A blower is different from a fan because a blower has a "squirrel cage" rather than a fan-blade. The blower is quieter, uses less amperage, and produces more pressure than a fan. Thus, blowers are better suited for improving the efficiency of your cooling unit for RV refrigerator applications.

  • 0.2 Amp & 1800 RPM Very low amperage and low speed! When combined with our fan controller only runs when needed. Thus, saves your battery for your RV living needs. Also, makes almost no noise due to low speed.
  • 25 CFM (cubic feet per minute)
    Will refresh all air in cooling unit compartment every minute!
  • 0.4 IWC (Inch of Water Column) Static Pressure
    A typical computer fan is 0.01 IWC, thus computer or muffin fans are not good for this application because just a slight back pressure will cause the fan to stop moving air.
  • Ball Bearing & Brushless Long life and low noise.
  • Lock Rotor/Auto Restart Protection Will not burn up due to motor becoming stuck like other fans.

Why do I want these special blowers only available through ARP Control?

  • These fans help defrost the fridge and keep a uniform temperature within the fridge by circulation/airator effect. Helps prevent lettuce from freezing on the bottom while milk spoils at top of the fridge.
  • 0.04 Amp, 2 CFM, Ball bearing, Brushless, Lock Rotor & Auto Restart Function.
  • No Replacing Batteries! The defrost/circulation blower fans are small, they will not take up room in your fridge.
  • Our fix fridge defrost/circulation blower fans will blow just the right amount of air & only when the fridge is producing refrigerant when using Fridge Defend fan controller. These fans solve the problem large computer fans create, that is taking up too much room in the fridge, blowing more air than needed, and causing efficiency issues that lead to excessive ware-&-tare on the cooling unit by cycling the cooling unit too much when fans run full-time.

Standard Service Charge $56.00

Due to the popularity of our control combined with our work load, we have introduced a standard service charge for product diagnostics. We build what we feel to be the highest quality RV type controller on the market, but not everything is perfect, thus we will take care of you. If a control is sent back to us, and no problems are found with the controller, clearly the issue is with other systems on your RV. Thus, we are providing value by charging for diagnostics checks of the Fridge Defend by ARP.


1) Ship your control to us only after using our Contact Us form to get shipping authorization and instructions.
Turn around time will be ASAP, but is dependent on our present work load.

2) Please include with your control the return shipping address and a note requesting service so our receiving department knows how to process your control.

3) Once we receive your controller and understand what your issues are, we will diagnose the controller and report back to the phone number provided. If your control is found to have defects in materials or workmanship there will be no charge. If no issues are found, or there is a non-warranty defect we will inform you of any charges before proceeding and/or returning the control to you.

Shipping Insurance for Cost of Merchandise $6.00

Our standard shipping fee of $13.50 does not cover the cost of parts sold.
