Door ajar alarm ringing and refridgerator not cooling enough
Christmas Eve, 20 people over and the refridgerator decides to not work. Door ajar alarm continuously beeping, inside light off and refridgerator not cooling enough. Day after Christmas, empty and turn off refridgerator into cooler. Unplug to reset thermostat for 10 minutes, replug...still does not work. Unplug and defrost freezer for one hour reset and wait. Freezer to desired temp of -4...but fridge is 67 degrees. Beer is still cold amazingly but food warm. Is this Samsung refridgerator worth fixing? Hardly no-one fixes Samsung for some reason. Begged one repair specialist to travel. Should I toss or save??? Is 5 years old.

Re: door ajar alarm ringing and refridgerator not cooling...
This could be a defective thermistor telling the fridge that the evaporator fan is frozen up with ice. But if you are lucky like me it is a defective door switch, telling the fridge that the door is open when in fact it is closed. The fan sending cold air from the freezer section to the refrigerator section turns off when the door is open, so a defective door switch can keep that fan turned off all the time. Push the buttons on the door switch to see if the lights go off in the freezer and refrigerator. If not, use a knife or screwdriver to pry out the switch and unplug it. Then you should hear the fan turn on, and the refrigerator start cooling. Good luck! genetuck PS....my light was not coming on at all, and I had to unplug the refrigerator for five minutes, then plug it in to get the light to work. I just discovered the switch was defective, and don't know yet if there will be any future problems with the light.

There is no reset for the alarm. The alarm goes off when you are not maintaining temperature.
During the time the door was ajar, warm air got into the freezer either icing up and locking the cooling fan or forming a block of ice on the cooling coils (Restricting cooling air flow.)
The best thing you can do, unless you want a $300.00 plus service call to defrost everything, is to turn power off to the freezer. Open the freezer door. Have plenty of old towels to soak up the water in the bottom of the freezer as it defrost.
You did not provide a model number which is located on the inside wall of the freezer. Every 8-10 hours your freezer will completely shout down for 20-30 minutes where only the light works and the defrost heater turns on. The ice build up is too much for the defrost heater to handle.
In some freezers the defrost mode is in the control board, in others it is a separate component that you can repeat trip using a flat head screw drive.
Its a thick pin surrounded by a rubber ring/bellows that is in the doorframe of each door. Each pin operates a switch. When the door closes it presses the pin in and when it opens the pin slides out so it protrudes into the door frame. Open each door one at a time and press in the pin with something strong like a shoe heel, this simulates that door being closed. Do it several times, till you find which switch is not working all the time. Change that switch by removing the rubber surround and unscrewing its fasteners.
To all you Acura alarm sufferers. In the immediate term to appease your neighbors - open the door and reclose, leaving the door ajar enough that the interior door light is still on. Be sure to turn off the roof light so no one is cued your car door is ajar.
When you can go under the hood, remove the fuse - I think it is 15 - the fuse box cover has a diagram. I left the fuse out for a couple of hours and reinserted it. That broke the pattern for 7 months.
It is 89 degrees in chicago today, the alarm went off at the train station and I got a ticket for noise disturbance. It's time to look at the fuse box again. i think extreme temps are the problem.
this unit has a history of the light circuit failing and it will cause the lights to either stay on or off. if they stay on, it will melt the housing around the upper bulb area. it has a recall and should be covered by sears for no charge. it is the control board failure and has a sticking relay for the light circuit, needs board replaced. the 3 beeps are the unit thinking it has a door open. turn off the alarm on the door control board and call sears 800 # for repair.
If the door was left ajar for any extended period frost has built up on the cooling coils. A complete defrost of the freezer should take care of the problem. Normally a frost free system will clear the ice from the cooling coil when the defrost time cycle happens. However frost may have built up in areas where the heaters can not readily remove it in a normal defrost cycle and shutting the unit down with the door open for about 24 hours should clear it out.
