I’m very sorry for your loss. There is alot to learn about your Bounder. I’m sure you feel an emotional attachment since it was your Dad’s.
I’m guessing you have Atwood furnaces.
The furnace igniter is inside each furnace. It’s not easily accessible
There are probably 3 access doors on the exterior of your coach - 1 has a spring loaded rotating lock - that is the water heater.
The other 2 have 4 screws each. They’re your furnaces.
I’m guessing you have a 30 amp system. In shed mode, the system diverts power between the front and rear rooftop AC units
The thermostat triggers a delay relay in each furnace. Those go bad and can be replaced.
Each furnace has a control board Pull the covers off and follow the wires. The board is probably to the left. They go bad too.
Each furnace has a 12 volt blower motor. They go bad. Reach in and rotate the squirrel cage fan on the motor. If it’s seized or hard to spin it’s probably bad
Once you open the furnace cover, look for the make and model of your furnace and then start Googling. You will find helpful videos
There should be a 5 volt fuse for the furnaces - the fuse panel may be in the cabinet with the ECC shown in your photo.
On my coach one furnace had a bad motor and the other furnace had a bad delay relay. Neither worked but the problem wasn’t the thermostat, ECC or igniter.
If you have a voltmeter turn the thermostat to heat mode, set it to 80 degrees and check voltage on both sides of the relay. If the relay is bad, no voltage is getting to the motor and the igniter isn’t being triggered.
Mud daubers and other bugs nest inside the furnace. Debris gets inside.
You may need to clean them out. If the air flow is diminished by the debris, the furnace will shut down.
If you’re handy, you might want to pull the motors out. There is a device inside the motor housing called a sail switch- it’s triggered by the force of the furnace fan air. Sail switches go bad and get debris on their blades that keep them from working.
If your patient, you can figure this out.
Good luck!

There are two lights at bottom of thermostat one is green it says on the other is red it says shed I have no idea what shed means. I believe the furnace would work off gas or eletfic, but I'm not sure .csn any point me in the right direction to ware the igniter is located.
