How to Replace Your RV Vent Fan
How to supercede your RV roof vent fan. Here is a detailed list of educational activity with pictures.
Have you e'er been been stuck inside where information technology'south hotter than the outside? It can be pretty horrible, just there is a solution. A vent fan!
Most RV'southward come with some sort of vent or exhaust fan in the ceiling. Our 2001 Lakota fifth wheel came with a 14′ x 14′ Fan-Tastic Vent roof fan. Turn that thing on high with a couple windows open on the cool side of the RV and instantly feel the cool air blowing through.
We also keep the vent fan running through the night on a depression setting, just to keep fresh cool air circulating throughout the night. They really do make a tremendous difference. But, what happens when information technology breaks and you cannot repair it? We had our 20 year erstwhile Fan-Tastic Vent Fan and it finally broke.
It could not lift the embrace anymore so we decided to go a new vent fan to supervene upon it. After doing plenty of enquiry, we decided to supersede it with a new Fan-Tastic RV roof vent with all the bells and whistles.
Measure the One-time RV Roof Vent Fan
Measure your erstwhile vent fan to make certain yous replace it with the correct size vent fan.
How to Supercede your RV Roof Vent Fan
Turn Off the Power
To start out, turn the power to the vent fan off at your RV's excursion breaker. If the power is left on, you could short circuit the line by accident. If your positive wire hits the aluminum frame accidently, y'all will blow a fuse. Turning off the ability will save you from using up a spare fuse.
Unscrew the Vent Fan Trim Ring
Remove the trim band to your RV roof vent fan by unscrewing the iv screws on the bottom side. It should so easily slide out.
To proceed things clean, I taped a plastic bag sealing the hole from underneath using masking tape.
Remove the Sealant from around the Vent Fan
Employ a thin metal putty knife gripped close to the cease and score the sealant around the RV vent fan's mounting edge. Exist careful not to cut too deep as to not cutting through the RV roof liner.
Utilise a plastic scraper or console removal tool to scrape the sealant off of the roof surface against the vent fan mounting edge. I highly recommend using plastic against the roof liner to reduce the possibility of damaging your RV'due south roof liner.
Remove Sealant from the Mounting Spiral Heads
The Fan-Tastic Vent Fan that our 5th wheel came with, had the cover's swivel mounted over the vent fan mounting surface and screws. I unscrewed the cover's hinge and using the help of my metal putty knife, removed the vent fan encompass.
Remove the RV Vent Fan Mounting Screws
Our 20 twelvemonth old Fan-Tastic vent fan'due south mounting screws were now all exposed. Employ a cordless drill to help unscrew each screw. In that location were a few screws that had been exposed to water and would spin free in the RV roof.
With the help of a putty knife and needle nose plyers, I was able to easily unscrew each compromised screw.
Use a large plastic panel removal tool or scraper to help costless the RV roof vent fan from the RV roof. At that place should be butyl tape holding the vent fan mounting surface to the RV roof. A footling pry here and there will help you pull the RV vent fan complimentary.
Clip the wires from the old vent fan and remove it from your work area.
Cleaning the RV Roof Surface
Apply your plastic scraper or panel removal tool to scrape every bit much of the old sealant off the RV roof equally possible. It is not very like shooting fish in a barrel only old sealant should be removed before installing the new vent fan. Be very conscientious not to impairment the RV roof liner.
Apply a clean rag soaked in rubbing alcohol to wipe three to 4 inches of the RV roof surface from the vent fan hole's edge. I used rubbing alcohol rather than acetone. Acetone is pretty powerful and could plow the RV roof liner gooey podtentially compromising it's sealing backdrop.
Set the Mounting Screw Holes for Larger Screws At present if doing so
Because our mounting holes in our fifth bike roof are 20 years old and bear witness evidence of weather exposure, I used larger approximate screws than the ones that come with the vent fan. So I did not crack the plastic mount of the RV vent fan, I drilled larger pilot holes so the screws could just slide through without brake. You do not desire your pilot holes besides large.
Make the Wire Connections of the New RV Roof Vent Fan
You can make the wire connections a few different ways. Apply Wire Crimpers and Butt connectors to make a permanent connection, use male and female connectors for a connection that can exist disconnected and reconnected, or use the twist, solder, tape method for a permanent connexion. I opted for the twist, solder, tape method.
Strip the positive and negative wires coming from the RV and the new RV roof vent fan. Twist the wire strands of each wire tightly. A tight twist in the multi strand wire is ever the all-time when making 12 volt wire connections. The twisted wires concord better when using connectors and in soldered joints. Criss cantankerous the stripped positive wires and twist each end around the other equally tightly as y'all tin.
Use a hot soldering atomic number 26 pushed against the twisted wire joint to heat the wire. Press some unspooled Rosin core solder into the hot twisted wire so the wire articulation soaks upwards the solder. Employ about 3 to 4 inches of electrical tape and wrap the solder joint tight. I used ii layers of tape. Repeat for the negative wires.
Butyl Tape the RV Vent Fan Mounting Surface
Prior to the butyl tape, make clean the RV roof vent fan mounting surface with a rag soaked in acetone. The acetone volition clean any body oils and manufacturing oils from the surface so the butyl tape sticks properly to the plastic mounting surface.
To assist make certain yous will have a water tight connection between the RV vent fan and your RV roof surface, put 3/four″ butyl record forth the mounting surface of the vent fan.
Press the butyl tape downwards and then it sticks well. Peel the backing off the butyl tape to expose it's sticky surface. Flip the RV vent fan over then the comprehend is facing upwardly. Make sure the wires are free and hang down through the hole into your RV equally you position the fan over the hole. Make sure the vent opens toward the rear of your RV and slide the vent fan into the hole in your RV roof.
Mounting the RV Vent Fan to Your RV Roof
Squeeze sealant/adhesive caulk into each mounting spiral hole and a bead around the mount edge where it meets the RV roof to fill any gaps. This is not the final sealing. I highly recommend "Moisture Seal". It works Amazing on RV roofs. This sealant is self leveling and stays liquid for a couple hours. Information technology was recommended to me by Mark at Sonrise RV in Escondido, CA. I called looking for RV Lap Sealant and they said they have something way improve, so I went with the "Moisture Seal".
Prepare the Wet Seal sealant tube by unscrewing the caulking tube tip, cut the tip off of the tube with a razer knife, screw the caulking tip back on, and load the caulking tube into a standard caulking gun.
There is no need to poke a hole through tip, the seal is open when the tip is cut off.
Instead of using the stock screws the new RV vent fan came with, I used a thicker judge screw to brand sure the threads got a practiced bite on the existing mounting holes. I first had to drill bigger pilot holes in the vent fan mount then the thicker screws would not crack the plastic vent fan mount. I did this step every bit soon as I removed the vent fan from the box.
Screw each spiral into the RV vent fan mountain until snug. You lot do not desire to strip the mounting holes.
Rain Hood Option
If using a rain hood, follow the mounting instructions. The mounting hardware that came with the rain hood we chose went on the second to first and terminal screws on both the driver's and passenger's side of the RV vent fan mount. Put a expert amount of Wet Seal sealant around the screw hole on the mounting bracket surface that volition come in contact with the vent fan mounting surface.
Make sure to make full the screw hole in the vent fan mount with sealant first. Place a screw through the spiral pigsty in the rain hood bracket with the sealant facing downwards. Place the pelting hood bracket sealant side down onto the RV vent fan mount so the spiral slides into the empty screw hole. Tighten the screw down so it is snug. Sealant will squeeze out from the edges of the rain hood bracket and screw head.
Squeeze plenty of sealant under the rain hood mounting subclass so the space is completely filled with sealant. This makes a water tight seal.
Mount the Pelting Hood
I really like the thought of having actress protection for the roof vent fan. Not but is this a how to replace your RV roof vent fan but a expert idea of what to include with your replacement for longevity of your investment.
Remove the protective plastic from the RV vent fan cover. Identify the rain hood over the RV vent fan so the posts on the mounting brackets go through the mounting holes in the rain hood foot's edge. Make certain the open side of the pelting hood faces to the rear of your RV. Information technology is easiest to do ane side outset and then adjusting the posts in the bracket so the other side will slide onto the posts of each remaining bracket.
Slide a supplied washer onto each mounting post. Then slide a safe clip through each hole in each mounting post.
Seal the RV Vent Fan to the RV Roof
Go around the edge of the RV vent fan mount with the Wet Seal sealant doing a zig zag motility to lay a 1 inch wide bead of sealant, 1/2 inch over the vent fan mount and 1/2 inch on the RV roof. Cover the spiral heads with sealant likewise.
You lot can utilize your putty knife to softly smooth the pinnacle of the sealant bead to make sure there are no air gaps. Exist conscientious no to push downward considering yous do not want to remove any sealant from the RV vent fan mount edge.
Install the Trim Ring on the Bottom Side of the RV Vent Fan
Slide the trim ring upward through the hole in the ceiling and into the vent fan. Be careful non to pinch the power wires. I used a small square of butyl tape at each corner to concord the trim band in place. Keep the butyl tape at least 1/viii inch from the edge so information technology does not squeeze out. Put a spiral that came with the vent fan onto your phillips screw driver or cordless drill phillips caput bit.
Push button the spiral into a screw hole in the trim ring, wiggle the screw back and forth until the screw tip finds the existing spiral hole and tighten the screw. Repeat for the remaining three screws. Make certain to tighten until snug, practise not over tighten. Yous exercise not want to crack the plastic trim ring.
Test out your new RV Roof Vent Fan.
That is how to replace your RV roof vent fan.
