If we go out and check the furnace it says it is normal(the blinking) if we take out the fuse for about 15-20min it works fine for a couple of days and then starts the same stuff all over... could this be a sensor or the thermostat?

A make and model of your system will help narrow down the problem.

I went out and looked at it and this is what it says... American Standard By Trane Company Model # YCC024F1LOBE Hope this helps

We recently went out and checked the lights again and it was blinking 5 times... meaning flamed sensed with gas vavle off~ so what does this mean and how do we fix it? Please help :(
