I have a trane heater that sometimes starts with just the blower, cold air, for 30 seconds or so, then off. next I hear the ignition and induction fan, then after 10 or so seconds normal operation with warm air. I just notice it maybe 1 out of 10 starts.
What's with that false start?
Looking at the last paperwork I have, the models numbers recorded are:
TUD120R960K5, 2TIB3060A1000AA, (not very clear handwriting so some of this may be off )
Thanks in advance for your help, much appreciated
