- DDiana JosephSep 12, 2025
If the cool air temperature sensor is not working, check the sensor. For resistance reading, see Table 13.
What to do if my IBC AHU 1600 Air Handlers cool air temperature sensor is not working?
If the cool air temperature sensor is not working, check the sensor. For resistance reading, see Table 13.
What to do if my IBC AHU 1600 thermostat shows a fault?
If your thermostat is showing a fault, it could be due to simultaneous heating and cooling calls. Ensure that the heating and cooling leads from the Nest thermostat are not crossed. Also, there is a known issue with some thermostat models over 3 years old where the backing plate allows a short, signaling an unintended call for cooling.
What to do if my IBC Air Handlers fan has no RPM?
If there is no fan RPM detected, check if the fan is turning or disconnected. Also, check the fuse. Use a meter to verify that 120V is present on the external connection to the board. If 10V is not coming from the fan, it is not receiving 120V. Check the 10V signal on the web app.
What to do if the IBC Air Handlers door is open or there is no fan signal?
If you receive a 'Door Open / No Fan Signal' error, first check if the service door is open or if the door switch is faulty. Also, check if the harness is disconnected and if the fan is turning.
What to do if my IBC Air Handlers A/C is freezing?
If freezing is detected in the A/C coil, the coil needs to defrost. Refer to the manual for the air conditioner for details on how to prevent freezing.
What to do if my IBC AHU 1600 dehumidifier is freezing?
If freezing is detected in the dehumidifier appliance, the coil needs to defrost. Refer to the manual for the dehumidifier for details on how to prevent freezing.
What to do if my IBC AHU 1600 Air Handlers inlet temperature sensor is not working?
If the inlet temperature sensor is not working, check the sensor. For resistance reading, see Table 13.
What to do if my IBC AHU 1600 air out temperature sensor is not working?
If the air out temperature sensor is not working, check the sensor. For resistance reading, see Table 13.
What to do if my IBC AHU 1600 Air Handlers A/C temperature sensor is not working?
If the A/C temperature sensor is not working, check the sensor. For resistance reading, see Table 13.
What to do if my IBC AHU 1600 outdoor temperature sensor is not working?
If the outdoor temperature sensor is not working, check the sensor. For resistance reading, see Table 13.
