THERMADOR Error Code F4
Professional Ranges Models: PDR30/36/48…PRG30/36/48
| ERROR CODE | DESCRIPTION | RESOLUTION |
| CODE 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. Repair electronic range control (also called clock or ERC) if fail code reoccurs |
The control continually keeps track of system parameters for control and stove failings and reports a fault code when a system problem is detected. The control uses the stoves blue “on light” and oven “heating light” to report a spotted mistake code. The control will certainly remain to flash the lights in the proper series as long as the fault exists.
Discovery of a mistake does not impede the ability of the control to remain to function if the mistake is not vital for the designated procedure. As an example: If the variety door lock is defective, the range will certainly remain to cook given that the fault would only prevent the variety from self-cleaning.
HOW TO TRANSLATE CODES
When a mistake happens, the control will blink the blue stove “on light” and also heaven “home heating light” sequentially to suggest the fault. The fault codes have 2 numbers, these numbers are translated by the variety of times the lights flash. The oven “on light” will blink showing the initial number, and also the “home heating light” will certainly flash suggesting the second number.
INSTANCE:
Mistake E9 is … No Air conditioning Fans. The code is 43. The stove “on light” will certainly blink 4 times, then the “home heating light” will blink three times, after that time out. The sequence will then duplicate as long as the fault exists.
ERROR CODES FOR OVENS WITH DREEFS CONTROL
The following graph reveals the mistake codes that can be presented in the Oven/Selector window during certain oven malfunctions. Some of the error messages can be gotten rid of by carrying out the following actions:
- Turn the selector handle to OFF
2.”Fine-tune” the oven by transforming the selector handle a little to the left (counterclockwise). This may stop the flashing message/beeping and clear the home window. - For mistakes E1, E9, E11, E12 and E13, the power supply mosting likely to the even should be switched off momentarily, and also back on once more.
- If a mistake continues to be displayed when the selector button is OFF, and after trying to get rid of the display, as received steps 2 as well as 3, shut off the power going to the stove, as well as refer to the graph listed below to help you find the trouble.
| 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. |
