We’ve been having issues with our new TT Norcold refrigerator not keeping things cold, quit working and warming up.

What’s the best way to keep these cold, first off is making sure the TT is level?

Thank you in advance

You have been told multiple times in your other posts about this same issue.

YES, Level works best.

Absorbsion fridges use gravity to move the coolant inside the tubes, gravity only works best when the tubing is in the correct orientation.

Yes, it is possible to run a absorbsion fridge out of level, but by doing so you are not going to get full capacity operation.

Out of level operation can also starve the boiler tank which can lead to overheating of the solution inside the tubing.

Overheating the solution leads to the solution to break down, crystalize and block the smaller but important tubes leading to intermittent operation and finally a fully blocked system with no cooling at all.

Repeated out of level operation can and will damage your unit permanently.

Your goal is to setup your RV so the inside bottom or one of the shelving in the fridge indicates level. Measuring level anywhere else can be done but sometimes the fridge may not be plumb and level with the rest of the RV.

How to read a level?

Simple, the goal is to keep the little bubble inside the level between the center goal posts.



In the pix, you want the bubble to be in between the blue arrows.

If the bubble edge crosses outside of the blue arrows, you are now out of level.

Absorbsion fridges are also not very fast in cooling, may take up to 24 hrs to stabilize from start.

They are slow to recovery, open the door for a minute and may take several hrs to recover.

Load room temp items in it and it may take several hrs to recover.

Load entire fridge with room temp items and it may take 24 hrs to stabilize.

You also do not want to pack a RV fridge tight, doing so blocks the natural air flow inside the fridge resulting in uneven distribution of the cold air (remember, a RV fridge works on gravity and that includes the inside portion of the fridge).

Perhaps you might be better off switching to a compressor fridge and add a few

batteries?
