    Trane XE 1000 doesn't run or make sounds
    How do you start a new thread on this site? Anyway, I'll have to post it here then...
    I have a Trane xe 1000 outside AC unit that's not working and doesn't make a sound. I checked power to it and I'm getting 240 at the unit... So I replaced the Contactor and Capacitor and still nothing the fan turns freely too, so not blocked. I have more tests to do on it but It's raining out so I do them later just running this by you all to see if I can get some insight... Probable problems/questions... The whole AC unit is quiet... No hum from motor no sounds from compressor and worked fine last summer... Thermostat is a Hunter digital not the original and about 7 years old... I can turn on the heater with it but not AC... red blinking light on XE90 flashes about once per second, but writing on the control panel says that that's normal operation "No call for heat"... So I'm thinking there's nothing telling the AC unit to turn on after we turn on the Tstat so it might be bad... cheaper fix then having to call out a service tech.
    Does this make sense?
    Thanks in advance for your help

    You cannot just blindly replace parts. Check the outside contactor and see if you are getting 24 volts to the coil. Check to see if either terminal reads voltage to ground. Also, look at circuit board to see if LED is lit meaning you have control voltage. If you have no control voltage go to inside unit and check low voltage transformer to see if you have 24-30 volts. If not, you need a new one big enough for the load and with a circuit breaker on it. Check this out and write back.

I came home and the unit did not run. I checked the furnace and it showed that I needed to replace the thermostat. Now that that is done, it says that the heat is fine but to call for service. Is it freon? How do I know where to troubleshoot?
