OPERATION AND SERVICE PROCEDURES

Electronic Range Control (ERC) (Models w/Two Piece Control)

TO AVOID THE RISK OF ELECTRIC SHOCK, PERSONAL INJURY OR DEATH DISCONNECT POWER BEFORE SERVICING, UNLESS TESTING REQUIRES IT.

If a higher resistance is indicated disconnect the intercon- nect harness from the sensor and recheck the sensor resistance to assure that the problem is in the sensor and not in the interconnect harness or due to a bad connection. The following table shows the corresponding resistance for different oven temperatures.

tests and Figure 37.) The sensor resistance can also be checked by removing the J2 connector and insert- ing the ohmmeter leads into the connector plug terminals.

6.To remove the ERC, disconnect the J1 and J2 connectors and remove the four (4) ERC mounting screws.

ERC VOLTAGE TESTS

1.Partially remove the ERC from the control panel. Follow the ERC Removal Procedures, Steps 1 - 5.

2.To check the input voltage for the vacuum fluorescent display, insert the AC voltmeter leads into the J1 connector at pins J1-1 and J1-2, and turn on power to the range.

1.Shut off power to the range.

2.Remove the "TIME/TEMP. SET" knob by pulling it off of the control shaft.

3.Remove the eight (8) function control buttons by pulling them out of the ERC.

4.Remove the two (2) control panel lower trim mounting screws. Carefully pull the lower trim and control panel glass towards the front of the range and remove trim and glass.

5.Remove the four (4) backguard control panel mount- ing screws (two (2) each side) and pull the panel assembly forward. The ERC input and relay drive voltages can now be tested at the ERC J1 connector with power applied to the range. (See ERC voltage

RC231002 Rev. 3

Figure 25 - Electronic Range Control Pin Identification A voltage reading of approximately 3.2 VAC should be indicated. If no voltage is indicated, check for loose connections, open wire (s) and relay/power supply circuit board output voltage at pins J1-7 and J1-8 on the relay board.

3.To check the input voltage that the ERC uses to drive the bake/broil relays, insert your AC voltmeter leads into the J1 connector pins J1-3 and J1-4. A voltage reading of approximately 20.3 VAC should be indi- cated. If no voltage or a low voltage is indicated, check for the input supply voltage at pins J1-3 and J1- 4 (Step 3).

4.To check the bake relay drive voltage, insert your DC voltmeter leads into the J1 connector at pins J1-9 and J1-5, and program the ERC for a bake operation.
