I am facing a unique problem with my central air system.
Make of the system is Goodman.
For the past two months, my central air system\\s blower and compressor
would not shut off when I place the thermostat to off position.
I called a specialist from Sears. He studied at my system for more
than 2 hours and could not diagonize the problem. But he suggested to
try changing the furnace circuit board.
I ordered a new circuit board and replaced it myself. Same problem.
Blower / Compressor won't shut-off.
Then, I read in the internet that the cooling part of my thermostat
might be broken. So, I changed my thermostat. Same problem continues.
(my old thermostat was white-rodgers and my new one is Honeywell)
Now I am running out of options.
Please help me.
Thanks in advance.
