How to Reset Furrion Thermostat

Resetting your Furrion thermostat can solve common issues like unresponsiveness, incorrect temperature readings, or system errors. This guide walks you through simple reset methods, from soft resets to factory restores, ensuring your RV or cabin climate control works smoothly.

If you’ve ever been stuck in an RV that’s either freezing cold or sweltering hot—despite cranking up the heat or AC—you know how frustrating a malfunctioning thermostat can be. The Furrion thermostat is a popular choice among RV owners and tiny home dwellers for its sleek design, digital display, and compatibility with Furrion’s climate control systems. But like any electronic device, it can occasionally act up. Maybe it’s not responding to touch, showing the wrong temperature, or simply refusing to turn on. Before you panic or call a technician, there’s a good chance you can fix it yourself with a simple reset.

Resetting your Furrion thermostat isn’t just about pressing a button—it’s about understanding what kind of reset your situation needs. There are different levels of resets, from a basic soft reset that refreshes the system to a full factory reset that wipes all custom settings. Knowing when and how to use each method can save you time, money, and a lot of frustration. In this guide, we’ll walk you through every step, explain why each reset works, and share insider tips to keep your Furrion thermostat running like new.

Why Reset Your Furrion Thermostat?

Thermostats are the brain of your heating and cooling system. When they stop working correctly, your entire climate control setup suffers. A Furrion thermostat might need a reset for several reasons. Sometimes, it’s just a temporary software hiccup—like when your phone freezes and needs a restart. Other times, it could be due to power fluctuations, outdated firmware, or even dust buildup inside the unit.

One of the most common issues is unresponsiveness. You tap the screen, but nothing happens. Or maybe the display is blank, even though the unit seems to have power. Another frequent complaint is inaccurate temperature readings. Your RV feels chilly, but the thermostat says it’s 75°F. That’s not just annoying—it can lead to wasted energy or discomfort.

Power-related problems are also common. RVs run on 12V DC power, and if your battery is low or your converter isn’t working properly, the thermostat might not get enough juice to operate. This can make it seem broken when it’s really just underpowered. Similarly, if you’ve recently disconnected your RV from shore power or switched batteries, a reset can help the thermostat re-sync with the system.

Firmware glitches are another culprit. Like any smart device, Furrion thermostats run on software. If an update was interrupted or the system encountered an error, it might freeze or behave oddly. A reset can clear these temporary errors and restore normal function.

Finally, environmental factors play a role. If your thermostat is mounted near a window, vent, or heat source, it might read temperatures incorrectly. While this doesn’t always require a reset, it’s good to check placement before assuming the unit is faulty.

Types of Furrion Thermostat Resets

Not all resets are created equal. Understanding the difference between a soft reset and a hard reset is key to solving your problem without causing more issues.

Soft Reset (Power Cycle)

A soft reset is the simplest and safest option. It’s like restarting your computer—it clears temporary memory and refreshes the system without affecting your settings. This is ideal for minor glitches like a frozen screen, delayed response, or incorrect temperature display.

To perform a soft reset:
1. Turn off the thermostat using the power button or by switching off the breaker that controls it.
2. Wait at least 30 seconds. This gives the internal capacitors time to discharge.
3. Turn the power back on and wait for the thermostat to reboot.

You should see the Furrion logo appear, followed by the home screen. If the issue was temporary, this often fixes it. For example, if your thermostat was stuck on “Heat On” but your furnace wasn’t running, a soft reset might clear the false signal.

Hard Reset (Factory Reset)

A hard reset is more drastic. It restores the thermostat to its original factory settings, wiping out all custom preferences like temperature schedules, fan settings, and mode configurations. Use this only if a soft reset doesn’t work or if the unit is completely unresponsive.

To perform a hard reset:
1. Make sure the thermostat has power.
2. Press and hold the “Mode” and “Fan” buttons simultaneously for 10–15 seconds.
3. The screen will go blank, then display the setup menu.
4. Follow the on-screen prompts to reconfigure your settings.

Note: The exact button combination may vary slightly depending on your Furrion model. Check your user manual for specifics. After a hard reset, you’ll need to set your preferred temperature ranges, schedule, and system type (heat pump, gas furnace, etc.).

When to Use Each Reset

Use a soft reset for:
– Temporary freezes or lag
– Incorrect temperature readings that correct themselves after a reboot
– Minor display issues

Use a hard reset for:
– Complete unresponsiveness
– Error codes that won’t clear
– Persistent malfunctions after a soft reset

Always try the soft reset first. It’s faster, safer, and doesn’t require reconfiguration.

Step-by-Step Guide to Resetting Your Furrion Thermostat

Now that you know the types of resets, let’s walk through the actual process. These steps apply to most Furrion thermostat models, including the FURRION FAC12V1A and similar units.

Step 1: Confirm Power Supply

Before resetting, make sure your thermostat has adequate power. Check your RV’s battery voltage with a multimeter—it should read at least 12.4V when fully charged. If it’s below 12V, charge the battery or connect to shore power. Also, inspect the breaker panel to ensure the thermostat circuit hasn’t tripped.

Step 2: Perform a Soft Reset

1. Locate the power source. This could be a dedicated breaker, a switch on the thermostat, or the main power panel.
2. Turn off the power to the thermostat.
3. Wait 30–60 seconds.
4. Turn the power back on.
5. Wait for the unit to boot up (usually 30–60 seconds).

If the thermostat responds normally, you’re done! If not, proceed to a hard reset.

Step 3: Perform a Hard Reset

1. Ensure the thermostat is powered on.
2. Press and hold the “Mode” and “Fan” buttons at the same time.
3. Hold for 10–15 seconds until the screen goes blank.
4. Release the buttons when the setup screen appears.
5. Follow the prompts to reconfigure your system.

Tip: Take a photo of your current settings before resetting so you can easily restore them.

Step 4: Test the System

After resetting, test both heating and cooling modes. Set the thermostat to heat and verify that the furnace kicks on. Then switch to cool and ensure the air conditioner responds. Check that the fan operates in auto and on modes.

Step 5: Monitor for Recurring Issues

If the problem returns within a few days, it may indicate a deeper issue—like a faulty sensor, wiring problem, or failing control board. In that case, contact Furrion support.

Troubleshooting Common Reset Issues

Even with the right steps, you might run into hiccups. Here’s how to handle them.

Thermostat Won’t Turn Back On After Reset

If the screen stays blank after a reset, check the power source again. Use a multimeter to test voltage at the thermostat terminals. If there’s no power, inspect the wiring, breaker, and fuse. A blown fuse is a common cause—replace it with one of the same rating.

Buttons Don’t Respond During Hard Reset

Some models require precise timing. Try pressing the buttons immediately after powering on. If that doesn’t work, consult your manual—some units use different button combinations (e.g., “Up” + “Down”).

Settings Keep Resetting on Their Own

This suggests a power instability issue. Check your RV’s electrical system for loose connections, corroded terminals, or a failing converter. A voltage drop below 11V can cause the thermostat to reboot unexpectedly.

Error Codes Appear After Reset

Furrion thermostats may display error codes like “E1” (sensor fault) or “E2” (communication error). Refer to your manual for code meanings. Often, these require professional diagnosis.

Preventing Future Thermostat Problems

A reset fixes the symptom, but prevention keeps the problem from returning. Here’s how to maintain your Furrion thermostat.

Keep It Clean

Dust and debris can interfere with sensors and buttons. Use a soft, dry cloth to wipe the screen and vents monthly. Avoid harsh cleaners—water and mild soap are sufficient.

Ensure Stable Power

Invest in a quality battery maintainer or solar charger to keep your RV’s battery topped off. Consider a voltage monitor to alert you to drops.

Update Firmware When Available

Check Furrion’s website periodically for firmware updates. Some models allow updates via USB or Wi-Fi. Updated software can fix bugs and improve performance.

Check Mounting and Placement

Mount the thermostat away from direct sunlight, drafts, or heat sources. Ideal placement is on an interior wall, about 5 feet above the floor.

Inspect Wiring Annually

Loose or corroded wires can cause intermittent issues. Turn off power and check all connections at the thermostat and control board.

When to Call a Professional

Most reset issues can be handled at home. But if you’ve tried both soft and hard resets and the thermostat still doesn’t work, it’s time to call in help. Signs you need a technician include:
– No power despite confirmed voltage
– Burned smell or visible damage
– Persistent error codes
– Furnace or AC not responding even with a working thermostat
