My furnace's draft motor never stops even after one full heating cycle, which it's supposed to stop!

This causes the pressure switch to stay closed even after the thermostat calls for heat the second time (after the initial heat cycle).

When I stop and start the main switch in my basement, the draft motor restarts thereby causing a full heat cycle to complete normally.

Is my control board malfunctioning or is there a relay or something that is preventing the draft motor from shutting down after one cycle??

Please please help - it's getting colder here.

I am having a similar problem with my York Stellar furnace. My inducer blower stays on but I do not even get one heat cyle, only the inducer turning and staying on. Did you solve your problem?

Well, somebody in a different forum suggested that the relay for the motor could be stuck. It's usually located on your control board but apparently, we cannot just replace only the relays. We need to replace the whole control board.

Try to tap on the relay to see if releases and shuts down the motor.

I hope anyone else can throw some more light on this.
