EBME Forums Forums Maintenance Technical Assistance OHMEDA 7800 VENT ERROR 21

Hi guys. I have an Ohmeda 7800 vent, it is showing Error 21 Vent Failure.
Can someone explain this problem & its solution.
Thanks in advance.
Regards

Since the service manual for the Ohmeda 7800 is big (18.2 MB),I uploaded it to 4shared so you can download it from there.

According to the service manual, error 21 implies that you have to replace the control board. Page 6-7 (in the pdf file is page 153).

I hope this helps you

Thanks reindiaz.
Lots of thanks.
I am downloading now.
Lets see.
