Question about Heating & Cooling
Filter was dirty and i clean it and put back but still wouldn't stay on
7 blinks means unit is locked out it will stay locked out for one hour then try to light again it will try two times before lock out. Possible causes. Low gas pressure, Faulty gas valve, Faulty hot surface ignition or burner problem may cause this. Most common is Hot surface igniter.

A constant red light (not blinking) indicates that the thermostat is not calling for heat. Of course you know it is but just to be safe, jump out R and W on the board. If it continues to do the same as you indicated, replace the board.

I Also have the same and other problems with my furnace model # GDS80703AXBB. First the LED kept blinking 4 times and I too jumped the primary limit, that didn't kelp. After several attemps I moved the wires going to the circut board and everything starting working again. After a week It stopped working again, so I pulled the plug out of the circut board checked all wires for for a bad connection plugged it back in. Now the LED blinks 6 times again I move the wires. Then the LED blinks 3 times. Then the transformer burns out. I have burned out 2 transformers and I have ordered a new circut board.

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??

In the path of the flame on the last burner that starts, there will be a small rod. That rod is the flame sensor. Take a scrub pad and polish it. Also check the electrical connection that goes back to the circuit board. Disconnect any ground wire from the circuit board to furnace cabinet, sand it and replace it.

sounds like it is the pressure switch try jumping it out on some models you fool the heater in too working or see if the tubes are blocked , there should be some codes on the front panel or the fan panel
