Most searched Rheem furnace codes
| Code | Meaning |
|---|---|
| 11 | Failed ignition — the furnace control ran an ignition attempt and flame was not established and proved; the code is displayed after the first failed attempt and stays until ignition succeeds or the failures escalate to lockout. |
| 61 | Blower fault — blower unable to run. Critical: no operation in any mode. Rheem also declares 61 when the main limit has been open over 150 seconds during a heat call (the display then alternates 61 and 22): the control reads a limit that cannot re-close as a dead blower, because the blower should be carrying the heat away. A fourth dead-blower declaration in one heat call enters hard lockout. |
