Should oven relay be replaced after welding?
« on: September 21, 2017, 02:02:25 PM »

Hi Everyone,

Recently our oven started getting really hot, I tracked the problem down to a welded oven relay, with the application of some preclusive maintenance I got the relay to open again. Is it likely that it will keep working normally again or should it be replaced?

I was debating replacing the two relays on the oven relay board (much cheaper then a new board) but if it's likely that they will just keep working I'd rather save the money.

In my experience, it will most likely stick again. The "points" or contacts become pitted and arc when they attempt to connect. This is what causes them to weld together. If you can find a vendor number on the relay, you might be able to find a replacement at http://www.mouser.com

Hi Scrapiron, thank you for the reply, I was wondering if the contacts had degraded, I'll just go ahead and replace them. There's a local electric supply store that can get them in for me, all these online suppliers have crazy shipping fee's from what I've seen.

Mouser will ship First Class Mail for about $3. It doesn't show up as an option, you request it in the comments at checkout.
