Suburban 42000 will cycle perfectly at set-temps above 68*. When the thermostat is set at lower temps, it will reach set temperature (55*) shuts down as it should but not re-start when the temperature falls. I then turn off the thermostat, turn it back on, furnace fires right up again.
Summary... furnace runs flawlessly at higher set temperatures, not the lower set temps.
Just don't want to replace parts that are not needed! Thank you all in advance for your responses.
I know, just leave it at the higher temps right!!!
