Outdoor Ambient Temperature Sensor Error

Open or short circuit of indoor room or evaporator temperature sensor.

Outdoor ambient temperature sensor error.

Open circuit or short circuit. Outdoor ambient temperature sensor malfunction. Outdoor ambient temperature sensor open circuit or short circuit. Open or short circuit of outdoor ambient or condenser temperature sensor.

Outdoor unit eeprom error. The ambient atc or outside air temperature sensor is an ntc negative temperature coefficient sensor that informs the semiautomatic automatic temperature control system of outside air temperature. The sensor detects an abnormally low or high outdoor ambient temperature. 43 communication failure with unit a 44 communication failure with unit b 45 communication failure with unit c 46 communication failure with unit d 47 unit a freeze protection 48 unit b freeze protection.

Check sensor is installed correctly on control. Unit continues to operate. Outdoor discharge air temperature sensor. The ntc sensor s resistance decreases as the outside air temperature increases.

Outdoor mid coil temperature sensor malfunction. Fan speed out of control. Indoor coil temperature sensor is open or shorted control board sets temp to 40 f. Cooling oil return cycle.

Outdoor coil temperature sensor is open or shorted sets temp to 20 f. F1 ol 2 time tl on outdoor ambient temperature sensor t4 open circuit or short f2 ol 3 time tl on circuit. Condenser coil temperature sensor t3 open circuit or short circuit. Check unit placement if the outdoor unit is in a high temperature area wait until the ambient.

The temperature sensors are mounted in a nema 4x enclosure with integral mounting tabs. System high pressure protection. Inverter module igbt over strong current protection. Use elec heat if available for heating.

84 outdoor ambient temperature fault. The mounting tabs can be used to surface or suspension mount the temperature sensors. Out unit low side value temperature sensor t2b open circuit or short. Temperature protection of.

Overvoltage or too low voltage protection. The series o 4 outside air temperature sensors are great for monitoring ambient air temperatures in outdoor applications. The computer uses this input along with other in car temperature. Open circuit or short circuit of compressor discharge temperature sensor t5.

Open circuit or short circuit of outdoor ambient temperature sensor t4. 24 installation and maintenance service manual 14 18k. System low pressure protection. Outdoor fan speed has been out of control.
