What to do if MDG ATMe shows « STATE = FAIL»?
- RrobertnealJul 30, 2025
If the MDG Portable Generator displays a «STATE = FAIL» error, begin by checking the error messages. If the error is 'P. LOW', ensure the gas bottle is open. If using a CO bottle, check that the regulator isn't frozen and that the set pressure on the regulator is at 60 psi, 4.1 bar, or 410 kPa. Also, inspect the gas line and verify the reading of the pressure transducer «STATUS?PRESSURE». If the error is 'P. HIGH', verify the pressure transducer reading «STATUS?PRESSURE», ensure you're not using a Siphon CO bottle or liquid CO2, and restart the generator in case of a solenoid valve malfunction. If the error is 'HEATER', restart the generator and check the heating status «STATUS?STATE = xx% HEAT». If the heating value isn't progressing, check the fuses on the heater board and the voltage.
