So, tomorrow morning, if the fridge part is still warm, the way I see it there are only three ways to go at that point:
- Replace the "innards" (the cooling unit) or
- Try 'burping' the refer.
- Buy a new refer
Replacing the innards can run somewhere around $500, give or take (depends on your model). And burping is free.
The problem may be that there is a blockage somewhere in the refer's tubing. 'Burping' it means to first remove it from it's installed position, and turn it on the other three sides it has to see if you can somehow magically dislodge the blockage.
Here's one of the companies that will supply you with a brand new or re-built cooling unit. He also is a strong proponent of putting fans on/in your unit to get the max performance from it. RV Cooling Unit Warehouse
OK, it's on its bottom now, so turn it 90 degrees to the left, leave overnight, then turn it onto it's top, another overnight, turn it to its right side, another overnight wait, and you're done. Put it right side up again and re-connect and install it and see if it works better.
This method is somewhat controversial: some say it's pure baloney, others say they got years more out of their refer after doing it. The good thing is that it won't cost you a nickel to find out which is the case for you.
The amount of time you leave it on the other three sides is up to you, by the way. There's no hard and fast rule I have heard for that.
One more point: I would only do the change to a new cooling unit if your refer is in good condition. You know, no cracks, the door seal is OK, the exterior and interior look good. But if they are, replacing the cooling unit isn't hard to do, and will give you "as-new" performance.
Let us know how you make out if you try that?
