What Exactly Is "Moist Cool" Anyway?

[combo52]

Ideal ref temps

No part of any refrigerator designed to preserve food should EVER be at 40F or above, we call that broken and in need of immediate service.

 

People who work in food service will tell you that you either keep food below 40F or above 140F.

My fresh food section is set at 35°F, freezer section at -2°F.

The meat drawer is a Custom Cool drawer that has:
- a timed defrost function (1/2 LB = 4 hrs, 1 LB = 6 hrs, 2 LBS = 10 hrs, 3 LBS = 12 hrs) (use it often)
- timed Quick Chill function (15, 30, 45 mins) (have never used it)
- specific temp settings for Citrus (43°F), Produce (35°F) and Meat (30°F).

Basicly any packaged food over here says "Store at 7C or below". So there's that.

GE Breaks Down Various Condenser Types

Personally have always heard condensers located on bottom of fridge were hard to keep clean. Especially in homes that were dusty and or had pets. Can imagine all that hair and dust just gets sucked into condenser rather like air conditioners.

GE Serpentine Coil Boxes

I believe I was told that there was a thermostat mounted to the serpentine coil and the compressor ran until that coil's temperature read -20F. A surface that cold pulled a lot of moisture out of the air in the fresh food section. As the frost on the coil melted, it went from a solid to a liquid state so it did not return much moisture to the environment of the fresh food section.

Anyone have a photo of GE's claimed "Neverclean" design?  How does the heat dissipate (presumably meaning without a fan) if it's "located in the compressor housing instead of on back?"  Does that mean the condenser is physically part of the compressor, not a separate coil structure?

No, the GE never clean

is a jelly roll condensor. I don't know abot the dual evap. cooling models, with a seperate fridge section evaporator coil. I vacuum mine twice yearly. It doesn't get nearly as dusty as the flat serpentine style.

 

[DADoES]

 
OK, that's what I figured.

Neverclean is complete marketing bullsh!t.

This is mine today.  The non-fan side of the coil roll is closed with a cardboard cover.  The fan pulls air in through the coil roll from the left side of the front toekick and/or the rear cover (which is slotted at the coil side, solid at the compressor side) and blows it across the compressor and out the right side of the toekick.  It was cleaned by blowing with an air compressor not more than a year ago.  There's no way vacuuming can reach the full surface, around the backside.

It's a 16yo Arctica SxS, dual-evaporator.  One (variable speed) compressor with a valve to direct the refrigerant to either or both of the evaporators.

My 14 cu ft Kenmore chest freezer gets away from the dusty coil problem. The heat emitting coils are all hidden behind the outer surface of the chest. Seems to work just fine, and never needs dusting.

That's the typical design for chest freezers.

GEs Never Clean Condensers

You are correct Glen it is sort of BS. I did see a demonstration where GE wrapped an inch of fiberglass around the condenser and it does not affect refrigerator performance at all.

 

That condenser has to get real dirty to affect anything because of the positive flow of air being pulled through it. 

 

Even as dusty as that condenser is you could easily go 5 years before cleaning it if your home stays below 80F.

 

 

Shell Condensers On Chest Freezers [ these are also used on many all refrigerators and upright feeders as well.

 

SC have several advantages and several disadvantages.

 

They are cheap to build

 

They help to keep the cabinet from sweeting on the outside.  

 

They don't need cleaning.

 

The disadvantages 

 

They heat up the outside of the appliance so it is like your R or F is always operating in an 80-120F room which makes it run more and use more power.

 

You can not build it in tightly.

The current accumulation isn't significant regards to operation, but it's not like nothing is there at all.  It had more the first time I opened it in 2010 (it's a 2004 model) to replace the motherboard.  I've cleaned it on a recurring basis (yearly+) since then.

 

[launderess]

Is this what you guys are going on about?

The other awful thing about condensers hidden in the shell of the appliance is that if the condenser develops a leak, there is little chance of fixing it.

 

[gizmo]

condensers hidden in the cabinet

if a leak develops, I have seen them retro-fitted with an old fashioned black tube condenser on the back of the cabinet. However you do lose the hot gas heating around the door openings to prevent condensation. Probably doesn't help efficiency, either.

Add-On Condensers

Reply #44, Actually it would improve efficiency quite a bit, this is why all the biggest and best refs use a fan forced condenser.

 

When you look at the huge refs we build in this country that have large capacities and all kinds of features and they use as little or less power than an average chest freezer, the fan forced condenser is one of the reasons for this amazing efficiency.

 

Condenser fan motors generally draw 4 watts or less now a days.

Admiral SxS is now into

its third year and I still have not had to clean underneath it. I have pulled the grille off the front and cannot see what needs a vacuum? Its just had another repair the same board that went last year decided it would not let the thing work with the door shut !!! It worked ok if you open either door it was deemed a relay on the board had died so I bought a cheap Beko fridge freezer that works on the wet back wall system, The freezer part is frost free and boy did that get cold quick the fridge took a few hours to get cold but it remained cold what I found odd was it was so quiet am not used to that kept thinking it wasn't working.
So now have a bottom freezer/fridge to get rid of as no room for the 2 its down the shed at present out the way.
OK so todays daft question what should I be looking for on this Admiral fridge that needs cleaning ?? I had a Whirlpool before this and the dogs would lie in front of it where the warm air came out sadly their fur made its way into the coils underneath and what a bugger they were to clean out? The photo shows how awkward it is to get at especially when your a bit a on the portly side lol.

Cold Wall Fridge?

Am trying to understand and do better with visuals. *LOL*

GE NeverClean condenser

Apparently aren't well loved nor liked by some repairmen or owners of refrigerators with system.

Kelvinator Moist Master

Brochure/owners manual for 1941 Kelvinator "Moist Master" explains things rather well IMHO.
