Hi, I have an older,15 years or so, Bryant gas furnace. I woke up this AM and my digital thermostat was blank, no reading, and the fan was running continually with no heat :( . Me jumping to conclusions went and bought a new thermostat :) . Same results, no heat and fan running. It is late so I am done messing with it today. Would greatly appreciate any help. Am i wrong to think that the transformer went out? Thanks for any help you can give!!!!
