Carrier Weathermaker 8000 help please
I've got a Carrier Weathermaker 8000 that began blowing cold today and I've been researching the problem online. It's throwing a code 33 and I want to try to manually reset the flame roll-out switch but I cannot for the life of me find it.

Also, I had it turned on and off several times and each time the blower would come on and nothing else would happen. I decided to try to clean the flame sensor and when I re-installed it and turned the furnace back on the igniter glowed this time and the small blower by the upper plenum kicked on but, I never got a flame. It shut down and when it cycled again only the main blower started blowing again.

Carrier circuit boards turn the blower on when the power is interupted and there's a call for heat.
Got a meter to check if there's 24 volts going to the gas valve after the ignitor glows?

Unfortunately no, I have no way to check that.
