Question about Samsung RS2630SH Side by Side Refrigerator

1 Answer

Mullion between freezer and refrigerator is extremely hot.

The very front of the wall that separates the refrigerator and freezer is very hot to the touch. I am talking about the part that the rubber gaskets on the doors touch when you close it. I have been told that there is a "mullion heater" in most side by sides to make it seal better, but I don't think it should be that hot. Thanks, Jaye

    I have the same problem. My refrigerator front side wall that seperates the sides gets burning hot. The outside side of the freezer is burning hot too. When ice-cream put in the freezer touched the wall, it melts in the freezer. Got the motor and fan replaces, that did not solve the problem.

They rarely use 'heaters' anymore. If there is a heater there will be somthing like a 'energy saver' option to turn it off. More likely it is a mullion loop that is part of the sealed system tubing. The harder the frige works the hotter that area will be. So if the inside temp rises so will the temperature of the mullion. Start by checking your frige and freezer temperatures with a thermometer. The freezer should be between 5-10 deg ABOVE zero and the frige should be about 35 or 36 deg. Also check that the condenser is not dirty. The condenser is the coils that are usually underneath the frige. They should be cleaned at least annually. Also while you're under there make sure the condenser fan is running. You should feel a little air movement and possibly hear it running from the front under the doors. If it's not running you'll need to find out why, but would usually be a problem with the motor. Also there was a carboard panel on the back at the bottom of the frige from the factory, that panel HAS to be in place to direct air across the condenser and not back behind the frige.

    This area under the fridge was clean, no dust bunnies. Some water in tray but it was not full or overflowing. Any other suggestions?. Especially since the wall is split and cracking turning brown in some places.

The outside of the fridge gets extremely hot is that normal

If it is a Maytag or Whirlpool refrigerator, check the refrigerator light.

That thing hardly does anything except annoy people when it burns out.

It can get so hot in some refrigerators that it melts and warps the plastic shell of the refrigerator. It could be burning through the insulation of the fridge right before it shorts something out or starts a fire.

Refrigerators and fires should be opposites.

If the condenser coils are too close to the wall, the heat that is removed from the fridge circulates around the unit. The outside feels hot because there isn't enough air flow to dissipate it.

That sounds like the blast of hot air from the air conditioner vent when you are walking into a restaurant.

Your refrigerator is working on the exact same concept, but without a vent. If the refrigerator is right up against the wall and there's no air flow, the heat builds up around the fridge.

That probably hurts the refrigerator's energy efficiency, too.

Yes, it does.

I think there's plenty of space around the refrigerator, though.

You ought to clean the refrigerator condenser coils anyway. It will let heat escape from the coils more easily, so the unit won't have to work as hard or as long.

I wonder if the coils might be clogged like my AC's were, once.

They might be, though that would require calling in a repair person. Unless it is the mullion.

I have heard of million and mutton but not mullion. What is that?

The mullion is the narrow section between the freezer and fridge. It is sometimes warmed up to prevent sweating due to condensation as you keep opening the doors.

So that part is normally going to be warm.

But if any other part of the fridge is warm, that's not cool.

Mullion on ge monogram extremely hot and freezer is working fine and refrigerator appears to be ok. Have vacuumed the upper and lower sections and turned the energy saver switch on. Where to get manual and...

It's not abnormal for the condenser to get hot especially in the hot and humid weather we've been having. Usually atleast some of the condenser coils are welded to the inside of the sides of refrigerators and freezers. Depending on how hard the unit has to work to keep it's inside cold the outside gets hotter.
I hope this helps.

Ge zisw48dyb hot to touch on middle bar front between doors

Pull the refrig out and remove the lower panel . Check that the fan motor is working and no object is blocking the blade to keep it from turning . If your compressor is a top model , remove the top cover and check the fan motor and coils for dust coverage .

Middle frame between doors is very hot on whirlpool

Practically all refrigerators have what is called a "mullion heater" between the freezer and fresh food compartments. Otherwise, the wall separating the fresh food and freezer compartments would freeze as well as the fresh food compartment. Some heaters are a bit warmer than others according to brand of appliance.

Panel between fridge and freezer very hot and no sound at all

Hi: Its just a coincidence you noticed it then. It is usually hot. It's the reverse side of the refrigerant (the hot side.) If you lived in a humid area the fridge would sweat. Water would run down between the doors. I live in a dry climate so no worries. Older fridges used an electric heating element to keep them dry. They also had an energy saver switch to turn it off. As Whirlpool uses the hot side of the refrigerant they don't use additional power to run the heater. Actually the heater is called a mullion heater. Nothing is wrong with your fridge. I'll look over my shoulder for angry retailers. Hope this helps, Jeff.

Freezer working but refigerator not...

Mullion heater is not the problem. If the refrigerator is not cooling look to the freezer compartment for your problem. Air from the freezer is used to cool the refrigerator(s) section. If the freezer coil frosts up it stops air circulation to the rest of the system. Although you may think the freezer is working properly it may have a defrost problem and will show up there also. Look for signs of frost on the back wall of the freezer as a sign of the coil freezing. The mullion heater is designed to put out just enough heat to stop condensation between the outside temperatures and the inner compartmant temperatures. If the inner compartment is warm the heater will seem warmer than normal.

Side by side Kenmore fridge

These areas are where the thermal break is made between the inside and outside temperatures to prevent humidity from condensing on the surfaces. They are called mullion heaters. If you have an energy saver switch turn it on and it will reduce the heating effect. If the temperatures on the inside of the refrigerator and freezer are elevated this will be noticed more so.
