Slide-out problem
One of the most common issues related to Keystone RV furnaces is a slide-out problem. This occurs when your furnace doesn’t respond properly when you move it out or in, either not turning on or off as expected. If you find that this is happening to your furnace, it’s important to make sure all the wiring connections are secure and that the slide-out switch is working properly. If everything appears to be in order, it may be necessary to replace the furnace’s control board or thermostat. [1]
Bad Sewage Smell
A bad sewage smell coming from your furnace can be alarming, and there are a few potential causes. The most common cause is simply a dirty filter which needs to be changed regularly. Another potential cause is a clogged sewer line or vent pipe. You can try running water down the drain to see if this helps clear the blockage. If the smell persists, it’s best to contact a qualified RV technician for further assistance. [1]
Chassis-related problem
Chassis-related problems are the most common Keystone RV furnace issues. These can manifest in different ways, from overheating due to a blocked air filter, to lack of fuel delivery due to a weak spark plug or even an incorrect wiring connection.
One possible problem that could occur is motor damage, as this part of the RV furnace is responsible for powering the internal heating element. If the motor has difficulty starting, or runs loudly and inefficiently, then you may need to have it serviced or replaced. [1]
Loose Motor Screw
Loose motor screws are a common problem that can cause Keystone RV furnace to malfunction. To fix this, you will need to locate the loose screws on the motor and tighten them with a screwdriver. If the screws seem too tight or won’t stay in place, try using some thread-locking compound to ensure they remain secure. Additionally, if the screws have rusted, replace them with new ones. [1]
Loose Driver Side Door
It’s common for the driver side door to become loose on your Keystone RV. This is often caused by a lack of maintenance, or simply due to wear and tear over time. If your door develops this issue, it may cause difficulty opening and closing the door correctly. You can usually fix this problem yourself; here’s what you need to do:
- Inspect the door hinges and make sure they are secure and not rusty.
- Make sure the screws connecting the hinge to the RV frame are properly tightened.
- If necessary, replace any missing or damaged screws with new ones; these can generally be found at your local hardware store or online.
- If the hinge is not properly aligned, you may need to take the door off and adjust it before reinstalling it. [2]
Unsuitable Exhaust Design
One of the most common and difficult Keystone RV furnace problems to diagnose is a poor exhaust design. If your RV has an old or inefficient exhaust system, it can cause serious damage to the appliance and lead to potentially dangerous situations. Poorly designed RV furnaces are often hard to detect until there’s a catastrophic failure. [2]
Battery Low Quality
When it comes to common Keystone RV furnace problems, battery low quality is one of the most common issues. This can cause your furnace to fail to ignite or even shut down after running for some time. To prevent battery low quality from causing any problems with your furnace, check the voltage level of your batteries regularly and ensure that they are always well-charged. If your battery voltage is low, charge it first and then check the furnace again.
You can also prevent further issues by replacing the batteries with higher quality ones that are designed for RV use. Make sure to always match the power output and amps of the new replacement batteries with those of your existing ones. As an added measure, it’s a good idea to invest in a deep-cycle battery charger so that your batteries can be recharged whenever necessary. [2]
Loud Noises
If your furnace is making loud noises, it’s most likely due to a lack of lubrication in the blower motor or fan. This can be easily fixed by lubricating the parts with oil and ensuring that all screws, bolts, and fasteners are securely tightened. If the noise persists after this, you should contact a professional repair service.
Additionally, if your furnace is making loud noises, it may be due to a clogged air filter or intake vent. Replacing the filter should resolve the problem; however, if it doesn’t, you’ll likely need to get professional help as this could indicate a more serious problem with your furnace.
Finally, make sure you clean out the dust and debris from the furnace periodically, as a build-up can lead to loud noises. [2]
Fewer cup holders
When it comes to common Keystone RV furnace problems, there are a few things that can cause issues with your vehicle. One of the most frequent ones is when the pilot light does not ignite or stay lit. This issue arises when air is leaking into the chamber where gas is being burned. The air prevents the flame from igniting or sustaining a flame. This is caused by the valves not being properly sealed and can be fixed with an adjustment of the valves, replacing parts if needed. [2]
Seat belt problems
One of the most common problems that Keystone RV owners may experience is seat belt issues. The seat belts in Keystones are very important for both driver and passenger safety, and it’s important to make sure they’re working properly. Common problems include:
- Seat belts not locking into place when fastened or released.
- Seat belt retractors not working correctly.
- Latch plate not engaging properly with the buckle, preventing the seat belt from locking into place. [2]
Sway bar bushing problem
One of the common Keystone RV furnace problems is a sway bar bushing problem. This occurs when the metal bushing that attaches the sway bar to the frame has worn down or become damaged. This can cause your furnace to shake and make loud, uncomfortable noises. It is important to check for this issue regularly – especially after traveling long distances in your RV.
If you suspect a sway bar bushing problem, it is important to have it checked and fixed as soon as possible. A mechanic should be able to replace the worn or damaged bushing relatively easily – though this can be a time-consuming task. It’s also worth taking some preventative measures such as checking for any visible wear and tear before you hit the road. [1]
AC Is Blowing Cold Air When Needing Heat
If you turn your RV’s AC on and cold air is coming out instead of warm, it could be a sign that the furnace isn’t working correctly. This problem can usually be fixed by checking the thermostat and ensuring that it is set to heat mode. If this does not work, then you may need to check the wiring that is connected to your thermostat. It could be that the wires are not connected properly and need to be adjusted. You may also want to check if there is a blown fuse or tripped breaker, as this can cause power issues with the furnace.
Alternatively, it could simply be an issue with the fan motor itself. If this is the case, you may need to replace the fan motor in order to get your furnace back up and running. If none of these steps work, it may be time to call a professional for assistance. With their expertise, they will be able to identify and fix the problem quickly and efficiently. [3]
Keyless Entry Doesn’t Work
One of the most common issues RV owners face is when their keyless entry doesn’t work. If your keypad isn’t responding, try these troubleshooting tips:
- Check to make sure your batteries are properly installed and that they have enough charge.
- If you recently changed the code, make sure it was entered correctly.
- Try pushing and releasing the reset button on the face of the keypad, then enter your code.
- If you’re still having difficulty, contact a qualified technician to check for any wiring problems or other malfunctions. [3]
Can’t Set My Rear Cameras On To Watch Full Time
One of the most common issues people have with their Keystone RV furnaces is not being able to set the rear cameras on to watch full time. The good news is that this issue can be easily solved by checking all of your wiring and connections. Some typical problems include a loose connection or faulty wiring that needs replacing. Additionally, make sure to check the fuse box to ensure it is properly connected.
If the wiring and connections all look good, then you may need to check that your furnace is getting enough power. It’s possible that something else in your RV is taking up too much of its power supply, leaving your furnace without the proper wattage to turn on the rear cameras. [3]
Slide Room Is Going In And Out Crooked
One common issue that owners of Keystone RVs may experience is the slide room going in and out crookedly. This can be caused by a number of different things, such as incorrect alignment of the slides, loose bolts on the frame, or worn-out bearings on the slide room itself. If you suspect this is happening to your RV, it’s best to contact a certified Keystone technician right away. The technician will be able to inspect the slide room and diagnose any underlying issues. [3]
No Water Pressure
If you find that there is no water pressure in your RV, it is likely due to a clogged line or faulty RV furnace. If the water lines are clogged, you can use a plumbing snake to clean them out. You may also need to replace the entire system if parts have corroded or become damaged over time. [3]
Microwave Vents Rattling
A problem that many Keystone RV owners have noticed is that the vent in their microwave can start to rattle. This rattling sound can be quite loud and annoying, but fortunately it can often be fixed without too much effort. The first thing you should do is check to make sure all the screws are tight – if not, tighten them up. If that doesn’t help, then you can try adding some foam insulation around the vent to reduce the vibration. Finally, if these methods don’t work, it may be necessary to replace the vent with a new one. [1]
Washer Making Noises When Not In Use
Sometimes, an RV furnace can make noises even if it’s not in use. This can be caused by a few things, such as the blower motor or fan belt wearing out over time. It may also be due to worn bearings in the motor itself. To determine what is causing the noise, you will need to inspect your furnace and check whether any of the components are loose or damaged. If the noise persists, it’s best to contact a professional for a proper diagnosis.
Another common cause for noises is a build-up of dust and debris inside the RV furnace. This can lead to parts becoming clogged and not working properly. To prevent this from happening, it’s important to regularly clean and maintain your furnace. This means checking the filters, lubricating any moving parts, and ensuring that everything is in good working order. [2]
Propane Pressure On Outside Grill
For Keystone RV owners with an outdoor grill, one of the most common furnace issues is propane pressure. This can be due to a few different things and should be checked out by a professional if it persists. If you notice your outdoor grill isn’t getting enough fuel pressure, check the following:
- Make sure there are no blockages in the hose leading from the propane tank to the grill.
- Check the regulator on your tank for any signs of wear and tear, which can cause pressure issues.
- Examine the hoses for any kinks or tears that may be restricting flow.
- Ensure all fittings are securely tightened. [1]
