Question about Kenmore 73502 / 73504 / 73509 Bottom Freezer Refrigerator
Hi, There are several reasons this can be happening...
1. The seal on the door may have a tear or may not be seating properly...this allows excess warm air into the freezer compartment and in its effort to remove the same ...frost appears.
2. There is something call a thermistor that is cycled on and off as needed to remove excess frost accumulation and or ice buildup on the evaporator (freezer) coils...it is a heat strip which actually defrost the frost/ice. if this is not working frost will accumulate and eventually it will become Ice......now the remarkable thing about Ice accumulation is that you would think everything would remain cold or get colder ..however in this case the opposite occurs...it insulates the coils and thereby increasing the temperature...put a thermometer...one that is calibrated properly...(calibration can be set by placing a thermometer into a glass of ice water...the temp of a glass of ice water..after a few minutes setting will be exactly 32 degrees)..if the temperature of your refrigerator is gradually rising over the period of a week...you will need to call a tech or replace the thermistor and or trouble shoot other problems that can occur such as..
3. The evaporator fan may be going out although they usually make a high pitched whining noise of a whirring noise before they go out...not always and if they are intermittently cycling off then frost would build up...do you always here a fan running when you open the freezer...if so that is good...fan is working...but it may be cycling off at times when no one is aware.
P.S. the odds of your ice maker causing this are very, very slim..
