Hello, I have a goodman pc036-1b rev E. My issue is that when
I shut off my thermostat my fan keeps running.  I need to know 
if my unit has a blower resistor or what controls the output of 
the fan? If any one can give my any information on what I need
to replace of what to check. Thank You.  Tyler

do you mean your fan runs all the time . in cooling it should shut down right away in heat it will run for predetermined time. your stat is not in fan on?  let me know exactly what it is doing and try and tell you what i think is going on. thanks

I have my thermostat fan set on auto and my fan runs all the time.
When I set it to off it still stays running.
I tried unplugging the thermostat to see if it would shut off
and it stayed running. My thermostat looks like it is a LUX 1500.
Thanks.

does everything else work heat, cooling? if it does  not then you may have a bad control board. you still may have a board problem follow  the leads from your fan and see where the wires are staked on , you might see a stake on next to the other wires that are there. this empty stake on is probably a lower or higher speed move your wire there and then turn everything back on and see if the fan works better now.make sure power is off when you remove wires. i think it is the black wire you want to move. let me know if this helps it is a process of elimination.this is only  if you have a newer furnace if not you have a bad relay, on newer ones the relay is part of the comp. board.

Hey thanks alot for the help. I found the problem by poking around and
found that the contactors were welded shut from corrosion.
