Problem: carrier package gas electric unit produce no heat.

Insight: only inducer fan motor is running when it's calling for heat.

Solution: check dc voltage on the Hall effect sensor terminals while the inducer motor is running. Got no voltage, Bad sensor. Replaced the Hall effect sensor, turned heat on. Heat is working now.
