Frost in the freezer

your freeze have cooling matchine problem.

Change the defrost timer.

if the doors shut okay,and there is no frost,and it is maintaining a steady internal temp(-18C to -20C) why worry.......anything else is going to cost money.......

the coldest part of a freezer gets frosted up the fastest( i cannot believe you are running a freezer with no door !!!!) like running a/c with doors open
just replace the seals asap.

the auto defrost fan is drawing the air out to cut down on frost buildup....when you do put food in freezer use vacuum sealer to stop freezer burn and keep portions seperate,easier to rotate food for consumption.also frozen meat can be kept for upto a year at minus 18/20c

2 months old should still be under warenty.

Check the freezer fan by opening the freezer door and pressing the door switch and listing for the freezer fan sound. If no sound then the fan motor could be bad.

Look at the back wall too see if you have frost build up. If you do then you have a defrost problem.

If thees are not your problem you could have a seal system problem. (( freon leak ))

if it a frost free freezer then chances are it is a defrost hearter, fan motor or defrost timer
if it is not frost free then it will either be the compressor or a gas leak ( which should be under warranty)

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.

That you have to 2 defrost your freezer it's normal depending of many factors. Do you open it often, is it in a warm place, is the food that you are putting in it is warm? many factors contribute of building up frost faster.

7 minutes on and 15 minutes off sounds like a good cycle time.
