Dometic OD-5001 power vent fan not running

Use this when water flow is on but the OD-5001 heater does not come on and the power vent fan is not running.

Owner-safe checklist

• Turn the water heater off if it does not start normally.
• Record whether water flow was present and whether the fan was silent.
• Check only normal RV power controls and breaker state from the user panel.
• Do not open the appliance or control enclosure; call service for internal fuse or board checks.
