Hi, I have an American style whirlpool fridge freezer about14 years old, in the last couple of months it needs defrosting every 10 to 14 days. was unsure if it may be door seals or something more serious.

hi, is the frost concentrated strictly on the freezer panel or all over the freezer ? including the food itself? thx randy

First tell is changes noise and fan running a lot of the time and frost round the ice maker and sometimes on floor of freezer. When I remove panels freezer panel full of ice.

hi , that is not going to be a door seal issue .if the frosting is mostly on the rear panel ,thgat is a defrost issue ,the model number does not come up . the defrost heater and defrost thermostats can be checked with a meter for continuity, the heater is on the coil that is frosted ,and the thermostat is the small bulb attached to one of the lines of the coil , if one of those parts is open ,then that coil overfrosts and blocks airflow and starts affecting the cooling

Thanks I will check both. could the small outlet valve at the bottom of the drain tube be an issue? have read that some can fail but mine just covers half the tube so unsure how this could fail.

if the drain frosts over ,its more of a hard ice buildup just on the floor of the freezer , you can test that by pouring hot water on that drain trough and insure it drains propely
