Mobile home gas heater Model DGAA56BDTB. We recently bought

Customer Question

Mobile home gas heater Model DGAA56BDTB . We recently bought Mobile home. Heater is 6+ yrs old. I replaced the two filters. Later, a beep came on and the code light says - the upper chamber is fowled. The circular foam filter to the chamber fell apart when I touched it. The previous owners may never have done any service to the unit.
How do I access the upper unit and clean it?

was the code referring to a limit trip? And does the unit run the blower nonstop?

Or is the unit running ok but just shows error code?
