I have a 140 litre front opening Waeco fridge inbuilt in my Transit van. Would it be of any benefit to install a second fan at the rear to assist in the movement of air past the back of the fridge. I mentioned it to a caravan guy who said in his opinion not worth it for a compressor fridge. Has anyone done it and noted an increase in performance (less cycling) in their fridge

My CR110 Waeco upright fridge has a fan as standard, but how much cooling it really does is questionable.
A big fan would only do some good, but at what cost to battery drain ?

These upright fridges are very inefficient, so apart from parking in the shade and not opening them very often, the only solution is to have enough battery supply to keep them going.

The heat must get away from the compressor/condenser. If it is not ventilated well enough to do that, a fan will certainly help. I run extra fans on the OKA fridges. They are connected via a 50C thermal switch mounted on the compressor, so only run when they need to.
If you want to significantly reduce the power consumption, increase the insulation all around the cabinet. That applies to any fridge.

Yeh, one thing I've been thinking of doing to mine. Probably only enough room for approx 20mm thick insulation, but finding something suitable that can be glued to existing insulation is the problem.

The best insulation is closed cell polyurethane foam (brown stuff), just like as used in almost all fridges. It can be purchased in sheets.
It is almost twice as good as polystyrene the same thickness.

An exhaust fan in the roof of the vehicle would also help to let some of the heat escape. On the roof of my alloy ute canopy I fitted a solar powered exhaust vent and a vent up near the fridge so the air can be drawn in near it every bit helps.
