Re: 2 yeaor old kenmore fridge not working, motor runs
As the weather is getting warmer for many people their freezer and/or refrigerator do not work right because of a dirty condenser coil...
Check out this tip that I wrote about that... it is a great place to start trouble shooting your unit...and something that you can do rather then calling a repair person to do a simple thing for you...

Check to see if the cold air supply from the freezer to the fridge section is blocked and that the fan is running. The fridge uses cold air from the freezer to cool and many times the intake is blocked by something in the freezer compartment.
check the fan that runs from the freezer to the fridge that it is running and not blocked or stuck if needed service the fan or replace if not repairable---if fan good than check fan duct that damper is operating properly the fridge uses the air from the freezer to cool it down
This is what has happened. Due to the door being opened for so long moisture which is naturally in the air has collected on your freezer coils. What you need to do is turn the whole thing off for at least 24 hours. Open the doors and put some towels around it to let the frost melt out. All the air that gets cooled in your unit gets cooled by a fan that pulls air through those coils. Once the frost has melted out of them it should cool just fine.
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 . 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. You

The evaporator fan motor may be about to seize and is running to slowly to cool the fridge, cost about ($30).
Check to be sure you can get a replacement fan first, they last about 4 - 5
years. Available from a parts supplier or electric motor company.
Unplug fridge. Located usually in top of freezer behind a vented cover
plate. Remove cover, remove screws holding fan in, may have to cut
Replace with new motor, make sure the fan spins the same direction (CW
OR CCW) as your old one, if you don't know which way it should spin
then be sure it pushes air into the freezer area and
doesn't spin backward drawing air from the freezer area.
Most times this is a bad cold control, but there are other things to check for. Make sure the condenser fan is working and the coils are not covered with dust. A separated heat exchanger ( small capillary tubing soldered to the large suction line ) can separate from one another and make the fridge run too long. - tape tubing back together. A poor working evaporator fan motor could also make the fridge run too long and freeze - replace the fan motor. An inefficient compressor or refrigeration system could make the fridge run too long and freeze - have a service tech check this out. A misaligned control settings, make sure the air damper and cold control have not been bumped and are out of normal settings. Stuck open air diffusers or air dampers are becoming more and more common for allowing too much air to be blown into the fresh food section and freezing things. On all frost free fridge's the freezer temp air is blown into the fresh food section, if you have "easy" to freeze items ( eggs, veggies in water, etc ) in front of or under where the freezer temp air comes out, they could freeze - store them in a different spot. Doors not closing properly making the fridge run too long is something else to check for.

Listen for the fan motor to run. Open the freezer\ push the door switch with your finger \ listen for the fan that blows the cold air to the fridge. only the freezer side gets cold...fan blows cold to the fridge side. If the defrost timer has broken then ice may be blocking the flow of cold air to the fridge also. Only 2 things to check. Good Luck
I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........
In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.
Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.
Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)
Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.
