I have Ohmeda 210 Ventilator , but it’s ventilator is not working

Here are some tips for troubleshooting an Ohmeda 210 ventilator that is not working due to a potential power supply issue:

• The Ohmeda 210 can operate on either AC or DC power. For AC, it requires a power input of 100-240VAC at 50/60Hz. For DC, it requires 11-15VDC.
• First, verify the ventilator is being powered - check that it is plugged in, the outlet has power, and any circuit breakers are not tripped.
• Inspect the power cable for damage and ensure it is securely plugged into the ventilator. Replace if damaged.
• Open the ventilator case and check that the internal power connector is properly attached to the main circuit board. Reseat if needed.
• Using a multimeter, check the voltage at the power input terminals or connectors on the main board. It should match the nameplate voltage for AC or DC operation.
• If the input voltage is correct, the issue may be a failed internal power supply module. This will need replacement.
• Also, inspect for any burnt/damaged components on the main board that could indicate a power surge issue.
• Check error codes for any power or supply-related alerts.
• As a temporary solution, try using an external DC power supply matched to the unit's input specs.

Document any error conditions and double-check the input voltage/connections to determine if the issue is internal or external to the ventilator.
