Posted for Cummins12V98,

Thank you Barney for posting these pics!

I noticed when I looked at the pics I needed to add insulation between the fans. Those two fans are what came on the rv. I installed the single one with a switch in the lower compartment. I aligned the single fan behind the upper vent slot in the access door and as close to it as possible.

For now I am running the single fan all the time and have the double fans still tied into the controll board. The daytime temps have been in the low 70's and the frig has been steady at 40 degrees on #3 but the freezer is colder than before with the ice getting very hard. So just the one fan pulling air thru the back side of the frig really makes the frig work better.

I have a constant hot wire and inline fuse that I can use for the two fans when it gets really hot to plug the two fans into if the computer does not keep them running all the time.

I will report back when we get to SoCal this fall how it works with all three fans running with the temps 90-100 degrees.

It really helps to seal off the holes around the fans. The two fan pic is looking down from the top access/vent door. They are mounted mid way between the two access doors.

Thanks again Barney

Update!

With the temps in the 90's and the frig on 4 the frig temp has ranged from 36 to 38!

The factory fans have only come on when the temps are in the mid to upper 90's.

With the continuous fan running the temp has stayed at a steady 36 when the temps are in the 80's or lower.
