My freezer doesn't defrost anymore - Maytag MCD2257H Side by Side Refrigerator

Hello there,
When your refrigerator starts building up ice at the back of the refrigerator and is not getting cold, the problem actually is caused by defrost settings of the refrigerator.
The defrost settings is composed of the defrost thermostat, defrost heater and the defrost timer. If any of the three should go bad, then the refrigerator would begin to build up ice and not cool.

You will have to test the defrost thermostat, heater and timer. Mostly the problem used to be the defrost thermostat.Once you check the three and see that they are okay, then you need to refill the gas cylinder with refrigerant.

Clean the condenser coil, refill refrigerant and test the thermostat, heater and timer.

That would get your refrigerator up and running.

All the best.

Its defrost problem.When the freezer section gets cold and reaches its required cooling temperature, after that the frost on freezer section starts defrosting and the cooling fan in the freezer section blows this cool air from freezer to fridge. But if the defrost cycle does not start then over ice will get collected on freezer ventilations and that will block the air passing section from freezer to fridge, so the freezer gets cool but fridge section does not cool.Try manual defrost by unplugging the refrigerator from main power outlet for 24 hours then reconnect it and check, if the same problem is noticed again,. If yes then its defrost board problem. The defrost board located in the back of fridge section. You can get required parts from www.repairclinic.com or from online sears part site. ------------- Thank you.

Hi,
This is a common defrost problem, The ice
is not being melted by the defrost system. he fan can't blow into ref.
Take out back panel of freezer to check for icw build up. The coils should be clean.
There are three components to a defrost system- a heater,heater thermostat, and a timer unless you have a defrost electronic card.
Its best handled by a Technician but you could possibly do it by taking your model number to the nearest appliance parts store and asking for the parts. They are mostly located in freezer ,behind back panel on freezer coils.except the card which is usually located in ref The parts store will have info
Also check evaporator fan in freezer
Also check fan undernearh Ref in the rear
Clean condenser coils underneath
If this was helpful please rate me
Thanks for using fixya

the defrosting mode could a problem with the defroster timer. as for the bottom one if the top is not cooling the bottom one wont either. the freezer fan is what also keeps the bottom frig cool. the defrost timer should be on the bottom frig close to the ligth.

The Thermostat Defrost its not working anymore, it doesn't defrost anymore and it acumulate ice on the gap that flows the is in between the fridge and the freezer. so what you got to do is defrost your refrigerator and remove the back wall, and locate the defrost, cut it and take it to an appliance part store, and get a new one and just put it back and it should work like new!! :)

, you might have a defrost problem. Frost free models have a heating element that is controlled by a timer to automatically defrost ice, defrost timer turns on defrost heating element every 12 hours to melt ice in freezer and allow good air flow.
You can test defrost element with an ohm meter(located inside freezer coils-will have two wires going to a plug connection), if OK replace defrost timer (located in various places depending on make and model

Turn cold control to Max. This keeps your compressor running for this troubleshooting exercise. Find and manually advance the defrost timer with a screwdriver or something similar. This will shut the compressor down and bring the defrost heater on. If this happens then you will know that your timer is bad.

If it is not that, the next thing to look at is the defrost heater itself or the thermal overload on your defrost heater. This keeps your defroster from overheating.

sounds as though the defrost system has failed or the freezer defrost drain is blocked. take off the back panel of the freezer and see if excess ice build up. if so, defrost carefully with a hairdryer. at bottom is a drain. check if blocked with ice and if so melt off with hot water till water flows away freely. if i'm right, appliance will start to work. if fault re-occure then defrost system is at fault
