WFG374LVB2 whirlpool direct spark oven lighting problem

6 posts in this topic

Appliantologists,

I read the FAQ's  and the direct spark instructions in Whirlpool's sevice pointers are from 2002. This is a 2011 range.  That does not discount the early directions.  I checked the grounding on my first trip.  I'd forgotten the igniter alignment. The oven worked the whole time I was there. I was wondering if there was a new problem causing inconsistent heating and possibly new repair strategies.

Sounds like a possible weak spark module from the symptoms...

What are the symptoms, intermittent sparking or heating, and is both bake and broil affected?  I've had to replace more than a few safety valve/regulators for heating issues.

There are three wire terminals on the oven safety valve; the bake coil and the broil coil both need to be about 200 ohms each to the third terminal(common).

True, but if one of these were open, the oven would not work at all, it wouldn't be an intermittent problem. You can also measure these from the DSI board, which is a lot easier to get to (Blue, Orange, and Red).

What did you end up doing with this unit? I am having the same problem. Oven works most of the time but intermittently does not. Only malfunctions on bake.

Temp sensor checks out ok with meter

Gas valve checks out good with meter

Ground is good

Igniter clicks every time, just does not light.

The unit does not have a tech sheet so I am going with numbers that I have found on other post for checking sensor and valve.

Problem seems to be worse on lower temps.

Thanks for any help
