Energy saving technologies assuring the peak efficiency and optimal comfort underlie the operation of Dometic air conditioners. Reduction of air humidity and maintenance of the temperature are their most important functions.
Dometic offers air conditioners of all classes of power. Due to presence of Dometic air conditioner troubleshooting or Dometic rv air conditioner troubleshooting systems, depending on the class, you will be able to quickly detect a possible malfunction and able to remove it.
Dometic air conditioner Fault code & Function desciptions
|Fault condition||Digital display code||Note|
|Room temperature sensor fault||E1||Call for service|
|Evaporator sensor fault||E2||Call for service|

Preventing cold air function:
When heat mode is selected, the internal fan will not start until the air within the air conditioner is heated. This is to prevent cold air blowing into the living space during start up.
Blowing surplus heat function:
In heating mode, the fan will continue to run for approximately 60 seconds after the OFF button is pressed.
At low ambient temperatures approximately -5°C the heating mode will periodically enter a defrosting mode.
In heating mode, detection of the evaparator temperature IPT, when IPT
when IPT >= 60°C, compressor is not working.
when IPT <= 48°C, compressor will be contiunted working.
when 48°C < IPT ≥ 55°C The compressor will keep the original state.
IPT:evaparator sensor temperature.
OPT:condenser sensor temperature.
