What to do if my Rinnai DONSR07B1 is not working?
- KKara PachecoAug 8, 2025
If your Rinnai Inverter isn't working, first, wait for the power to be restored in case of a power failure. If the power is off, turn it on. Check and replace the fuse if it's burned out. Replace the remote control batteries if they are dead. If the unit’s 3-minute protection has been activated, wait three minutes after restarting it. Finally, ensure the timer is turned off.
