Servicing safeguards: To avoid personal injury and/or property damage, it is important that safe servicing practices be observed at all times. Examples of safe service practices are listed below but are not limited to the following:
- Never attempt a product repair if you have any doubts as to your ability to complete the repair in a safe and satisfactory manner.
- Before servicing or removing an appliance:
- Disconnect power to the appliance.
- Turn off the gas / LP supply.
- Turn off the water supply.
- Never interfere with the proper operation of any safety device.
- Use only genuine factory replacement parts as substitutions may interfere with compliances to home safety codes or standards.
- It is extremely important that all safety ground connections be reestablished prior to the completion of the service call. Failure to do so will result in a hazardous condition being created.
- Prior to returning the appliance back into active service, ensure the following:
- All electrical connections are correct and secure.
- Electrical leads are properly dressed and secured away from sharp edges, high temperature components and moving parts.
- All non-insulated electrical terminals, connectors, heaters, etc. are adequately spaced away from metal parts or panels.
- All safety grounds (both internal and external) are correctly and securely connected.
- All access panels are properly and securely reassembled.
The control continuously monitors system parameters for control and oven failures and reports a fault code when a system problem is detected. The control utilizes the ovens blue “on light” and oven “heating light” to report a detected fault code. The control will continue to flash the lights in the appropriate sequence as long as the fault exists.
Detection of a fault does not hinder the ability of the control to continue to function if the fault is not critical for the intended operation. For example: If the range door latch is inoperative, the range will continue to cook since the fault would only prevent the range from self-cleaning.
Thermador Error Code Light Sequence Code Description
E1 22 EEPROM ERROR
E2 01 CONTROL NOT CALIBRATED
E3 10 SENSOR OPEN
E4 12 SENSOR SHORTED
E5 21 POTENTIONMETER FAILURE
E6 32 OVER TEMPERATURE-COOKING
E7 23 OVER TEMPERATURE-CLEANING
E9 43 NO COOLING FANS
E11 44 DOOR LATCH FAULT
E12 11 EXP. BOARD NOT CONNECTED
E13 13 VCC LIFT OFF ERROR
E14 55 SELECTOR SWITCH ERROR
How To Interpret Codes
When a fault occurs, the control will flash the blue oven “on light” and the Blue “heating light” sequentially to indicate the fault. The fault codes have two numbers, these numbers are interpreted by the number of times the lights flash. The oven “on light” will flash indicating the first number, and the “heating light” will flash indicating the second number.
Example: Error E9 is…. No Cooling Fans. The code is 43. The oven “on light” will flash four times, then the “heating light” will flash three times, then pause. The sequence will then repeat as long as the fault is present.
Thermador Error Codes For Ovens With Dreefs Control
The following chart shows the error codes that can be displayed in the Oven/Selector window during specific oven malfunctions. Some of the error messages can be cleared by performing the following steps:- Turn the selector knob to OFF.
- “Tweak” the oven by turning the selector knob slightly to the left (counterclockwise). This may stop the flashing message/beeping and clear the window.
- For errors E1, E9, E11, E12 and E13, the power supply going to the even must be turned off momentarily, and back on again.
- If an error remains displayed when the selector switch is OFF, and after attempting to clear the display, as shown in steps 2 and 3, turn off the power going to the oven, and refer to the chart below to help you find the problem.
| ERROR MESSAGE | ERROR CODE NOTES | DESCRIPTION OF PROBLEM |
|---|---|---|
| E1 | C & E | Control board problem. |
| E2 | G & K | Cook or Clean mode runaway (temp >635 F). Clean mode runaway (clean temp +32 F). |
| E3 | A & H | Open oven temperature sensor (>5000 ). |
| E4 | A & H | Shorted oven temperature sensor (<5000 ). |
| E5 | K& D | Control board too cold, too hot, or defective. |
| E6 | C & J | Control board problem. |
| E7 | A & I | Illegal temperature display. Turn off oven and try again. |
| E8 | A & D | Control board problem. |
| E9 | A & E | Latch switch problem. |
| E10 | B & D | Control board problem. |
| E11 | A & F | CT oven – latch switch problem |
| E12 | A & E | CT ovens – latch switch problem |
| E13 | A & C | CT ovens – latch frozen or no power to latch motor. CMT ovens – control board not converted (refer to page 3-7 for conversion data). |
| E14 | A & E | Latch switch problem. |
| E15 | B & D | Control board problem. |
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.
Range Error Codes – Additional Information
| CODE | DESCRIPTION | WHEN CHECKED |
|---|---|---|
| F1 | Meat probe not there or incorrect | During Test / use |
| F2 | Oven sensor not correct | During Test / use |
| F3 | Warming sensor not correct | During Test / use |
| Door Latch Error | Door latch problem | During self-clean |
| ERROR | Temp. reaches 585 degrees F. Display shows “CONTACT SERVICE” and beeps. The beep can be stopped with touching cancel zone, but display will stay up with program locked until main power is removed for a minimum of 5 seconds. If the temperature continues to rise (due to stuck relay) the latch will lock at 600 degrees F | During any cooking mode |
