On side by side fridge/freezer, the freezer wont defrost, the coils get filled with frost and freezer wont freeze. I defrosted manually, then the freeze was on but now coils are all filled with frost again. Fridge is Maytag Plus MSD2456DEW. HELP! Greg

Condenser coils do not frost ....If ice (more than just frost) is present in the freezer you have a defrost problem
check the following ....
- air circulating fan in freezer
-defrost circuit .... defrost heater, defrost thermostat, and the defrost timer If you have a control logic board the defrost control is part of the logic board
this fan needs to run when the compressor runs,check fan blade for being jammed by ice if you have this much ice on back wall as ice will stall motor,if no fan there will be no cool air to refrige compartment also the defrost drain tray will fill with water then freeze over which in turn floods the freezer floor and refrige compartments cause it cannot drain to the pan in the bottom
What you have is probably a bad defrost heater element is my first inclination. I would look for frost buildup on the backside of the bottom drawer. That is a sure sign of defrost failure. And most defrost failures turn out to be broken heaters. The defrost heaters mount on the evaporator coils and simply heat the area for a few seconds to melt frost. If left alone that frost will trun into snow and then into air flow blocking slab of ice and fail fresh food cooling. I have a 3 door repair manual you may want to look through just to see what you are up against. To do this repair the ice maker and all the rails drawers bins and food must come out so you can get to the rear where the evap coil and defrost heater is located.
It is normal for the coils to frost evenly all over but if it's not defrosted it will build up preventing proper cooling. After replacing your defrost components make sure the frost is being melted. The motherboard determines when to defrost based you your use of the freezer/fridge. It should defrost from once a day to once every two or three days. Is the fan in the freezer running? It won't cool right without it. It should run when the compressor runs. Are the coils frosting evenly? Uneven frost means it is low on freon and requires a tech to repair. Is the fan underneath the fridge near the compressor running when the compressor runs. If not It won't cool properly. Does the compressor ever cut off as it should when it reaches the selected temp.
Your evaporator coils frost up in normal use and every eight hours or so the entire unit shuts down and the defrost heater comes on to melt the frost. This cycle last about 20 minutes. The melted frost drips into a drain pan and through a drain tube to the drain tray under the freezer/refrigerator where it's evaporated by the condenser fan.
If the evaporator coils behind the back panel of the freezer
are icing up because of auto defrost failure that will stop the circulation of
cold air and eventually affect the freezer too.
check defrost timer, defrost heater, defrost thermostat. In
most newer models the timer has been replaced by an electronic control board.
If the heater and thermostat are ok it’ll be the control.
You can turn the defrost timer till it clicks
and everything shuts down. The heater should now come on. If it does, replace
the timer. If it doesn't, check the heater and defrost thermostat. Turn the
timer again till everything starts back up to end the defrost cycle.
How to check
if u have frost build up in the freezer it will affect the temperature and it needs to defrost problems could be defrost timer. thermostat. terminator. heater s. unit problems (unlikely) if even frost coating.
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.
