Action

1. Check the connection between the sensor board and control board.

2. If connection okay, replace sensor board, Part No. S1-5460.

Cycle Power

1. Verify that the fan works, the backflow damper swings freely and there is no blocked or restricted ductwork.

2. If the fault persists, call Technical Support.

Communication Loss

Insufficient Capacity 1. Check the frost sensor connection at the power board. Terminal should be fully seated on the power board pins.

2. Remove the side access panel and verify that the sensor is secured to the suction line.

3. If the sensor is connected and secured to the refrigeration line proceed to the next step.

4. Reset the fault by cycling power to the dehumidifier.

5. Turn the humidity setting down (below room/home humidity level) to make a dehumidification call.

6. Allow the fan and compressor to run for approximately 10-15 minutes and then enter diagnostic test mode by simultaneously pressing the UP ARROW and MODE buttons for 3 seconds. The LCD will display the temperature measured by the internal sensor while also displaying AIR SAMPLING and ON, the humidity measured by the internal sensor while also displaying %RH and ON, and the frost sensor temperature while also displaying ON. Scroll through these values and by using the

UP/DOWN arrow buttons.

7. Record values and call Technical Support.

High Temperature

Thermistor Failure

1. Check connections between S1-DDHC76 and dehumidifier control board. Terminals should be fully inserted and secured in the control board and S1-DDHC76 control terminals.

2. If connections are correct and secure, turn off the dehumidifier and remove the S1-DDHC76.

Use a short section of 4-wire cable to reconnect the S1-DDHC76 to the control board. Turn the dehumidifier back on and increase the dryness level setting on the S1-DDHC76. If the dehumidifier turns on, the problem is with the wiring between the dehumidifier and control.

3. If the dehumidifier does not turn on, call Technical Support.

Low Temperature

Thermistor Failure

1. Check the high temperature sensor connection at the power board. Terminal should be fully seated on the power board pins.

2. Remove the side access panel and verify the sensor is not damaged and connected to the refrigeration line coming from the compressor.

3. If the sensor is connected and secured to the refrigeration line, it may need to be replaced with

Part No. S1-5456 – contact Technical Support to confirm.

1. Check the low temperature sensor connection at the power board.

2. Remove the side access panel and verify the sensor is not damaged and connected to the suction line.

3. If the sensor is connected and secured to the refrigeration line, it may need to be replaced with

Part No. S1-5455 – contact Technical Support to confirm.

1. Empty the condensate pan.

2. Check the float switch connection at the control board.

3. If not using a float switch, verify jumper is between float switch terminals on dehumidifier control board.

4. If the problem persists, replace the float switch.

1. Verify all ductwork is properly sealed.

2. If no signs of leak points, contact Technical Support.

Outdoor

Temperature Sensor

Open or Shorted

1. Check the sensor connection at the power board.

2. Remove the wires from the terminals and measure the resistance. A short circuit will have a resistance very close to 0 Ohms and an open circuit will have a very very high resistance. The table at right can be used to approximate the resistance based on outdoor temperature.

3. If the sensor is not reading correctly, replace the sensor,

Part No. S1-8052.

• Allow sufficient clearance for filter removal and to prevent airflow obstruction

• Electrical service access will require the removal of the side panel shown. Allow sufficient space for service on this side of the unit.

• If locating the unit in an attic or crawl space, an

S1-DDHC76 control mounted in the living space is recommended.

• For attic installations, it is recommended that the dehumidifier be suspended.

• Always install the dehumidifier in a condensate pan when locating in or over a finished space.
