I have a small Chefmate fridge that I got at the beginning of college and has since stopped working. It stopped blowing out cold air and instead blows out air at room temperature, keeping anything inside the fridge from getting cold. Any help?
The Chefmate 1.7 fridge uses a thermalelectric device (TED) to provide cold air. There are no moving parts there. The problem is usually in the power supply. That is the PCB on the left side behind the back cover. If the fans are running then your thermostat is bad or the TED is cracked. You can buy these ebay or other places on line. To change one you must carefully remove the large heat sink. The TED itself is only about two inches square. If you decide to replace this unit be sure to get a supply of heat sink glue. Otherwise you will end up with a hot (or cold) spot on the TED possitly causing another crack.
I fixed my chefmate 1.7 fridge by directly applying 12 volts with a laptop charger to the wires leading to the thermoelectric device. If you keep those wires connected to the circuit board, it will power everything else. however, it seems like your problem is in the thermoelectric device. You can get a replacement at amazon.com for 5 bucks. the part number is TEC1-12706 you can learn how to replace it with this video: http://www.youtube.com/watch?v=KBhVS7GhCOM&feature=related Good Luck!

Re: (1.7 cu) Chefmate Fridge Doesn't Get Cold
For some reason or another the
compressor may not be starting. If you get right down and check it you
may hear what we call "cycling on the overload". This is a click, a
pause, then a pop which repeats every minute or so. This can be caused
by a cooling fan that doesn't work, a relay, or the compressor itself
burnt out. You can check the fan if present by starting it ten times in
a row, (it should start each time). Depending on your situation you
could try a new compressor starter and if that won't do it
you'll know it's the latter case.
If the compressor does in fact run, in the situation you describe,
you have a more serious hermetic system problem. This is something you
have to call a technician in for to get a better idea of the cost for
repairing this one. Hope this helps.

Brand name and model would help but here is a guess. Most frost free refrigerators have the main cooling unit in the freezer area side. To get the fresh food side cold, there is a small fan in the freezer side that blows cold air to the fresh food side through a duct work or trap door. If that fan stops or fails for and reason, the first place you will notice the temp rise is in the fresh food section. See if you can hear the freezer fan running. You may need to push in the door switch for the freezer light to hear the fan because they sometimes run the fan wiring through the door switch. It may stop when door is opened.
There has to be something restricting the air flow to the fridge. If the fan is running blowing cold air into the freezer, then it should be cooling the fridge too. Empty out the fridge and freezer and use a blow drier to blow hot air into the duct work. There could be an ice blockage not visible in the duct work.
try keeping the freezer door shut while felling for cold air blowing over to refrigerator side..if so problem lies in the thermostat...its not sensing the correct temp for the fridge side and closing the damper too early...also check to see if there is frost built up on the back wall of the freezer section if thats the case then you are at the begining stages of a defrost issue and soon no cold air will blow over to fridge side..let me know what you find
if the fridge part is cool and freezer is fine what problem are you having?is the fridge not cold enough? a common problem with bottom mount freezers is the freezer door doesn't get closed all the way,warm air enters the freezer mixes with the zero degree air and freezes up the air ducts,when you open the freezer door you should hear the fan blowing,if it is check the ceiling in the freezer to see if ice is on it,check the packages for frozen water droplets and stick your hand in the fridge where the air ducts are to see if you can feel cold air blowing into the fridge,if you can't feel air blowing into the fridge,unplug it,open the freezer door,remove the top basket and remove all the food out of the bottom basket,with a hair dryer blow into the back wall into the vent holes and melt out all the ice in the ducts,you'll see water dripping down through the vent holes,when the water stops dripping plug it back in and see if the fan is blowing the air into the fridge.also you can remove the bottom kickplate and you should see a tech sheet in it,read it and it will tell you how to put the machine into defrost,it will stay in defrost for like 20 minutes,you can do this instead of unplugging it, there's a heater that comes on behind the back panel in the freezer,this can help you melt out the ice but if it seems to hard to do just unplug it.
The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp. The problem could be the electronic control if you have one or the mechanical linkages.
If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.
check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.
The fan that blows cold air out of the freezer into fridge is not working or the passage is blocked check fridge side wall verify openings from freezer are clear and feel for airflow. I need a specific model # to provide better info.

Either the freezer fan has stopped blowing air or the defrost timer has stopped and the airways to the fridge are clogged with ice. Only the freezer gets cold in a refrigerator. The fridge part gets cold by cold air being blown through air passages from the freezer. Good Luck!!
with thethermostat turned to its coldest setting can you hear or feel the compressor running? Can you find the defrost timer inside the refrigerator and turn it until the compressor stops, and then please let me know, JT
