A sail switch is a device that is used to turn on and off the flow of propane to a furnace in a recreational vehicle (RV). The sail switch is located near the furnace and is connected to the propane line. The sail switch is designed to shut off the flow of propane to the furnace if there is a fire in the furnace. This prevents the propane from feeding the fire and causing an explosion.

What is a sail switch?
A sail switch is a mechanical device that is used to indicate whether or not the wind is blowing. It is mounted on a mast or spar and is attached to a line. When the wind blows, the line is pulled and the switch is activated. The switch can then be used to activate a warning light or sound an alarm. Sail switches are used on both small and large boats.
How does a sail switch work?
A sail switch is a very simple device that is used to control the sails of a sailboat. The function of a sail switch is to change the angle of the sails to the wind. This is done by a rotating arm that is connected to the sails. When the arm is turned, the sails are turned to a different angle.
The sail switch is located at the base of the mast. It is a small black box with a handle that is used to turn the arm. The arm is connected to the sails by a series of lines. These lines are what actually control the sails.
The sail switch is operated by a series of pulleys. The handle is turned, which turns the arm, which in turn pulls on the lines, which changes the angle of the sails.
The sail switch is an essential part of a sailboat. It allows the sails to be controlled and adjusted to the wind. Without it, the sails would not be able to function properly.

Are there any drawbacks to having a sail switch on a RV furnace?
There are a few potential drawbacks to having a sail switch on a RV furnace. First, if the sail switch is not properly installed or calibrated, it can cause the furnace to cycle on and off more frequently than it should, which can shorten the lifespan of the furnace. Additionally, if the sail switch is triggered by a gust of wind, it can cause the furnace to turn off even if the RV is still in use, which can be an inconvenience. Finally, if the sail switch is not compatible with the RV's wiring, it can cause electrical problems.
How do you install a sail switch on a RV furnace?
When you're ready to install a sail switch on your RV furnace, the first thing you'll need to do is determine where the switch will be located. The ideal location for the switch is on the forward side of the boat, near the mast. This will ensure that the switch is within easy reach if you need to turn the furnace off in an emergency.
Once you've determined the location for the switch, the next step is to install the switch itself. The first thing you'll need to do is remove the old switch from the furnace. To do this, simply unscrew the switch from the furnace and pull it out.
Next, take the new switch and screw it into the same location. Be sure to screw it in tight so that it doesn't come loose.
Now that the new switch is in place, the final step is to wire it up. The first thing you'll need to do is connect the black wire from the switch to the black wire on the furnace. Next, connect the red wire from the switch to the red wire on the furnace. Finally, connect the green wire from the switch to the green wire on the furnace.
That's it! You're now ready to use your new sail switch.

How do you troubleshoot a sail switch on a RV furnace?
When troubleshooting a sail switch on a RV furnace, the first step is to check the switch itself. If the switch is damaged or not working properly, it will need to be replaced. If the switch is in good condition, the next step is to check the wiring. If the wiring is damaged or not properly connected, it will need to be repaired or replaced. Finally, if the sail switch is still not working properly, the furnace itself may need to be serviced or replaced.

What are some common problems with sail switches on RV furnaces?
Sail switch problems are common with RV furnaces. The sail switch is a safety device that turns the furnace off if the sail, or flame, goes out. If the sail switch malfunctions, it can cause the furnace to turn off unexpectedly or fail to turn on at all. Sail switches can become damaged or dirty, preventing them from functioning properly. Dust and dirt can also accumulate inside the furnace, interfering with the operation of the sail switch.
How do you replace a sail switch on a RV furnace?
Assuming you would like a step by step guide on how to replace a sail switch on a RV furnace:
Step 1: Locate the sail switch. The sail switch is a small, flat, rectangular switch located above the Burner. In most RVs, the sail switch is located on the left side of the furnace.
Step 2: Use a flat head screwdriver to remove the two screws that hold the sail switch in place.
Step 3: Gently pull the sail switch away from the furnace. You may need to wiggle it a bit to get it to release.
Step 4: Take a look at the back of the old sail switch. You will notice two small metal tabs. These tabs must be in the "up" position in order for the switch to work properly.
Step 5: Insert the new sail switch into the furnace. Make sure that the metal tabs are in the "up" position.
Step 6: Use the flat head screwdriver to screw the new sail switch into place.
Step 7: Test the furnace to make sure that the new switch is working properly.

Frequently Asked Questions
What is an RV furnace and how does it work?
An RV furnace is the rig’s main heat source. It uses both propane and electricity (12V). The propane creates hot air while electricity powers the electronics & circuits that turn on the heating system and which also runs the fans.
How does a propane heater work in an RV?
An RV thermostat controls the temperature in the RV by turning off or on the power to the furnace, depending on the temperature setting. The furnace is a fan that blows air through ducts thanks to electricity. When the thermostat reaches a heating temperature higher than that of the RV, the blower motor becomes automatically active. The heater also starts working as the propane gas burns to generate hot air. Then, the air blows through ducts, thanks to the electricity-run blower fan
What is a propane furnace and how does it work?
A propane furnace is a heat source that uses propane to generate heat. The fan circulates the heat around the room, and the circuit board controls the fan speed and furnace temperature.
