THERMADOR Error Code F9
Professional Ranges Models: PDR30/36/48…PRG30/36/48
| ERROR CODE | DESCRIPTION | RESOLUTION |
| CODE F9 | Internal logic failure; 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 | Repair the electronic range control (also called clock or ERC) |
The control continually keeps an eye on system criteria for control and oven failures as well as reports a mistake code when a system issue is discovered. The control uses the stoves blue “on light” as well as oven “home heating light” to report a found fault code. The control will certainly continue to flash the lights in the appropriate series as long as the fault exists.
Discovery of a mistake does not impede the capability of the control to continue to operate if the mistake is not critical for the intended operation. As an example: If the range door lock is inoperative, the variety will remain to prepare considering that the fault would only prevent the range from self-cleaning.
HOW TO INTERPRET CODES
When a mistake takes place, the control will certainly blink heaven stove “on light” and heaven “heating light” sequentially to suggest the fault. The fault codes have two numbers, these numbers are interpreted by the variety of times the lights flash. The oven “on light” will certainly blink showing the very first number, and also the “home heating light” will blink suggesting the 2nd number.
EXAMPLE:
Mistake E9 is … No Air conditioning Fans. The code is 43. The oven “on light” will flash 4 times, then the “home heating light” will certainly flash 3 times, then time out. The sequence will certainly after that repeat as long as the fault exists.
MISTAKE CODES FOR STOVES WITH DREEFS CONTROL
The adhering to chart reveals the mistake codes that can be shown in the Oven/Selector window during specific stove breakdowns. Several of the error messages can be cleared by performing the following actions:
- Transform the selector handle to OFF
2.”Fine-tune” the stove by transforming the selector knob somewhat to the left (counterclockwise). This may quit the flashing message/beeping as well as clear the home window. - For errors E1, E9, E11, E12 and E13, the power supply mosting likely to the also must be turned off for a short while, and also back on once more.
- If a mistake continues to be shown when the selector button is OFF, as well as after attempting to get rid of the display screen, as received actions 2 and 3, switch off the power mosting likely to the oven, as well as describe the chart listed below to assist you discover the issue.
| 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) |
| ERROR CODE | NOTES |
| A | Turns heat off on the failed oven only; microwave not affected. |
| B | Turns all heat off; microwave not affected. |
| C | Disables the CLEAN mode in both ovens; allows COOK and microwave. |
| D | Error will remain in the display until oven is repaired and powered back up. No error tones. |
| E | Turning the oven off stops the error and flashing display. Can tweak away the error code. Error is redisplayed only if the selector is turned to CLEAN. |
| F | Tweaking clears to “—“ for retry. |
| G | Clears when the oven temperature is less then the runaway temperature with the selector switch off. |
| H | Can be cancelled by tweaking if a good sensor is detected. |
| I | Cleared with a mode change. |
| J | Can be tweaked away for immediate retry. User must unlatch and delete the “—“ to try to relatch the door. |
| K | Turns heat and microwave off. |
| L | If two switches show a locked door, then E13 and LOCK are permanent in the display (in all modes). If the two switches show an open door, tweak away the E13 error message. |
