Jenn-Air JFC2089HES Freezer Working but not Refrigerator

We have a Jenn-Air French door style refrigerator (model JFC2089HES) that was making noise. A service tech came out and was able to solve the noise problem (something was vibrating). In any case after he left the refrigerator stopped cooling but the freezer worked. Oddly the temp in the freezer started reading -10 degrees or more.

The technician came back and said we must have a bad "jazz board", shut the refrigerator and freezer off and told us to let it defrost overnight (with the doors open). However it seemed like it was still running (the control panel said OFF for both freezer and refrigerator) and it did not defrost overnight.

I called the service tech back and now he says (after consulting with a peer) that it must be the control board which is no longer available. Anyone have any ideas on this? Could it be something else? I tried calling Jenn Air customer support but gave up after being on hold for 30 minutes.

Do you see frost build-up on the back panel inside the freezer? Do you hear the evaporator(freezer) fan running when you open the freezer door?

Take a photo of your back panel inside the freezer so we can see it too please.

Hi, yes there was frost built up on the back panel and around the vents in the rear of the freezer. We could hear something running (maybe the fan) while the controls were set to OFF and we had the doors open to defrost it. As I said this morning there was still frost on the back panel & around vents in the freezer so we unplugged it and let it defrost. It defrosted so we plugged it back in to see if it will cool down. Unfortunately I didn't take pics of the frost build-up.

Ok, then it's either your defrost thermostat, defrost heater, or JAZZ board.

You would then need to ohm your defrost thermostat(WHILE ITS FROSTY) with a multimeter to check for continuity. Normal ohm reading will be 0 ohms. Make sure your Refrigerator stays unplug before testing it.

The defrost thermostat snaps on the top of your evaporator coil. Also if you notice a big bulge on it, then that's definitely the problem.

Here's the defrost thermostat for your model you can order if needed:
WP67003426 Defrost Thermostat


If your defrost thermostat is good, then ohm test the defrost heater, once you click the part link to it below, you will see a video on HOW TO ohm test it, make sure your refrigerator stays unplugged when ohm testing it.

Here's the defrost heater for your model you can order if needed:
Defrost Heater Assembly WP67002493


If both the defrost thermostat and defrost heater are good, then it can only be your JAZZ control board that's the culprit.

The tech is correct, the JAZZ board has been discontinued: WP12782036SP Electronic Control Board
