it's cheaply made. Arrived broken, but fixable. As someone else mentioned, the wires are incredibly small gauge. Doesn't fit within a side mounted vent. Doesn't include a fuse even though the instructions say you need to have one.

hey include a temperature controlled switch which is affixed to the fan (older versions had them separate from the fan), but one of the install options is to place it below the refigerator, blowing upward....problem is, that location doesn't get hot and therefore the fan would never turn on....so the temp controlled switch would need to be removed and installed somewhere else.

The included on/off switch doesn't have good mounting options.

I'll give it two stars because it can be used in some situations, but anyone with a tiny bit of skill can make something better for cheaper. Just get an appropriate sized fan (muffin fan is perfect) and a temperature controlled switch.

Freezer worked but couldn't keep refrigerator cold enough in hot weather. My husband was ready to buy a new 4 door refrigerator/freezer for our 2006 motorhome at the cost of at least $3000.00! I convinced him to at least try adding this extra fan after reading several reviews. IT WORKS!!! IT WORKS GREAT!!! Not the easiest to install for someone 78 years old, (he installed it on top of the motorhome), but definitely worth the effort. We've used it now for 2 months with outside temperatures as hot as 114 degrees! Don't let the RV repair people try to convince you that you need to replace your refrigerator just because it's old. This is a cheap, MUCH CHEAPER, fix!

I haven't used the unit enough to really rate it, four stars because of a fault in probably the assembly of the unit. Instructions don't give any indication of the direction of the air flow. I asked on the question site which way the motor turns, and was told clockwise. Clockwise rotation blows air DOWN.
I hooked the motor up to a 12v battery, heated the thermostat with a hair dryer, and lo and behold it blows air down. Doesn't make any difference if you turn the unit over. I corrected the problem by switching the ground and the positive wire feed to the motor, and it seems to work like it should. Looks like another indication of poor quality control in a foreign-made product.

This thing really works to keep the RV fridge cool. Without a fan the fridge depends on air flow over the coils by convection. That works fine in cooler weather but in hot weather not enough air moves over the coils to keep the fridge from getting too warm. I read somewhere that some RV manufacturers are putting in vent fans on the fridge because of this problem. Anyway, the quality of this this is fair. When I unpacked the fan the motor had popped out of its mount and I had a hard time getting the motor back in without damaging it. The motor and fan blades are very lightweight and easily damaged if you aren't careful. So I got it back into place partially, enough that I think it will stay after being glued in. Mounting it was relatively easy. I wanted it mounted on top at the roof fridge vent which meant I had to break the seal on the vent and take all that (2 pieces) off. Then, instead of using the metal brackets provided I added two small pieces of wood and mounted the fan housing to that. I left room to add a second fan if I felt it was needed in the future. So re-installed the roof vent and cover (you will need the correct caulk and sealant) and connected it to the 12-volt supply. The fan has a thermostat switch which comes on when the temperature reaches about 82 degrees. So I wanted to be able to manually turn the vent fan on if I wanted, I was thinking I might need to keep it running and certainly didn't want to uninstall all that just to get another hot wire to the fan. (As it turns out all that work was not needed, it has worked fine off the thermostat). so I soldered an extra lead before the thermostat directly to the fan motor and ran both wires down into the fridge compartment. Then I ran both to the 12-volt supply so that the fan could operate from the thermostat or by manual operation (which I haven't needed to do). This really helped our RV fridge stay cooler, these things don't really cool very well ever so they need all the help they can get. When the fan is running I can hear it inside the RV but it's mostly because I know what it is and it's not noisy, I think that if I didn't know what it was I would never notice it at all. In hindsight I think I could have mounted the fan housing on some rubber grommets to lessen the sound even more but I don't think that's really needed. I have heard of people installing the fan at the bottom of the fridge compartment but, even though it was a bit more work, I thought the top mount would be more efficient in moving air. I was pleased with the improvement of the fridge and the installation wasn't that big a deal, it's worth the work. I would highly recommend this to improve the operation of any RV fridge.

I have struggled for a long time trying to get my RV refrigerator to cool better and replaced almost everything but the box. This fan made a huge improvement of 4-5 degrees after instilling it in the top vent.When it gets in the mid 90's to 100s my unit just was not doing well and I worried about food safety on trips. My Kountry Star refrigerator has never cooled as good as past campers and I learned the poor air flow to the top was the problem. There are several videos online showing installation but the latest fan now has the thermal switch built in the fan making one less step. For best results this fan should be installed in the top, pulling hot air out! I removed my refrigerator to improve the ducting and flow by installing some curved flashing near the roof top chimney vent. This made installing the fan simpler also since I used a screwdriver to open a gap in the roof sealant and twist in the fan from the inside and not having to remove--reinstall the roof vent. Some silicone was used to make sure it stayed put. This could also be installed, I assume, by cutting the screen on the vent, then installing from the top but most people remove the vent, place the fan, apply proper sealant, reinstall the vent flashing and then reseal the attachment screw heads. I didn't want to risk damaging the parts on the roof or compromise the factory seal since there are other ways.The best way to verify this fan will improve your situation is to remove the cover from your top vent and place a small fan on top sucking air out and recheck it after waiting at least 12 hours. A remote temp prob or a thermometer should be placed in a cup of water on the middle rack to get the best reading. You may also unplug the thermister wire from the circuit board, or remove the thermister from the fins and let it hang to make sure your unit is cooling at max capacity. Be sure and test each change one step at a time waiting 10-12 hours between test. I would recommend using online resources to check other options first and get you unit working as well as possible first but this fan will help in any situation. I think a roof fan should come with every installation but We all know how things are these days. Thanks for reading,,DS
