Furnace not working first time out.
Furnace not working first time out. It was a hundred degrees when I did the walkthrough.I dont remember if the guy showed me the operation. I have a suburban furnace. Not sure if I need to do anythin...

OK .....click at t-stat (has DC power) but no fan/no nothing at furnace
Then you need to check at furnace for an 'on/off---circuit breaker switch'
It has a manual reset.
(Should be 12V DC at switch....check with meter)
From that switch DC goes to circuit board to a 'blower control circuit' and from there to fan motor.
Pull connectors on circuit board....check for any bent pins and then reconnect making sure connectors go on tight.
Try to fire off furnace again.
No go.
Then WARRANTY
