Whirlpool WP74005890 Cooktop Spark Electrode OEM Part

The burner lit when I used a lighter so figured it was electrical. There were only 2 electrical components so I first tried replacing the block terminal. This did it, very simple and saved $250 on a whole new unit.

Excellent exploded view from AppliancePartsPros to help identify the likely parts. The Jenn-Air stovetop burner "module" can be unplugged, and once that was done some relatively simple disassembly of the burner module with a phillips head screwdriver was all that was needed to get access to the parts. The spark igniter needs some angling to get it into place, but once done it screws back down. Be careful with the gas supply lines, on this model they're simple rigid pipes, but they do have to be re-aligned or adjusted when reassembling the module. A suggestion might be, based on the age of the stove, to include some new screws for the spark igniter. They're small and it looks like over 10 years they've worn down a bit. I spent $75 with shipping to fix a part that would have been almost $300 to replace. Well worth the effort.

First thought the sparker at the burner was out so went to my local appliance parts store and purchased a new one for $32. This did not fix the problem. Traded the good sparker in the front with the bad one in the back and still no spark in the back but now the bad sparker is working in the front. Should have done this in the first place. Now I know it is the igniter terminal block. I then decided I can wait a week to get the part cheaper online. The original sparker from AppliancePartsPro.com was $13 compared to $32 at the local appliance parts shop. The terminal block was around $50 online so it probably would have been over $100 from the local shop. The other great thing is the Youtube instruction videos. Sorry brick and mortor, next time I will go direct to AppliancePartsPro.com. Oh, I also got the online part in 2 days without paying any extra shipping fees. Good job AppliancePartsPro.

Ordered 2 control valves for the left burners. Works I also needed a Teflon igniter control block that sits on the control valve. Got an igniterplug assembly instead.
