5 reasons for fridge and/or freezer getting warm: 1- the evaporator coils are icing up and won?t let air circulate. 2- the evaporator fan is not working to circulate air. 3- there is no refrigerant in the system. 4- no power to fridge or compressor. 5- the condenser coils have no air circulation check under the fridge behind the vent. if it is too dusty or the fan isn?t working, it is not getting enough airflow to cool down. replace fan and/or vacuum out the dust. if there is no power to the fridge, the light will be off. if the compressor is not running, there is a defrost timer that cuts the power temporarily to the compressor to melt ice on the coils. it?s located under the fridge behind the bottom vent. If the timer is off and the compressor is not going, the compressor or the main board is bad and needs replacing. there is also a temperature sensor on the evaporator coils that tells the defrost coil to turn on and when to turn off. if the defrost timer is on but the coil is not heating up, replace the sensor. if it still won?t heat up, it?s the timer or the coil. the easiest way to tell if there is no refrigerant- the freezer wall is warm and the compressor is loud. if there is no refrigerant, it may be more cost effective to replace the fridge. if you feel no air coming from the freezer vent, the fan needs replacing. If you feel air moving in the freezer but not the fridge, the channel from freezer to fridge is blocked. if the freezer has air and the rear freezer wall has frost on it, the evaporator coils are iced up and need defrosting. causes: 1. low refrigerant 2. no fan 3. too much humid air in fridge/freezer due to door open or bad door seals 4. the condensate drain tube is clogged if the seal around the door is ripped or not completely sealing, or there is condensation at the bottom or the walls of the fridge, replace the seal(s). no air, no fan. Replace if the refrigerant is low, it just needs a top off. but you need to be certified by the epa to move refrigerant, so get a professional. defrost solutions: unplug the fridge. remove the wall of the freezer that is frosted/icing up. use a hair dryer to melt the ice. do not get too close. you will see a drain under the evaporator coil. make sure it is not blocked. the water should run freely to a condensate pan under the fridge that evaporates the condensation with the hot line from the compressor. once the coil is free of ice, frost, and water, replace the panel and repair any of the problems that caused the icing up. plug the fridge in and turn it on. If it frosts up within a week, there is still an issue that not been taken care of. after the freezer freezes again, your ice maker will work again.

Wake up one morning and Boom no ice left in the bin. What happened and What can I do to fix it without calling someone? Some ice makers will get a piece of ice in the wrong place and jam the extraction. Get a hair dryer and heat up the ice maker to release the fouled ice cube and that baby will start going. No water in ice mold?Do this easy test: pour some water in the ice maker mold and wait. If it kicks out a batch, but it has no water in it, most likely the water valve is bad. Watervalve for SxS box Since it is the cheapest part and you can do it yourself replace it. If it turns out you need a new ice maker then you have a new water valve already to go with it. What if the ice maker has ice in it but won't harvest any? One cheap and easy item for the do it yourselfer to replace is the ice mold thermostat. Check for voltage between T and H if you have 120 volts then the bi-metal (inside that ice mold thermostat) is bad. If it's good you will have 0 volts. Ice mold thermostat Located in the plastic housing and seated against the ice mold is that thermostat. This looks intimidating but is easily fixed by anybody who could change a spark plug. There is no wiring. One more thing to look for: You can put a jumper between L and V and this will activate the watervalve. Have rags ready! If you are a cheapskate and want to be frugal and not buy a new ice maker or a new head(brain) modular crescent ice maker you may want to remove the main gear and clean the copper plate behind it. That plate gets dirty and won't allow for a good contact with the water valve connection and does not power up the valve...Shhh! They will all be doing it! Modular crescent Icemaker test points: With NO power to the icemaker, and ice ejection fingers in the freeze position: Your ohm meter should read 8800 ohms between L and M, and 72 ohms between L and H. With power ON to the ice maker: If meter reads 0 volts between L and N you have no power to the ice maker. If the meter reads 120 volts then you have power to the ice maker. If you have 0 volts between L and H heater is off if you have 120 between L and H the heater should be ON. If you have 0 power between L and M the motor is off. If you have 120 between L and M then the motor should be ON. If you have 0 volts between T and H the thermostat is closed If the meter reads 120 between T and H then the thermostat is OPEN. If the voltage is 0 between N and V the water valve is closed. If the meter reads 120 water should be filling the mold.

SOURCE: ice maker quit working
I know this sounds a bit droll, but you say without explanation, do you expect it to talk to you. You will probably find that the timer has packed up. check this out and replace if neccessary.

SOURCE: my ice maker quit making ice.
Hi, If your ice maker has stopped making ice then you need to check these things.
The lever that controls the ice maker has been pushed up which turns it off. If you have a red lever, pull it down to the wire and if you just have a wire then just pull down the wire to start your ice maker up.
Make sure the freezer temperature is below 10 degrees F If the freezer is too warm ice production will be poor because the ice maker will not cycle properly.
The ice maker fill tube may have ice formed in it, blocking it. Use a hair dryer to melt the ice. Watch out for the plastic parts, so that you do not melt the plastic. Also check the water inlet valve and the shut off valve, to make sure it is not plugged with debris. The openings in those valves are very small.
Check the gears in the ice makers to see if they are broken or stripped. Also look to see if the ice rake is broken. All parts in the ice maker are replaceable individually, If you find broken parts replace them.
