You have a defrost problem. The coils freeze up behind the freezer wall and the air does not flow properly. Replace the heater, defrost timer, and thermostat. get me the model number and i will give you the part numbers so you can order the parts.

    This is caused by either the defrost timer, Heater, Or thermostat failing. The factory says to replace all three at once. This way you will a new defrost circuit and then you will be good to go. I cant give you a reason as to why it happened. There are many reasons why it does happen.

    Go to sears.com and click on the parts icon. Put in your model number and you will be able to pull up diagrams of the unit. You can find the part numbers and where they are located in one shot. You can also order the parts directly from sears also.

I do not believe the problem is the fan. sounds like the frig. is low on Freon this is what will cause the ice build up. you need to find the leak, you can do this by spraying soapy water on coil tubes & watch for bubbles. repair leak & recharge.

Is my defrost timer broken or my thermostat? The freezer was holding -30 temp but now is at +30.


Is the compressor running? If not - the timer could be stuck in defrost mode. If it is ruinning, then the freezer coil should be cold. If it is choked with frost & ice - then the defrost heater isn't getting powered (bad timer or defrost terminator - or is getting powered but has burned out.

You should allow the ice and frost to melt completely before turning back on again. Typically ice and frost don't build up so bad in a few days time to cause the temperature rise you're describing If getting cold - the compressor and refrigerant is likely OK, if not the defrost circuit is suspect. If compressor running but not getting cold - a refrigerant leak / charge level may be causing the problem.

Our Frigidaire frost frost free upright freezer from day one has frost build up on the food inside the packages. The frost is not a problem in the freezer itself, but on the food. Freezer burn occur


Hi Dale Dibb, thank you for your inquiry!

I understand that the food inside of your Frigidaire freezer is getting frost on the inside of the packages. I would recommend turning the temperature up inside of your freezer. Additionally moisture inside of the package would cause frost to develop on the inside of the food packages.

Please assure that all possible moisture has been removed out of the food packages prior to placing the items inside of the freezer. If there is anything else that I can help you with, please feel free to reconnect! -Matt

It sounds like the thermostat is not sensing when the fridge/freezer reaches it's set temperature.This will result in the compressor running non-stop and this causes ice build-up inside the fridge.See on what number (0-7) the thermostat is set on.If it is set on 7,turn it down to 3 and see if it makes a difference.If there is no difference it means that the thermostat is not sensing & switching the compressor off.You will then have to replace the thermostat.

Frost buildup around the inside top of the door of an upright Frigidaire Commerical Frostfree Freezer Mod# FFU20IC8Cw2


This happens when your thermistor gets frozen along with the coils or there is a clogging of the freezer drain which causes Ice to build up and spread to the system. Another issue is that your thermistor may be faulty, telling the system inaccurate temperature. Incorrect freon pressure can also be a cause. I would advise first to have the ice melted by letting the unit stay unplugged and have it cleaned while at it.

My Bosch frostfree fridge freezer keeps icing up!


My Bosch Frost Free Fridge Freezer did the same thing - Ice forming in the bottom of the freezer area after a few days.

It was caused by a blocked drain pipe - When the freezer does the de-frosting cycle, the melted ice drips into a tray and tehn runs into a dish on top of teh compressor, through a pipe.

If this pipe gets blocked, the de frosted ice overflows from the tray and overflows into the bottom of the freezer and then re-freezes !

To fix, pull the freezer away form the wall, locate the pipe that runs to the dish on top of the compressor and blow through it - This should clear it. Alternatively, from inside the freezer compartment, pull off the cover at the back, but the clips holding it on will probably break off, as mine did ! You can sort of push the cover back on and re-fit the food draws.

Thaw's. Turn-off for period of time it would freeze as normal


Make sure nothing is inhibiting air flow. I don't think it is advisable to store food in an ice machine however that is not likely the problem unless the food itself is inhibiting air flow. Most ice machine manufacturers recommend against storing any food in an ice machine. If there is a freezer component in you model the check to see if the evaporator coils are frosting up and the frost is blocking airflow causing the ice storage chamber to get warm. High humidity can cause frosting. Leaving a door to the ice maker open too long can cause frosting. A low refrigerant charge can do this although it seems logically like it should not. With a very slightly low charge one end of the evaporator gets super cold and the other end is not cold enough. Frosts starts collecting on the super cold end and accumulates across the evaporator coil to the other end eventually blocking all air flow. With too much humidity from open doors frost accumulates over the entire evaporator evenly but still blocks. You shut the unit down. It thaws out and works OK on restart until frost again builds up. If its not a frosting problem but it just stops making ice then the ice may not be releasing. Check the water supply and change any filters to insure good water flow. A good water supply is required for proper release and harvest of the ice in many ice machines. If the ice doesn't release it takes a shut down and thaw to clear the suspended ice out. Check for these things and write back if you need further assistance and can provide me with more details.

Ice build-up


Defected DEFROST HEATER can cause frost build up on the panel at the back of the freezer,and freezer stop cooling and ice frozen on unit so air could not flow to refrigerator side.Water will coming out caused of unbalanced freezing,and causing the flooding of water in the floor. You must change this defroster heater assembly so it will works normal again..


Hope this may help;
