Question about Maytag Dual Cool 25 cu. ft. Side-by-Side Refrigerator MSD2556

Maytag 25 cu side by side

My fridge keeps freezing up... I just defrosted it last month and again, the coils (just about to the fan) are frozen.. I did note a crack in the wall of the freezer last month and wondered if that was the culprit... is the problem? What do you seal it with... And... the last time it froze up I used my blowdryer to speed up the defrost time and kinda warped the other side of the freezer... yikes..... I called Maytag and they want to charge for a troubleshooting question...anyway... the freezer works well... I knew there was going to be a problem when my food on the left side started freezing... sure enough..

Re: Maytag 25 cu side by side

Sounds like your defrost system isn't working. There is a timer that turns off the compressor and fans then turns on the heater under the coils to defrost them. The defrost bi-metal thermostat could be "open" and not letting power to the heat element, the heat element itself could be bad or the defrost timer could be bad, that's about it for the defrost cycle system. I see this quite a bit and it's "usually" the adaptive defrost timer. Under the fridge kickpanel in the front is some paperwork and troubleshooting sheets. I think this model you push the light switch in 5 times in 10 seconds to force a defrost cycle for testing. With the unit running (compressor, evap fan, condensor fan all running) in a normal cooling cycle open the fresh food door and press the light switch in 5 times within 10 seconds. If all the compressor and fans turn off right away then the adaptive defrost board is OK and it's the heat element or bi-metal. I'll bet it's the adaptive defrost board though... here's a diagram of where it is and where to get one. It's REAL easy to get to and change out (then test as above).

Our fridge keeps freezing up & we keep

You have a problem in your defrosting circuit. To troubleshoot it, you will need a voltmeter, some basic hand tools, and an electrical schematic. You can download the schematic from the Maytag web site.

I had a similar experience, and the problem was a defective defrost thermostat. A replacement thermostat cost $6 + $10 shipping. It was located on the back wall of the freezer behind the panel and beside the coils.

There are lots of appliance part dealers on the internet. Do a search for appliance parts, and take your pick of vendors. The web sites will have manuals, so enter your model number and look through the parts list for the part you wish to purchase. I would not recommend just replacing parts until you stumble across something that works. Take the time to figure out which part is defective using a voltmeter and fix the problem the first time.

My fridge keeps freezing my food

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. Make sure this fan is running. You may have to hold the door switch in for it to run. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.
The problem could be the electronic control if you have one or the mechanical linkages.

The refrigerator side won't cool and the coils are frozen. I have deiced the coils anyone know why it does this?

if the coil keeps freezing over it could be a few things, if the fan is working, it could be a problem with the defrost cycle, defrost bi metal, defrost timer, or defrost heater would need checked to determin which componet is bad.

Whirlpool gold:upper half of refridgerator side not cold

Either the evap fan has a problem, or the defrost system has failed. You should never see frost in the freezer section as the defrost sensor should sense that the coils need to be defrosted before that much frost accumulates.

Unplugging to clean out helped because the frost got a chance to melt away.

If you find the evap motor is running, then the things to check are the defrost sensor, the defrost timer, and the defrost heater.

sounds like a defrost problem. most of the time it's the heaters behind the coils.

Maytag MZD2766GES side-by-side Refrigerator warm

is it frozen up? do you have any air flow thru the air tunnel from the freeze to the fridge? Check your air flow with the door switch pushed in. also check to see if the damper door opens... 1) if it is iced up you have a defrost problem. most likely a defrost timer. Turn off or unplug untill all the ice has melted off the evaporator back of the freezer..plug back in and it will work fine untill the ice builds up again. if this work you do have a defrost problem.. if not let me know and we can go deeper...

Refrigerator won't get cold

You likely have a defrost cycle failure. The freezer's cooling coils need to be frosty and cold so the air that the fan pulls over them can cool the fridge section. If the defrost cycle fails, the coils freeze up to a block of ice and air flow suffers (fridge is about 55 degrees F). The freezer stays cold only because there's a block of ice in there now... sometimes that cold "sinks" to the bottom and only the food at the bottom stays frozen (and can even freeze food at the bottom of the fridge compartment while the rest is warm). To be sure, you'll need to take the rear interior panel off the freezer back wall and check the coils to see if they are frozen solid. If they are then there's a defrost cycle failure. If they are showing a nice white frosty pattern evenly all over the coils then that's normal and maybe the evap fan (right above the coils) is not blowing air up properly or is not working at all. That fan should run if the compressor is running, etc. the only time it doesn't run is during an actual defrost cycle. Once you find out what condition the coils are in it should be simple to direct you further on the problem.
