Well…my saga continues…Went to cook a take home pizza…(Papa Murphy’s… Yum!).Set oven temp to 400 - preheat cycle started…Oven came up to temp, popped the pie in the oven, and about 10 minutes in the oven beeps and displays an error code E2 F3. Used you site to diagnose - bad oven temp sensor… Well shame on me for not checking resistance and confirming that the sensor was bad… Ordered a new temp sensor from AppliancePartsPros - great service by the way. Installed new sensor in oven compartment - and the oven threw the same code. Pulled the lower (broiler?) sensor and checked resisitance - right at 1.1k Ohm. Checked the old temp sensor and it too is at 1.1k Ohm. So now what? ERC? Do NOT want to throw $300 bucks unless I am sure this is the culprit. Help!
Denman,
Double checked both the oven and broiler temp sensors at their connections: both were 1.102 k ohm.
Traced the leads and checked them at the control board - weird thing is the resistance went down: oven was 0.928 k ohm and the broiler was 0.950.
Pins were not discolored and all connections were sturdy - nothing looked loose, burnt, off color…etc.
All components around the connections appeared solid, and no cold solder that I could see.
Oven was unplugged for 12 + hours - so I think I have the reset covered…
Anything else before taking the plunge on a new circuit board???
Help!
I cannot think of anything.
Perhaps someone else will jump in with another possibility.
unfortunantly the sensor plugs into the control board. these codes are not always accurate. as a tech you have to basically take an educated guess, because the meter will only take you so far. the clock control board, is the last thing it could be at this time. tom
I have seen this couple times and called our tech assist line and twice was told to remove the plug for the oven temp sensor and hardwire it. Apparently the plug can be the issue. I personally was not called back out on those ovens but I have no way of knowing if someone else got the call so I cannot promise it will fix it but it is a lot cheaper than a new board.
Great site guys… Nice to see so many people jump in for a go… I will hard wire the oven temp sensor and see what that nets me.
Again, I really appreciate the responses.
Was thinking about the next step, and after trying the hard wire fix…will probably call a service tech and see what this would cost me. At least if they replace the board there should be some warranty period, and hopefully some other type of resolution / credit if it turns out to NOT be the ERC. I am assuming that once I purchased the ERC from Appliance Parts Pros that there would be no option of return? (Typical for electronics).

If you do try the hard wire make sure to leave some wire on the sensor plug so you can splice it back on in case the hard wire does not fix the problem.
Otherwise you will have to buy a board and a new sensor.
Will do Denman. And I will also call Sears service and see what I can do. Also was thinking about a home warranty - and making a claim afterwards. Anyway, anxious to have my stove back up and running…
