Question about Goodman GMS90703BXA Heater
I just installed this furnace and I get the main burners to light for only about 3 seconds, I tried juming the pressure switch with the two grey wire and still the burners only stay on for a few seconds. The led light stays on steady for normal operation

Goodman vertical forced air 69,000 BTU gas furnace GMH950703BX
My gas furnace has a small to big problem. When the t-stat calls for heat the furnace clicks, The vent motor blower comes on, the ceramic electric igniter comes on, the gas to the burners start to flow then it like misfires" or “burps several times” like gas is there but not enough or something like that, hard to explain". Then the main gas source stops and the vent bower runs back up and ignition glows and tries the cycle again. The furnace then will start this process over and most of the time it takes like 40 times before it fires and 10% of the time runs normal. The light on the controller board (Emerson) stays solid lit. No blinking indicating a problem.
Steps to resolve:

Sounds like a problem with the flame rod. small silver rod that sits by end burner and detects a flame.
