I have a 2 yr old high eff. furnace that from the start will not run if it has to run too long. always did the shut it off set it for no more that 3 degrees to get it back up and running.
Elec went out and furnace didn’t start burning up my inducer blower. sevice man could never find the problem so will not return my calls. why does this continue to happen and how can I fix it?
