The air filter may be dirty, or the air return or supply grilles may be blocked. I understand some of that but not all of it or what the implications are. Assuming none of the actual troubleshooting issues are the cause (it's a brand new one-year-old furnace), does that mean it was too cold for too long and switched to high-heat mode, then locked itself out because of being in high-heat mode for too long? A little late, but one thing I haven’t seen anyone mention was if the gas pressures were set up correctly at install. If open less than 3 minutes status code #33 continues to flash until blower shuts off. Prospective Short Circuit (PSC) and Prospective Fault Current (PFC) are both intended to calculate the highest current that will stream within a fault loop path during the occurrence of an electrical flaw as needed by rules.. For more technical tips, visit edgetekhvac.com These technical tips are for licensed HVAC contractors only. This was done, but the problem persists. "Roll out" would be sensor usually near burner is getting too hot. Which means when they go bad, or the temperature gets too high they open the circuit. LIMIT CIRCUIT FAULT - This status code indicates the limit, or flame rollout switch is open or the furnace is operating in high-heat only mode due to 2 successive low heat limit trips.
