Frost builds up in the back of the bottom freezer (Amana ARB224RCW refrigerator) We have defrosted it, but the frost builds back up in 2 weeks. We don't think the freezer is overloaded.

is it a frost free model? if it is the defrost timer may be out or the defrost element may be bad. but if this is not a frost free model the door seals may be bad and need replaced

Hello Nicole,

Their are a few things that couldbe causing your refrig.troubles.

1) their is ice build up in the return air vents that is not allowing air to flow correctly
you can see the air vents under the crispers in the ref.floor and can see if they
blocked with ice.

2) the freezer fan is bad and not circulating cold air into and out of the ref.

3) In addation to the defrost timer,perhaps the deforst heater and defrost thermostat are bad and frost is building up in the freezer,Do ya see frost
build up in the freezer??

Really when the fridge frost very excessively there is less cold.
You have to regularly set up defrost setting if your fridge has automatic defrost.
Or your fridge has manual defrost then defrost it twice a week.
To minimize excessive frost, set the temp control setting to just mid- position.
Good luck.

you need to check the defrost circuit and make sure the heater is working and the unit goes into the defrost mode.
also check and make sure the temp sensor is good

the unit is experiencing a defrost issue one of 3 things bi-metal thermostat clipped to the evap.... defrost heater element is now open or very little resistance reading or defrost timer unit you can get fix remove the items in freezer and remove the back panel with hairdryer in hand thaw the frost and unit will oper normal for a time

Sounds like the defrosting system has a faulty timer/board, faulty heating element or bad electrical connections to these components.

More info, let me know...

could be thermostat or defrost heater or defrost timer.you can check the heater with meters that check continuity.the thermostatis located on top coil and sometimes they will seperate.so look for those 2 things.most likely it will be one of the 2.the defrost timer is most likely good,if you hear your machine turn off and back on then the timer is good.

freezer side is working good but cooling side is not cool

Is your fan blowing in the freezer? Frost on the back wall of the freezer usually indicates a defrost problem... defrost themostate, heaters, take back panel off and check evap for frost build up and if your fan in working.
