ERC Warnings and Failure Codes

The Electronic Range Control is capable of detecting
certain failures within the ERC, along with oven
temperature sensor and self clean door latch switch.

The warnings and failure codes which may appear on the
display:

If "d o o r" flashes in display, switch positions can only
be displayed in Quicktest mode by touching clean pad,
as shown below:

0

both switches are open

1

unlock switch closed, lock switch open

2

lock switch closed, unlock switch open

3

both switches are closed

Temperature Calibration Offset

The ERC incorporates ± 35°F. calibration offset
capabilities for the oven. This adjustment will not effect
the cleaning cycle temperature and will remain in
memory if power is interrupted. Follow the procedures as
listed to calibrate oven.

1. Press BAKE pad.
2. Press 

+

 o

 until an oven temperature greater than

500°F shows in display.

3. Immediately Press and hold BAKE pad until "00"

appears in display, approximately 5 seconds.

4. To decrease oven temperature (for cooler oven), press

r  

-

 until negative numbers appear.

Oven can be adjusted from -05° to -35° lower. To avoid

over-adjusting oven move temperature -5° each time.

5. To increase oven temperature (for a warmer oven)

press 

+

 o

 until positive number appear. Oven can be

set from 05° to 35° higher. To avoid over adjusting
oven, move temperature 5° each time.

6. Press OVEN CANCEL pad. Temperature adjustment

will be retained even through a power failure.

Function Switch Connection Check
Procedure

The Quick-Test mode can be used to verify relay
operation on the transformer/relay board. If the relay
engages (clicks) during Quick Test mode it is generally
operative.

Transformer/Relay Module

The relays for oven light, bake, broil, convection element,
convection fan and double line break are controlled by
approximately 24 VDC signal from the ERC. Input voltage
is 102 - 132 VAC.

Testing of the relays is with voltage applied to oven after
attaching voltmeter leads to appropriate terminals.

NOTE:  If bake or broil do not work the first test would be

the relay for double line break.

Double Line Break—K6

Drive voltage indicated at J1 connector Pins 1–3.

1. Turn off power to oven.
2. Attach voltmeter lead to E5 connector on relay board.
3. Attach voltmeter lead to E18 connector on relay

module.

4. Turn on power and touch bake, broil, or convection.
5. If 240 VAC is indicated the double line break relay is

closing. Otherwise, replace the transformer/relay
board.

Bake Relay—K4

Double line break relay okay.  Drive voltage at J1
connector Pins 3–5.

1. Turn off power to oven.
2. Attach voltmeter lead to E18 connector on relay

board.

3. Attach voltmeter lead to E11 (BK) connector on relay

module.

4. Turn on power and touch the bake pad.
5. If 240 VAC is indicated bake relay is operating.

Broil Relay—K5

Double line break relay okay.  Drive voltage at J1
connector Pins 3–6.

1. Turn off power to oven.
2. Attach voltmeter lead to E18 connector on relay

board.

3. Attach voltmeter lead to E12 (BR) connector on relay

module.

4. Turn on power and touch broil pad.
5. If 240 VAC is indicated broil relay is operating.

Testing Procedures

WARNING

!

To avoid the risk of electric shock, personal injury or
death, disconnect power before servicing, unless testing
requires it.
