      Returning guest presenter Aaron Wilson is back for another exciting discussion. This time, we'll be talking about...
      The Science of CYA: How to Keep the Customer Safe, Document Your Work, and Not Get Sued
      We take on a lot of liability as appliance repair techs, and that can get us into sticky situations whether we've done anything wrong or not. Aaron will be teaching us all about how to navigate this side of the trade.
      We'll start by going over a tragic, real-world case study where a sloppy installation had lethal results, analyzing exactly how the installer's negligence caused this. From there, our scope will expand to what kind of safety precautions we should implement in our own work, both for the customer's sake and for our own.
      But even if you do everything perfectly, there's still the famous "technician witch hunt." Well, we'll also talk about how to deal with that by thoroughly documenting your work and putting yourself beyond legal reproach.
      A little about our guest, Aaron Wilson:
      Aaron has been in the appliance repair trade for about 15 years, starting out by doing installations before moving on to bigger and better things. He worked for C&W Services as a Sub-Zero authorized servicer for a time and thereafter joined Mr. Appliance of Highland Park in the Dallas area, where he worked for years as the lead technician and field service manager. These days, he's making sure that all the appliances of everyone's favorite fried chicken place are in tip-top shape as the Quality and Performance Consultant for the southwest branch of Chick-fil-A. In addition, he has taught many classes on refrigeration repair and advanced diagnostics, during which time he also developed training material for the soft skills side of things, which he is delighted to share with you. On top of all that he's a certified graduate of the Master Samurai Tech Academy, so he knows his stuff!

GE Single Wall Oven JT3000SF6SS overheating


Recommended Posts

The oven continues heating after reaching the target temperature set in the display board, ending with the error code F20 due to overheat. 

When this occurs, the oven does beep when it reaches the target temperature, as it should do it, but the heating element continues on, though the display is not updated with the higher temperatures. After some time, the oven displays the error F20 due to overheating. 

I took out the temperature sensor and found it in good shape visually. Also, using a multimeter confirmed a resistance of 1086 ohms at room temperature. 

I'm trying to determine my next course of action. Would the control board be the culprit, or something else?

Appreciate the advice.

Forgot to mention that the problem occurs randomly which makes troubleshooting more problematic. Most of the time the oven works well until the issue reoccurs after several uses.

Since you've verified that the sensor is where it should be, the only other component that dictates when the element goes on and off is the board. Sometimes, the relays in the board get stuck or fused together, and will cause the element to remain on. At this point, I would replace the board. Looks like the part number is: WB27X29607.

Thank you for the advice @Daniel.A. I'll proceed with the board replacement.

A follow up question, does the control overlay need to be replaced along with the board, or can the existing one be retained?

@Guaro DC The existing overlay should work. Looks like the board I listed has the buttons on the board itself, then a plastic overlay that depresses the buttons on the board. Then you have the user-facing overlay which sits on top of that.

Thank you @Daniel.A I just ordered the board you listed and will be working on replacing it next week. I will revert with the results!
