Westinghouse Stove

[relkin67]

This has got to be the oddest case of bad caps. When I got home last night, my stove was half-heartedly bleeting out the alarm that normally goes off after the rudimentary countdown timer goes off. This despite the switch being set to time not alarm.

Thinking that it might be a bad timing cap, I took apart the control board and replaced the two electrolytic caps (470/16 & 1/50) with spares I had lying around. When I put the board back in, the alarm continued for a few seconds and then tapered off. OEM caps were "Marcon" brand dated 1993.

Can't say how great it is for the alarm NOT to be going off continuously. Would never have thought of this repair if I hadn't been a member here. Thanks everyone.

Re: Westinghouse Stove

Is the repair still a success? If not you might also have a problem with the crystal/ceramic resonator. I had such an issue with my range hood that caused intermittent erratic operation: https://www.badcaps.net/forum/showthread.php?t=8654

Agreed a bad clock reference can cause all kinds of wonky things to happen with the micro controller.

Yeah, the noise came back in a weird but utterly consistent cycle with the new caps (building to a crescendo then quieting and repeating the cycle - clock would flicker too [the 7 bars would all light]). I don't cook much so I left it unplugged for a day.

WHen I replugged it in, all was good and the noise is gone. Been that way for 36 hours now.

I'm happy as-is but if it comes back I will investigate the thread you posted. Thanks for that.
