JennAir JJW2430DS Series | Single Wall Oven Error Codes


Picture of JennAir Single Wall Oven JJW2430DSI’ll bet you’re glad to be back for another rendition of the famous Neli DIY Appliance Repair Series! This time we’re looking at the JennAir JJW2430DS single wall oven error codes.

Ever since the early days of JennAir, they’ve been considered a high-end appliance. There is good reason for that because their reputation for designing unique features into their products still holds true to this day. One example is the JennAir range with downdraft. Several manufacturers tried to design their version, but nothing quite like JennAir made it very far.

That said, just know that you have a well-respected appliance on your hands, and I think I know the reason you’re reading this today. It’s broke! Well, there goes all my praise out the window! Seriously, like any other appliance, there comes a day when something goes wrong.

Some of the errors are easily fixed with a simple on and off with the circuit breaker. Others may require a calibration (touch control, for example). Still others leave you no choice but to replace parts. If you’re a DIYer, maybe this is right up your alley.

Error Codes

Below are instructions about how to enter the diagnostics mode. CAUTION: If you’re not sure of your ability to fully understand this or other techniques listed here, please stop and set up an appointment with us. We can walk you through everything.

As a note about diagnostics, remember you can also find the model and serial numbers. Trust me, this knowledge will come in handy someday, especially after the existing sticker wears away and you can’t read it.

Before entering Diagnostics:

  • Unplug oven or disconnect power before performing the following checks:
  • A potential cause of a control not functioning is corrosion on connections. Observe connections and check for continuity with an ohmmeter.
  • All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000Q per volt DC or greater.
  • Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough. Damaged harness must be entirely replaced. Do not rework a harness.
  • Resistance checks must be made with power cord unplugged from outlet and with wiring harness or connectors disconnected.
  • If the oven does not heat, there may be a problem with connections to the power supply. Check the connection to L2.

IMPORTANT: Do not replace the control if there is no evidence of any failure.

To Enter Diagnostics Mode:

Before proceeding with any corrective action, perform the following steps to enter the Diagnostics Mode:

  1. Enter Diagnostics Mode by pressing the same three keypads three times in a row.

Single Ovens: Press KITCHEN TIMER>TOOLS>SELF CLEAN (repeat two more times)

Double Ovens: Press UPPER OVEN>LOWER OVEN>LOWER LIGHT (repeat two more times)

NOTE: You do not need to wait for any audible or visual feedback from the control between keypad presses.

  1. If control does not enter Diagnostics, continue repeating the keypad sequence from Step 1. All the keypads will light up when the control enters Diagnostics.
  2. From the Diagnostic Menu, scroll to the desired selection using the touch screen:

Error Diagnostics: View and clear the failure history.

Component Activation: Manually activate each relay.

Sensors & Switches: View the traditional oven cavity temperatures and door/latch switch status.

System Information: View the model number, serial number, and software versions.

Exit Diagnostics

*Here’s a tip to troubleshoot a blank display. Most of the time a blank display is caused by a blown thermal fuse, located behind the control panel/user interface. It’s enclosed in a protective sleeve. Remove the sleeve and check for continuity of the fuse. Replace if the fuse reads open.

If the display still comes up blank after replacing the fuse, you might be looking at replacing the control panel. Remember to always cycle power and recheck before condemning the board. You can go into more extensive troubleshooting, but you will need to reference the Tech Sheet included with your oven.

It’s usually located in the control panel area and has all the information you need to properly troubleshoot. But for this type of troubleshooting, it’s best to have pinpoint (skinny) meter leads for checking voltage and continuity in tight places.
