Airflow switches rarely fail. Check tubing to switch and that heat exchanger isn't cracked.

Is your ac and Furnace controlled from same tstat? if so they might be linked thru Air conditioner relay if so when furnace calls  for heat it senses thru Ac then Ac will send signal to Furnace    my unit actually you hear click of ac when furnace I turned on  :twocents:

Check all the electrical ground connection. They corrode over time. When my heater doesn't start it's usually the ground on the ckt board that needs cleaning.
