Thank you so much!!
Right now it's running great because my husband pulled the back panel off and got ice out of everywhere, including the drain which was solidly blocked. He just had 1 question:
When the fridge is going into defrost mode the heater does not appear to be turning on. When we had it all apart and advanced it into defrost mode it was cold, and now that everything is back together when it goes into defrost mode we pull the bottom drawer out of the freezer and look and we don't see any evidence of the heater being on.
Would the ice buildup in the areas you said to check cause the heater to not turn on?
Thank you again for all your help; my husband is going to check those places tonight. :)

You are welcome. The defrost heater test should show some resistance and the defrost thermostat continuity test should show closed circuit when it's bellow 30°F (the exact temperature range is written on the thermostat). - The defrost thermostat Part number: AP4299920

Okay, i finally got the back panel off and discovered frost all over the coils. I am trying to go by the guide on the original post, but i cannot find the defrost timer. I checked the diagram and not luck. I am starting to think this refrigerator doesnt have one. Model PSC23NSTDSS.
Help,
Chris

This may be a silly question, but when you say the defrost heater should show some resistance, I want to make sure we understand that. When we tested the defrost heater with an analog multimeter it read zero.
Is that good?

Is that good?... 0 Ohms reading means the heater is shorted. In such case it has to be replaced. Gene.

So I've read many of the posts in this thread and searched it for my model and haven't found an answer. I have a Kitchenaid KSRA25FKSS00. Freezer is fine. Refrigerator is not cooling. I've checked the coils and found no frost. the vents/diffusers and found no ice. I replaced the diffuser (with the slide louver to control airflow from the freezer to the fridge). This did not fix the problem. Any suggestions? Using a mirror to view the diffuser as it is installed, it appears that it is not opening.....

I checked this morning and the temp in the Freezer is -7 F with the digital control set at +1 F. I will check the condenser coils and the evap coils this evening.
If this is a problem with the sealed system, is it fixable? If so, is it worth it (financially)?

Ok, so we ordered in a new defrost heater, and the new one is also reading 0 ohms? I thought that meant it was bad?
Are we testing the heater wrong? He's hooking up the multimeter to both leads of the heater.
