“Quick Test” Mode for Electronic Range Control

Follow procedure below to use the quick test mode. Entries must be made within 32 seconds of each other or the control will exit the quick test mode.

1. Press and hold CANCEL and BROIL pads for 3 seconds. 2. Once the control has entered the “Quick Test” mode, release both pads. 3. Press each of the following pads indicated in the table below.

NOTE: First time the one of following pads are pressed it will activate the response. The second time the pad is pressed it will deactivate the response.

NOTE: This mode can only be entered within the first 5 minutes after power up.

NOTE: If the temperature sensor is greater than 400°F and the Quick Test mode will be disabled if the temperature sensor reaches 400°F while under test.

Display will indicate the following:

Description of Error Codes

Error diagnostic codes can only be viewed by entering the Diagnostic Code Display Mode. Each error code is four digits long and is created based on the following table.

Digit Description 1st Primary System: 1 – Local to the control circuit board 2nd 3rd 3 – Sensor or meat probe 4th 4 – Control input

9 – Door lock

Measurable: d – Diagnostic: measurable parameter

c – Control related, replace control

Secondary System: Sequential numbering

Oven Cavity: 1 – Upper oven (or single cavity oven)

2 – Lower oven

c – Control specific

Diagnostic Code Display Mode can be activated by pressing and holding the AUTOSET pad for 3 seconds at power-up. Diagnostic Code Display Mode can only be started while powering up the control.

NOTES:

1 “Action Taken” applies as long as the condition exists. If the condition goes away, the control recovers. 2 If there is a cook function or timer active, the function continues. The user cannot edit the function, and [Cancel] will cancel the cook

mode. 3 Flash rate: 0.2 seconds on, 0.1 second off. Pressing any key will clear the display until the fault clears and is re-triggered. 4 “Action Taken” applies until there is a POR (Power On Reset [“hard reset”]). 5 If the control believes the door is locked, it will attempt to unlock it when the function cancels and the cavity temperature cools. 6 Special conditions for latch faults (9dxx):

A known good unlock position is defined as when the unlock switch reads closed and lock switch reads open. A known good lock position is defined as when the unlock switch reads open and lock switch reads closed. A faulted switch means the switch input is reading an invalid state, neither open nor closed. Once a latch fault occurs, latch movement is disabled until there is a POR. An error tone will sound if a function requiring a

faulted latch is attempted. If at POR, the latch is not at a known good unlock position:

If the latch is at a good lock position, it will attempt to unlock when the RTD (Resistance Temperature Device) temperature is below 400°F.

If the latch is not at a good lock position, the control will fault.

If a latch fault occurs while the RTD is above the lock temperature, the latch will not try to move, but the fault is still logged to EEPROM after the first stage of detection.

The Display column for latch faults applies 1) If the latch was moving when the fault occurred; 2) If the latch is already in a known locked state when the fault occurs.

LOCK flashes after a fault is detected and until the unlocked position is achieved. The unlock position may be identified by a successful unlock switch closure, or as the result of timing when the unlock switch is not functioning properly.

If the last known good position was unlock (e.g. baking, or idle) and a latch fault occurs, the motor is never moved. The fault is logged to EEPROM and is not seen by the user.

The detection for latch faults is in two stages. The first stage is to let the control recover without moving the latch. After this:

If the latch was previously at a known good unlock position, the latch will not move and the control will fault.

If the control was previously in a known good lock position:

If the RTD is below 400°F, the latch will attempt to recover to it’s proper position (up to three revolutions). If it cannot, the control will fault and the latch will move to a calculated unlock position.

If the RTD is at or above 400°F, the control will fault. When the RTD cools to below 400°F, the control will attempt to recover to a good unlock position (up to three revolution). If it cannot, the control will fault and the latch will move to a calculated unlock position.

Note: If the unlock position cannot be found, this may result in a second fault, the first fault occurring when the latch request was locked, and the second when the latch request is unlocked.

If the latch is moving when the fault occurs, the control will bypass the first stage of detection and immediately try to find it’s proper position. If it cannot, the control will fault and the latch will move to a calculated unlock position.

Affected DLBs (Double Line Breaks) and loads are disabled during detection. If the control is in a known good unlock position and the lock switch becomes faulted:

The control will not fault. If a function requiring latch movement is attempted while the lock switch is faulted, the control will sound an error

tone and the function will be disabled.

If the control is in a known good lock position and the unlock switch becomes faulted: The control will not fault. After the function is canceled and unlock is attempted, the control will attempt to unlock the latch according to the procedures in these notes.
