Turned on my furnace for the first time this year and it came on for a few minutes, then shut off. I changed/cleaned all the filters, and still no luck. Evidently, I should have been cleaning my flame sensor each year. I managed to go 15 years without cleaning it, but that was the culprit! The most difficult part is unscrewing the bracket to the sensor, but it's an easy fix, and will save you a lot of money by doing it yourself! Good luck! ;-)
1.Turn off breaker and gas, 2. Find your sensor and unscrew bracket. 3. Clean metal rod with rough end of kitchen sponge - dont scratch the metal. 4. Replace sensor and bracket , 5. Turn on power and gas.
