Going out on camping trips can be absolutely enjoyable. Enthusiasts want to spend far more time on their trips. It can be for weeks or even months at times. Considering this, they must plan appropriately so that they do not encounter any problems. As a result, they prefer to bring huge vehicles with instruments, such as motorhomes and RVs.

While there are numerous features that these vehicles provide them with, one of the best things that you can find is furnaces. Atwood is the best company for these products, and most manufacturers go with their products. However, if there is an issue with your device, it might not work.

This article will provide you with a list of troubleshooting steps for the Atwood 8535-IV-DCLP. It will help you get rid of the issues without much trouble.

Atwood 8535-IV-DCLP Troubleshooting

1. Check Wiring

Check Wiring

When trying to use Atwood Furnace, the most common issue people have with it is that the device is not working. However, you should note that this most likely means that the wiring on your device has been damaged.

This is why you should begin by ensuring that all of these are firmly connected. The wires in your car might become loose and fall off at any time while driving.

Considering this, tighten all of your wires to start using the furnace again. Aside from that, you should ensure that your equipment is receiving the exact quantity of electricity from its backend.

Usually, this should be a stable 12 volts. Use a voltmeter to validate the rating, and if the numbers fluctuate or are too low, unplug your gadget from the outlet. Using it on the same socket will most likely damage the system. Hence, it is preferable to use a different one and get this rectified.

2.Check Temperature

If you notice that the device is working fine but no heat or cool air is coming from the system, then you should keep in mind that the Atwood Furnace requires you to input a specific temperature. This will be followed by another test to confirm that you received the temperature you specified.

If you have not used the dial to change the temperature, then that might be why your furnace is not working. One way around this is to set the system to auto. It will automatically check the temperature to provide you with balanced heating or cooling.

3. Check the Gas Line

First, check the sealed valve on the furnace’s outside to verify if the gas is switched on . You can also validate gas availability by blazing something that burns it. Check to see if the gas is hitting the furnace adequately. Examine the valve to ensure that it is clear, open, and not affected in any way. Determine that the furnace receives the necessary quantity of gas for ignition. If you scent gas and notice a leakage, leave the area immediately and contact expert assistance.

4. Replace the Air Filter

Replace the Air Filter

Examine if the furnace’s air purifier, valves, and intakes have been recently updated, are tidy, and are not blocked in any way. The filter must be free of any obstacles and free of clogs. If you are unable to handle the ventilation difficulties on your own, get expert assistance to clean the exhaust vents for effective airflow.

5. Examine If The Battery Has Enough Power

A 10.5V power source is required for an electric RV furnace . A multimeter is an ideal tool for testing battery energy. You may also test this situation with a blower, which requires less electricity than the indicated voltage to operate. Connect one and test whether it works; if it does, the line voltage is insufficient for the furnace to burn. As a result, the battery must be replaced . If your battery is still under warranty, you can get it fixed by the supplier. If not, you may buy a new one in a store or order one online.

6. Check the Fuse

Check the Fuse

A fuse is placed between the power board of the electric RV furnace and its Dc generator. If black smoke is emitted from the fuse, it has burnt. A burnt fuse cuts off the power supply, resulting in ignition failure.

7. Examine Thermostat

A faulty thermostat might trick the furnace into thinking it has achieved a specific temperature when, in fact, it hasn’t. You can temporarily replace your RV’s thermostat with a low-cost model to see whether the problem remains. If it doesn’t, you’ll need to get a new thermostat . If it does, you should investigate more or consult a professional.

8. Clogged Drain

A condensate pan is included with the RV furnace to catch the extra fluid that spills from the furnace. If the drain becomes clogged, the pan can overflow with condensate, activating a sensor that instantly switches off the furnace to minimize leakage. To prevent this from happening, wipe the blocked drain with a wire or empty the pan regularly.

9. Check Power Switch

It may seem incredible, but furnace specialists frequently discover that the only “maintenance” a furnace needs is to be switched on. It makes no difference whether your RV heater is powered by gas or electricity; they both have a power button inside .

Check that it is switched on. You can also examine the breaker. If the furnace’s energy has been interrupted, re-energize it. If the incident persists, you should have your furnace inspected by a professional.

10. Thermocouple Failure

Thermocouple Failure

A thermocouple is also included in furnaces equipped with pilot lights. This gadget is for safety; it indicates whether or not the pilot light is on. When the pilot light fails, the thermocouple closes the valve, preventing gas or fuel from escaping.

When a thermocouple malfunctions, it may have difficulty distinguishing heat from the pilot light. As a result, it will progressively block the gas valve, resulting in the furnace not keeping lighted . You have two options: to engage an expert to conduct the repairs or just replace the defective item.

11. Automatic Mode Not Working

If you have already turned your Atwood Furnace to automatic and it is still not working, something may be amiss with its sensors. These are quite sensitive and will scratch if even a small amount of dust is stuck on them.

Then these will stop working, which is exactly why you should clean them off. Use a small pin for this, as the space above these sensors is quite small. However, make sure that you do not damage these accidentally.

12. Problems with the Blower Motor

Switch on the furnace and wait for it to heat up. Check to see whether warm air is coming out of the vent. Place your palm over a power register to do so, but be careful not to burn your body. If there is no hot air movement, the motor has run out of power.

To avoid the heating element overheating, the furnace is immediately shut off. It is also conceivable that the fan relay has been destroyed or that the motor belt has frayed. All of these motor issues may be resolved by employing a specialist.

13. Drain Lines Should Be Flushed

During the summer period, rising furnaces can waste several liters of water every day. The furnace will be halted if the drain pipes get clogged due to silt or mold development. If the drain hose seems to be unclean, remove it, fill it with a combination of diluted bleach, almost 25% bleach, and wash it after a few minutes.

If you’re having problems, it’s always a good idea to look for basic answers first. This will not only save you from a lot of discomfort, but it will also save you a huge amount of money. Furthermore, basic problems are the simplest to resolve, and you can typically handle them yourself even if you have no prior knowledge.

However, if the issues linger, they can become irritating and time-consuming. If you have any concerns about the system’s operation, you may easily replace it or talk with an expert.

  1. The issue I’m currently having is potentially a bearing in the blower. Heavy vibration coming from the interior intake vent. Solution?

    • Hey Marc. Most will tell you that you need new motor. I have mechanical abilities, so I dismantled and greased bearing, reassembled 40 minute job once motor is out.
