I have a carrier 58pav furnace, and it won't light.
Here is the sequence that I notice.
1st the furnace turn on and the fire kick on for 5 sec and then shut off
This happen for a second and third time.
I spoke to a HVAC friend (he is in another state) and he said sounds like you flame sensor. I replace the flame sensor (carrier OEM part) however, nothing change.
Then he said that the Ignitor maybe bad and I replace that also no luck.
Now I notice when I turn on the main switch the blower motor runs constantly, thing else happen, the blower motor does not stop running.
