Emile for Model Number gr478lxpq0 range When I use convection it takes a super long time for the oven to get up to temperature. But when I use regular bake it heats up just fine. Was thinking it was the circular heating element...what are thoughts?
Answer Emil;e, you will need to check the resistance of the convection heating element. Turn the power off and access the back of the oven to where you can see the two terminals of the element for the convection heater. Pull one wire off the element, (it doesn't matter which one), set your multimeter to ohms of resistance and touch one lead to the bare terminal, the other lead to the other terminal and take a reading. At 1600 watts, the reading should be about 36 ohms, plus or minus 10%. If the reading is correct, the problem will be at the control board and it will need to be replaced, [9759558] If the reading does not fall into this range, replace the convection heater element.
