Did a preventative maintenance on a train gas furnace. Clean the flame sensor. Did an amperage draw on the inducer motor and the blower motor the inducer motor was a little high for my liking but was in the range of the furnace specs. Cleaned out the burner compartment and the blower housing. Did a combustion test the CO was seven and the O2 was 14. Cleaned out the drain for the high-efficiency furnace and made sure the condensate pump was working.M#TUX1B080A9421AB s#7165SH67G
