One of the most common problems with atwood rv water heater is a pilot outage.
Atwood water heater no spark.
If it is not too old hen you can try cleaning the orifice and see how it goes.
Where is the reset button for the atwood water heater.
On my 10 gal atwood in my 2006 winnebago journey i found that there are two 1 4 inch studs sticking out of the back of the water heater with ground wires attached that had become so corroded that the ground wires were barely making contact.
Our water heater quit working so i took it upon myself to get it working again.

Ignition is not clicking.
For poor pilot flame you would need to replace the orifice.
It might be the thermal fuse that brings power to the board or the fuse on the board or the board itself.
This can happen if you have a weak gas control magnet or if the thermocouple needs to be replaced.
If you can pick one up this morning we can track this down quickly and find out where the problem is.

I am attaching a link to the atwood water heater manual for you.
This ignitor is for the newer model atwood water heaters only with only one wire.
That is the correct ignitor for older 2 wire water heaters.
Retmotor if you can access the back side of your water heater check to see if the ground wires are attached securely.
When i ve reached out to my contact at dometic in the past he has said that your atwood water heater like part at96121 either has a bad control board or bad electrode.
If you have an older model atwood water heater with 2 wires try searching for number 91606.
