System won't turn off with thermosatat temp adjustment ( Goodman system)

Furnace is a Goodman GMP-075-3 1998
A/C condensing unit is a Goodamn 2 ton 10 SEER unit 1998


It is now the middle of a hot summer . The system is cooling fine but a
problem has developed where the A/C and fan stays on regardless of the
thermostat setting . I can only tun it off by placing the switch
thermostat in the off position (between heat and cool ) . I suspect that
is probably a bad control board or thermostat . How do i diagnosis this
further (and repair) ? - Thanks

You pick up the yellow pages, and look under "air conditioning contractors",
then call one.

Noon air is right. You will save time, money, and family discomfort by
having a qualified HVAC service person diagnose and repair your system
rather than mucking if up yourself.

It does sound like a mis-wire rather than a failed part though. If it turns
off when you switch the thermostat to "off", then something's a miss with
the wiring. [Unless your FAN is in the 'on' position rather than 'auto' -]
