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 the cooling
fans rotating?
NO
Relocate oven to cooler
area.
YES
Check for obstructions in
the airflow and remove
them and clean the filter.
YES
Replace defective
component.
Troubleshooting:
F7: THERMO (RTD Open)
YES
NO
Is the RTD properly
connected to the control
board? (See page 63 for
schematic.)
NO
Correct wiring.
YES
NO
Correct connection.
Verify the RTD wires
are properly seated in
the connector.
Is the wire harness properly
connected? Check cooling fan
thermostat and cooling fans. (See
page 63 for schematic.)
Move oven to open area or remove
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 approximately
109 Ohms at 75
ºF
(24ºC)
. Use Figure 81,
page 42 to determine
resistance readings at other
temperatures.
Replace the I/O control
board (Sage).
Replace the RTD.
