NO
Troubleshooting:
F6: EC TEMP (Electrical Compartment Temperature High)
YES
NO
Does the oven have
room to ventilate?
Required clearances:
Top: 5” (127 mm)
Sides: 2” (51 mm)
Is the oven in an area of moderate
temperature (120ºF [49ºC] or cooler)?
YES
Are five of the seven
cooling fans rotating?
(The other two side
fans are enabled only
when the microwave
circuit is on.)

items that are in close proximity.
Is the RTD open?
Using an Ohmmeter,
measure at the A7 and
A9 terminals on the
control board. RTD
should measure approxi-
mately 109 Ohms at
75
ºF (24ºC)
. Use Figure
34, page 29 to deter-
mine resistance readings
at other temperatures.
Replace the control board.
Replace the RTD.
