My furnace was working yesterday and we did not turn it off, but it will not function today. I know there is electrical power at the unit; that there is gas supply; the filter is new; the inducer motor comes on when the thermostat is adjusted;but no flame appears. The inducer motor will remain running until I shut it off. Thank you.

Sounds like your hot surface iginitor is shot and needs to be replaced

Could be the pressure switch too. For a better understanding of your furnace, check the sticky at https://www.askmehelpdesk.com/heatin...ons-58313.html

This is Danny. Thanks for the responses. It turned out that the Thermostat was faulty. I replaced it and I am cozy and warm. Thank you.
