What to do if the Dometic Control Unit digital display panel is not shown?
If the digital display panel of your Dometic Control Unit isn't showing, it could be due to the 8-pin display-cable plugs not making contact (unplugged, dirty, bent, or broken pins). With the power off at the circuit breaker, remove the connector and inspect it. If damaged, replace the connector or the entire display cable.
What to do if my Dometic Control Unit system will not start?
If your Dometic Control Unit system won't start, try the following: first, turn the circuit breaker on at the ship’s panel. Then, turn on the control. Check the wiring diagram and correct it if necessary. Ensure the power source (shore/generator) has the correct voltage, and verify wiring and terminals are properly sized and connected using a voltmeter to confirm the power at the unit matches the source. Finally, disconnect the power supply, open the electrical box, and make sure all connections are secure.
Why does my Dometic Control Unit system run continuously?
If your Dometic Control Unit system runs continuously, try raising or lowering the set point. Make sure all port holes and hatches are closed. Remember that seawater temperature directly affects the air conditioning unit’s efficiency; it can effectively cool in water up to 90°F (32.2°C) and heat (if the reverse cycle option is installed) in water as low as 40°F (4.4°C). Verify the display head location with criteria found in the control manual and install an alternate air sensor if necessary.
How to improve low airflow in my Dometic Control Unit?
To improve low airflow in your Dometic Control Unit, remove any obstructions in the return-air stream and clean the return-air filter and grille. Check for crushed or restricted ducting, ensuring it is as straight, smooth, and taut as possible. If the fan speed is set to Manual Low, press and release the Fan icon until the desired fan speed and airflow are reached. For automatic fan-speed control, press and release the Fan icon until the fan speed indicator shows AUTO.
Why is my Dometic Control Unit not heating?
If your Dometic Control Unit is not heating, try tapping the reversing valve lightly with a rubber mallet while the unit is in heat mode. Reprogram Reverses Fan Speed in Heat under General Settings.
What does “Low AC Voltage” mean on my Dometic Control Unit?
If your Dometic Control Unit displays “Low AC Voltage”, it means either the supply voltage is too low, or the voltage is improperly calibrated. Verify the power to the unit with a multimeter. Also, check that the Voltage Calibration under General Settings matches the voltage reading at the unit with a multimeter, and adjust the Voltage Calibration if necessary.
What does “Air Sensor Failure” mean on my Dometic Control Unit?
If your Dometic Control Unit displays “Air Sensor Failure”, it indicates a failed face plate air sensor, alternate air sensor, or display cable. Try unplugging the alternate air sensor if installed, or plug it in if it's not currently installed. You can also try another display cable. Also, check for damaged jack/socket in display head or on the circuit board. Visually inspect to see that pins inside the socket are not bent or corroded. Repair or replace the display or circuit board if needed.
What to do if my Dometic Control Unit switches to heat while in Cool Mode?
If your Dometic Control Unit switches to heat while in Cool Mode, it's likely due to the de-icing feature being enabled because of coil icing up. Reprogram the De-Ice Cycle under the DX settings.
Why is my Dometic Control Unit fan not running but the compressor is?
If the fan in your Dometic Control Unit is not running but the compressor is, it indicates a failed triac on the circuit board. Send it for repair or call a local service technician.
Why does the Dometic Control Unit fan run continuously when set to cycle with the compressor?
If the fan in your Dometic Control Unit runs continuously even though it is set to cycle with the compressor, it indicates a failed triac on the circuit board. Send the unit for repair or call a local service technician.
