I have a KitchenAid Refrigerator Model Number: KBFC42FTS. Bottom drawer freezer over cools -10 degrees.

For several weeks the bottom drawer freezer over cools -10 degrees several times a day, and the freezer makes a loud, on again-off again, humming noise. When the noise stops it means the freezer temperature has gone back to zero degrees. The refrigerator temperature is not effected and holds at 37 degrees.

That's interesting, -10 or colder is too cold and something is defiantly going on. This unit is controlled by a mulitple control boards, temperture sensors and other components. Question, what is freezer temp set at? Try increasing it by 3-4 degrees and see if that changes anything. Beyond that, I'm going to change the temp sensor first before doing any of the control boards. #29 is the temp. sensor. Good Luck

SOURCE: GE Profile Refrigerator (Model #20) w/freezer on the bottom

If the problem disappears (for a while) when the freezer reaches 32F, then I know what the problem is.

The GE Profile refrigerators (and likely other models as well) often don't defrost properly, especially in humid climates. So they can develop ice buildup internally, especially if the air vents at the back of the freezer are blocked by frozen food. Once that happens, that ice can interfere with the cold air circulation booster fan that runs when the freezer temperature is too warm. Then you get a LOUD buzzing noise from the fan blades, as they bang into the ice.

The immediate "solution" is to be sure nothing blocks the air vents, and then to melt the ice that interferes with the fan. You can turn the fridge off for a while (with the food removed so it doesn't spoil), and/or get a hair dryer and heat the inside back of the freezer, until the ice melts and falls away from the fan. (Just be careful not to block the nozzle of the hair dryer, or it may burn out from overheating!)

But the ultimate solution is to buy another refrigerator, one that is NOT a GE! And that makes me sad, because GE used to make GREAT refrigerators. My last GE refrigerator is nearly 20 years old, and still works well, and it does so QUIETLY.

SOURCE: Sears Bottom Freezer Refrigerator - Loud humming noise

That sound is usually your icemaker calling for water. you can turn off your icemaker by lifting the little arm on the icemaker. As the icemaker calls for water the valve will be activated and will hum. This sound is usually not very loud. If your valve is making that much noise you may consider replacing the valve. The part number for you water inlet valve is #2315533 The retail price is $60.18 . I do have these on hand and available to ship out today if you need one. Please just let me know. You may also consider replacing your filter if your refrigerator has one. Thanks and I hope this will fixYa

SOURCE: Maytag Performa Bottom Freezer refrigerator making weird noises

This can be due to low supply voltage, causing the compressor thermal overload to trip out. Therefore when this happens the compressor gets hot and it keeps trying to start but fails. It can also be a faulty starter relay, which is located in the conncetion box of the compressor and is very simple to replace.

Hi you need to replace the main motherboard, depending on the age you should call GE if they service your area they will discount the cost of the repair if it qualifies and its cheaper than doing it yourself, if it doesnt qualify then the board usually is around $175.00 just to buy not including to install if you have it installed, this needs to be done quickly prolonged use with bad motherboard on this model will damage sealed system, ruining the entire refrigerator. If you need further assistance let me know.

I have a KitchenAid Refrigerator Model Number: KBFC42FTS. Bottom drawer freezer over cools -10 degrees.

Does that unit have a low temperature monitor built in? Maybe that is what is making the noise when your temps dip to -10 degrees. Actually, that is great because the lower the temps the longer you can keep food in the freezer so I would not be overly concerned about that aspect. BTW, have you tried to isolate the source of the humming noise?

Could be a number of things, low Freon, defective defrost timer. Suggest have a tech check it.
