What to do if my Enviro HPP 06 motor fails to start?
- B
  Breanna WoodAug 9, 2025
  If your Enviro Air Conditioner motor isn't starting, there could be several reasons. The CFM adjustment voltage may be too high (above 10.0 VDC) or too low (below 5.0 VDC). Adjust the CFM voltage accordingly. For units shipped before April 2011, ensure the voltage is between 5.1 VDC and 9.9 VDC. Also, check that the ECM cables are properly connected to the motor by unplugging and reinstalling them. If the ECM cables are damaged, replace them. A mechanical failure could also be the cause, so check if the motor rotates freely. In case of electrical failure, consider replacing the motor. Lastly, oxidized or sulfidized fan relay contacts can prevent the motor from starting, so replace the fan relay if necessary.

Why does my Enviro HPP 06 Air Conditioner motor surge?
- C
  Christopher JonesAug 16, 2025
  If your Enviro Air Conditioner motor is surging, it could be due to a couple of reasons. The fan CFM adjustment voltage might be outside the range of the Fan Calibration Curve; in this case, adjust the voltage to a value within the curve's range. Another possibility is that the external static pressure (ESP) is too high. Check for any obstructions in the discharge and ensure the coil fins are clean. Make sure the plenum opening is unobstructed and that the filter, if present, isn't dirty and doesn't restrict airflow.
