Goodman A24-05 Evap motor
 
Hello all,
I have a Goodman A24-05. The Evaporator motor stops running or will not come on I am not sure what happens but the compressor will run and stay running. Since the blower motor is not running air threw the evaporator it freezes. I can take the lead off the BTDR or time delay relay and manually make the connection to the #3 terminal this starts the fan. I can put is back to the #1 terminal wait a few seconds and it starts up and starts pulling air. There is no set time when this happens it could be in the afternoon or it could be in the evening. The only way we notice it that the a/c stops cooling the house. Any Ideas? The coils are clean, and new filter.

Control board, stat, motor run capacitor or motor. Could be any one of those things when a motor sometimes comes on and sometimes does not.

I'd start with the run cap first.

DOC what is a STAT. By control board do you mean the thermostat? I cannot find a control board in the schematics anywhere. Thank for your replay

Thermostat, the thing on your wall that you switch onto fan, cool or heat that brings on or turns off the system.

I have a spare cap I will give it a whorl.

Don't go putting in any old capacitor. Check the size by way of number of the one that's on the motor and put in the exact same mfd cap.

I probably should've been more specific, many people don't understand our hvac slang.

fixed
 
I installed a new capacitor and that fix the not coming on problem. It seemed to run allot better as well. I also disconnected and isolated the leads to the heat coil and that made a world of difference. It cools the house far better I just need to see why the heater coils would come on when the A/C comes on. Wish me luck!

Heater ON when you call for cooling? Did you recently install a thermostat? Well before you had your problem? It maybe wired wrong. OR the Heater Relay maybe messed up some how and is being energized as cooling is being energized also. (weird don't know how that happens, unless someone from beginning wired the unit WRONG)
