    Goodman limit switch failure
    Hello,

    I have a goodman gm0150-5 furnace and above it is the ac coils I think. Yesterday I noticed that the inside furnace blower was not shutting off. I turned off the Thermostat completely, set the fan to auto and the thing is still running.. blowing air through my house... The outside Compressor for the AC is not running. I look inside on the board and it is flashing 4 times. "Open Limit" etc... I had a tech come in and he said it was a bad board, so he replaced it... and the same thing happeend to the new board... Then he told my my brand new condensate pump was not working and that shut off the outside unit. Needless to say I am unconvinced. Any ideas on what I can do here... I found those limit switches.. small circular things.. I have 4 of them... They look fine, I pressed the button on all of them.. it doesn't go anywhere... My Filters were cleaned 3 days ago, so I don't think that's it... Any ideas... I really need help... Someone also said that it is the pressure switch on the outside compressor...
