GE Microwave Relay Needed

My mother bought what has to be the world's cheapest GE Microwave...totally against every recommendation I offered. Amazingly, it did manage to last just beyond the warranty period.

This is the second time it has broken. On the first time around, the relay that controls the fan, light and turntable motor unsoldered itself from the control board. I soldered it back on, and the microwave worked again.

It died again few weeks ago, and I just got to looking at it. The same relay is to blame. It has badly burned contacts, and no more heavily than it is loaded, I suspect it was a dud from the start.

The relay is am Omron G5G-1A (rated 16A/120 volts) with a 12 volt coil. I don't have anything in my junk box that would work as a replacement, and I can't find it being offered for sale anywhere.

A call to Omron was unhelpful to put it kindly. I was told that the part was custom made until I pointed the operator to the data sheet on their own web site. Then I was told that they couldn't just provide one, a minimum order was fifty and there would be a 12-14 week wait.

GE parts will sell the control board for $61...as much as the oven cost new. They didn't think I could order just a relay, although the person I spoke with did claim to look into it.

Anyone here have such a thing in their junkbox or know where to get one?

My guess is that unless you can dress the contacts, you're stuck finding something similar and adapting it to fit. With 12 volts on the coil, that points to a vast inventory of automotive products to choose from.

Where I live there are a lot of junked microwaves available, as well as working ones at Good Will and Salvation Army. Any of those might have a spare. Also, where do you live, it might make it possible to get one to you?.

Thanks. I've gone ahead and put in a request, guess I'll see what they say.

Here in the Phoenix area there is a non-profit outfit called Stardust, which mainly deals in used items from remodels - cabinets, fixtures, stoves, etc., and uses the proceeds to help people with housing issues. The usually have quite a selection of microwaves. Maybe you have something similar where you live, where you could pick up a donor microwave for cheap.

Hi!

It was difficult to open the relay without destroying its internals. I mangled the casing pretty badly while trying to ease it up and off. It's still functional. The contacts are so badly burned that I haven't been able to save them so far.

I hadn't thought of that...that is a good idea. I'll have to see what is on the market if some of the other leads don't turn anything up.

I'd let this oven go and send it toward the parts bin and recyclers, but I hate to do that.

What is the contact architecture? I've seen automotive relays up to maybe 8PDT or more. If you can find a similar, different voltage, relay, perhaps you can swap pieces from it....

In Nashville, the Habitat for Humanity folks have a couple of stores dedicated to 'home' stuff. One deals in appliances and architectural pieces, while the other stocks donated housewares; although there's a bit of overlap between them. Also quite a bit of overstock hardware items, and mis-mixed or leftover paint.

William,

Have you checked Mouser Electronics? Their catalog has 17 pages of PCB-mount power relays. They carry Omron relays, but not the G5G series. If this is the type of relay with the contact terminals sticking out the top, they have Fujitsu, Panasonic, and OEG relays in that configuration. The pinouts may be different than your Omron. In that case, you'd have to drill new mounting holes in the PCB and run jumpers to the coil pins.
