Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am HVAC Guru an extremely experienced tech on the site and I try to get to as many customers as I can. I just picked up your question now. Answer: That means the vent has exceeded temperature...Push the red reset button on the switch. 2. Check the flue temperature during operation using a combustion analyzer. 3. Replace the vent limit switch if faulty. 4. Verify the combustion drain if clear and draining properly. 5. Visually inspect the target wall to see if it is intact. All I ask is please use the Star Rating Link at the top of your page before leaving, tips are greatly appreciated so thank you very much for using this service. If you have any other questions just post back to me here anytime!
