Problem with Carrier 58MXA furnace...everything works, furnace won't come on...

Hi, and thanks for reading. My furnace stopped working last night. As mentioned it the title, everything seems to be working. I jumped the COM terminal to the test terminal and ran a component test. Surface ignitor came on, blowers came on, the test ran fine. I have no flashing error code currently. I have a Honeywell digital thermostat and I can hear the call for heat going through to the furnace. It goes from silent to a low hum when a call for heat is initiated. However, once the call for heat goes through, nothing happens, and the hum persists (I believe the hum is normal?). This just started last night, and I've been reading about resetting the limit switch and flame rollout switch. If no one has a suggestion on what could be wrong, could you at least point out where the flame rollout switch and limit switch is located and how to reset them manually. I can't find anything through google(images) and nothing is listed in my manual.

Thanks again for reading and much appreciation for any suggestions.
