Toni.noble@comcast.net homeowners email. Upon arrival homeowner showed me thermostat code A954-0 Smart thermostat, suction failure. Turned system off so thermistors would be the same temperature as outdoor temperature, Ohmd through outdoor suction line thermistor, using a 10k thermistor chart found that thermistor is reading the correct temperature. Checked placement of suction line thermistor and found it placed on the liquid line, this was causing the thermistor to read incorrect temperature when the system heats and flashing the thermostat code. Removed thermistor from liquid line and placed it on the suction line, insulated thermistor and secured all lose wires. Tested system in high heat, code is no longer flashing. Need to return to complete maintenance on system.
