American Standard Freedom 80 furnace
i've got two problems with this furnace. one-- it keeps shutting down on me. like it's shutting it's power off to itself. it's not breaking the breaker, the LED light is off and everything. i jiggle the circuit board around and it kicks back on. i'm thinkin it's something wrong with the board. and/or a loose wire.

two-- when it is working, occationally the flame will go out (i do have propane) and the LED light will flash 4 times fast then pause for a few seconds, then flash 4 more, etc. it's will still be blowing but it continues to try and light. i've replaced the glo plug already. and i don't have a list of what the LED flashes mean, on the back of my panel either. model number--ADD080C945C3 serial number--L394M891G
i think it's a 1993. and if andbody has the complete LED light flahes list.
