Thermador Rng-Stv-Ovn Codes – How to fix? by HoustonAuthorizedRepair.com
THERMADOR Range/Stove/Oven Fault Codes starting with an E. If an error apears in the cook mode window.
Your oven is equipped with an extremely reliable and accurate electronic control. On the rare occasion that something occurs that causes a malfunction, an error message will appear in the oven selector window. Some errors (E1, E9, E11, E12, and E13) must be cleared by turning off the oven at the circuit breaker and then turning it back on. When an error remains displayed steadily in the off position, after attempting to clear the error, a service call is required. Have the error code available when you call for service. This will help service determine the problem.
| Error Code | NOTES | CHECK/REPAIR |
| E1 | C,E | Control board problem |
| E2 | K,G | Cook or clean mode runaway |
| E3 | A,H | Open oven temperature sensor (over 5000 ohms) |
| E4 | A,H | Shorted oven temperature sensor (under 500 ohms) |
| E5 | K,D | Control board too cold or too hot, or defective board. |
| E6 | C,J | Control board problem |
| E7 | A,I | Illegal temp display turn off and retry |
| E8 | A,D | Control board problem |
| E9 | A,E | Latch switch problems |
| E10 | B,D | Control board problem |
| E11 | A,F | CT oven; latch switch problem |
| E12 | A,E | CT oven; latch switch problem |
| E13 | A,C | CT ovens; latch froze or no power to latch motor CMT ovens; control board not converted |
| E14 | A,E | Latch switch problems |
| E15 | B,D | Control board problem |
Range/Stove/Oven Fault Codes Starting with F – How to fix? by HoustonAuthorizedRepair.com
| ERROR CODE | NOTE | CHECK REPAIR |
| F0 | Internal logic failure; cancel key supervision. Sounds alarm and resets to non-cook mode | Replace the electronic range control (also called clock or ERC) |
| F1 | Internal logic failure (monitoring function). Sounds alarm and inhibits cook modes | Replace the electronic range control (also called clock or ERC) |
| F2 | Temperature runaway detected (Bake/Broil: 600 – 700 F; Clean: 930 – 1000 degrees F). Sounds alarm and resets to non-cook mode. Check relay board for stuck contacts. Check oven temperature sensor for normal room temperature resistance (1085-1097 ohms at 75 degrees F). Check sensor wiring connectors for a loose or high resistance connection. Check electronic range control (also called clock or ERC) functions | Replace relay board if necessary. Replace oven temperature sensor if other components check normal. If failure repeats, replace electronic range control (also called clock or ERC) |
| F3 | Open circuit detected; oven temperature sensor. Check sensor for normal room temperature resistance (1085-1097 ohms at 75 degrees F). Check wires and connections between electronic range control (also called clock or ERC) and oven temperature sensor | Replace sensor if other components check normal. Replace electronic range control (also called clock or ERC) if fail code reoccurs |
| F4 | Short circuit detected; oven temperature sensor. Check sensor for normal room temperature resistance (1085-1097 ohms at 75 degrees F). Check wires between electronic range control (also called clock or ERC) and sensor. | Replace sensor if other components check normal. Replace electronic range control (also called clock or ERC) if fail code reoccurs |
| F7 | Function key shorted for over 16 seconds. Check for something pressing a key or preventing normal release of the key | Replace electronic range control (also called clock or ERC) if other components check normal |
| F8 | Internal logic failure; calibration. Alarm sounds and resets to non-cook mode. Check oven temperature sensor for normal room temperature resistance (1085-1097 ohms at 75 F). Check wires and connections between electronic range control (also called clock or ERC) and oven temperature sensor | Replace electronic range control (also called clock or ERC) and oven temperature sensor if other components check normal |
| F9 | Internal logic ailure; door latch supervision. Alarm sounds and resets to non-cook mode. If door is locked due to clean temperatures, disconnect power until door can be unlocked | Replace the electronic range control (also called clock or ERC) |
| Fd | Bake & Broil relay drives active simultaneously. Check relay board for damage: trace E6 to K2 & K3, and burned contacts K3 & K3 | Replace electronic range control (also called clock or ERC). Replace relay board if necessary |
| Blank Display | No power to lectronic range control (also called clock or ERC). Check oven light and cooktop dial lights (powered by L2 & L1, respectively). Check relay board transformer primary, E1 to E2 (140 ohms typical). If the transformer internal fuse is still OK, check output voltages, pins 9 – 8 (3.2 v.a.c.) and 7 – 6 (21 v.a.c.). Check clock functions after replacing relay board | If relay board transformer open (E1 to E2), replace relay board. If still no clock functions replace electronic range control (also called clock or ERC) |
