would need to hear a recording.
Thanks.would need to hear a recording.
Thanks.Your inducer is failing.
The trane part is expensive.
Thanks,Just turn the fan on or a/c and see if there are any bad noises. a/c is a better test, runs at a higher speed than continuous fan.
The main blower is in the lower compartment assuming the furnace is an upflow. The inducer is in the upper compartment.
The inducer should a long time, it should have to be replaced only once over the 20 +/- year life of the furnace.
