Freezer won't reached desired temp or make ice

As far as your freezer frosting up, sounds like a door seal problem, run your fingers along the seam of the door seal, there should be no splits/holes in the seal.
As far as the refrigerator either there is a secondary fan motor, or there is a obstruction blocking the air movement, if the freezer has a bad seal, its suspect ice is still building up.

The fridge depends on the freezer for cold. Now that winter is coming, the mice are playing. Pull the cover off the tubes in the back and make sure there are absolutely no openings in the back of the freezer. Mice like to travel up the tubes and chew away at the styrofoam where the tubes go into the freezer. Sometimes, they also get into the freezer and block the drain opening. When this happens, the freezer becomes ice-bound and the cold air won't circulate until the ice and dead mouse are removed. To see the drain, you will have to remove the inside walls in your freezer.

ice cream is always the last to freeze and a temp of minus -10 degrees is usually required to get it to get hard. if you put the ice cream in the door it will be especially tough to freeze. a good thermometor is a good investment as you can observe the temps. usually ten degrees or 20 degrees is what they run. yes they do cycle on and off as long as they hold temps thats good. the outside of the freezer gets warm because the hot compressed refrigerant is spread through piping near its surface giving up its heat of compression . setting the stat to max will freeze the ice cream eventually but utility bill suffers . good luck

this alarm is activate if the temp. of the fridge rises and because the freezer section is full of ice form thats why affect the circulation of cold air. try to check the defrost timer if yuor unit have or heater if working if dont have defrost timer or heater try to lessen the setting of your themostat to cut of unit after reaching desired temp. or conduct weekly defrost manually.

The Unit has a defrost cycle either every six,tweelve,or twentyfour hours.It sounds like the thermal cut out is faulty located in the freezer side behind the wall where the fan is situated It is usually a steel round disk shaped sensor with two wires coming out of it.It,s purpose is to shut the power off to the defrosting element once it reaches the desired temperature to melt the ice away and them the unit cycles again after defrosting.Hope this helps.

water supply must be checked first, constant flow to the area confirmed. compreesor running? does the system reach temp in other compartments? Isolate system from the electrical supply pull away from the wall and clean behined unit clean coils and fan blades.
check tube for water still connected and return unit power supply. let me know what you have temp in fridge and freezer if this unit is duo.

remove freezer back panel and you will see a tray at the bottom with a drain hole in the middle and it is this which is blocked. if blocked with ice, clear with some hot water and make sure drain is free and water flows away

The red warning light will not go out?

1. Has the fridge freezer just been
installed? If so, this is normal and the
light will go out when the correct
temperature has been reached.

2. Has the fridge freezer been loaded
with a large quantity of food? If so,
the light will go out when the correct
temperature has been reached.

3. Have the doors been closed
properly?

Our 550 bottom freezer drawer froze shut earlier this week and the motor made an unusual sound, like it was working too hard. Two of us eventually were able to open the drawer to find that it had frozen shut due to a leak which filled the ice tray solid and then adhered to the actual door, freezing it shut. We emptied the fridge and freezer, turned the control dials down to 0, but neither the motor nor the light would go off. We finally killed the circuit breaker to get the appliance to shut down. It's cleaned and defrosted and we noticed that the gasket has torn in three places, two on the fridge door and one on the freezer door. The freezer door could be from our tugging, but the refrigerator door is normal wear and tear. We filled the tears with some kind of putty and when it is dry we will start everything up again. This is not the first problem of this nature we have experienced with our subzero 550, but it is the most dramatic. Each previous time we have called a repair man out and he has been unable to fix it.
