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 failures as well as reports a mistake code when a system issue is detected. The control utilizes the stoves blue “on light” as well as oven “heating light” to report a spotted fault code. The control will certainly continue to blink the lights in the proper series as long as the fault exists.
Detection of a fault does not hinder the capacity of the control to remain to operate if the fault is not crucial for the intended procedure. For example: If the variety door lock is defective, the variety will continue to cook since the fault would just stop the variety from self-cleaning.
HOW TO INTERPRET CODES
When a fault occurs, the control will blink heaven stove “on light” and the Blue “heating light” sequentially to indicate the mistake. The mistake codes have two numbers, these numbers are analyzed by the number of times the lights flash. The oven “on light” will blink indicating the very first number, as well as the “heating light” will certainly blink indicating the 2nd number.
INSTANCE:
Mistake E9 is … No Cooling Followers. The code is 43. The stove “on light” will certainly flash 4 times, after that the “home heating light” will certainly blink three times, then time out. The sequence will after that repeat as long as the mistake is present.
MISTAKE CODES FOR STOVES WITH DREEFS CONTROL
The following chart shows the error codes that can be presented in the Oven/Selector home window during details stove malfunctions. Some of the error messages can be cleared by performing the complying with actions:
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. |
