I have a question regard my goodman furnace on the "blink" (no pun intended). After discovering it to not be working properly I removed the front panel to find the blinking red light. It is blinking three times. I reviewed the troubleshooting guide to find 4 possibilities. I removed what I think is the pressure switch hose and blew it out to make sure it wasn't blocked with no resolution. I don't believe I have a blocked flu so am left with the pressure switch setpoint or loose wiring. Could someone give me advice on how to proceeed and if needed can I purchase a pressure switch replacement part and where might I obtain that. I thank anyone for their time

You may be able to temp jump the pressure switch contacts with a wire to see if that works. NOTE do not keep the jumper on if it works but replace the defective part.
