I think my blower motor fan relay is stuck in the on position. My thermostat easily disconnects from it's mounting bracking severing all connections. So, I pulled it as a means (my logic) if de-energizing the relay.
Should this have turned the fan motor off. It did not. Am I correct to believe the blower motor fan relay is stuck on?
Read on, if necessary; but, the above is my question.
Confession : This issue came about after I replaced the PSC motor (wouldn't reliable restart after replacing the run capacitor) with an Emerson 5532ET. I thought (wrongly) the "wire-for-wire" replacement marketing statement held true with the colors between old PSC and new ECM - it did not. So, I ended up smoking the 5532ET in a moment of brilliance with a bang. Well, a POP, really.
I over nighted another 5532ET and called an HVAC company who chose to help over the phone. After some Q&A, I connected the white & black and the replacement 5532ET runs and runs and runs and runs...
I suspect the relay arked & welded closed when things went wrong.
Some additional details, if needed.

Tapping the relay after shutting off the breakers did not produce any change after turning the breakers back on.
