      If you're experiencing low pressure in the line of your Ingersoll-Rand Dehumidifier, several factors could be the cause. First, ice might be forming in the evaporator. You should check the probe and the electronic control board; if the problem continues, consider replacing them. You may need to contact a service center to check the gas charge. Alternatively, ensure the compressed air inlet/outlet is properly connected, the connecting tubing isn't clogged, and no valves are closed. Also, inspect the filter's condition. If air flows continuously through the condensate drainage, the drainage solenoid valve might be jammed; try cleaning or replacing it.

      For Ingersoll-Rand Dehumidifier model D12-480IN-A with low line pressure, first verify the condensate drainage times set on the electronic control board (C8 and C9). Then, check the signal from the control board. If the signal is continuous, it may be necessary to replace the control board. For model D600-950IN-A, inspect the no loss condensate drain and replace it if the issue persists.
