and off" noises from the compressor, is the compressor running.

The most common fridge "not cooling" problem is a frost free failure. Remove the access panel in the freezer section to expose the evaporator coils. If the coils in the freezer section get plugged up with frost, this frost will block the evaporator fan motor from blowing the cold air around. The fan blade can also hit this frost and either become noisy or stop altogether. Locating the defrost timer can be tricky....they are often hidden behind the back bottom corners of the fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some behind the cold control cover. Once you locate the defrost timer, slowly turn the screw like wheel in the middle of the defrost timer with a straight screwdriver until the fridge shuts off. You are now in defrost. If the defrost heater(s) comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not come on, you can ohm test the defrost heater for continuity or volt test for 120 volts to the heater(s). If you have no power to the defrost heater(s) you can also bypass the defrost thermostat to see if the defrost heater will come on, join the 2 wires together to bypass the defrost thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat. If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater* and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.

Makes a loud noise when doors are shut but shuts off when door is open


Hi,


Thank you for contacting fixya.com.

Check the door gasket or the hinge those can get loose. When the door is opened and closed you change the air pressure in the fridge/freezer so you may have a leak in the gasket. You also change the air pressure to the evaporator fan which supplies air from the freezer to the refrigerator so you may have a bad evaporator fan motor.


Please get back to us if you have further query else please accept the suggestion.

The fan has a limit control wired in series that shuts the fan down until the coil temperature reaches 25*F. this prevents the fan from blowing warm around after defrost.
There is also a switch which is placed for the door to close. Either one may be defective.
Worst case is the freezer is not pulling down temperature wise.

Howling noise from freezer fan, GE side-by-side


Replace the fan, Remove the evaporator cover in the back of freezer, and probably another cover for the fan. Unplug your refer first. Usually their are two screws holding the fan bracket to the wall or mount. disconnect the wires, and replace. Their is a newer model evap fan motor that does not have wiring terminals to disconnect, it is hard wired together and you have to practically remove everything in the freezer compartment to get at it. You have to cut wiring and splice the new fan motor in. Fairly tough job. Usually an evaporator fan motor bearing fails from the refer being moved or in storage for a few days at least with the doors closed and the unit unplugged. This allows all that moisture that was in the freezer to get into the metal parts of the fan motor and cause this problem. To prevent this always block the doors open if your refer is going to be off for a few days. This will allow the unit to dry out without damage. Sometimes it was just a bad motor from the factory. Good Luck, Appliance Specialists

You have two fans and a compressor which could be making the noise. Inside the freezer behind the back cover is the evaporator fan. It probably stops running when you open the door. Hold the door switch down to keep the fan running to see if it's making the noise.
the compressor and other fan is under the unit accessed from the back behind the cardboard cover.

Freezer making a loud noise.


Sounds as if the evaporator fan has shaft play or the blades are out of balance or striking something. When you open the door the pressure is equal but with the door closed the fan needs to push the air through the evaporator and return again and circle through fan again. I think soon would be a good time to unplug the refrigerator and remove the back panel covering the evaporator and fan motor to inspect the fan, shaft play and the evaporator for frost buildup or any obstruction of air flow. Thanks, sea Breeze

Freezer section evaporator fan motor bearing are going out. This would be indicted by a high pitched squealing noise. Have the fan motor replaced and it should solve your problem.
