Atwood Furnace Reset Switch: How Do I Reset My RV Furnace?
There seems to be a hidden breaker switch on the top of the Atwood Furnace that will trip if something goes wrong. The problem is that RV makers do not tell you that it is there and it is not mentioned in the manuals. You need to follow the wires to get to this breaker switch
To learn more about this breaker switch and its location, just continue to read our article. It has the information you want to know about to help you get your furnace working again quickly. Take a few minutes to see how this information can help you.
Atwood Furnace Reset Switch Keeps Tripping
Pick a source. There seem to be quite a few reasons why your Atwood furnace trips the breaker or makes you use the reset button. One of those problems would be overheating. If there is not enough airflow, then the furnace will overheat causing the reset button to trip and stop the heat production.
Another cause for this problem would be low voltage. You would need to check the voltage output of your battery and if it is below 11.5 then that is your possible source of trouble. While you are doing this, check your blow motor cage and see if it is spinning freely. If it is rubbing it can cause the rest button to trip as well.
If all those parts are doing fine, check the circuit board. If there is a short or it is faulty, then that will cause problems for your furnace. The last possibility to be discussed here will be your exhaust.
Different insects and other animals tend to make nests in the exhaust especially if your RV has sat for a while. A good air nozzle and air pressure should take care of this issue.
How do I Reset my Atwood RV Furnace?
The trick to this task is first, to find the reset button. You will need to follow some wires from the furnace back to where the reset button is located. It is a rocker switch and the on side is smooth while the off side is rougher.
Click the switch to on, and then back to off again. Wait 30 seconds and then switch the rocker switch back on and your furnace should be reset. The trouble is that many RVs with an Atwood furnace do not have an outside access panel. You have to get to it from the inside.
Then you have to find the wires to trace back to the switch. It is a little inconvenient but once you get there the process should be easy to do.
Where is The Reset Button on an RV Furnace?
This button should be located on the top of your furnace. However, it is not that easy to find. There are red, black, and blue wires you need to trace back to find this reset button. However, the wires are not attached directly to the switch on the top of the furnace.
You will still have to feel around a little bit as the reset switch is about an inch or two on the far side of the wires. You may find that other models of RV furnaces may have easier-to-reach locations.
Check your owner’s manuals to see if they mention the location of the different reset buttons. Some manuals do not mention it so you may have to play the seek part of hide and seek to get to it.
Atwood Furnace Reset Switch Location
We took a look at one of Atwood’s furnace manuals and it does not mention a reset button. However, it does mention an on-off switch breaker which may be the same thing.
This switch breaker looks to be on the side of the furnace but it could also be placed on the top. It is hard to tell from the diagram but what is consistent with the comments we have come across, you do have to follow some wires to get to it.
The color of those wires is red and blue and this name change may be the reason for the confusion some RV owners have. People call it a reset button but manual writers use a different term like switch breaker.
It may not be the fault of the manual writers as the company could label the part that way as well.
Atwood Furnace Limit Switch/Airflow Problems
According to one mechanic, this switch rarely goes bad and that is a good thing. Its location is at the back of the furnace and you need to pull the whole furnace out to repair it.
To avoid problems with this switch, you need to make sure that none of the registers are blocked. All have to be in use for the limit switch to work properly. If your outlets are open and clear, the next step is to look for other causes.
This could be a mice family building their nest in the area or pet hair clogging the sail switch. If you have low propane pressure, that will cause overheating and trip the switch. Turn the furnace off to reset.
Some Final Words
Trying to find different parts can be difficult. RV makers or manual writers either do not mention these hidden parts or they relabel them with a name no one has ever heard of before.
That can make resolving the problem a little difficult. These are difficulties RV owners can do without. It would be better if the location of the reset switches were placed in an easy-to-reach spot.
