I have a true tuc48-f freezer..Problem: Frost build up to the point that the doors freeze shut and I have to scrape the ice off. Also at time it make a rackety noise like the fan hit solid ice.

Frost free means that the evaporator coil will not accumulate a thick layer of frost. It will not prevent frost from accumulating on the walls of the freezer. To slow down the amount of frost build up inside the freezer, do not keep the freezer door open for any longer than necessary. The freezer door seal may be defective. This would allow moisture in that would freeze on the inside walls. A heater with timed intervals to come on is one way for a frost free feature. But this will not work for frost build up on the inside walls of the freezer. It would only melt the frost and then it would refreeze again.

check the door seal on the top of the door if not sitting flat to the frame it will encourage frost to build up (inside the little grid thing)which will stop the rest of the freezer from cooling enough.

Use a turkey baster filled with very hot water and flush it several times. That should resolve the problem. Also check the door gasket, if it is leaking, excessive frost would be visible causing more water then the system was designed to handle.
Good Luck,

is this a chest freezer? Thick frost around top? try defrosting unit. DO NOT scrape the ice. Very important to remove drain plug to remove water or frost will very rapidly redeposit

You should to check the Whirlpool Gladiator Freezerator's door sealer to make sure all rubber or plastic seal very well to prevent air humidity come in to build up frost fast. Also, you have to defrost completely and wipe with cloth or paper towel to absorb all waters out and let it dry completely to prevent frost build up.

defrost drain may be plugged.shut freezer off,melt ice with blowdryer,and unplug drain.drain probably located behind inner back wall beneath coils.

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.

Hi, You will find that your problem relates to the defrost heater in the freezer. You will need to take the drawers out and remove the back panel to access the evaporator. There is a foil heater that lays underneath the evaporator and it will need to be changed. Along with the klixon that controls it. This will ensure that both parts are good. Your problem will then be fixed no more water!
Good luck................

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;

ok promblem 1 raise th front levelingm legs so that when the door is released from opening 1/3 of the way it shuts its self promblem 2 if the ice gets so thick it blocks the air intake of the freezer it cant cool your defrost drain is blocked its under the back panel in the freezer and needs to be cleared
