Have a Jenn-Air range SVE47600. Control module keeps failing.

Resolved Question:

Have a Jenn-Air range SVE47600. Control module keeps failing. First one lasted 11 years. Original board was by Robertshaw, Replacement boards are by Invensys but are direct replacement. Robertshaw were thru hole components . new board is SMT but looks like the IC main chip keeps failing getting F-7 failure code. Have replaced board 4 times in 7 months with same failure symtoms. Board fails without oven operating. Will work for a while then go into the F-7 failure mode. IC chip is similar to original and has Robertshaw name on it but is by another chip mfg. which I can't identify. I can't seem to get a schematic. AppliancePartspro.com is replacement parts vendor who doesn't have any info to help.

Looking for experience and assistance. Know anything?

F7 has nothing to do with the control board. The reason you continue to get the error is because you're replacing the wrong part. F7 means that your touchpad is shorting out, or it thinks a button was pressed and held for more than 32 seconds. Either way, you need to replace your touchpad to fix your issues. By unplugging the unit and moving the ribbon connection around from the touchpad to the display board when you change the display board out, you're probably getting the touchpad to work again, either way you need to replace the touchpad.

Where can I find the failure codes for this? The only manual I can find does not list them.
Is there a service manual available with schematics?

That's very interesting .. I've been trying for a year to find what the failure codes meant.
I took the panel apart as far as I could without destroying it but don't see a way to get to the key pad. It looks like a vynly cover is pasted on over it. Is there a way to get to it or do you know if the control panel is available?
Expert:  Tyler Z. replied 4 years ago.
you just need to replace the entire front face panel on the control panel and unfortunately I have no idea of the part is still available or not, you'll need to call a parts store to figure that out.
