The owner manual says this flashing means the furnace is in a lockout mode. I tried to shut down the power to the furnace for about 5 minutes and started again as suggested. But the blower fan comes on and runs for about 30 seconds and nothing happens. This continues for another couple of times and then a complete halt to operations. Can anyone assist with this problem? Appreciate

check the circuit board for a push in type automotive looking fuse,,,,is it blown ?if so replace and get back to us
