Does anyone have this furance with the conversion motor in it? When my unit was new and it called for heat the low pressure burner would come on and the high pressure wouldn't come on unless more heat(2-3 degrees) above set point was called for. My unit coded a 31 and as I reset I noticed the high pressure burner comes on first and then the low follows. Is this normal with a conversion kit motor??

I have this unit with the conversion motor on it. When new the unit would cycle the low pressure burner would come in and the high would come on only it the thermostat was calling for more than 2-3 degrees above room temp. Now my unit coded a 31 and I noticed the high comes on first followed by the low. Is this normal?
