Turned the thermostat on, the air handler turned on but the condenser did not. The condenser was off on a hard lock out. Reset the board and the condenser started. Checked the pressures. The system was low on refrigerant. Added 3lb 4 oz R410 to the system, also the air filter was plugged. Washed the filter. The discharge temp is 90* in the kitchen. The system is operating properly. Recommend adding UV dye to the system to see where a leak may be.
