Thread: Maytag MZD2766GE Refrigerator Not Cooling

Hello,
I am having the same problem with my refrigerator not cooling on the frig side do I have to remove the ice maker to access the coil and fan?
Thank you
Steve

Hi Steve,

Lets first check your defrost thermostat and heater, No you don't need to remove the ice maker.

Remove the back panel from inside the freezer, its #20 and see if the evaporator coils #8 are massively frosted up.



If so Ohm your defrost thermostat for continuity while its still frosty to get a proper reading, should read 0-1 ohm. If the defrost thermostat is not frosty when you ohm it, you will get a high reading.

Here's the defrost thermostat heater assembly for your model:
Manufacturer part number 61006199 is RepairClinic item number 1025806


Put your ohm meter probes in the 2 white wire plastic connections, remember it has to be still frosty for a proper reading. Should read 0 ohms.

Then put your ohm meter probes in the black and middle white wire plastic connections, that will ohm your defrost heater, should read between 11-50 ohms.

Unplug your refrigerator first!

If the defrost thermostat ohms at 0-1 while its frosty, and the defrost heater is between 11-50 ohms then order the adaptive defrost control board.

Here's the adaptive defrost control board for your model you can order here:
Manufacturer part number 61005988 is RepairClinic item number 948430


Watch this video to access/replace the ADC board:

Let us know what you find.

Thanks Jake,
I checked out the defrost heater and thermostat last night on the heater i got 22 ohms the thermostat was 1 ohms I guess they are ok, but I ordered the ADC board and the heater unit as the frig is 9 years old. I figured it couldn't hurt. My unit was iced up solid.
Thanks for all the help. I figure replacing the heater unit is pretty strait forward and I saw the video on replacing the ADC board so I will let you know how I make out.
Thank you,
Steve

Save the old heater. It's still good.

Ok Steve, sounds good, keep us posted.

Jake,
I replaced the parts last night. I put a thermometer in a glass of water and set the settings to # 6 on both freezer and frig. woke up this morning for work at 4:30 and check frig temp was 38 degrees looks like its working like it should.
Thanks again for all your help, the website is very helpful and saved me $$.
Thank you,
Steve

Excellent Steve, good job.
