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.

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.

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:

1. Turn the selector knob to OFF

2. “Tweak” the oven by turning the selector knob slightly to the left (counterclockwise). This may stop the flashing message/beeping and

3. For errors E1, E9, E11, E12 and E13, the power supply going to the even must be turned off momentarily, and back on again

4. 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 CODE NOTES

DESCRIPTION OF PROBLEM

Control board problem.

Cook or Clean mode runaway (temp >635 °F). Clean mode runaway (clean temp +32 °F). Open oven temperature sensor (>5000 Ω).

Shorted oven temperature sensor (<5000 Ω). Control board too cold, too hot, or defective. Control board problem. Illegal temperature display. Turn off oven and try again. Control board problem. Latch switch problem. Control board problem. CT oven – latch switch problem CT ovens – latch switch problem CT ovens – latch frozen or no power to latch motor.

CMT ovens – control board not converted (refer to page 3-7 for conversion data). Latch switch problem.

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.
