Noritz NRC Series Code 760
Remote controller communication fault. The remote controller in the house and the circuit board in the heater have lost contact. Noritz checks the connection between them and looks for damage to the controller or the board. This is the one code in the table where the display window shows nothing at all — Noritz prints "No Display" in that column — because the fault is on the controller side.
Part replacementThe verdict
Replace a part
Usually the wiring run between the controller and the unit rather than either end of it, and it is the cheapest fault in this table to find. The heater itself is fine; you have simply lost the ability to set it.
Typical cost: $0–$500

What you can safely check
- Cut the power for a minute and restore it.
- Check the controller cable where it is accessible for pinching, staples, or damage — particularly if any work has been done in that wall recently.
- If it stays, book a service call.
Frequently asked questions
Why does the display window show nothing for this code?
Because the display window is on the circuit board and the board is working — it is the link to the remote controller that has failed. Noritz prints "No Display" in the display-window column for 760 for exactly that reason.
