Owners of the older Four Wheel campers with Atwood 8516-IV furnaces may be interested in the videos below.
Darren is working on an 8531-IV but it's very similar to our 8516-IV ones. In this case, it's mounted horizontally so those of us with vertically-mounted ones have to do some mental gymnastics to apply what we're seeing to our own furnaces. But the reward is seeing internal parts and getting disassembly tips, troubleshooting tips, and more....
In the two videos we learn...
- how to bypass the hard-to-reach high-limit switch (for testing)
- how to remove the exhaust vent
- how to bypass the thermostat at the furnace (for testing)
- where the ground connection is
- where the sail switch is and how it works
- where the control board LED is
- how to remove the control board carrier
- where the high-limit switch is (behind the motor)
- How to remove the gas valve/burner assembly
- how to replace the burner and the igniter (also known as the electrode)
- how to remove the combustion and main fan-wheels
- how to remove and replace the motor
