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. Sorry to hear about your issues with your furnace. In order to help, need you to do a couple things for me. I need the full model number (should be on a tag inside the unit). Also, there may be a flash code "legend" posted down near the board somewhere. If you can find, let me know what it says for a 2 flash code.
Could be bad ignitor or dirty flame sensor.
Are the burners lighting at all?
Do you have the Honeywell Smart valve on this unit or just a standard ignitor?
Does your gas valve look similar to this?
OK, that would not be the Honeywell Smart valve. If you hear hissing, but no orange glow from ignitor, then more than likely it is a burned out ignitor.
Yup, that was my next suggestion, look for a small crack!
There are many online sites that sell Ducane parts such as this one. You will need to replace the ignitor. Let me know if you have additional questions on this. Otherwise, good luck! Thanks for using Just Answer and please don't forget to rate my service as that's how experts get paid (thanks in advance for any bonus left). Otherwise experts work at their own time and expense. Feel free to post back with any additional questions.
