Fans and Motors
First access diagnostic mode. Once in diagnostic mode, the technician can turn the oven control knob bezel or
press a key on the Electronic Control Housing to activate a fan or a motor. The fan and motor relays will close to
complete a 230 VAC circuit through a specific fan or motor. If the oven controller detects the functionality through
switches, the
**
CFH indicator light will be illuminated.
NOTE
:
Diagnostic mode will end 2 minutes after last key stroke or when the ENTER key is pressed.

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 DLB/E11. This is done to keep from ohming the relay board. It
does not take the Thermo limiter 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 Thermo Limiter.
Right Convection Element:
PR5/E9 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 DLB/E11 wire
Broil Element:
PR1/E4 to DLB/E11 wire
TO AVOID ELECTRICAL SHOCK, POWER TO THE UNIT MUST BE DISCONNECTED BEFORE PERFORMING
