The refrigerator is freezing everything inside!Have bascilcally turned the thermostat down to 2 to keep things thawed out and it still doesnt work???

Manually turning the defrost timer will not tell you if the timer is working, it only tells you the switching inside works, The defrost timer has a motor inside that turns it through it's cycles, this would be the part of the defrost timer that stops working.

But since the unit is freezing and thawing, The problem is more likely the defrost thermostat has came loose or is defective.

Start lowering down temperature, you may need to defrost fridge overnight.

How to Defrost Refrigerator Defrost Timer Problem

Water Running in refrigerator from Freezer

With the defrost timer being replaced already it sounds as if the repairman is not looking at the real problem. Unit works for 2 days then things start thawing. Hint Hint... it is not defrosting. There is a heating element inside the freezer section attached underneath the internal tubing that melts the ice every 6 to 8 hours via the defrost timer depending on the defrost timer installed. To prove that it is not defrosting..... just unplug the unit and place a stand fan blowing into the freezer for about 90 minutes. I would bet that once you plug it back in it wil work for 2 days and the problem once again repeats. With 2 calls on the same unit and you still have the same problem I would be calling the service people back and demand they fully troubleshoot the defrosting element and thermostat. Personally this is an unstatisfactory performance of an in home service by a repairman. With the exception of a new part if required, they should wave any labor and service call fees.

check the setting in the ref part set on a lower setting if this doesnt take care of the problem replace the thermostat

check 2 things. Make sure the fill tube is going downwards to the cup inside. The second thing is when the valve shuts off make sure it closes right away. If it doesnt then replace the valve.

If the fridge side is frozen you have a door seal issue.
If the freezer side is frozen you have a defrost component issue.
Your post was not clear as to which side is frozen.

Possible defrost timer or thermostat failure.

This refrigerator only has one thermostat located in the fresh food compartment it is designed to activate the sealed system (cooling) until it reaches approximately 37 deg f in the fresh food compartment. The damper controls how fast the cold air can move from the freezer compartment to the fresh food compartment. Allowing you to control the temp in the freezer by controlling the flow of cold air to the thermostat.

You have one of two problems.
#1 your thermostat is no longer opening when it achieves set temp. fix = replace thermostat pn 61005798 $35
#2 your damper arm or assemblie has broken. Fix = Replace damper or broken arm and actuator.

Try turning down the freezer a little.

You can 'thaw' the water line in the door by hanging some towels in the freezer with the door open. Should thaw in a couple hours. At least this way you don't need to empty the freezer.
