Can I use a 1.5amp fuse in the fireman's switch? These 1.25's are so hard to find, and expensive

I got the new (aftermarket) control board in today. Good news the heater now turns on and the fuse is not blowing. Bad news is after running the startup cycle a few times the heater never fires. Fenwal is showing ignition lockout. Ignitor tested at 93.2 and the airflow switch goes from OL to 0.00 when I blow on the tube. I saw a video on here somewhere about all the tests to run through, those were the only two I remembered. I didn't smell gas at any point. I'll try to find that video again unless you guys have a good place to start looking. Thanks!
Another update! I replaced the aftermarket control board with the legit pentair 6 button control board. The heater works and the pool is 85 degrees and ready for our first pool party tomorrow! I can't thank you guys enough, you saved me thousands of dollars.
I still have one question. I bought the newer control board with the six button membrane as advised in a previous post. I thought it would come with the "flame" wire but it did not. Do i need this wire? If so does anybody have the part number? I can't seem to find it anywhere

If you are referring to the flame sense cable, this is the cable that goes between the Fenwal ICM and the heater control board. If you are only replacing the heater board/membrane pad, then this is not needed. You would need to change out the ICM in order to have this connection.
