System test does nothing?

Hi there, my furnace appears to be functioning correctly switching between Stage 1 and 2 heat, but the “System Test” in the Advanced settings screen does not seem to trigger the furnace. I’ve left it for up to 10 minutes with no result. Any idea why this would be?

No clue, but mine did the same thing during setup, and even now - literally nothing. The system is functioning correctly on hot/cold though. I chalked it up to some kind of glitch…but it’s def strange that the system test just doesn’t work at all.
