New TT, New Fridge - Is the venting ok?

Just bought a Starcraft 18BH. It comes with a Norcold N306R. It is vented out the side of the trailer.

Wife noticed the Countertop above the fridge gets quite warm so I opened up the vent to have a look. There is a 45 degree baffle setup to direct heat out the vent. That said the baffle is loose fitted, with gaps around it.

Any thoughts if I were to use some silver reflective tape to seal things up? This is my first TT so I am not sure how it should look in here. I would think in my little reading that the more heat I can get out the better the fridge will work. That said the fridge is working well so far without any issues.

Also any benefit to adding a fan in here to push the hot air out? Maybe I am just over thinking things. If the fridge is working fine, maybe I should just leave well enough alone...

Thoughts?

Many thanks in advance!

  • Consider yourself lucky. Many don't have this 45 deg baffle, including our unit.

    FWIW, ours came from the factory with quite a bit of insulation installed between the frig and surrounding cabinet (sides & top).

    We installed two, 3-speed computer fans in the top cavity opening to pull air out. Leave them on 24/7 (speed on med). Both fans only draw about .4 amps total (12v). When ambient temps get above 90-95 deg these fans significantly improve the frig's cooling ability (8-10 degree drop--low 40's to low 30's).

    Excellent idea!
  • Foil tape it up and install a fan kit. Anything to help with the heat. The frig will thank you.
  • Dead air space is a killer when it comes to proper air flow and fridge cooling.

    The baffle is a good start at helping to direct the air flow up/out but the gaps around baffle aren't helping.

    Remove baffle..

    IF nothing else.............SEAL the edges of baffle
  • If we were meant to leave well enough alone, The Wright Brothers would have been content to just have a nice day at the beach flying a kite!

    If Newton didn't overthink things, we wouldn't have been able to set foot on the moon!

    Tinker away my fiend, tinker away! Its only human to do so.

    The insides of RVs get hot enough as it is, deterring a little more heat from entering would be a good thing. I would even go so far as to cover the whole baffle, especially if the baffle is just wood. It will reflect more radiant heat out toward the vent.

    And while I am over-thinking it. I would look into adding two or (if you have the room) three 12v computer fans blowing out of the vent to remove the heat. RV refrigerators work better with good ventilation. The side vented model don't create a good convection current and won't work as efficiently as they should. Adding the fans will help with that. Do a Google search to figure out the best placement for your set up.

    WARNING!!! Once you start tinkering you won't be able to stop. Its addicting! But, hey its only money! Have fun!!!

  • 1 for sealing it up, 1 for leave it be.. I should make it a poll ;-)
  • I would seal it up- it *will* work better. A bit of foil tape is all that's needed.
  • Maybe I am just over thinking things. If the fridge is working fine, maybe I should just leave well enough alone...

    Bingo!
