ERC ON BOARD DIAGNOSTIC TESTS
This test allows the Technician to energize the bake and broil relays (listen for A click), use the ovens onboard temperature sensing and control system to measure oven temperature (sensor, connector and ERC diagnosis) and lastly it allows you to test keypanel input responses.
HOW TO ENTER AND EXIT THE DIAGNOSTIC MODE
To perform the ERC diagnostic tests, follow the steps below:
1.To initiate the ERC test mode, first remove power to the appliance for approx. 8 seconds and then reapply power.
2.Simultaneously press the COOKING TIME, DELAY START and number 8 pads. 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".
3.To terminate the ERC test mode, press the CLEAR / OFF key pad.
HOW TO PERFORM THE TESTS
The following tests allow you to quickly varify various ERC and keypanel functions. Listed below are four common diagnostic tests that can be made directly from the ERC.
1 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 circuit. 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, and lastly suspect a faulty ERC. NOTE: when performing this test, the glowbar will be energized as long as you hold in the start pad.
2ENERGIZE BROIL RELAY - 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 circuit. As soon as you release the START pad the relay will deenergize. If the broil relay does not energize, check the following: reconfirm
that you have entered the test mode correctly, check power and wiring connections to the ERC, and lastly suspect a faulty ERC. NOTE: when performing this test, the glowbar will be energized as long as you hold in the start pad.
3SENSOR TEST - To perform this test, press and hold the COOKING TIME pad or DELAY START pad (vaies by model). The oven temperature will show in the display. NOTE: oven temperatures below 100°F. will show as 100°F. If the temperature showing in the display is not correct then suspect the following: calibration, sensor, sensor connection, or ERC.
4NUMERIC KEY PADS TEST - To perform proper numeric key panel input responses, press any numbered key pad and hold it in for approximately 5 seconds; the number you are pressing will show in the ERC display. If it does not, reconfirm that you have entered the test mode correctly, check wiring connections to the ERC and keypanel, and lastly confirm shorted or open key pad by performing the Key Panel test on page 10.
