1. If no power how do you know inducer is working?
LED code says you have an open limit switch. If switch does not close within a pre-set time, ( usually 2-3 minutes) the safety override turns unit off for about an hour, unless you reset it.
The read out of an open switch may not be precise, it doesn't actually check the switch, but diagnoses from symptom caused by open switch. Since inducer starts then stops, check that plastic tube to inducer and prssure sensor is connected at both ends.
I think other checks are going to need a muti-meter. Check this site, your problem is the first one addressed.
In mean time, I'll see if I can get a friendly admoderstrator to move this thread to HVAC forum, where the experts hang out, shooting the breeze, or trying to fix the breeze shooters.
