TESTING THE OVEN RELAY BOARD
Element Testing
First access Diagnostic Mode. Once in Diagnostic Mode, the Technician can press a key to activate an element. The
element relay and the double line breaker(dlb) will close to complete a 240/208 VAC circuit through a specific element.
If the Oven Controller detects the current running through the closed circuit, OVEN ON will be illuminated on the cor-
responding display.
NOTE: Diagnostic Mode will end 2 minutes after last key stroke or when the CLEAR key is pressed.
* Note: The current sensor only detects the element circuits, not the Fans.

Ohm Testing Elements at Relay Board
This procedure will allow the service technician to ohm any of the elements directly at the relay board.
At the relay board, pull the wire off of the terminal DLBL/E11. This is done to keep from ohming the relay board. It
does not take the High Limit out of the equation, but if the technician DOES NOT get an ohm reading from the DLB
lead to all of the element leads, then, there is a problem with the High Limit.
To eliminate the High Limit when taking ohm readings, the MDL cover will need to be removed. Then, remove the
wire from High Limit switch that goes to the elements. Now, take the ohm reading from that wire at the High Limit to
the desired element wire at the relay board.
Right Convection Element: PR5/E5 to DLB/E11 wire
Left Convection Element: PR2/E5 to DLB/E11 wire
Outer Bake Element: PR4/E8 to DLB/E11 wire
Inner Bake Element: PR3/E6 to DLBL/E11 wire
Bake Stone Element: PR6/E10 to DLB/E11 wire
Broil Element: PR1/E4 to DLB/E11 wire
