GE Oven doesn't reach temperature (120-150 Below setting)bAKE

[Earl Dryer]

The oven sensor is 1100 ohms all the wiring and connection are good, both elements turn on, Broiler on Hi heats the oven to 340-350,
Bake heats oven to 210 when set to 350 and 350 when set at 500.
Both element show 2-3 ohms diagrams with range show broiler  to be 16 ohms & bake to be 22 ohms. I think my problem is the control board but I cannot find any part breakdowns for this thing.  
 
Thanks,
Earl

Thank you AJ, that was the 1st place I looked, There are no illustrations and most of the parts are listed as unknown part, Have any suggestions of which part is the right one. Thanks


PS I was a tech 20 some odd years ago. Came out of retirement we
have no repair people in this area, so here I am. Technology is different basics are the same, sometimes I may need a little reinforcement from the newer PROs.

Call 1-877-477-7278 and tell them you need

The part you get will probably be after market made in mexico and will not come with new wiring instructions.Give them youe model and serial number and let them verify that I have the part number correct. This is the oven control board

[Earl Dryer]

Thank you, JW for your help, I 'll my sale rep at APP and get him to fix me up. I found a site that would rebuild these no longer in production boards but couldn't locate any after market stuff.
Thanks again
Earl

PS. Just got off phone with APP Ap2025110 is no longer available.

What does that tell you about GE products in particular? Makes you want to run right out and buy another electronic new fangled bunch of mess don't it?

[Earl Dryer]

You know, I think I'll spend my whole Goverment stimulus check that way
Thanks again
Earl

SearsPartsDirect shows they have the Control in stock $199

http://www.searspartsdirect.com/partsdirect/retrievePartAction!search.action?productGroup=N%2FA&partNumber=WB27K5055R

but check your oven sensor again:

1100 OHMS @ room temp
2650 @ clean temp (850F ?)

2 OHMS per DEGREE F =
1650 ohms @ 350F

1950 ohms @ 500F

It's the electronic control, for sure. The pre-heat function relies on a 60 Hz. clock timing to complete the initial preheat. When the EEPROM chip fails the clock can start to run on 50 Hz instead, causing it to prematurely reach the preset temperature on the display way before the oven has had time to catch up, heat-wise. The oven sensor does not have anything to do with this function.

[Earl Dryer]

Thank you all, I will check the sears site. Re-pair man can EEPROM chip be replaced to correct the problem?

[Repair-man]

I feel like DR. McCoy on Star Trek when someone asks me a question like that...

"Jim, I'm a doctor, not an electronics engineer!"   

I've never touched a single board to repair it for any reason in all of my 34 years of appliance repair. Some folks might be more comfortable with things like that, but that's not in my relam of expertise.     Yet.  Too many factors may have caused the chip failure, including power surge. This likely took out other components, like diodes which may be in the circuit to control power flow. Unless you are prepared to diagnose the whole board, replacing the chip alone is a gamble.

  Good anwser BONES. I'll call Sears tomorrow to see if that part is in stock for real. Computer says it is (same part # with a R suffix) recon the R is for rebuilt or remanufactured?
