What causes a High Humidity Alarm on the Left or Right Tower of my HANKISON HBP Dehumidifier?
- A
  April HowardAug 21, 2025
  If the HANKISON Dehumidifier displays a High Humidity Alarm on either the Left or Right Tower, this could be due to a desiccant bed overload. Check the inlet air flow rate, temperature, and pressure; if the flow and temperature are higher than the design specifications, or the pressure is lower, this can overload the dryer. Another cause could be a damaged or defective dew point sensor or monitor, so examine the sensor for physical damage and check the monitor/sensor operation, replacing them as necessary. Finally, a loss of desiccant drying capacity might be the issue. Check the filter elements and drains for improper filtration causing desiccant contamination, and repair or replace as needed. It may also be that the desiccant's useful life has been exceeded.

What does it mean when my HANKISON Dehumidifier shows a Blower Motor Overload Alarm?
- P
  Patrick BartonAug 28, 2025
  If the HANKISON Dehumidifier displays a Blower Motor Overload Alarm, it could be due to restricted or blocked purge air flow. Check the intake filter on the blower for dirt; examine the filter element and clean or replace it. It could also be due to a line failure. Check the voltages and currents in the motor circuit.

What causes a Heater Over-Temperature Alarm on my HANKISON Dehumidifier?
- M
  mendozachristopherSep 1, 2025
  If the HANKISON Dehumidifier displays a Heater Over-Temperature Alarm, it could be due to insufficient purge gas flow. Check for purge blockage and temperature sensor failure. Another cause could be a temperature sensor failure; repair and replace as required.

What should I do if my HANKISON HBP Dehumidifier displays a Heater Low-Temperature Alarm?
- R
  Rachel MillerSep 4, 2025
  If the HANKISON Dehumidifier displays a Heater Low-Temperature Alarm, this could be due to a heating malfunction caused by heater failure or heater contactor failure. Replace the heater or heater contactor. It could also be due to a temperature sensor failure; repair and replace as required.

What does an Energy Management Under-Range or Over-Range Alarm on my HANKISON HBP Dehumidifier mean?
- M
  Matthew KlineSep 6, 2025
  If the HANKISON Dehumidifier displays an Energy Management Under-Range Alarm or Energy Management Over-Range Alarm, it might be due to an Energy Management sensor failure. Check the circuit for continuity and repair or replace as necessary.

How to troubleshoot indicator lights not illuminated on HANKISON HBP?
- B
  barnettcoreySep 8, 2025
  If the indicator lights on the HANKISON Dehumidifier are not illuminated, there could be several reasons. First, there might be no power to the unit, so check the voltage at the terminal board. Second, there might be a loss of power supply to (or at) the dryer’s electrical disconnect switch or breaker (customer supplied); check if the disconnect switch or breaker is closed, and if a tripped breaker or blown fuse is noted, investigate and remedy the cause. Third, a blown fuse could be the problem, so replace the fuse. Finally, there could be a board malfunction, so replace the board.

What does it mean when my HANKISON HBP Dehumidifier displays a Temperature Under-Range or Over-Range Alarm on the Left or Right Tower?
- M
  Maureen HoodSep 12, 2025
  If the HANKISON Dehumidifier shows a Temperature Under-Range or Temperature Over-Range Alarm on either the Left Tower or Right Tower, it could be due to a tower temperature sensor failure. An Under-Range alarm may indicate a short circuit on the sensor, while an Over-Range alarm may indicate an open circuit on the sensor. Check the temperature circuit for continuity and repair or replace as necessary.

What to do if my HANKISON HBP Dehumidifier displays a Dew Point Under-Range or Over-Range Alarm during regeneration?
- N
  Natasha WilliamsSep 13, 2025
  If the HANKISON Dehumidifier displays a Dew Point Under-Range or Dew Point Over-Range Alarm on either the Left Tower or Right Tower while regenerating, it could be due to an Energy Management temperature sensor (RTD4) failure. Check the temperature circuit for continuity and repair or replace as necessary.
