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.

ERC FAILURE CODES

FAILURE

CODE

Stuck key pad or transistor
failure. May mean relay is
turned on.

If code cannot be cancelled, replace
control.

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.).

Disconnect power to range.
Disconnect sensor connector at control.
Measure sensor resistance at control
connector (take care not to damage
terminals in block) - Should read
1100 ohms at room ambient (approx. 72  F).

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.
Check connector at sensor (remove sensor and carefully pull leads with connector into oven)
If all above is ok replace control.

Problem with door lock circuit such
as pinched wires between control
and door lock switches.

Check wiring and test operation of switches.
Perform resistance check.

Replace control.

Door motor safety switch transistor
failure

Loss of relay drive circuit

Press Clear/Off and reprogram control.
If -F5- code reappears, replace control.

Check sensor circuit.
Check lock circuit.
If all above check OK the F5 code can be a result of a momentary loss of power (DO
NOT REPLACE CONTROL AND LOCK.) Check lock circuit.

Could be result of contamination on
terminals, pinched harness lead, or cold
solder joint on control.

Open sensor (circuit) (over 2700
ohms) Shorted sensor (circuit)
(under 950 ohms)

Control senses oven temperature above
930  F with the door in the door locked mode.

the door circuit in the unlock mode.

Control senses oven
temperature above 630  F with

Indicates that oven is over
temperature in one of the following
modes within either a cooking or
clean mode of operation.
