BrunnerDouble fridge fan Electr.

Added them in top fridge/freezer vent on a caravan. Helps to expel warm air to outside. Working well so far. Good product, easy to fit, manual or auto operation settings. Makes fridge/freezer a lot more stable in this hot weather.

Great product for the price the second one I've purchased would definitely recommend, easy to install

Motorhome fridge wasn't coping in hotter weather so needed fan assistance to circulate air past the fridge coli things and out of the grilles rather than just hoping for convection. When on there is slight background noise from spinning fans, but not obtrusive. There is manual setting when it runs full tilt, or auto where a temperature sensor in the fan mount will run at moderate or full tilt speed depending on the temp. It won't switch off fully by itself if temps drop say overnight that fan isn't needed, but switch allows you to select off and then it simply has a LED showing power is connected. Max power use is apparently 6W at 12V. Temps to the fridge did drop so short term at least this works, but have only had a few days so can't speak for long term reliability.Fitting is a bit of a challenge. The positive and negative power connection wires which come from the switch box are only 200mm or so long. They are very thin. You will need your own 12V 5A cable to get to and from where ever you can tap into a 12V supply to your fridge (if you don't have a wiring diagram of your vehicle, get a multimeter), and then connectors at your tap in point and also to make to the fan switch end. Also recommended you have an in line 5A fuse on the positive connection. Lead between the switch and fan is less than a metre length, and has at least three cables, but has a plug connector (looks like something you'd find on headphones) mid length so you can at least push the cable through from your fan mounted by a vent grill on the van side, and to your switch position which you'd have near the fridge.

This is a decent product but with some annoying features. Fan size is 80 cm which presumably is sufficent as I haven't had to chance to test it properly yet. However, fitting is made more difficult because the cable between the controller and fans has a jack-plug connection which requires a 10mm hole in whatever it passes through. The 12v supply wires are very thin and very short so joining is almost essential, but made more difficult by the very narrow gauge wire. There is a hole in the controller box where you are supposed to be able to adjust the temperature but the only screwdriver I have which fitted (a very small phillips type) appeared to contact nothing as no resistance could be felt. The hole is so small it is impossible to see what is in there. I took the back off and turned it around as the two cables exit from different holes and rerouted the fan cable so that both came out of thesame hole. The pcb is not only screwed into the case but there is also a seal of some kind, so I was unable to see the front where the temperature adjustment screw is supposed to be. The instructions are poor and fairly brief so I emailed Brunner for further info but they simply referred me to the dealer! As that is Amazon, then no chance of contacting anybody to get help. The fan kit appeared to come from somewhere in France according to the tracking information. The fans work OK on manual, so I may just stick with that and ignore the auto setting.

Bought these to add cooling to the fridge on my caravan! So far it’s doing a great job, unfortunately I can’t tell if the sensor is working as the fans are going all the time. I will need to wait until end of season when I remove the awning.

Had these in my last four caravans. Still as good as ever but easier to fit now with the plug on the control box. Just make sure you turn it off before you connect or disconnect.Like all these add-ons that the caravan manufacturers should put as standard (Coachman 2018 VIP, caravan door when open covers fridge vents, Dohh!) you may have to epoxy glue a bit of wood inside to mount the fans on but took me 45 minutes to fit and power up all good.After fitting I realised I could have just mounted with a couple of "Mecanno" type metal corner braces

Easy to installReally helps out with fridge cooling on the caravan

Only just fitted and tried once, seems to work ok, time will tell!
