What to do if Aprilaire E070 Dehumidifier shows E7 error?
If the Aprilaire Dehumidifier displays error code E7, empty the condensate pan and check the float switch connection at the control board. If you are not using a float switch, verify that a jumper is between the float switch terminals on the dehumidifier control board. If the problem persists, replace the float switch.
What does error E2 mean on my Aprilaire E070?
If the Aprilaire Dehumidifier displays error code E2, verify that the fan works and there is no blocked or restricted ductwork. If the fault persists, call Technical Support.
What does error E3 mean on my Aprilaire E070?
If the Aprilaire Dehumidifier displays error code E3, check connections between the Model 76 and the dehumidifier control board. Ensure terminals are fully inserted and secured. If connections are correct, turn off the dehumidifier and remove the Model 76. Reconnect the Model 76 to the control board with a short 4-wire cable. Turn the dehumidifier back on and increase the dryness level setting on the Model 76. If the dehumidifier turns on, the problem is with the wiring. If it doesn't, call Technical Support.
What does error E4 mean on my Aprilaire E070?
If the Aprilaire Dehumidifier displays error code E4, check the frost sensor connection at the power board, ensuring the terminal is fully seated. Remove the side access panel and verify the sensor is secured to the suction line. If connected and secured, reset the fault by cycling power. Turn the humidity setting down to make a dehumidification call. Let the fan and compressor run for 10-15 minutes, then enter diagnostic test mode by pressing the UP ARROW and MODE buttons for 3 seconds. Record the displayed values and call Technical Support.
What does error E5 mean on my Aprilaire E070 Dehumidifier?
If the Aprilaire Dehumidifier displays error code E5, check the high temperature sensor connection at the power board, ensuring the terminal is fully seated. Remove the side access panel and verify the sensor is not damaged and is connected to the refrigeration line coming from the compressor. If the sensor is connected and secured to the refrigeration line, contact Technical Support.
What does error E6 mean on my Aprilaire E070?
If the Aprilaire Dehumidifier displays error code E6, check the low temperature sensor connection at the power board. Remove the side access panel and verify the sensor is not damaged and is connected to the suction line. If the sensor is connected and secured to the refrigeration line, contact Technical Support.
What does error E1 mean on my Aprilaire Dehumidifier?
If the Aprilaire Dehumidifier displays error code E1, cycle power to clear the error code. If the error code reappears, replace the User Interface, Part No. 5475.
Why is my Aprilaire E070 producing hot air?
The air is reheated across the condenser coil, which results in a temperature rise between the inlet and outlet. This is normal operation for the Aprilaire Dehumidifier.
What to do if my Aprilaire Dehumidifier blower is running but with little or no airflow?
If the blower is running with little or no airflow, the pressure drop across the dehumidifier may be higher than 0.4"w.c. Try checking the Aprilaire Dehumidifier's air filter and wash or replace it. Also, inspect the ductwork for any blockages and clear them.
What to do if my Aprilaire E070 Dehumidifier is not draining properly?
If your Aprilaire Dehumidifier is not draining properly, verify that the unit is level. Also, check the drain line for any blockages and ensure it has a continuous downward slope.
Connecting the dehumidifier to a float switch or condensate pump overflow switch.
Connecting a remote control like the Model 76 for setting adjustment.
