Maxxair fans have a self-resetting fuse incorporated in the ceiling assembly, on the circuit board. To reset the fan, disconnect its 12V power supply and plug it back in after a few seconds. Turn the fan on and set all the controls up to complete the process.
Maxxair is currently leading the way in the RV vent fans industry. The Maxxfans are popular for their slick design, easy-to-navigate controls, reliability, and lifelong optimal span. Like any other machine, from time to time they may encounter technical problems and need to be reset.
In this article, we discuss the many different models of Maxxair and how to reset them.

How to reset a Maxxair Fan
The Maxxair fans do not include a reset button, but you can still reset the fan:
Remove and Reapply The Power
To reset a Maxxfan, disconnect it from the battery or shore power and then reconnect it after a few seconds. This will activate the self-resetting fuse located in the ceiling assembly, on the circuit board.
All the settings will have been cleared, and you will need to reselect them, following these steps:
1. Turn On
Once you reconnect the fan, the next step is to turn it on.
- If you are using a remote control model, you can simply use the remote to turn the fan off.
- If your fan requires manual controls, locate the keypad on the insect screen and press the “FAN ON” button.
The Maxxfan Deluxe has many sub-categories. Its versions 5301K and 6401K have a separate button to turn the fan on or off. In contrast, a large range of other models like 5100K, 5101K, 6200L, 7500K, 8501K, the intake/exhaust, exhaust only models, etc., come with only one power button that does the task.
Make sure to switch the fan off before disconnecting its power supply from the main outlet to reset the device.
2. Mode Selection
In the ten speed models there are two modes that the fan runs on: auto mode and manual mode.
The primary difference between the auto and the manual mode is that the former enables the thermostat to turn the fan on or off as per the thermostat settings.
Although the fan automatically switches speed in the manual mode as well, it does not switch off regardless of the temperature. When reaching the maximum or the minimum speed limit, the fan registers two quick beeps.
The control keypad includes a “HOLD TO SET” button.
- Upon pressing the key once for less than 3 seconds, the fan enters the auto mode.
- The LED illuminates solid green, and the fan gives off three quick beep sounds indicating the auto mode selection.
- To exit the auto mode, press the power button (on/off key) once.
3. Temperature Settings
The desired temperature can be set when the fan is running on auto mode. After turning the auto mode on, the temperature is by default set to 77°F/25°C.
If you wish to change the set temperature,
- Press the “HOLD TO SET” key for more than 3 seconds till you hear one long beep. This resets the thermostat to the initial factory set point.
- Now use the “+ or -” button to set the desired temperature.
- This setting is confirmed by a single beep sound.
The thermostat gauges the cabin/room temperature and automatically alters the fan speed to maintain the value at the set point.
4. Fan Speed
In the basic models, like 5301K and 6401K, the fan speed ranges between 1 to 4. For these models, the user cannot select a particular speed. The fan continuously cycles from 1 to 4 and back to low speed.
However, the ten-speed models that come with a built-in thermostat let you set the fan speed on manual mode.
- There are “+” and “-” buttons that help adjust the speed of the fan.
5. Vent Lid Position
You can choose to keep the vent lid opened or closed with the help of the “VENT LID” button. This key is only active in manual mode. When the fan motor is on, you can close the vent lid to make the fan switch to the ceiling mode automatically.
In the basic models (5301K and 6401K) that do not come with a button, you can use the knob to open or close the vent lid.
- Rotate the knob clockwise to close the lid and anticlockwise to open it.
- To lock the position of the vent, push the “IN” button.
Vent covers (FANMATE) are optional and are available either directly through Airxcel or via Amazon.
6. Fan Direction
Maxxair allows a user to set the fan’s direction with the help of an “IN/OUT” button.
- The fan stops for two seconds when the button is pressed once and then positions itself to operate in the opposite direction.
In the auto mode, the fan is set to the exhaust mode until you change it by pressing the key.
The “IN/OUT” key is not present in Maxxair’s exhaust-only models.
Why your Maxxair Fan is Beeping
Maxxair fans beep when the fan is connected to a power supply. Beeping also occurs every time settings are changed on a Maxxfan, and their duration and frequency are specific for each function.
The following points summarize beep sounds and their relation to each control in the Maxxair fans:
- All Maxxair fans beep when they are connected to a power supply
- Two quick beeps when the fan hits the maximum or the minimum speed limit in manual mode
- Three quick beeps when the fan enters auto mode (LED also illuminates solid green)
- One long beep when the thermostat resets
- Single beep sound when the temperature is set
Thus, beeping in Maxxair fans is normal. In fact, if the fan does not beep in the above-mentioned situations, especially when connected to the 12V power source, you should check for a possible problem.
However, if the green light starts blinking/flashing and beeping or if it is a solid green and is not responding there may be either a power/battery issue, or a circuit board issue.
- Ensure the power supplied to the Maxxair fan is correct
- If necessary, replace the circuit board.
How to Use a Maxxair Fan
To use a Maxxair fan, install the fan in an appropriately sized space. Connect it to a 12V power supply and turn it on. Set the mode, temperature, fan speed, fan direction, intake/exhaust (depending on the model) as per your preference.
The controls of Maxxair fans are generally easy-to-navigate. Both exhaust and intake/exhaust models are available (refer to the table in the post).
Here are some steps explaining the installation and usage of Maxxair fans:
- Apply sealant within the area you want the fan in. Now fix the four metal poundings on the roof and seal them in place. Slot the fan in place.
- Connect it to a 12V power supply. Remember that all Maxxair fans need a steady 12V source, or the fan won’t work. A beep sound indicates proper connection.
- Turn the fan on using the power button.
- Select the auto mode or leave the fan as is if you want to run it in manual mode.
- Set the thermostat and fan speed as instructed in the article.
- Choose if you want to keep the vent opened or closed.
- Select either the ceiling mode or the exhaust mode (this is only for intake/exhaust models)
- Whenever the fan starts malfunctioning, try resetting it. To do so, disconnect the power supply and reconnect it after a while. Now set all the controls, and you are good to go.
