A/C won't turn off regardless of thermostat setting ? GMP075-3 w/ 2 ton A/C

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 ? - Thanks

If you are able to shut the system down by using the thermostat as mentioned, the thermostat is either bad or the programming is messed up. Check the fan switch and turn it to "Auto".

Make sure the cooling system is not plugged up, poor coolant flow can make your engine run hot, and a plugged heater core will not allow heat in the cabin in the winter.

I have a 1998 Oldsmobile Bravada with automatic climate control that blows cold air in the winter and hot in the summer. The thermostat is working fine and it doesn't need flushed. There are no le


It sounds like the system is fried. Based on the description, it is just pulling in the outside air and not doing anything to heat or cool the flow. Unfortunately, this is a job for your preferred mechanic.

Furnance not heating


Make sure that the thermostat is set for the proper medium that you are using being gas or electric. Inside the cover of the thermostat should be a setting for either eletrical heat or gas heat. Set this switch for what your system is G for gas or E for eletric. This may solve your problem. Good Luck hope this helped you some

3 ton condensor and 2.5 air handler


I hate to use rules of thumb but 500sqft per ton depending on your windows and insulation. you are probably ok with a 2.5 ton however it will not work with a 3 ton outdoor unit as you have figured out. depending on how long that ac has been in you may want to replace it with a 2.5 ton due to the damage to the compressor valves because of the mis match. or if the indoor is newer and the original system may have been a 3 ton then i would replace the A/H. and be prepared to replace the outdoor if the valves are to far gone. If the trane is a new high effiency 2 and the goodman is just a 10 SEER you may be able to have a txv installed on the trane unit and a kickstart device outside. but only if its a high effiency but their again if the A/C fails you couldnt have a high effiency 3 ton you would have to drop down to 2.5,
