Refrigerator temperture is about 60 degrees. freezer 30 degrees and tehre is ice builu up on the back wall of the freezer

Damper stuck closed

Hello;

My name is Peter. I am a retired field service refrigeration technician.

When you removed the freezer you should have seen a even frost pattern across the cooling coils.

If you have ice at the top especially in the upper right have corner, then you either have a restriction or a refrigerant leak. In the upper right hand corner you have a very small tube with a inside diameter the size of a small needle. It is not uncommon on older units for this tube to become plugged up or leak.

A repair of this nature by a service technician would be about $550.00 USD.

If there is ice built up on back inside freezer wall, you have a defrost problem. Either defrost heater, defrost thermostat, or defrost control (timer or Board) is bad.

Check and see if the fan is running in the freezer. If not may be bad or frozen. If is running check and see if there is any frost in the freezer if the fan is in the back then check the back wall of the freezer. If yes the it is not defrosting . Thaw it out for 24 hours and it will work for a week or so but it will need either a defrost timer, heater or thermostat.

my refrigerator goes into auto defrost every 60hrs for 45 minutes or till the bi metal(defrost thermostat) says it had enough....recently i had ice built up on the coil because my defrost thermostat was stuck open...


ice builds up because the moisture that comes from opening the door or food condenses on the cold coil...tempurature of the coil is below 32 degrees which will ice up the condensed moisture...

defrost is timed to remove this build up

the fridge should not be above 40 degrees and the freezer not above 30. check back wall of freezer for frost. if so, coils are iced up and need to be defrosted. either take off back wall of freezer and melt ice with warm water or hair dryer, or unplug unit and let it set with doors open for a day. then clean up the water.

If there is no ice on the back wall of the freezer, make sure the freezer fan motor is running. If there is ice on the back wall of the freezer repair the defrost components. Timer,heater,thermostat.

see if the back wall inside of freezer have ice if so you have to change tiker board or check your doors if closing

Check to see if there is any ice built up on the back wall of the freezer. If so thaw the ice and take the back wall out of the freezer. next check to see if the fan is running in the freezer (evaporator fan) This fan is what circulates the air from the freezer to the fridge. If it does run then you have a defrost problem (if ice is on the coils and back wall). Then replace defrost timer, heater, and thermostat.
