such as the generator or AC mains plug, a problem with the distribution panel, problem at the outlet or
plug, or a problem with the wiring. There is no problem with EasyStart.
If there is power and after 10 seconds there is no lights inside EasyStart, EasyStart must be
returned for service. Follow the instructions at

Trouble light definitions
Unexpected current
This fault can indicate a problem during the learning process or a problem with EasyStart. If re-
learning does not fix the problem, contact Micro-Air for possible servicing of EasyStart.
Over current
Compressor run current has exceeded the maximum value allowed by the device or the
maximum value calculated during the learning process. In many cases re-learning EasyStart can clear this
problem. This can also be caused by a failing compressor, poor condenser flow, or bad run capacitor.
Power interruption / Short cycle timer
In addition to the short cycle delay this indication provides, it also provides indication of a short
duration power interruption. Compressors will stall after only a few lost cycles of AC energy creating a
huge load when power is restored. EasyStart has built in fault detection for this condition so breakers
and generators do not overload and trip. EasyStart will shut down the compressor when detected for a
short cycle delay (three or five minutes), then automatically restart the compressor following this delay.
Open compressor overload
The compressor overload in the common winding connection is open. This indicates poor
air/water flow (i.e. overheated condenser) or a problem with the compressor.
Stall
EasyStart has detected that the compressor cannot start or has reduced its speed and will stall.
This fault can be caused by an improperly sized or bad start capacitor in some systems
. Note: RV systems
are universal and do not have problems related to the start capacitor sizing. Stalling is usually a wiring
related issue in these systems.
This is also a problem that can be caused by the output voltage collapse
