Most likely the problem with your refrigerator is a faulty Adaptive Defrost Control (#13 on the break down diagram). This is most common problem with all Maytag and Jenn Air refrigerators made since about 1997.

The following article on our forum will explain in detail how to run a continuity test using either an analog meter or a digital meter - How to check continuity with Ohmmeter.

- The part number for the Adaptive Defrost Control is AP4070403

gene,
i can't seem to attach the documents to post. i think the attachments are too big.? is there another way i can send them to you?

Thanks,

You can decrease the size through a picture editor or you can try to upload the picture in a web storage and post the link.

I changed it out - how long should this take to kick in and solve the problem if indeed that is what was wrong?

If the freezer was completely defrosted then it should take about 24 hours to reach the proper temperature. If the evaporator coil is blocked with the ice then I would recommend to defrost it first.

Gene,
I've read your posts regarding defrost system, and am convinced this is my problem; but I'm puzzled still. First, I'm puzzled why my model # doesn't show up on any sears parts website, but model #'s that are very close do show up; so I have used parts diagrams from the very similar model# 25359482991. My original symptom was warm refrigerator, which led me to find ice on evaporator coils. I manually defrosted evap coils, then plugged back in, and it worked fine. The defrost system kicked in regularly, and I could see ice on coils melt. It worked great for a month. Yesterday, same problem reoccurred. So, I defrosted evap coils manually. I found your post on defrost system, so I located defrost timer, turned to advance until I heard click, observed defrosting evap coil, after 35 minutes, timer clicked and freezer started back up. All seems like it is working fine. However, I am confused why the ice buildup a month ago, and again yesterday. I have not done a continuity check on defrost heater because I saw the ice on the evap coil melt when in defrost mode, so it must have continuity. What is your best guess? Thanks, David.

Hi David,

The only part in the defrost system which can have an intermittent problem is the defrost timer. In the situation you described, I would replace it first. The defrost thermostat could do it too, but it is much rare.

- The part number for the defrost timer is AP2111929

Thank Gene; I ordered a defrost timer yesterday and it should be here tomorrow. If that's not it, I'll call again; otherwise, thanks a lot. David

You are welcome. Keep us posted.

Gene,

I have a similar problem but suspect a different cause. With my refrigerator and freezer temperature controls set at the manufacturers recommended settings, my frig temp is about 40F-45F and the freezer is 0F-10F. If I lower the frig temp setpoint, it also raises my freezer temp. With both controls at the lowest settings, my frig runs 30f-35F but the freezer runs 20F-25F (also notice some condensation on the top and right inside panels of the freezer at this point). What temperatures are acceptable for both compartments? I've not seen any frost on the inside rear panel of the freezer so I don't suspect the defrost components are bad and I've checked for blockages in the air ducts and it's clear. Could this be a thermostat problem? Something else? Any help is appreciated.
