Fan fix current draw?

Can anyone with this warranty fix measure or read the amp draw from the fan/fans. Is it one or two fans? I had an issue with refrigerator temps as well during my last trip out. Refer and freezer are by far my largest power drains. Have 400 watts of solar but have not increased storage capacity yet, so one day without sun and I need to use engine or generator.

I'm wondering if these posters ever got their issues sorted out with those fridges. I thought of this thread again today because (long story omitted) I've had to use our Interstate locally even though it's mid-July and on track to be Houston's hottest average-temp July in recorded history (mostly because overnight temps are not dropping to anywhere near normal values).

Typically I do not have to run my much-maligned propane fridge in Houston in July, but this is what it looked like at noon today. We installed our own thermometer which is why you see it penetrating the faceplate printing here (there was no other installation space available). I didn't want to have to open our fridge just to see the temp... kinda defeats the purpose. So the lead extends inside and the digital read-out is on the outside.

As an adjunct, you can also see that with the addition of Reflectix as well as the HeatShield commercial cab window coverings and the solar system which allows me to crank the Fantastic without limitation, my inside temp is 97 - just four degrees above ambient. Last year before I had the solar or the extra reflective material, my inside temp would consistently be around 107 degrees in similar conditions.

I suspect that the solar panels themselves are actually responsible for a bit of that gain because they stop a big patch of incident energy from hitting the roof directly.

Re: 2015 Interstate GT.

I recently tested my refrigerator (in my driveway) after having the fan kit and ventilation upgrade installed. The refrigerator was empty and the controller was set on #6. Temperatures inside the RV ranged from about 70 to about 95 as the day progressed. Temperature of the air coming out of the new vent was around 110 when the RV interior was 95. In in the mornings the refrigerator temperature was 30-35. In the afternoon the refrigerator temperature rose to around 50-55 with the RV interior temperature at about 95. Normally I would have used the air conditioner to bring the inside RV temperature down to am more livable 75-80. I believe my refrigerator will keep a temperature of around 40 if I do my part in keeping the RV interior at a more livable temperature. Note: the refrigerator is using inside RV air to cool the heat exchanger. Using 95 degree air does not leave much for the heat exchanger to use.

Also the refrigerator was empty which is asking a lot from the refrigerator to keep a proper temperature. Filling the refrigerator with food etc. will provide a large heat sink to maintain stable/cooler refrigerator temperatures if the RV interior ranged from cool to hot while you were on a day trip and left the coach AC off.

On a related topic, I read that some Interstate owners are experiencing problems with their freezers; they cool on AC but don't seem to work on DC (e.g., while driving). I had the same problem and the dealer mechanic discovered that the DC electric cables were not hooked up. Once the DC cables were hooked up, the freezer works fine on AC and DC.

I'm getting the mod as we speak in ft worth. It's 93 here and 102 in midland where I live. I'm so anxious to see if this works.

Actually all the condenser has to do is just that, convert the high temp. gas into a high temp. liquid which goes to the evaporator and expands to a low pressure gas absorbing heat in the process. As long as it does that, the frig should cool to setpoint.

Your residential A/C works w/ hi amb temps outside.

I had the mod performed in ft worth last week. Still won't cool below 46 f when coach temp above 85. With the ac running and coach temp at 75 f the fridge will cool to 36f on max cool setting. I pulled fridge out of enclosure to test and it worked fine. I relocated the fan to point up at around 120 degrees to help airflow. Currently waiting on 1500 ohm resistor to speed up compressor. Currently they installed a 500 ohm resistor with the current mod. Additionally I lined the enclosure with reflectix to improve aerodynamics a bit. In getting closer and hoping that the higher resistor does the trick.

I made these additional mods to improve cooling efficiency of the nova kool 3102

I don't know how many ohm's my new resistor has, but am looking forward to hearing if the 1500 ohm resistor does anything as I still am having problems with my refrigerator not cooling.

Appreciate everyone's comments. I just returned from a trip at Cane Creek State Park in southeast Arkansas. Day temps were in mid-90's and fridge could not keep temp below 43 or 44 and this was with a "blue freezer" pack in the bottom to help with the cooling and the dial set all way to 7. I will be calling the dealer today and see about getting the kit. My unit is a 2015 Grand Tour.

Keep in mind, I've had the mod and it did not help. You might let them know that . I'm waiting on a 1500 ohm resistor to speed up the compressor. The original mod uses a 500 ohm . I hope it works,

I not only have the kit, and a new refrigerator and new resistors and my refrigerator still does not cool

Southjk, could you provide more details on your fridge mod? Materials and procedures, for instance?

Thanks

Refer not maintaining temp.

After installing many Danfoss-based marine refrigeration units into Airstreams ( and many SOBs too), I have never had a client experience the problems that have been brought to light in this and other threads.

A properly installed and operating unit should be capable of cooling to the mid 30's with no issues, regardless of the ambient temperatures!!!!!

As far as the Rube Goldberg ( hope you all know who HE was!!!) solutions to your problems, I firmly believe that your dealers and Airstream are grasping at straws.

If you ask the equipment manufacturer ( which is where your operational complaints should be addressed), they would certainly tell you that the addition of these resistors to effectively speed up the compressor is not only discouraged, but will void the warranty on your fridge!!!!

I have seen this with other 'unauthorized hacks' of new components; mainly with roof A/C units and the specific use of larger start capacitors to 'help out' in high temp/humidity environments. Don't think for a second that hacking the fridge system design is a good thing, especially after the manufacturer spent considerable time and expense designing and testing these units prior to offering them for sale.

I would definitely involve Tundra or who ever makes these units to get their take on your non-cooling problems!! Any other solution is one of throwing nonsense (not the actual word I had in mind) against a wall to see what sticks!!!!!

PS: I don't use Tundra units, as I have found the quality and reliability of others to be superior!!

Obviously something needs to be done to remove more heat from the condenser. If the air flow is not somehow vented to the outside, I think it's a lost cause. Bottom line is in order to remove heat from the frig/freezer, that heat has to be moved somewhere, preferably outside. Otherwise you are just moving the heat from the frig and putting it in the cabinetry. Bigger fans won't help if they can't exhaust the heat from the condenser outside.
