Jim,

If you are sure that this is the fresh food control then this thermostat has to be replaced.

- The fresh food thermostat Part number: AP2116225

Part number: AP2116225



Another solution is to replace the whole control box. This kit includes both (freezer & fresh food) cold controls, damper control, defrost control board, wire harness and installation instructions. It will cost you more money but it will make the repair much more reliable.

- The control box kit Part number: AP5176342

Part number: AP5176342

Glad I found this place, was about to just start shopping for a new fridge.

I have a roper RT18BKXJW00 and this exactly describes my problem.
First time was around a year ago, found some info on another site, took off the back cover in the freezer and the coils were iced over solid.

About 3 months ago the ice was actually not just solid over the coils, but a layer of ice was on the outside cover (once i moved stuff out of my freezer to see it)

Fridge getting warm again, so its happened again. Obviously getting worse, just defrosted it again yesterday.

The OPs first post is excellent, the links were great, and it seems easy enough for me to try, I just need a slight push in the right direction before I start

1. Where is the defrost timer in this refer? Is it #4 in this diagram, and what do I actually turn if it is?
HTML Code:
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=261674&diagram_id=28259576#d28259576
2. if this unit doesnt have a defrost timer, then the problem is in the defrost heater or thermostat, is #4 in this diagram the ticket?

Thanks for any help in advance. Great resourse and post, outside of a little nudge, that post gives me the confidence to try and fix this myself.

Samsung RB215LABP
Bottom freezer model. Freezes well. Refrigerator temp no lower than 48 degrees.
I removed the panel inside the refer box to expose the evaporator.
Evap was frozen up. The evap fan works fine.
There are two thermistors (yellow wire sensors). One attached to the bottom of the evap, the other in the panel I removed to get to the evap. I checked resistance of each. One was 4.7k ohms, the other 5.0k ohms.
There is a plug with red/black wires. This goes to something that looks sort of like a cylinder with a cone on top. It is sealed in clear plastic and wrapped in soft foam.
There is another plug with red/white wires. This goes to the evap heater and drain tray heater. Evap heater reads 113 ohms. Drain tray heater reads 340 ohms.
Anyone have any ideas as to what is going on? I really need some help!

1. Yes, the defrost timer is shown as #4 on the diagram.

You have to turn the shaft which is inside the red circle on the attached picture.


2. The defrost heater is shown as #4 on the diagram. The defrost thermostat is not shown on the diagrams (don't ask me why) but the Part number: AP3108445

Part number: AP3108445



- The defrost timer Part number: AP2984369

Part number: AP2984369



- The defrost heater Part number: AP3997341

Part number: AP3997341

Hey Gene, or anyone out there...

I too am having the fridge warm (Almost 60 degrees F) and the freezer is fine.

I have read over a lot of this information, and I have not as of yet had a chance to dig into my fridge too much. I dont notice any amount of ice at least on initial visual inspection. In the fresh food side, there is zero airflow from the vents. It seems like I hear the fan running constantly.

I looked over the parts list for my fridge, I didnt see a damper unit, am I missing something?

Any commonly known issues for this fridge? Suggestions?

Kitchen Aid KSRS25CNWH00

The damper control (aka a diffuser) is shown as #15 on the diagram.

If the fan in the freezer is running but there is no air flow into the fresh food compartment, then most likely the damper control is the culprit. You can verify it by checking for 120 VAC to its motor (black and orange/black wires).

- The damper control Part number: AP3084126

Part number: AP3084126

Gene.
Thanks Gene. I'm not sure what I should be looking for though.
I did the following:
Press Super Cool and Fridge at the same time. Hold for 5 seconds.
The display turns off.
I press Super Freeze three times.
Fd is on the left side of the display and a beeping comes from the back of the fridge.
It never changed. I let it go for about 15 minutes. Nothing changed.
I'm not sure what was supposed to happen.

Check the defrost thermostat (#3 on the diagram) for continuity.
