Ok so got tired of battery operated refrigerator air circulator. Orered some 12 volt fans from amazon. Installed on behind light, got power from hot side of light switch. This stays hot as long as refer is on. And with door shut.
Also added on on lower side of vent to blow up to factory fan at upper vent. Powered that fan by adding a switch. Will only use when outside temps are high. So by option.
Then realized that upper Fan was not coming on. Found faulty limit. Will order and install later. But that created a problem. How to fasten factory blocker after removing. That plate is installed before refer is installed. So removed it and figured I would get it fastened and sealed after the fact.
Well that was easy, there are unused holes in frame of dometic housing see picture. Perfect mod to gain access to a lot more of the fridge.
