2.14 Ambient temperature too high/low 

Code displayed: 

ODU main board displays E037 (applicable to AA/AS/AX models). 

Fault detection method: 

Ambient temperature too high/low 

Fault identification conditions: ODU starts fault protection and fails to work 

properly

 

Possible causes: 

①

  Abnormal temperature sensor 

②

  Abnormal main board 

③

  External heat sources around ambient temperature sensor 

④

  Actual ambient temperature too high/low 

Troubleshooting: 

E037: Ambient temperature 

too high/low

Check whether ambient 

temperature sensor (TH01) is 

normal

Replace ambient 

temperature sensor

Ambient temperature is too 

high/low

No

Yes

Explain to customer 

that it is a kind of 

protection 

mechanism

No

Restart the unit

Check whether there 

are heat sources around the 

unit (especially around ambient 

temperature sensor)

Remove heat 

sources or install the 

unit at another place

Yes

No

Whether main board is normal 

(abnormal signal transmission)

Replace main board

Yes

No

Yes

 

 

2.15 System failure 

Code displayed: 

ODU main board displays E039 (applicable to AA/AS/AX models). 

Fault detection method: ODU nixie tubes display corresponding fault codes
