Question about Maytag 22.6 cu. ft. Side-By-Side Refrigerator with PuriClean II Ice and Water
1 Answer
The light on the outside door (where the ice/water dispenser is) won't turn off. It is dimmer than when you hit the 'light' button, but it stays on constantly when the door is shut. The 'light' button works and turns the bulb brighter, but when you turn it off, it just dims and doesn't go out. The light shuts off when the door is open and turns back on when its closed. Model Number MSD2456GEB

Hi
Reprogramming your refrigerator to only light up when the dispenser is in use saves energy and keepsyour house darker at night. The light is controlled using the buttons above the water dispenser mechanism.Press and hold the "Lock" or "Lock Controls" button for three seconds to activate the controls if they currently are locked.Tap the "Light" button to switch off the light.Press and hold the "Lock" button for another three seconds to lock the controls from further changes. The light now only comes on when the dispenser is active.
If the above procedure won't work then this will be the cause of a faulty switch. This light switch is an integrated part of the dispenser control circuit board. This will require you, or your service tech to replace the entire dispenser/ice maker control board. It will be located just behind the dispenser fascia, mounted on a bracket. the actual light switch circuit is mounted on this board.
Try this procedure:-
Shutdown the unit for five minutes. Simply unplug the unit for this length of time. This will reset the board, and possibly, fix this fault if it is not to severe. If the shutdown dose not correct the switch action, simply replace the dispenser/switch control circuit board.
Please get back to us if you have further query or else please accept the solution.

Since there is water that flows to the water dispenser, the water valve is working. Now, there's a spout that water flows from to the icemaker tray. Look for it. It's located on the back wall inside the freezer and maybe behind the icemaker tray. Check and see if it's frozen. If so, defrost your freezer by turning the temperature gauge to off position. Wait a while until it's defrosted, then turn it back on.
Next, make sure that the metal wire is in down position.

If that doesn't work, your icemaker maybe defective and needs replacement.

On top of the fridge underneath the plastic cover for the door hinge probably on the door with the water/ice dispenser should be a wiring harness. This runs the ice dispenser and water. There should be a wiring harness plug there. Try unplugging it and reconnecting. This may be the cause since you said it's intermittent and with opening and closing the door it may be causing the plug to ever so slightly move around and loose electrical connection.

Yes it sounds like you may just have a short circuit below the keyboard overlay=> 61005274 Dispenser Control Board Here is a photo of the fountain parts=> MSD2756GES_Dispenser_Parts and tale a look at the wiring diagram=> SD2756GES_Wiring_Diagram
First I would disconnect the pin plug here=>
and follow the directions after clicking. I will be HERE to help or here on Fixya, Please rate this solution, Thanks Sea Breeze

we can not get water or ice out of the dispenser

Either the paddle for the ice/water dispenser is stuck or you have a bad microswitch behind the dispenser.
To stop the ice/water from dispensing open the freezer door and press or hold the child lock button down. Once the unit is in child lock mode you can shut the door without energizing the dispenser.
Another option is to remove the upper freezer door hinge cover and disconnect the wire connector up there. This will remove voltage from the dispenser as well. Then either replace the paddle or switch. Sometimes the paddles/switches will get stuck because of splash up from ice dropping in sugary drinks.

Door Panel Locked
Press Door Alarm and Freezer "-" at the same time, then release Door Alarm but continue pressing Freezer "-". You will see PE _ _ _ _.
Press Freezer "-" until PE # # # # shows on the panel.
Using Freezer "+" to move cursor, Refrigerator "+" and "-" to change numbers, bring all numbers to "0". Press Freezer "-" until PE and numbers blink. Unplug refrigerator for 45 seconds, never beyond 1 minute or you'll have to start over.
Look inside refrigerator door and locate the serial sticker. To the right of the serial number is the CODE ####. Plug in your refrigerator.
Press Door Alarm and Freezer "-" at the same time, then release Door Alarm but continue to press Freezer "-". Using the same method as above, enter the four digit CODE number you found on the serial sticker. Press Freezer "-" until PE and numbers blink. You have just reset your panel. Unplug for 45 seconds. Plug in refrigerator and you should now have full use of your door panel.
This unit has a built in safety timer mechanism. If it dispenses water for two minutes, it assumes it is flooding your house and shuts the panel down. If you are filling a pitcher of water, just stop dispensing halfway through to reset the safety timer.

removed freezer door and drawer by lifting and pulling out. removed ice maker with 3 screws and disconnect electrical plug. applied heat with hair dryer to water line. and all is well

Don't be duped into thinking the display/dispenser board is the culprit. It may come a surprise, but this failure is often misdiagnosed. Because the dispenser is causing such a ruckus or because the display itself is blank or flickering, folks are led to believe that the display control board itself is the part that has failed. Looking at the history of our board evaluations, this little tiny control board rarely fails. And as crazy as it may seem, it is the main control board, aka the high voltage control of the fridge that is causing your refrigerator not to cool and the dispenser to be erratic.... This is the main control board of the refrigerator, located on the back of the unit. I've attached photos of what this main control board looks like. This main control board will need to be repaired to replaced.

Since it's only one dispensor unit you should be able to eliminate "common" items and find out what controls just that one dispensor. The faint click may be from a bad relay (relay coil works but doesn't pass voltage on contacts). You will likely have to take the thing apart to check the control board. Here's a diagram of the unit so you can see where everything is at. I'd suspect the control board relay that controls that particular dispensor is bad or a loose wire, etc. http://www.partselect.com/Schematics/Maytag/VM10-1.gif
