WHat is the error code you are getting? There are usually several limits in the circuit.One often overlooked is on blower housing on some Goodman models.

4 flashing reds, in manual it says it is thermal sensor High limit
Customer reply replied 6 months ago
are you calling me?
HVAC Technician: airheatman, HVAC Technician replied 6 months ago

OK do this. since you know where the primary is already. Follow the wires that attach until you locate all limits and try by passing each one until we find which is open.

Follow the entire limit circuit from the 12 pin plug where it leaves board and comes back to board.

if I'm correct I already did this there were 2 more attached on each side of the blower housing. I did bypass all and also check the sensor for continuity which both switches on blower gave me tone, however the primary switch under the burner rack shows as open, but even with all three switches bypassed I am still getting 4 flashing reds. is there additional sensors I am not aware of?
HVAC Technician: airheatman, HVAC Technician replied 6 months ago

Pri***** *****mit has to show continuity.How are you bypassing. Are you connecting wires together?

I made a jumper with the same type of terminals
Customer reply replied 6 months ago
ok,I'll go try that now Give me a few minutes to get back to you
HVAC Technician: airheatman, HVAC Technician replied 6 months ago

Take your time. If we show continuity try pushing wires into connector so they make contact with board when plugged in
