I had the company that installed my furnace come over today as they recommend every two years having it cleaned and next month would be two years. Well they came and did the job I guess the flame rod was caked pretty good in carbon so they cleaned it and had the furnace running. After they left I turned it off. Well its a cold day here so I went to turn it back on and it didn't light the first time? the gas came on but didn't ignite? so I left it for a few seconds and the gas came back on ignited fine. I called him and he told me that's normal that sometimes it wont catch on the first try and that it sometimes could take 3 times to ignite.
I trust them as they are great and my whole family has been using them for close to 30 years. The furnace has a 10 year parts and warranty so if they have to come back it wont cost me anything. its just weird as it has never taken two times for it to ignite. But I guess they know what there talking about.
Two days ago it was 100f and today it struggled to get into the mid 30's
Just curious though, Is it normal for it to sometimes take more then once to ignite?
