Question about Kenmore 73502 / 73504 / 73509 Bottom Freezer Refrigerator
Freezer appears to be working, at least it's cold. Refrigerator is not working. There does not appear to be any air flow into refrigerator compartment. There is only a very slight frost on rear evaporator cover panel. I'm suspecting evaporator fan has failed (since there is absolutely no air flow into refrigerator section). Is there a procedure available to step through removal of ice maker, removal of cover, removal/replacement of fan ? Thanks...BOb.
It has a defrost problem. Most likely cause would be the defrost thermostat which clips onto the evaporator behind the back panel in the freezer. Next most common would be the defrost timer. Third would be the defrost heater. Let me know if you want to try to test these parts. If so I will need the entire model # from the sticker in the fridge or on older models on a plate at the bottom front below the door.

SOURCE: Frost buildup
It is not defrosting. You have to remove back wall of freezer where frost is and take hairdryer to melt away frost. You need to check defrost heater. This is on bottom of evaporator coils. It has wires going to it on both sides. This has to be checked for continuity. If ok on top of coils is a round unit called a defrost terminator. This needs to be checked for continuity also. This must be done before you defrost coils. It should have continuity when its cold.
If these are ok you probably have a bad timer or defrost board.

There is a panel over the evap. in back of the freezer section. Remove it and you will see the drain at the bottom of the freezer below the evap.. You will see a little tray with a hole in the center of it. You will need to clean out this tray and run a wire down through it to clean out the tube that runs to your drain pan. Don't use a coat hanger or anything too stiff as it may puncture or pop the hose off. It has to be something flexible but strong. That should do it!

I went ahead and signed up for Sears' service warranty since I knew I had to get someone to come out. IT costs $200/yr. They say it covers everything, but when the technician came out, he told me that it just covers $500 per visit. He said that a new motherboard and the labor alone was going to make it $498. Anyway, he had ordered a new motherboard. Apparently the motherboard wasn't working. It is located in the back bottom left side of the refrigerator behind the panel. There is a compartment on the lefthand side that slides out and houses the motherboard. He put that in and also had to fix the fan that is in the back of the freezer. That fan is the one that sends cool air up to the refrigerator part. When I had looked at the fan before the repair man came, it was not moving at all. So at least take a look at the fan in the freezer. Just take out the freezer drawers, and the fan is located in the top center of the freezer behind the compartment cover. Maybe that's the problem with your refrigerator, the fan. Hope that's all it is. Good luck!
