Build up of ice on bottom of freez

A frost free fridge or freezer has a heating panel that is switched on for a short time at the end of each cooling cycle to melt any frost that has formed over the evaporator.
The resulting water droplets are channeled through a drain to be collected in a tray mounted on the motor where the heat from the motor will evaporate it.

The drain of your freezer is probably blocked and has caused an ice build up. You will probably have to at least partially thaw and de-ice in order to find the drain and clear it. This is especially difficult as cold plastic is very brittle and easily broken. Great care is needed when clearing the drain as it is possible to dislodge the drain tube and if unnoticed it will saturate the insulation and render the freezer inefficient at best...

First look at back wall of freezer toward the bottom and see if you have frost build up on the wall. If you do the problem is most likely the defrost heater and you will need to remove back wall of freezer, melt the ice from the coils and then change the heater at the bottom of the evap. coils.

You have bad defrost heater. Remove the back wall of the freezer and use ahir dryer to melt all of the ice from the coils. Replace the heater that is at the bottom of the coils and you will be good to go. Should be able to get the heater from any appliance parts store. Melting the ice off the evaporators will buy you about 5 days of cooling which should give plenty of time to get the heater changed. Good luck and hope this helps.

I think I can assume the freezer isn't a "frost-free".
A short physics lesson; hot air holds more moisture than cold air; hot air will flow from a warm area to a colder area, and the colder area will cause the moisture to condensate and freeze(if colder area below freezing, as a freezer should be), causing frost build up.The more often the freezer is opened, the more frost will build up.
Now for 3 possibilities:1) If it is a self-defrosting type, check your defrost timer control...not working, or not working often enough.2) Door seals damaged and need replacement.3)Make the kids stay out of freezer.

poss answer is drain hole/vent blocked,as unit auto defrosts water/vapour collects at bottom and when unit swiches back on it freezes,poke out drain with thin wire with a small piece of cloth dipped in clorine bleach or blow out with air hose.do not use hot water to manually defrost/ clean drain holes every 6 months

if u have frost build up in the freezer it will affect the temperature
and it needs to defrost
problems could be
defrost timer.
thermostat.
terminator.
heater s.
unit problems (unlikely) if even frost coating.

There is a cheap repair manual for this model listed on eBay. The item number is 200262539606.

hi. thanks for the question. the drain tube that goes down to the drain tray is clogged. turn fridge off .pull fridge from wall. remove back panel clean all coils. let it thaw with doors open, it will thaw quiker. when thawed, clean the drain tube. this will solve the problem. thanks the appliance doc

Hello Scott, remove the food from the freezer side and remove the rear freezer panel. You will see a coil and it should be completely frosted over. If not then you have a sealed system issue. If it is froze solid in frost where you cannot even see the coil, then you have a defrost issue. You should have a little frost on all the coil, the defrost is what clears the frost so the evap fan motor can circulate the air thru out the unit. If frost is good, push the light door switch to start the fan. If it isn't running check for 120 volts. If it has voltage, but not running, replace the motor. Hope this helps.

Your frost free is not defrosting properly. There should be no ice buildup in the freezer section. Frost in the freezer section stops air circulation to the refrigerator section.
