2. Disconnecting Ribbon Cable from control and waiting at least 3 minutes to see if Code
recurs.
• If code recurs, problem is in the control. Replace control.
• If code does not recur problem is with the Key Panel.

Stuck key pad
May mean relay is
turned on.
Determine if problem is with the Key Panel or Control by:
1. Pushing CLEAR/OFF pad,
-F2-
Indicates that oven is over
temperature in one of the
following modes within either a
cooking or clean mode of
operation.
• Look for welded relay contacts. (Heating
elements on in off mode).
• Look for high resistance in the sensor circuit
due to high contact resistance (poor terminal
crimp, deformed terminals, loose connection
inside sensor tube) or intermittent solder joint.
• Electrical noise interference in the sensor
circuit (Ham radio, cordless phone, etc.).
• Control senses oven temperature
above 615°F with the door circuit in
the unlock mode.
• Control senses oven temperature
above 915°F with the door in the
door locked mode.
Replace control.
• Disconnect power to range. Disconnect sensor
connector from control.
• Measure sensor resistance at control connector
(take care not to damage terminals. Should read
1100Ω at room ambient (approx. 72°F).

Loss of door motor safety circuit.
NOTE: Connections can be intermittent due to a corrosive buildup between the
connection to the terminals, or by being bent by the insertion of a probe, etc.
Open or shorted sensor
(circuit). Could be a result of
contamination on terminals or
pinched wire in sensor circuit,
cold solder joint on control.
• Measure each sensor lead from connector block to ground. If shorted, look for pinched or
cut wire in sensor circuit.
• Check connector terminals - Look for deformed or corrosion on terminals. Repair or replace.
• If all above is ok replace control.
