Rinnai Error Code 34 Troubleshooting

The reason that a Rinnai error code 34 requires a qualified technician to rectify the issue is due to the hot water heater having to be thoroughly inspected and sections pulled apart – the systems thermistor wiring harness will need to be checked for any loose or damaged connections leading back to the PC board.

If this is all in order the next step would be to remove the thermistor entirely from the fan motor housing to be able to check the resistance readings and correct if any issues.

If the readings are all correct then the gas connections and pressures, clearances, dip switches, burner and venting will be inspected and remedy where required.

If no issues are found and the Rinnai fault code 34 still remains then the only option left would be the replace the thermistor.

As you can see the process can become quite involved depending where the problem lies.

If an unqualified contractor attempted to repair a Rinnai error code 34 they could cause more damage in the process as well as causing a safety concern to your home.

Any repairs made by an unqualified contractor will also void your hot water heaters warranty terms and they will be uninsured which leaves you in a lot of trouble should something go wrong.
