21)
Attach tie wraps to maintain a neat appearance and to prevent wires from catching in
places that could cause a short. Be sure the temperature probe wires do not contact the
door latch.
22)
Carefully place the front control panel back into position. Make sure that none of the wire
connections on the new temperature control board contact any internal parts of the oven.
Replace the four screws previously removed.
23)
Replace the side access cover and screws previously removed.
24)
Turn the shaft on the temperature control fully counterclockwise. Install the control knob
so the indicator line points to the top right corner of “C” on the overlay. Lightly tighten one
set screw to hold the knob in place for test.
25)
Restore power to the oven.
26)
Place a probe from a digital thermometer inside the oven next to the new temperature
probe.
27)
Turn the oven on and make sure the blower and the light work. The amber
temperature lamp should come on. This will go out after a few minutes and the oven will
be warm (not hot).
28)
Set the blower speed on the “low” setting and turn the temperature knob to 350º F. Allow
the oven to cycle at least three times. Record the temperature when you hear the relay
turn off and when you hear the relay turn on again. There should be a 10º difference
between the two. The middle temperature between those two is the true oven
temperature.
29)
If the line on the knob does not point to that temperature, CAREFULLY loosen the set
screw. Pull the knob straight out (do not turn the shaft) and replace it straight on with the
line pointing at the actual oven temperature. Tighten one set screw and repeat the
temperature measurement to make sure the knob points to the true oven temperature.
Adjust as needed.
30)
Once the knob is set at the correct temperature, tighten both set screws to prevent any
further movement.
31)
Increase the temperature to 425º F and verify that the oven cycles properly at that
temperature.
