Double Oven Triping Breaker.

erik123

Hi, When I remodeled a friends kitchen recently he gave me the GE double wall oven. It was only used once and looked in perfect condition. I installed it in my own house yesterday. I pulled new 10/3 wire and put in the required 30amp breaker. The bottom oven is operated by a dial and it works fine but when I set the temp for the top oven and push start it makes a nasty buzz-clunk and trips the breaker. I'm confused, Could it be a wiring issue or an issue with the stove. I'm leaning towards the stove being the culprit. Any ideas from the ever helpful contractor talk community would be great fully appreciated. thanks Erik

It's pretty hard to screw up a double oven install, so I'd guess you did your install correctly. If the oven is tripping the breaker, the breaker is doing its job. I'd say it's more likely that something got jiggled loose in transit between your buddy's house and yours. You need to call the appliance repair guy.

Thats what I was afraid of. If the bottom oven works fine and the top trips the breaker then it must be something internally with the oven. I am not looking forward to finding out how much the appliance repair guy is going to cost.I would have never replaced our old single oven if I new this one was not going to work. There is no turning back now. It is installed in a brick wall in our kitchen! Any ideas of what the problem could be? Heating element??

Not that this will affect your problem but,,,have you checked the tag to see what this oven draws? 30 amps for a double oven is pretty low unless you have the high efficiency model

I don't know, brother. Most every one I've ever installed is 30 amp.

Not saying ALL doubles are 40A, just saying I think we need some data off the plate as their is a difference in opinion.

I would say most double oven I have seen are 40 amp, most cooktops are 30 amps and most ranges are 50, Now thats just from my experience!

Most D.O.s we install are 40A or 50A. Some of the single ovens with microwaves are 30A. I had the same thing with a 360A welder I got for free. It tripped the 2 pole breaker in the garage, and the sub-feed breaker in the house. I ended up scrapping it. It would have been great if it worked.

Just curious what you fed a 360amp welder with in your house; 500's?

Almost all double ovens I see are between 30 and 40 amps. Most are 35s.

If this is tripping with the top oven ONLY, I would say you have an internal fault.

Check the back panel of the oven. IF it is smashed in even a little bit, the back panel may short out the element terminals. Maybe the circuit supply junction box is located right behind it?

Last year, we did a service for a modular home. Once we got the power on, everything checked out. The people moved in, and the first time they tried to heat the oven, --- POW!! The breaker tripped out.

They called the appliance manufacturer for warranty repair. The repair guy came out and declared it was improper installation and damage to the oven, hence the warranty was void. Seems that the junction box for the circuit connection was located right behind the oven where there was not sufficient clearance, and when they installed the oven, the crew just shoved it in, bending the back panel in when it impacted the 1900 box.

Of course, this also shorted out the element terminals, something that could not be discovered until the oven was actually switched on.

The remedy was for the modular home manufacturer to order a new oven, and have us install it. Part of the installation was the relocation of the 1900 junction box so the same thing would not occur again.

When I did the install, I asked them what to do with the old oven. They told me to throw it out ...

I took it home to my shop. Straightened out the rear panel, and ordered a new control circuit board (which was fried by the repeated attempts to reset the breaker with shorted out elements). It took about 2 months to get the right parts in and installed properly, but I did manage to fix it.

Now I have what is essentially a brand new oven in my kitchen for a little over $150 worth of parts.

Out here single oven = 30 amp ckt and double oven = 40/50

???

The manufac.s sell the same units all over these United States.

You need to use some some deductive reasoning here.


When we are roughing in a kitchen "out here" we rarely have the appliance or a cut sheet on site. For a single oven (rare) we run a 10/3 NM 30 amp circuit. For a double oven of any type we run a 8/3 NM 40 amp circuit.

Celtic

I don't.


The "lurkers" may think "out here" is some other planet.

You might want to be a bit clearer for their benefit.

360A DC I would never fabricate any air craft carriers so I would only need upto 100A DC or so. It was an antique so I got rid of the stupid thing. It only required 60A 240V.

It would appear we have found the high efficiency model...somewhere in Amish land

I would rather know what's going in and not guess and be wrong with the price of wire now adays.
