On my RDDS30VQB everything starts out fine and all burners light with a spark. Then, for example, after 2 burners are lit for a while I try to light the third (it could be any burner, not a specific one). The third gets no spark, but I can light it with a match. The same issue happens if I have 3 burners lit for a while and try the 4th. Or have one burner lit for a while and try the 2nd.
After searching many forums, I concluded it must be the 4 point gas re-igniter. So yesterday I replaced the original RI 324 with a new one RI 302 I bought from appliancepros.com.
Everything seemed to work fine, meaning all burners started out lighting properly with the spark as before I did any part replacement. I had not yet tried all the combinations where the burners fail to light after at least one is on for a while. Well this morning, no burners will ignite - there is no spark from any burner. Yet all burners can be lit with a match. So I removed the new part RI 302 and put back the old one RI 324 hoping to get back to where I started. Well no change - no igniter spark on any burner yet I can light all with a match. This is with the old part put back. What is going on - help!!!
The serial number is 20100003
Finally fixed. It turned out to need both a spark module and gas simmer controller. Wires and electrodes were fine.
