Hi, I'm curious about whether your original defrost heaters where faulty, did you ohm them out ( continuity ) ? Typically on your style of fridge made by what was at the time Maytag, now Whirlpool, it is the "adaptive defrost control" which fails. You'll also want to ohm out the "dts" ( defrost termination switch ) or defrost bi-metal or defrost thermostat as some refer to it. Back to the adaptive control though, it is actually located in the fridge compartment up in the far right corner covered by the light cover and temperature control/damper assembly shield. The part number for it listed at "repairclinic" is #948430 and is $67.45 as I write this. Let me know what you find. Thanks for coming to "fixya" for your inquiry. Let me know if I can assist you further and please take a moment to rate this info accordingly. Good luck. Macmarkus :)

My freezer (upper) works but my fridge (lower) doesn't. There's nothing clogging the vent. What could be the problem? Thank u!



My fridge is running but not cold enough: Start out with the easy stuff first...make sure the lights go out when you close the door(s), make sure the doors are closing properly and the gaskets are closing fully and are not torn or ripped. Check to make sure the evaporator fan in the freezer is working, this fan blows the cold air around. If the fan is not working, possible bad fan motor - check for power to the f


The most common fridge "not cooling" problem is a frost free failure. Remove the access panel in the freezer section to expose the evaporator coils. If the coils in the freezer section get plugged up with frost, this frost will block the evaporator fan motor from blowing the cold air around. The fan blade can also hit this frost and either become noisy or stop altogether. Locating the defrost timer can be tricky....they are often hidden behind the back bottom corners of the fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some are behind the cold control cover. Once you locate the defrost timer, slowly turn the screw likeknob in the middle of the defrost timer with a straight screwdriver until the fridge shuts off. You are now in defrost. If the defrost heater (s) comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not come on, you can continuity test the defrost heater for continuity or test for 120 volts to the heater(s). If you have no power to the defrost heater (s) you can also bypass the defrost thermostat to see if the defrost heater will come on, jumper the wires together to bypass the defrost thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat. If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater (s) and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.

Once you locate the defrost timer, slowly turn the screw like wheel in the middle of the defrost timer with a straight screwdriver until the fridge shuts off. You are now in defrost. If the defrost heater(s) comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not come on, you can ohm test the defrost heater for continuity or volt test for 120 volts to the heater(s). If you have no power to the defrost heater(s) you can also bypass the defrost thermostat to see if the defrost heater will come on, join the 2 wires together to bypass the defrost thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat. If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater* and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.

*One new safety device added to refrigerators in the last few years has been a in-line fuse added to both sides of the defrost heater. If one of these fuses let's go, you must replace the whole defrost heater, as it comes as an assembly. If the defrost heater does not work, you should check for one of these fuses being open. Check it with a volt meter or ohm meter.
On a frost free refrigerator, the cooling coils should be in the freezer section. On a SxS style refrigerator the coils will be behind a cover on the back wall. On a freezer on top style the coils could be behind the back wall or under the freezer floor. Removing the cover and exposing the evaporator coils could be a valuable tool. Seeing what the cooling coils looks like may help split your not cooling problem. Totally covered coils with white snow is a frost free problem. and the rest are bare is an indication of a system problem. System problems may be a leak in the refrigeration tubing, an inefficient not 100% pumping compressor.

Good luck

Nine y/o GE side by side not getting cold enough


More likely a defrost heater. Look inside the freezer at the back wall. Any frost there? If so, turn off refrig., unload freezer, take back panel off inside freezer, and use a hair dryer to melt off the frost. Replace the defrost heater located at the bottom of the frosted coils. (New heater may appear different than original, but instructions are included) If you don't have the defrost heater on hand, just manually defrosting the coils and re-starting the refrig will get is cooling again for at least a week before problem will re-occur. (this give you enough time to get the replacement part)

If you can locate the defrost timer and advance it to the defrost cycle you should be able to see the defrost elements glow behind the rear panel in the freezer. Do this before the freezer gets too frosted up. If you can't see the glow then there is a problem with the defrost heaters or the defrost thermostat. Unplug the frig and remove all the racks in the freezer. Remove the screws holding the rear panel on. Locate the two heaters and check the resistance. IF open, replace heaters. IF ok check resistance of the defrost thermostat. IF open when cold, replace defrost thermostat.
If replacing heaters always replace defrost thermostat at the same time. It will save you doing so at a later date

What if both sides of the refrigerator is not getting cold?And the back of the freezer side has frost.


Defrost problem. Either the defrost thermostat, defrost heater or defrost control board needs replacement. The defrost heater has to have continuity. The defrost thermostat has to have about 0 Ohms while it's cold. If both test out ok - replace defrost control board.
Part locations: Defrost heater and thermostat: under your frosted cover; control board - left upper corner of fresh food section, under the damper cover, in the middle.
Part numbers:
240554502 - control board
5303918255 - defrost heater kit
Can't find the part number for the defrost thermostat

Frost free fridge freezing up

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.

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.

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.

Would also appreciate if you could provide us the model number of your fridge so that if the above solution does not resolve your issue would look into the matter specific to your type of model.

I am sure this solution would help you to resolve the issue.
