Question about Maytag MBB2256G Bottom Freezer Refrigerator

1 Answer

Freezer compartment not defrosting

MBB2256GEW is the model # of this maytag bottom freezer. It appears that a component in the defrost cycle has failed as this is now the 2nd time in 3 weeks that the freezer coils have iced up. What do you suggest? I've read most of your posts and am very impressed with your knowledge. Hopefully you can point me in the right direction! Thanks in advance. Bruce Carwardine

    OK, I get a consistent reading of 30.9 ohms

  • Bruce Carwardine May 26, 2007

    What's called the "defrost terminator" in the wiring diagram, has a bulged look to it. The inner blue plastic has started to pop out of its aluminum cup.Resistance across this is ~30 kohms

Most refrigerators utilize an electrical heater coil to prevent freeze-ups. your coil has most likely failed. hard to pinpoint without being there, however, i would check its resistance with an ohm-meter with power off: if no resistance, then coil is burned out. look for around 2 ohms

You have one or more of your defrost components that are bad. Defrost heater, defrost thermostat, and defrost timer or board depending on model are the 3 components.

Siemens ka..n freezer problem


Look inside the back wall of the freezer to see if you have a layer of frost building. If yes this will indicate that the refrigerator is missing its defrost cycle. When you miss defrost it is usally number 1 the defrost control. Number 2 is the defrost heater has burned out and #3 the defrost thermostat. For you to look up the correct replacement parts you will need to find your refrigerators model number found most times inside the fresh food compartment.

Hello,
Yes it does sound like it could be a component of the defrost system thats the problem OR the fan in the freezer that circulates cold air into the fresh food compartment

If ya see frost build up on the back wall of the freezer and do indeed hear the fan running it will be a defrost problem

if ya dont hear the fan in the freezer running thats very possibly the problem

Defrost problem: 3 components. Defrost Heater. Timer (circuit board or motorized) & Thermostat.
Remove cover on the inside back wall (usually 6 screws). Note frost pattern. (bottom of evaporator coil)
Put refrigerator into defrost cycle and note the defrost heater come on, or not. (careful heater can glow red hot)... Unplug Frige and test defrost components. Replace bad component... Refrigerator should defrost every 8 hours. when the cycle slows or quits the freezer will freeze over the evaporator coil and no air flow = no cold air...

FREEZER IS FINE. FRIDGE STILL NOT COOLING


it sounds like your circulation fan is not working. it is located in the freezer compartment in front of the evaporator or very close to it. you should hear running either all the time except in the defrost cycle. on some models the fan will shut down when you open the freezer door and restart when you close it. if the fan is OK you have a problem in your defrost circuit. probably a bad heating element or a bad defrost cutout switch or bad connections in the freezer compartment. sometimes the defrost timer can go bad but not often. I have found in my experience that the problem is usually the other two components I mentioned or bad connections.

Water pools and freezes at bottom of the freezer. When tray is full water leaks out of freezer onto kitchen floor.


I am uncertain as to what you mean by "when tray is full"? However, you probably have a clogged drain in the freezer compartment. During the defrost cycle, which usually occurs every eight hours, defrost components (defrost thermostat & heater(s) ) melt the ice that has accumulated on the evaporator coil in the freezer compartment. The water from the melted ice drains through a hole in the freezer compartment (behind the freezer's rear panel) and accumulates in a drain pan below the refrigerator. This water should evaporate over time, whereby you should not have to regularly empty the drain pan. If the drain hole is clogged (usually from algae or other debris, etc.), the water finds another path to flow (which is inside the bottom of your freezer compartment). This water will usually freeze. Water will then flow toward the front of your freezer compartment and out of the door on to the floor when you open the door.

Contact an appliance service company to unclog your freezer drain. Also have them check your defrost components (thermostat & heater(s)).

Freezer compartment ice build-up


too defrost just open the doors for a day with the unit unplugged. as far as why it is frosting up check door seals make sure they are all good and seal it up well and that should take care of it.

I do not know how to defrost my freezer Model MQU165BEW


There are no buttons to defrost your freezer except the off button. The unit is a self defrost. If it is freezing up then one of the defrost components have malfunctioned.

Freezer Not Defrosting


Hi Rusty...

There are 3 componants to most defrosting systems. The defrost heater, the defrost thermostat, and the defrost relay. First you must remove and store your perishables safely. Then remove the panels in the freezer compartment to expose the evaporator. The defrost heaters will be attached to the evaporator and will have wires extending from them. Using an ohmmeter, see if there is continuity across the heater. If not replace it. Find the wiring diagram on the back of the unit and check for voltage into and out of the defrost relay. All of these items should be availible from a local refrigeration supply facilitiy.
