clips should be in place.
F.
Place a weighted thermo-couple in the center of the oven cavity.
G.
Set oven temperature control to 350*F. Oven temperature should reach 350*F in 10 minutes.
H.
Cycle oven 5 times: Average 3rd, 4th and 5th cycles. Temperature is acceptable if the
average is 350*F -15F +25*F.
TEMPERATURE;
I.
For convection test lower temperature to 325*F. Pre heat oven with convection fan on.
TEMPERATURE:
