I woke this morning to 58 degree home when furnace set at 72, it had shut down in the middle of the night. I couldn't figure out anything to try other than the circuit breaker, which I did and the furnace fired up. My carrier 58sta090 tries to start, it will ignite three burners, fourth won't ignite. It will try this three times then kick to code 14. I have to then turn furnace off, go to circuit breaker and reset breaker - turn furnace back on and it will start. I normally get code 33 when it's trying to ignite. Filter is good. Most of the time it ignites all four burners, but it happens quite often that it doesn't light all four then kicks out. I'm not sure if its time to call in expert or if there is something else I should try. Any recommendations would be good.
