Baffle for Slide out Fridge

Hi guys, my fridge in the slide out (norcold) works as sauna in summer. I have overall 7 fans inside distributed in the lower, middle and upper and still works very bad in summer.

After checking the upper compartment I believe proper baffles will increase its efficiency (I hope so)

The question is shall I block all the air (marked in red) so that it goes only under the fins or the air coming required to cool off the pipe marked in red?

Thanks in advance

Once ambient temp is above 100f an RV fridge just doesn't function .

But check your fridge for the clearances , as per Norcold manual installation instructions.
You should find a diagram like this .

EDIT : It appears your RV manufacturer didn't block the hot air coming up the back of the fridge from circulating across the top of the unit .

As 'Skip426' has pointed out.........you have a DEAD AIR space on top/above the fridge

Draft (airflow) should flow up from lower vent, across/thru the absorber tube bundle and the across the condenser FINs at top and then DIRECTLY OUT the upper vent as shown in the diagram posted above

There is an installation manual for your specific model........
Download it and install baffles/diverters etc as needed to correct the RV MFGs improper installation

Thanks it’s clear that I need to install baffles on top but wasn’t sure about the right side of the fins marked in red. The diagram doesn’t show the sides

I will check the manual, you will notice my fins are not extending the whole side space and it’s only 3/4 of the area. Where the rest area on the right is empty with just the pipe (marked in red and green)

I was wondering what’s the best to deal with this area?
1. Keep it void so the air hits the pipe to cool it
2. Close the whole right void and making the air only travels through the fins

Install the Baffle above top of fridge to close off that dead air space

That will greatly improve cooling cause draft will flow thru Condenser FINS and OUT the upper vent vs being stagnant in that open area on top of fridge

Enclosing the condenser fins is NOT necessary....heat from flue flows up/out that space
Closing off the Dead Air space IS



What Model is your Firdge?

Despite installing 10 fans (pair on the lower and upper vent covers, pair installed on bottom area to push air up, factory pair in the middle to push air up) and with aluminum shields to block the voids in the upper compartment my fridge is still not cooling properly in summer!

More is not always better..........

Fans Pull air better then Push air

Try just the OEM fans in center and top fans only
No bottom fans
