I have an older GE wall oven. Got fault code 2 this morning after overheating it using the broiler with the door closed. Online research led me to think this might be the oven temp sensor. I found to GE oven sensors locally that are not the exact same part; one longer, and one shorter. The salesman told me he thought they were all interchangeable. I installed the shorter one, and now got an F4 code (shorted temp sensor). Then I installed the longer one, and now got the more ominous F8 code (faulty ERC). My question is, are these parts truly interchangeable and the oven's clock/circuitry is messed up, or do you think there is a chance that the right part would completely fix the problem? THANKS!

GE TFX22RJB (GV222883) I can't believe I'm having trouble the thing is only 22 years old! The FREEZER is holding at about 25 - 30 degrees and the other section is staying around 45 degrees? Before running out and buying a new one I'd like to try and repair this one. With your help a couple years back I completely rebuilt the door dispensing unit. I have tools and am fairly competent at repair. I just do not know how to troubleshoot a REFRIGERATION unit? The ONLY things I have done so far is turn the unit off for 2 hours, turn it back on again on the highest settings and waited 24 hours to check the temperature in both sides. The numbers above are the numbers before and after the test. The refrigerated side of the unit has a damaged seal on the bottom. We thought that might be the problem but I made sure it wasn't leaking before I did the 'Test'? This seal is just over a $100.00 to replace, which we will do if the other problem can be found and corrected for a reasonably small cost? Otherwise we'll have to buy a new unit! Could anyone direct me from here? Also is there any one or two 'Probable' causes for this type problem? Thanks in advance for any and ALL help!!!
