The refrigerator may need more coolant. The system should be checked for any leaks before adding the appropriate freon replacement. (I do not know if this is user servicable or if it has to be done in the shop.) Check your warranty for the item to see if this is covered.

Model # MFF2557HES Top refrigator section stoped cooling freezer is working


You may have Ice buildup in the freezer. You freezer has a fan in the bak that sends the cool air to the fridge. Your fridge dial determines how muh cold air comes from the freezer. Try defrosting the freezer. You may have to pull the back panel off of the inside of the freezer to get the ice thawed. The ice build up is likely causing the air to not get to the fridge. Hope it works.

Fridge warm, freezer has frost on back panel & is defrosting, fans work, just changed defrost thermostat, no air is moving from freezer side to fridge side, drain pan under fridge is dry


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

I have a sub zero side by side. The refrig side is at 40 degrees but a 10 inch by 6 inch piece of ice keeps forming on the left size, back wall. What would be the likely cause of the ice build up??


Hello,

Their are 2 possible things causing the ice build up

1) the condenser coils is very dusty and must be cleaned,to clean it remove the top grill and the smaller panel behind the grill,use a vacuum to clean all the dust from the coil

2) the evaperator coil in the refrig. behind the back wall has a small refregrant(freon) leak in it and the coil needs to be replaced

I hope thats its due to the upper coil needing to be vacuumed since its something you can do at no cost,but even if it doesnt fix the problem the coil needs to be cleaned to help both the freezer and fresh food section work more efficently
if after cleaning the upper (condenser) coil and turning off the fridge to melt is away ice build up from (evaperator)coil,if the ice ball reoccurs the repair could be as much a $1,000.00 to replace the coil and recharge the refrigerant

GE French Door 22 cu ft (PFSW2MIXSS). Loud buzzing from behind the freezer. Ceased cooling.


The model number you post appears to be incorrect.
The buzzing was from the evaporator fan blade hitting on some ice build up. Getting to it on a bottom freezer refrig is a bit of a pain in the back side. If your model has a pull out freezer drawer, that has to be removed, the icemaker removed, one side of the drawer supports from the freezer wall, all to allow you to remove the back wall of the freezer to get to the fan. You may be able to just thaw out the fan and surrounding area then which will get your refrig cooling again, if the ice was just around the fan area. On the pain in the but repair scale of 1 - 10, this one rates at least a 7.

Fridge on top of freezer is not chilling


if you have a french door (also known as bottom mount, freezer on bottom) and your fridge sections(cold air blows from freezer to refrig) is not cooling try this

1. ensure you hear the fan running, its it not, thats it(most likely fan motor
IF fan is running check these things
1. ensure refrig section light shuts off by holding down the switch
2. ensure door shuts
3. clean conderser coils (usually accessed from front through base grille)
4. check for icing in vents, freezer section contain them at top or back, and for a bottom mount the refrig sections vents are under your BIG drawer. if iced try a hair dryer from distance. or empty food into another fridge unplug open doors, and plug back in two days later this should defrost all ice build up
