my furnace (RUUD) got a problem about the main burner, it is use a robertshaw 34NL-306A iginition control module.
the current status is : glow bar lite around 30 seconds then small flame light around 3-4 seconds but gas valve shut off instantly, the main burner not working.
3-times trail all the same results, is it means need to replace a new control module?
thanks for helps.

sounds like your flame sensor is not reciving a signal. Should look like a piece of wire in the flame path one wire coming off it.
