Help or guidance Please for GE p7 wall oven

[racinboo10]

Hi! I have been trying to fix and locate correct parts for my GE p7 wall mount oven. It no longer heats up, I was going to replace the element and the temp sensor. When I pulled the element out it has something on the element that I don’t see on any replacement elements that I found. Can anyone please point me in the right direction? Looking for element and temp sensor. Any help would be greatly appreciated! Thank you
Michael

Is the element bad? They usually have a burned spot in them when they are bad.

 I would look for a broken wire first. Don't start throwing parts at it.

Early GE P-7 SC Oven

The sensor on the bake element is the lock thermostat and over heat protector for the oven, if the element needs replacing you remove this thermostat and mount it on the new element.

 

These early P-7 ovens were very good but complicated , if it does not heat at all it could be a bad sensor, bad selector switch, bad responder or circuit board depending on which system your oven has, bad heat relay, bad sensor on the bake element, bad transformer, bad lock switch and of course a bad wiring connection.

Thank you guys, I will pull the oven out and test some things with the ohm meter and go from there. I appreciate the help. I will try to test things this weekend. Thank you for the guidance!

Circuit boards?

Old P7s had circuit boards?

Early GE P-7 SC Oven

Hi Sarah, The 2nd generation GE P-7 ovens around all had a little control board in the temperature control circuit, they were fairly reliable.

 

The 3rd generation P-7 ovens went to a dual range mechanical thermostat that had sodium potassium filled capillary bulb, this system was used from the mid 70s till they went all electronic controlled ovens for the p-7 ovens around the mid to later 80s.

 

This 3rd ten system was the most reliable of the three major control systems.

Hey John L, interesting info.

 

Perhaps you can shed some light on the P*7 wall oven here.

 

I bought this 1941 house in 1997. Looks like the kitchen was remodeled in the 70's or 80's. The P*7 wall oven is original, although I replaced the Harvest Gold oven door with a stainless steel version I got about 15 years ago off Craigslist.

 

I am wondering what generation this oven is.

 

It's Model JK190R3HT.

 

S/N RT644340G

 

4.6 Amp at 220 V.

 

It works perfectly although the temp probe and rotisserie accessories are missing.

Hi Rich, I can not get that model # to come up, GE was sometimes funny on older model #s, if you post a picture of the controls I can better answer your question and date the oven.

 

There are no JK models usually would be a JKP if a P-7 oven in that time period, a JKP19 has electronic touch controls, is that yours, maybe post a picture of the model tag, they also never made a P-7 oven that had 220 volts on the model tag.

GE...

Was sometimes funny on the older model #s.

Yep. Our house had an older GE double wall oven when we moved in, and one of the doors had a cracked window. I called GE about it. When the rep couldn't find the model number in the database, he told me to buy a new oven. I bought a donor oven from the Habitat ReStore and replaced it myself.

Since then, I've purchased many vintage and used GE products. I'm sure my getting mad and taking my business elsewhere has really hurt their business. Not. But it makes me feel better.

John,

 

OK, here are the photos.

 

It is definitely a "JK" model, with no "P".  You can also see that it's a P*7 model.

 

I got the voltage wrong; it's a 120/240 model (which is how this house is wired).

 

Let me know.

GE P-7 Wall Oven

Hi Rich, Your oven has the simpler 3rd gen oven control system with the mechanical thermostat, it should be mid 70s to early eighties, the only thing electronic was the temperature control for the meat thermometer. 

 

I probably have all the stuff for the rotisserie and a meat probe for this oven if you need either.

 

These were very good ovens, the next generation GE wall ovens went to an electronic oven control system and used a lot of Roper parts as GE had acquired Ropers manufacturing fascicles, the ovens were never as sturdy or well built after that.

 

Julia Child used a double oven version of your oven when they filmed her book, The Way To Cook which I consider her best work.

Wow!

That’s a gorgeous oven.

[sudsmaster]

Thanks, John and Sarah.

 

Yes, this oven, despite being about 40 years old, still works great. The only thing I've done with it is a slight adjustment to the temperature dial (easy).

 

I confess I don't use it all that much. Since I've gone low carb I don't bake bread much any more. And for roasting meat I use a rotisserie propane grill set outside in a covered patio area. But you never know. For frozen pizza I use a largish french-door bench-top Oster convection oven, which works fairly well if a bit unevenly. I just rotate the pizza half-way through to get more even browning. Also use the Oster for stuff like frozen pre-cooked chicken wings and shrimp.

 

Mostly in the past few years I've used the GE wall oven for cleaning cycle decontamination of burner grates and drip trays for the Frigidaire "Gas On Glass" 36" cooktop.

 

However recently I bought a big frozen beef lasagna at Costco, and it will probably be prepared in the P*7 once the weather here cools down. I could use the Frigidaire Compact 30 out on the enclosed patio, I suppose, but I've never calibrated that one.

My cousin's had the double oven version in Harvest Gold when they lived in Memphis in the mid to late 70's.

Combo/JohnL,

 

Yes I'm interested in the temp probe and rotisserie stuff.

Maybe we can explore Venus with self clean ovens?

Was the first generation P*7 totally mechanical?  In the video, the engineers refer to an "electric thermostat" rather than a "hydraulic" one.  Now NASA having inventors submit ideas for a probe that can explore Venus that has to be heat resistant and some designers are going with an all-mechanical design because electronics cannot survive in the heat.  

 

Also, with some modern self clean ovens, won't using the SC cycle fry the electronics?

John Lefever,

 

Did you get my email?

Hi Rich, I emailed you this morning, but a warning to all I take a long time to respond to Emails if at all, message me here on AW you will get a faster response.

John,

 

Got the email.

 

I will email you back.

>with some modern self clean ovens, won't using the SC cycle fry the electronics?

If they are poorly designed maybe. Hopefully they don't place the circuit board inside the oven cavity I do know of a wall oven a friend had that failed the control board during a self-clean cycle. Hardly a fault of the electronics, that is bad design.

Electronics sure get a bad rap around moisture and heat, both of which they are fairly unaffected by as long as its not extreme. I have one poorly designed RF amplifier I kept going for years. About once a year the output transistors would get hot enough to physically unsolder themselves from the PC board!!! Even though the transistors leads exceeded 360 deg F they never failed.

Why so complicated? What was the point? Why not just a simple variable T state? Heck in my world ovens don't even have a T stat lol.

 

[sudsmaster]

John,

 

My error. The model tag says 240, not 220.

 

By my latest count, I have about 20 washer/dryers/dishwashers in my collection, not including the stuff I use regularly in the main house, and not including ranges of one sort or the other.

 

Couldn't find the harvest gold door off the original wall oven. Doesn't mean it's not hiding somewhere in the junk heap. Unlikely that I junked it, but of course anything is possible. Probably I stuck it on the one I got the stainless door from, just a matter of finding it. I just got a bit overwhelmed counting the 20 that I did just now. Next time I'll bring a pad to record all the particulars.

Top oven baking element won’t heat.

GE P7
Automatic Oven Cleaning
Model JK2905WH
Serial # DY94672

The element as shown does not match any of the elements I see for on-line parts replacement. That part of the element that goes back behind the rear of the oven wall is not familiar.

What might be wrong ?
Who has this ?
What do I need to buy to fix this ?
Part #
Don’t want to buy a new oven just yet.

This is my girlfriend’s oven.
My girlfriend doesn’t cook much…she only has a kitchen……because it came with the house !! LOL

 

[sudsmaster]

 

 

Hmm.

 

This house I purchased around 25 years ago has pretty much the same P7 wall oven. It's always worked fine, not that I use it much. Aside from that, I cannot figure what's wrong with the one you shared, other than it looks like someone tried to replace the heating element and then quit.
