CHECK
1. Does the oven heat in any other
function?
2. Does the convection element
heat, in the convection bake
function?
3. Measure the voltage drop
between terminals P4 and P10
on the electronic oven control
board. Is the reading line to line
voltage?
1. Does the convection fan run, in
the convection bake function?
2. Measure the voltage drop
between terminals, P11 and P15
on the electronic oven control
board. Does the meter read
line to line voltage?
1. Check the wiring harness between
the electronic oven control board
and the interface board.
1. Check the wiring harness between
the electronic oven control board
and the interface board.
1. Is the fan blade restricted?
