Automatic Rain Sensor

MaxxFan Plus Rain Sensor

The MaxxFan Plus has a rain sensor that detects when it starts to rain or snow. The sensor then automatically closes the roof vent and shuts the fan off, preventing the interior of your RV or trailer from getting wet. This allows you to leave your vent open and running without having to worry about the weather. Once the sensor has dried, you'll be able to open the vent and turn the fan back on. To deactivate the rain sensor, press the rain sensor button on the keypad.


Reversible, Variable-Speed Fan with Thermostat

MaxxFan Plus Fan Motor

The 12-volt, variable-speed fan has 2 modes of operation: manual and auto. When the fan is in manual mode, you can choose from 10 different speeds to increase or reduce the airflow as needed. Auto mode works in conjunction with the fan's thermostat.


To enter auto mode, press the auto mode button on either the remote control or keypad. Once the fan is in auto mode, the thermostat is activated with a set temperature of 78 degrees F. Pressing the arrow keys on either the remote or keypad changes the set temperature in 1 degree increments. When the thermostat is set, it senses the room temperature and automatically turns the fan on if it is above the set temperature. The fan shuts off when the set temperature has been reached. If the room temperature rises, the fan turns on again. This keeps your RV cool and comfortable and saves you from having to adjust the fan by hand. The auto mode also saves energy by running the fan no more than necessary, especially while you're away or asleep.


This fan is reversible, which means you are able to both exhaust stale air out of your RV and bring fresh air in from the outside. To enter ceiling fan mode, close the vent while the fan is still running. The fan then circulates the air inside your RV like a ceiling fan.


The fan has a fuse-protected, ball bearing motor that is sealed to keep out dust, dirt, and moisture.


Remote Control and Keypad

Remote for MaxxFan Plus

The remote control has a built-in LCD screen so that it's easy to see the current settings. The remote enables you to operate the vent and fan from afar, including opening or closing the dome and turning the fan on or off. With the remote, you can also control the fan speed, the direction of the airflow, and the set temperature for the thermostat.


The remote comes with a cradle, which mounts to the wall. When it's not in use, the remote can be stored in the cradle. Hardware and 2 AAA batteries are included. The low-battery indicator located on the top-center area of the screen lets you know when it's time to change the batteries.


Keypad for MaxxFan Plus

Like the remote control, the flush-mounted keypad on the vent allows you to operate the vent, the fan, and the thermostat. The rain sensor can only be activated or deactivated from the keypad.


Powered-Lift Dome with Twin Arms

MaxxFan Plus Dual Arms

The dome on this roof vent is constructed of durable high-density polyethylene, and it is translucent so that some natural light can shine through. When it's closed, the dome provides a seamless, low-profile appearance that blends into the roof of your RV.


This powered-lift dome opens and closes automatically, which means no hand cranking is needed. And unlike a dome that has only 1 arm, this dome is supported by 2 sturdy arms so that it will not flutter during high winds or while you are driving.


The dome has a sensor that will automatically shut off the lift motor when an obstruction is encountered or when the dome reaches the end of its travel. So, for example, if the dome cannot open all the way under your vent cover, a sensor will stop the dome once it has opened as far as it can.


MaxxFan Plus Manual Knob

And a manual hand knob is built into the underside of the vent to allow you to open and close the dome if your RV loses power.


Removable Bug Screen

MaxxFan Plus Bug Screen

This vent has a bug screen that helps keep insects and debris out of your RV. It is secured to the vent with 4 built-in retainer clips. These clips make it easy to remove the screen for cleaning or maintenance. Just rotate the clips, and the screen will pop out.


Installation

The MaxxFan Plus vent fits standard 14" x 14" openings in the roof of an RV, camper, or enclosed trailer. A white interior trim piece (or garnish), insulated electrical connectors, and hardware are included for installation. The vent also has a molded-in mounting flange that is lined with a rubber weather seal, which helps prevent leaks. Roof sealant (sold separately) is required for installation.


To install, connect the two wires on the vent to your RV's electrical system. The black wire is for power, and the white wire is for ground. Then insert the MaxxFan Plus into the opening in the roof and mount the flange to the roof. To finish, trim the garnish as needed to fit the thickness of your roof and install it.


MaxxFan Plus With FanMate Cover

For extra rain protection, install a MaxxAir FanMate vent cover (sold separately) using the molded mounting tabs located on the flange. The tabs are designed to align with the integrated brackets on the FanMate, allowing for a no-drill, tool-free installation. These tabs also have rubber inserts that prevent water from seeping in under the flange.

  • Maxxair 4951KS Roof Vent Cover that Attaches to Brackets on Base Assembly
    Actually the type of roof vent cover you need to attach to the vent cover brackets of your Maxxair 4951KS like part # MA00-04500K is the part # MA00-955003 which uses those brackets with the included cotter pins of the cover.

  • Troubleshooting MaxxAir Vent Powered Lid that Won't Open
    I've attached the owners manual for your 4900K model which is similar to the # MA00-04500K model. It sounds like your operator mechanism is bad according to my tech contact at MaxxAir. For your 4900K model you will want the Replacement Operator Mechanism for MaxxAir MaxxFan Plus or MaxxFan Deluxe Roof Vents # MA10-20281K-1AF. If you can't even manually lift the lid, this mechanism is definitely the issue.

  • Can MaxxAire II RV Roof Vent Cover Attach to Rvlovent RV Roof Vent

  • RV Roof Vent Solution that Also Has Wall Control
    Hey Devon, does your RV roof vent wall control unit look like the # MA59FR? If so you have a MaxxFan Plus RV roof vent that was designed for wall control and for a replacement unit you would want the part # MA00-04500K to use a setup that would use same wall control and wall control wiring. Otherwise you'd have to go with this same unit and also swap out the wall controller.

  • Replacement Fan Recommendation for the MaxxAir 4700K
    Since the discontinued MaxxAir 4700k model fits a standard 14 x 14 RV vent opening, I recommend the MaxxFan Plus Roof Vent w/ 12V Fan - 10 Speed # MA00-04500K. The MaxxFan Plus comes with a thermostat and a remote for easy temperature customization. Also, with the powered lift feature, you do not have to go through the pain of having to manually lift the vent by hand. It also closes automatically with the rain/snow sensor to keep you dry. I went ahead and attached a video that walks you...

  • Can I Power A MaxxAir Fan And Some LEDs With This Converter?
    This converter you're looking at # 34266168 is rated for 600 watts and 45 amps. If you were to run something like this # MA00-04500K and a dozen or more LED lights, you won't go over the converters power rating. This one has a cooling fan on it so even if it does get hot, the fan will do a great job at keeping things cool.

  • Replacement Lid & Operator Mechanism For MaxxFan Plus 4500K Roof Vent
    Let's go ahead and start with the lift mechanism, which is also called the operator mechanism for your MaxxFan Plus Roof Vent # MA00-04500K, which is faulty and why your fan won't stay open. For that we do offer the replacement: - Replacement Operator Mechanism # MA10-20281K-1AF In regards to the replacement lid in Smoke for your MaxxFan Plus vent, we do have that part, which is the following: - Replacement Lid for MaxxFan and MaxxFan Plus Roof Vents - Smoke # MA10A40009K

  • How Tall is the MaxxAir MaxxFan Deluxe # MA00-05301K

  • MaxxFan 2016 Keystone Montana Model 3710FL Won't Stop Running
    If your MaxxFan with the rain sensor, like part # MA00-04500K, starts operating automatically and the controller or the controls on the unit aren't working then that sounds like a bad circuit board or that the built-in safety feature for too much (or not enough) voltage was activated and the circuit board locked up. Since you already removed power from the vent try connecting it back to power. If it works properly then it was just locked up and needed to be disconnected from power to unlock...

  • Troubleshooting MaxxAir Vent Fan that Won't Turn On and Rain Sensor Light On
    I spoke with my contact at MaxxAir regarding your vent like the MaxxFan # MA00-04500K. He said what you are experiencing might be caused by a short in the rain sensor. Since that light is coming off and on, this is likely the issue and what is also causing the fan not to turn on. He recommended taking a rag with some rubbing alcohol and simply cleaning out this sensor. Hopefully once it is cleaned out, everything should start working again as normal. If you are still having issues, please...

  • Can the Rain Sensor on a MaxxAir Vent be Overridden
    MaxxAir vents that have an integrated rain sensor, like the MaxxFan Plus Roof Vent # MA00-04500K, do not allow you to override the sensor. If you were to override it you would be allowing rain to hit the motor which could definitely damage it. The sensor will close the lid and shut off the fan when it is wet, but when it dries up the vent will open up and turn the fan back on.

  • MaxxFan Plus Roof Vent Cycles a Few Times After Vent is Closed
    If you have the MaxxFan Plus Roof Vent # MA00-04000K installed then it would make sense that the fan would continue to operate with the vent closed as this acts as a ceiling fan when the vent is closed. Should you have a different MaxxFan just let me know what the model is and I can look into it further.

  • Troubleshooting MaxxAir Fan Buttons Not Working
    Since the remote works we know the board isn't totally shot. I'm guessing it is the wiring for the control switch. All you can really do is check that wiring to make sure it is secure and no corrosion is present at both ends. If you decide to go ahead and replace the fan we have the # MA00-04500K or # MA00-07500K which both come with a remote and will fit your existing opening.

  • MaxxAir MaxxFan 4500K Doesn't Want To Spin In Exhaust Direction
    It sounds like a problem with the Circuit Board # MA10A21275K on your MaxxAir Roof Vent # MA00-04500K. I recommend using a Multimeter # PT89ZR to test voltage coming out of the circuit board going to the fan to verify the issue is not also with the Motor # MA10-20968. If you do not have a multimeter you could also switch the terminals around to see if the fan doesn't want to spin on the intake direction which would verify the issue is with the circuit board.

  • Are Any RV Roof Vent Covers Over 11" Tall
    RV roof vent covers throughout the industry max out at 10-1/4" tall so you'd be limited to this height. Manufacturers know that this won't allow for the vent lid to fully open but have stated that as long as the lid is opened at least 50% there will be no issues with performance. I recommend matching the cover to the brand of vent you have to make installation easier. For MaxxAir I recommend the following: Black # MA86JR Smoke # MA26JR White # MA76JR For Dometic/Fan-Tastic Vent I recommend...

  • Are There Any Troubleshooting Steps For A MaxxAir MaxxFan Rain Sensor
    There really isn't any troubleshooting that you can do with a MaxxAir Rain Sensor besides just making sure the vent has a full 12v of power and that the rain sensor cable isn't damaged and is fully plugged in. If it isn't working properly all you can really do is simply replace it with # MA34FR.

  • Replacement Lid Needed for Maxxair 4951 Vent on 2018 Grand Design
    Thank you for all of the info! Based off of that, and another question a customer sent in of the Maxxair 4951 on their 2018 Grand Design Reflection, the roof vent that you have is the same as the MaxxFan Plus Roof Vent w/ 12V Fan # MA00-04500K so your replacement lid is either part # MA10A40002K in white or part # MA10A40009K in smoke. We don't have the clear lid but either of these will fit great with your MaxxAir.

  • Is the MaxxAir MaxxFan Mini Roof Vent MA00-04401M Reversible
    The MaxxAir MaxxFan Mini Roof Vent part # MA00-04401M is not reversible, it only moves air one way which is out. If you're looking for a reversible fan that moves air both in and out, I recommend the MaxxFan Plus Roof Vent part # MA00-04500K which is the next step up from the above fan as far as features go. This one features a ten speed fan motor, powered lift, thermostat, rain sensor, remote, and more.
