When I arrived the house was hot I checked the outdoor unit it had no low voltage. Checked found the indoor board flashing 3 flashes saying fault from r32 sensor removed coil door and checked for a refrigerant leak, found the sensor had some liquid in it unhooked board still flashing causing fan motor to stay. I need to order indoor board and sensor. To get Air Conditioner running for homowner I hooked up outdoor transformer to back feed power to thermostat and unhooked legacy clip inside AHU. Cycled on AC checked volts, amps, temperature splits, refrigerant pressures including superheat and subcool, cycled system off to verify it would shut off we will order the indoor AHU board and r32 sensor and come and repair after parts come in. Homeowner would like a call letting her know when it will be.
