I just moved to the new apartment and here we got an old dirty whirpool gas stove with nasty fat stains. I checked it and few burners would stop burn if I stopped to push the button. All the sparks worked alright. I assumed the problem was in thermocouples that were dirty.

gas stove after disassembly, everything works if you use it like this without the cover

I disassembled the cover to clean the thermocouples as much as I could using the means I have. Before putting the cover back I double checked and every burner worked fine, without issues. But as soon as I put the metal cover back the spark stopped to appear at any of the burners.

gas stove after I put the cover. Now it's not working

I repeated the process and took the cover back again and… magic! every burner works perfectly, sparks are there, thermocouples seem to work as well. If I just roughly cover it with the cover (see the photo underneath) it still works, the sparks are there.

gas stove with the cover roughly covering it

I assume there is a simple solution but I am really bad at electronics and stuff. Need your help, can’t solve this mystery. Thank you

    The cover is probably shorting wire/s when it down right. Would go over every wire carefully(maybe with a magetiving glass) to check for breaks in the insulation.

    Put the actual burner 'tops' back on. That's where the spark is supposed to go to. Without them, it's going to go to somewhere 'wrong'.

    @Tetsujin I put them on when I test the spark and everything. The problem remains - when the cover is not on it works. When it's on - it doesn't.

    @crip659 I have identified the problem. Well, I admit it was stupid one. So basically when I closed the lid I did it not tight enough to the ground (there were 2 metal hooks on the right side that you had to put the lid base underneath). Basically the lid had to be pressed as tight to the ground as possible. Otherwise, (and that is what actually happened to me) the 4 black buttons won't go the whole distance down to invoke the spark. When I pushed them I thought that I pushed them all the way down but in reality they were blocked by the lid itself.

    Nice that a solution was found. Sometimes it is an easy solution in that one surface needs to be placed in the right way. Had a locking connection once that was hard to find because it was not tight enough(about a 1/16 loose) but still locked.

  • This also serves as a reminder to use all your senses - presumably when it sparks you can hear it click, and when it doesn't, you can't. A spark going to the cover instead of the burner would still click, so no sound means no spark anywhere
