pressing the CANCEL/OFF keypad. The code
will return if the user attempts to use the range
before the failure has been corrected.
Corrective Action
1. Disconnect the power for at least 30-seconds.
2. Reapply power and observe for 5-minutes.
3. If failure remains, remove power, replace the control,
and perform step 2.
1. Measure the sensor value between the connector pins.
You should measure between 1000Ω @32˚F and 2697Ω
@ 900˚F. If the measurement does not correlate to real
temperature, replace the sensor, and reference steps 3
through 5.
Also measure from the sensor connector to the sensor
casing for a possible short.
2. Trace the wires and connectors to the sensor from the
control, then from the sensor back to the control.If all
connections are okay and there is no wire damage,
reference step 3 through 5.
3. Disconnect the power for at least 30-seconds.
4. Reapply power and observe for a minimum of 1-minute.
5. If failure remains, replace the control, and then repeat
step 4.
