THERMADOR Error Code F8
Professional Ranges Models: PDR30/36/48…PRG30/36/48
| ERROR CODE | DESCRIPTION | RESOLUTION |
| CODE 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 | Repair electronic range control (also called clock or ERC) and oven temperature sensor if other components check normal |
The control constantly keeps an eye on system parameters for control and oven failings as well as reports a mistake code when a system issue is detected. The control utilizes the stoves blue “on light” and oven “home heating light” to report a detected fault code. The control will continue to blink the lights in the proper sequence as long as the mistake exists.
Detection of a mistake does not impede the capability of the control to remain to function if the fault is not crucial for the desired procedure. As an example: If the range door latch is inoperative, the range will certainly continue to prepare given that the fault would only protect against the array from self-cleaning.
HOW TO TRANSLATE CODES
When a fault occurs, the control will certainly blink heaven oven “on light” as well as heaven “home heating light” sequentially to show the fault. The mistake codes have 2 numbers, these numbers are translated by the variety of times the lights blink. The stove “on light” will certainly blink showing the very first number, and the “heating light” will certainly blink indicating the 2nd number.
EXAMPLE:
Error E9 is … No Air conditioning Followers. The code is 43. The oven “on light” will certainly flash 4 times, then the “home heating light” will flash 3 times, then time out. The sequence will then repeat as long as the mistake exists.
MISTAKE CODES FOR STOVES WITH DREEFS CONTROL
The complying with chart reveals the mistake codes that can be presented in the Oven/Selector window throughout details stove breakdowns. Several of the error messages can be cleared by doing the adhering to actions:
- Turn the selector handle to OFF
2.”Tweak” the stove by turning the selector knob slightly to the left (counterclockwise). This may stop the blinking message/beeping as well as clear the window. - For errors E1, E9, E11, E12 and E13, the power supply mosting likely to the also should be shut off for a short time, and back on once more.
- If a mistake remains shown when the selector button is OFF, and after trying to remove the display screen, as received actions 2 and also 3, turn off the power mosting likely to the oven, as well as refer to the graph listed below to aid you find the problem.
| 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. |
