What is model on indoor unit?
Looking for a manual Let me ask this have you replaced batteries in thermostat? Usually G and Y are made through thermostat on call for ac
Indoor fan is brought on by thermostat in cool mode in most cases.I am suspecting issue may be with thermostat.What is model on the thermostat you have?
Since you can urn fan to on and make it work I am pretty confident the issue is a bad thermostat.
The thermostat is like a light switch. Power comes to thermostat on RED to R.
On call for ac Red R, Green G and Y Yellow should all be energized through the thermostat.
When you turn fan to on you are manually closing r and G which should be done through thermostat in ac mode.
Compressor may have short cycled because of us messing with thermostat.It should come back on shortly
Do you see a wiring diagram on indoor unit? I have not been able to locate one
I am about to eave office for tonight, I will open to other experts and check tomorrow to see if you got this solved.
I see no one was able to help.I am back in office,The diagram appears to be for heat kit. I am trying to figure if your air handler may have a different relay for the blower for ac than fan only.Usuually s mentioned thermostat is what signals fan ,So I am still leaning to thermostat being problem
Hmm. You going to get a contactor today and replace it? If you have a meter you can verify 24v is actually getting to it on call for cool. If it is and not energizing we know that is bad
Definitely. When the points pit like that sometimes voltage sneaks through and sometimes it does not.Lets replace it and I am here everyday if you have any more issues.
