I keep getting a 4d21 on screen and feature not available comes up . Oven wont come on ? What does 4d21 mean ?
The error code 4d21 is a no reverse airflow rotation error. Would have to do with the fan on the unit not working properly or not at all. Would want to check the voltage to the fan to make sure that it is good. If no voltage then replace the control board and if there is voltage replace the fan.
F1-7 on screen.
Answer Hello David,
Ensure ribbon cable is securely connected, inspect ribbon cable and connector (shorts, breakage, corrosion, etc.). If OK, replace control 74006363.
Our Jenn-Air JDS9860BDB range is 5 years, 8 months old. The gas top works fine. The clock/day of week works fine. Our keypad is not responsive unless I kill the power, then power up. Everything works for about 1 minute, then goes to just the clock/day display. I'm comfortable with electronics. Getting behind the panel was easy, nothing looked fried, visually checked/cleaned all connectors. Definitions of parts are an issue. I saw the PC board, is that the "ERC" electronic range control? There are also the LCD screen and the well hidden keypad. Which part(s) should I order? Thank you great helpers in the cloud! - JH
Answer John, You're on target, mostly. The PC board and display are all inclusive with the ERC(electronic range control) 8507P232-60. The keypad, is also inclued in the control panel W10206070, based on your post, thats the part you're going to need. If you have a multi meter, you can check each keypad for the proper circuitry when pressed, but that test could produce the desired readings and still have a malfunction.
