Have HVAC Questions? Ask an HVAC Expert for Answers
Hi, I'm Tim and I'm an HVAC expert here to assist you with your questions. Please provide all information I request as it makes it more difficult to troubleshoot something when I'm not there onsite. Essentially, you become my eyes and ears. Thanks for the opportunity to help. At the end of our dialog, you will have a chance to rate my service, but please wait until we are finished and you're satisfied you have all the information you need. What happens at the furnace when you call for heat? Can you tell me step by step what the furnace does? Do the burners light, even if only briefly?

If you have HSI (hot surface ignition), there should be a flame rod in by the burners. May look like this. It is usually removed with one screw. Shine up the metal part with steel wool or emery cloth, then replace.
In by the burners. On the opposite end of the ignitor that glows orange and lights the burners.
Also, please recheck that model number. I am not pulling anything up with that model.
Since I don't have a model number that is pulling anything up, I am trying some of the basics. I did not say cleaning flame sensor would definitely be the solution. We are just eliminating possibilities here. If you can tell me which switch "pops" and shuts unit down, this will help us get closer to a solution.
OK, I can certainly understand your decision to call a pro. Even though we were just getting started in trying some things. Let me know the outcome.
