I have a RB215LABP/XAA the freezer will not freeze, lowest temp is 41 deg. The fridge works good, but builds up a lot of water under the crisper then freezes. this unit is about 3-4 yrs old. I bought the extended warranty, and Lowes sent me to a local repair shop and he came out looked at the fridge and said the defrost board is out. they then called back and said no parts available for this model and set me a pro rated check about 450.00 less than the ripoff price. Any how, the only control board is in the back, does this single board control the freezer/fridge? if so will this cause my problem or is it a bad sensor? Oh, the freezer will ice up in the back but only at the vent ports. any help would be appreciated.

hi there this is a common fault you need to replace the evaporator cover with the new modified one which has a large heat sink around the fan to stop iceing up also you will need to replace the thermal fuse and the defrost sensor.

hope this is of some help

You have to pull out the sensor from the board and test with tester, both sensor should read the resistance of 10,000 to 20,000 ohms. The reading that you show is very low it means that the thermistor is out of range and need replacement.

the ice maker wont cycle untill the temp of the ice is around 10 degrees so if the freezer is at 15 or 20 due to some other malfunction then you will see the maker full of ice but it wont harvest and make another batch. so you could have a sensor bad, control malfunction, refrigeration issue, compressor, defrost system malfunction(you mentioned ice build up)

SOURCE: Side by side refrigerator freezing up

inside the fridge there is a cold radiator which has filled with condensation or water from freezing it when say cleaned out the fridge this can be remedied by letting set for a few days outside in the sun so that water can evaporate properly or you can call a repair man and he can pull out frost radiator inside and defrost all the water out by dry wet vac and heater dryer

ice builds apon ice even a little bit can build up to a mountain same thing happended to my top end whirlpool i pulled the metal grate and defrosted this by pouring tap water over the ice which it went down the defrost tube outside water drain this helped greatly havent had trouble with ice since

SOURCE: fridge condensation - freezer thawing

OK now I'm wondering are theses numbers your getting 4 -9 the actual temps of the refrigerator and the freezer? and do they feel this cold and correct to you? I know the refrigerator side shouldn't be below 34 or so and definitely not below 32. If this is correct and the numbers are not settings but temps. (Now if you have a touch pad its electronic. If it has knobs it has a separate defrost and thermostat and are electro-mechanical)
If electronic Your control board and possibly defrost control are out.
It would more likely be the sensors going to the board(s) It will both sensors have the possibility of causing your problem. 1 will control the run of the compressor (and this one could and probably is connected to the inside coil) and 1 will control the air damper tween the refdg and freezer compartments, and may turn on the inside fan operation too.

(this would be my first suspect if these are degrees numbers). Look at the thermostat control see if it is attached to the indoor coil (usually the tube leavign the indoor section. If its not attached its not sensing the coil temp and when goes into defrost wala its not senmsing temps like its designed to do. Look for a broken clip or possible a plastic wire tie that holds this sensor in place.

Please get back to me with what you see - find on this look up.
