Jim for Model Number KGRA806PSS00 Gas heating in the oven is having a problem, but broiler (upper part) works fine. When oven is turned on, only the heating coil/rod turns on. No heat comes from underneath (gas heating). No sparking sound either. Is the oven burner (AP3879440) need to be replaced or the oven Igniter Assembly (AP3135265)? Also, items #9 and #10 in the diagram seem to be the same thing, are they? thanks.
Answer Jim, It's probably neither of the parts you referred to. It's more likely a faulty DSI spark module WPW10331686 or gas valve WPW10331686, You should check the solenoid resistances on the gas valve (215 ohms resistance from the center terminal to each outside terminal) and the VDC (8 to18 VDC) on the red and orange wires on the valve, with the oven in a bake mode. Heres some meter usage information if you need it,[http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html]. The burner tubes (items no.#9 and #10)are configured differently so they are not interchangeable. Good Luck and Thanks Read More... Answered by AppliancePartsPros.com | Tuesday, February 21, 2012
