Question about Maytag MSD2756G Side by Side Refrigerator
Your solutions suggest to follow certain actions but I need to know how to do the actions. So for my situation of an iced up coil, how do I check to see if the Defrost timer is advancing. How do I check to see if the defrost heater is working. Then how do I see if the Thermostat limiter is working. Where do I go to get procedures for these suggestions.
Please disconnect power from your refrigerator before attempting the following! You will likely need an adaptive defrost board for your refrigerator. The defrost thermostat and heater is only available as an assembly and can be checked while the unit is freezing by checking the resistance with a multimeter. there should be some resistance to the heater assembly but not infinite. If the resistance is high then the heater assembly will have to be replaced. Your model has an adaptive defrost board located in the upper right hand back portion of the control panel in the refrigerator side. This cover is removed by placing your fingers in the 2 indentations at the back of the cover one on the left and one on the right and pulling down and forward. Once the cover is off there are a couple of screws directly above the lights which have to be removed and a couple of hex head screws behind the number faceplate and on the back wall near the water filter. Once these are removed the whole housing will come down the board is at the far back right. It will either be a bare circuit board or a small white box. Just unplug it and replace it with a new one. This will correct 99% of the defrost problems on this line of refrigerators.

Clark, Im not sure who you are refering to in your post, but I will try to give you some insight on this model. These Maytag adaptive defrost boards can be a pain to get at sometimes. For the model posted, the adaptive defrost board will be in the back right hand corner of the control. You have to drop the light shield. First remove the control knob ends. On the shield there will be two tabs on each side in the rear. Push the tab in while pulling straing out on the shield. Then there will be screws holding the light itslef and the control housing assy to the top. The adaptive defrost sits in this housing. When you get to the board, depending on which one you have it will read Dstat-door-L1 or dstat-test-L1. If it reads the first one you should be able to initiate a defrost by cycling the cold control on and off 3 times in six seconds, leaving it in the on position. If it's the second one you will need to short L1 to test with a small screw driver. Do this with the harness on. If it jumps into defrost and immediatley jumps back out, it's your board. The calrod heater and defrost terminator come together as one kit. I usually don't see too many of them go bad. It's usually a board problem. You can go to Sears.com under appliance, post your model number and bring up a diagram of the control area. Hope I have been of some insight...Catriver..post back.

If your refrigerator freezer compartment is cold, but the refrigerator compartment is warm--It could be a defrost problem. When a defrost problem occurs, it is usually the fault of one or more of three basic parts: defrost timer/adaptive defrost control, freezer thermostat or the defrost heater element. See in detail how to dx and fix: Refrigerator Defrost Parts .
