ERC ON BOARD DIAGNOSTIC TESTS
This test allows the Technician to energize various bake,
broil, and convection circuits. This test will also allow you to
energize the oven light and top panel light, and test key
panel responses.
How To Enter And Exit The Diagnostic Mode
To perform the ERC diagnostic tests, follow the steps
below:
How To Perform The Tests
The following tests allow you to quickly verify various ERC
and keypad functions. Listed below are the diagnostic tests
that can be performed directly from the ERC.
NOTE: If anyone of the keypads is pressed and held too
long the ERC may terminate the test mode, beep
continuously, or display F7.
➊
CONVECTION FAN MOTOR TEST - To perform this
test, press and hold the CONVECTION ROAST pad (for
the fan to energize the door must be closed). Quickly
open the door an listen for the convection fan motor. As
soon as you release the CONVECTON ROAST pad the fan
motor will deenergize. If the fan motor did not energize,
check the following: reconfirm that you have entered the
test mode correctly, check power and wiring connections to
the ERC, check for a bad fan motor, door switch or ERC.
➋
ENERGIZE BAKE CIRCUIT - To perform this test,
press BAKE then START and listen for the bake relay to
energize. CAUTION: If you hold the start pad in, you are
energizing the bake element. As soon as you release the
START pad the relay will deenergize. If the relay does not
energize, check the following: reconfirm that you have
entered the test mode correctly, check power and wiring
connections to the ERC, check for an open bake element
and lastly, suspect a faulty ERC.
➌
ENERGIZE BROIL CIRCUIT - To perform this test,
press BROIL then START and listen for the broil relay to
energize. CAUTION: if you hold the start pad in, you are
energizing the broil element. As soon as you release the
START pad the relay will deenergize. If the relay does not
energize, check the following: reconfirm that you have
entered the test mode corrrectly, check power and wiring
connections to the ERC, check for an open broil element,
and lastly, suspect a faulty ERC.
To initiate the ERC test mode, first remove power to
the appliance for approx. 8 seconds and then reapply
power.
Simultaneously press and hold the COOKING TIME
and DELAY START pads. While holding these two
pads press the number 8 pad. The word "tESt" will
appear in the ERC display. NOTE: If no keypad entry
is made within 5 minutes, the ERC test mode will
"time out".
To terminate the ERC test mode, press the CLEAR /
OFF key pad.
