    Thanks. I heard that some of these Adaptive Defrost systems require re-programming. This isn't one of THOSE is it?

First try to force a defrost by turning the control inside the refrigerator off, then on, three times within 6 seconds. If it goes into defrost, the ADB is not the problem. If it does not go into a forced defrost, just drop the control panel down by loosening 5 screws (3 at the perimeter of the housing, and two near the light bulbs. The housing should now pull slightly forward and down. The ADB is inside a plastic shroud about the dimension of an index card, and about an inch thick. It unplugs directly from the wiring harness.

You will find the defrost control board inside the panel that contains the two turn knobs where you control the temp inside both compartments. It's inside your fresh food section of your unit. Pull the two knobs off, take the screw out of the side and remove plastic piece. Between the two temp controls there is a square box. The board is located inside the box. Take box apart and replace board.

If you would like a parts blowup of the unit, go to and enter your model number. Select the Control panel to the left. This will give you a blowup of the parts.

Hope this helpout and Good luck...

The automatic defrost cycle is not working in freezer. Can this just be low on freon and making it freeze up? I can defrost and refrigerator will work fine till it freezes up again.

Most times on your model it is the ADC or adaptive defrost control. Part number 13 in photo here=> MSD2756GEW Maytag Refrigerator Control Panel This is behind your controls inside your fresh food compartment.

When the fresh food compartment begins to get too cold is usually when the part #8 in that photo goes bad and that is called the auto air damper

More on that part next time. I believe you will be fine once the ADC is changed, Thanks, Sea Breeze

Not cooiling on the refrigerator side

First I want you to look into back of the freezer compartment. If ice is building up on the rear wall we have a defrost problem. But the way you explained it sounds more like the auto damper part number Click Here=> 61005971 where there is no photo and in photo # 8 here=> MZD2766GEQ Fresh Food Section Contros We need to test it first by doing this test aslisted on section2-10 or in scroll bar at top of page 38. Click here=> MZD2766GEQ Behind the back wall of the Model MZD2766GES Freezer Compartment the defrost heater and defrost thermostat are in photo and listed in photo as part 12. That part needs to be check with an ohm meter to see if that is stopping defrost. Click here for that part Number 61006199 I would like you to see the parts breakdown Click Here=> MZD2766GES Freezer Compartment The most likely reason for this happening is and fresh food section is here=> MZD2766GES Fresh Food Section and part 13 in photo is 13 and that Part Number is Click Here=> 61005988 Adaptive Defrost
If you have questions please contact me here on Fixya or through my Web Site=> Appliance 911 Hope this was helpful, Sea Breeze

Because you mentioned that last week you had an ice problem I need to ask was anything done to fix or check the defrost system? The number one reason for this is the Adaptive Defrost Control part number 61005988 If this is OK then we need to check the defrost heater and defrost thermostat. The ADC is located inside the fresh food compartment and behind the control panel used to adjust the temperatures in the freezer and refrigerator. I will be here if you need my help, Thanks, Sea Breeze

Defrost Heater Resistance Range

21.3 ohms is just fine for a defrost heater. this heater is low wattage since it is an adaptive defrost. you could have problem with temperature sensor since you have replaced the board already.

tnx for using fixya,

Defrost timer board for mzd2766geq

Defrost control board is in the top of the refrigerator behind the two levers that control the temperature. You have to take off the plastic cover. There are two screws and then you slide to cover to the side to remove. The board is in a white plastic housing.
