THERMADOR Error Code Blank Display
Professional Ranges Models: PDR30/36/48…PRG30/36/48

ERROR CODE	DESCRIPTION	RESOLUTION
CODE Blank Display	No power to electronic 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 repair electronic range control (also called clock or ERC)

The control continuously keeps track of system criteria for control and also stove failings and reports a fault code when a system trouble is discovered. The control uses the ovens blue “on light” and oven “heating light” to report an identified fault code. The control will certainly continue to blink the lights in the suitable sequence as long as the fault exists.

Detection of a fault does not hinder the capability of the control to continue to operate if the mistake is not crucial for the intended procedure. As an example: If the range door lock is defective, the range will certainly remain to prepare because the fault would only stop the variety from self-cleaning.

HOW TO INTERPRET CODES
When a mistake takes place, the control will blink the blue oven “on light” and also heaven “home heating light” sequentially to indicate the mistake. The mistake codes have 2 numbers, these numbers are translated by the number of times the lights flash. The oven “on light” will certainly flash indicating the very first number, and the “home heating light” will flash suggesting the second number.

EXAMPLE:
Mistake E9 is … No Air conditioning Followers. The code is 43. The stove “on light” will certainly blink four times, then the “heating light” will blink 3 times, then time out. The series will after that duplicate as long as the mistake is present.

MISTAKE CODES FOR STOVES WITH DREEFS CONTROL
The complying with chart shows the error codes that can be shown in the Oven/Selector window throughout certain stove breakdowns. Some of the error messages can be removed by executing the following actions:

Transform the selector knob to OFF
2.”Modify” the stove by turning the selector handle slightly to the left (counterclockwise). This might stop the flashing message/beeping and also clear the home window.
For errors E1, E9, E11, E12 as well as E13, the power supply mosting likely to the also need to be shut off momentarily, and back on once more.
If a mistake continues to be shown when the selector switch is OFF, and also after trying to get rid of the display screen, as received actions 2 as well as 3, turn off the power going to the oven, as well as refer to the graph below to assist you locate 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.
