Question about Heating & Cooling

There is a vacuum sensor on most units tied from the exhaust gas fan to the sensor. Does the unit try to start? If the unit's exhaust fails to pull the switch it will turn off after about 30-45 sec after starting. "IT" thinks it's not exhausting and stops to keep from overheating. Do you have this exhaust fan and rubber hose to sensor? Can you see if that fan is turning on start?

I am not familliar with that proticular model but continous flash could be reversed polarity. That is where I would start.

I have a goodman GMP075-3 that won't turn on. I think it is the pressure switch since I do not have a vent blockage. What is a venter and where can I find it??

Inspect both the intake and exhaust pipes for blockage or debris. Inspect the small tubes that go from your combustion fan to the pressure switch and the tube that goes from the fan to the condensate drain. They all should be clean and dry. Inspect the combustion fan to see if it spins without it scraping on the housing or it may be filled with water or debris. Last, check the air filter and clean or replace.
