Atwood 8500-IV furnace problem

Some thermostats have adjustable "range" - i.e., it can be set to raise the temp 1 degree, two degrees, or three. It may be sensitive enough that a slight change in temp could cause problems. It is no cost to open it or take the cover off and find out.

That's a very good suggestion. If the "range" is set to low it could cause the cycling. That furnace should not be instantaneously cycling on and off. That could possibly make something get to hot and make the circuit breaker blow.
