I have a Concord 90 plus propane gas furnace. In the past couple of weeks, there have been times when it lit OK, but then went out after 2-4 seconds. It may light OK the second time it tries or it may kick out after three tries. According to the trouble code label, a little green lit flashes six times indicating "system lockout". The furnace is approx 8 years old. What may be the problem? Thanks

Clean your flame sensor. If you can't find it take a pic and post will try to locate it for you
