Found that transformer, replaced and tested unit to find out that gas valve cycles on and off like it either has a bad flame sensor or pressure switch however, this is not the case. It appears that the gas valve loses power, but nothing else is triggering it. The gas valve was recently replaced and it appears that the furnace control board is bad. The blower motor Has a bad bearing and motor does not freely spin. The unit is 23 years old and for this reason with the current condition and everything wrong, it is strongly recommended to consider upgrading unit. Based on our findings today, it might be time to think about getting a brand new system.
