GE Oven Problem

6 posts in this topic

Greetings Goo Roo's and thanks in advance for any help. 

GE Model number (from the tag, read with a flashlight) is a JKP45W0A2WW.  In a nutshell the bottom unit (double oven top & bottom) won't heat up.  Grab a beer this is a long story....

Some history.  About 6-mo ago the top oven stopped baking while the bottom unit worked ok.  Armed with a little knowledge and the internet, I order and replaced the thermostat as well as the bake element thinking I'd kill all birds with few stones.  The top oven returned to operation, but would not heat as fast as the bottom unit.  Wife complained...I learned to ignore it.  Top oven eventually gets to temperature.  Most interesting is that I had time to play with the "bad" parts.  The bake element had no outward problems and measured 21-ohms resistance.  The thermostat was around 1k-ohm at room temp.  Both sound good compared to stuff I've since read.  This (top) oven with "new and improved parts" still operates.

This weekend, the bottom (ole faithful) oven stopped working.  No broil, no bake.  I gingerly pulled the bake element and got 20-ohms end-to-end with no shorts.  Also pulled the thermostat element and verified operation...1019 ohms at room temp and the resistance increases when heat applied.  Also I re-installed the thermostat, turned the oven to BAKE and then held a flame under the thermostat.  Temperature reading on the digital display changed from 100 deg-F and increased up to 400 deg-F as expected.  Looks like the thermostat feedback to the controller display is working.  Still no joy on oven operations.

When I enable any of the oven modes, I can hear the control relays clicking, but have not verified any power is being switched.  I pulled the control panel away from the oven (with the breakers OFF) and can see that everything looks nice and tidy, but have not probed the control board. 

Is it worth trying to debug this control board?  Is this the next likely culprit?  Do these things break?

Thanks !

Yes, the control does go bad, however might want to check the limit switch ref. # 157 to see if it is good, does not say if it goes to the top or bottom oven or both tho...

Yeah, Yeah, my bad...first time out of the chute I realize that I'm in the wrong category to post.  Tried to go back and delete but couldn't.  Thanks for the suggestion on the limit switch.

Wiz.
