a/c blowing air

guess the first step is to verify that the thermostat is in fact calling for cooling. by moving the fan switch to "on" you have the fan coming on 24/7, now you just have to make sure that if you turn the desired temp down that the A/C will run. most of those stats allow you to hit a hold button and that will over ride the program to whatever temp you choose to select. Obviously you would set that to below what the room temperature is to try the A/C out. If you know the model number of the thermostat we could research it for you, or you could take a picture of the thermostat and likely someone will recognize the model and proper set up.

Tstat pic RTH2310B

Pic keeps saying too large even when downsized

No temp tegistering when overidden. 28 o?

28 o????

T/S= thermostat - take pic of where wires hook in to T/S - need to see wire color & terminal letter======R -RH W - Y - G - others---

Can't tell much just looking at parts. Time to get your meter and tools out and start testing the system. Some troubleshooting will involve working with live electricity.

Ok I got a meter was hoping for a just change thermostat answer haha. Thank you very much

Why guess at the problem, when you could do some troubleshooting and diagnose the issue properly? It could be the thermostat, or several hundred other possible problems.

Yes I agree Im going to daignose may be a capasitor or other things. Where do you suggest I start first? Im thinking compressor capasitor

See if the units calling for cooling, if the contactor is pulling in, compressor amp draw, capacitance, outdoor fan motor amp draw, refrigerant pressures, SH, SC.

What was the fix??????

New capacitor
