Jenn Air Microwave Troubleshooting

While Jenn-Air microwaves are well-made, they are not immune to problems. They are prone to maintenance issues just like any other device. That includes not turning on, not heating properly, door jams, buttons not working, error codes, and the turntable getting stuck, among other things. 

Most of these problems can be prevented with good maintenance, but that’s not a guarantee that you’ll never experience problems. If you do experience such issues, there may be something you can do before having to contact a professional. Here, we’ll address many common issues with Jenn-Air microwaves and how you can troubleshoot them.

Jenn-Air Microwave Not Turning On

There are several reasons your Jenn-Air microwave may not turn on:

• It is not receiving power
• The door is not closed all the way
• Control Lock is enabled
• A component is damaged

Of course, trying to find out what the exact problem is can be difficult. This is where troubleshooting comes into play. The first thing you’ll want to do is check the power. To do this, ensure that the microwave is plugged into a working outlet. If the outlet is operational and the microwave is plugged in, check your circuit board for a flipped breaker switch.

If the outlet is operational and there are no breaker switches out of place, it is possible that the microwave cord itself may be compromised. The only way to fix that is to replace it, but be sure to continue troubleshooting first.

For instance, make sure the microwave door is closed all the way, and that there are no obstructions. The microwave will not work if the door is not fully closed. There may also be an error code on your Jenn-Air microwave: “L” or “Loc” means control lock is enabled, and you will need to disable it. If you have a different error code, look up its meaning.

If none of these are solving your problem, the microwave may have a malfunctioning component. At that point, you will need to call a professional to assess it.

Jenn-Air Microwave Not Heating Properly

If the microwave seems to be functioning properly but it never actually heats the food placed inside of it, it is not heating properly. Unfortunately, if you are experiencing this problem it is almost certainly related to a component failure, such as the diode, door switch, or high-voltage capacitor.

It’s difficult, if not impossible, for you to troubleshoot which of these parts is the actual issue with your food not heating properly. Needless to say, a part will likely need to be replaced. If your food is not heating even though the microwave appears to be working otherwise, you will probably need to contact a professional. 

Jenn-Air Microwave Control Panel Not Working

First off, press all of the buttons on the touchpad to determine if the entire control panel is inoperable, or if there are only certain buttons that are not functioning properly. If some buttons work but others don’t, you’ll have to replace the entire touchpad, as there is no way to repair individual buttons.

Other than that, ensure that the microwave has power. Make sure it is plugged into a working outlet and that no breaker switches have been flipped. If the touchpad displays an error code, look up that error code and take the necessary steps to rectify it. If none of these things work, you will need to call a professional.

Jenn-Air Microwave Door Won’t Open

If the door to your microwave will not open, it is most likely due to the door latch hook being broken. This is something that can happen over time due to general wear and tear. This is one of, if not the only reason your microwave door will not open. To fix it, you will just need to replace the door latch.

This can be a little bit of a hassle, so you may want to call a professional. However, it is not impossible to do this procedure yourself. 

Jenn-Air Microwave Making Strange Noises

It’s normal for your microwave to hum during operation, but if you start hearing loud and concerning noises during its use, the problem is most likely related to a circuit malfunction, either in the microwave or your transformer. Be sure to check your home circuit board and ensure that all fuses are operational and accounted for.

If they are, then your microwave probably has a component damaged. Electrical components are very sensitive and difficult to repair. You should not attempt to conduct electrical repairs on your own, as there is a great chance of harming yourself or causing further damage. If your microwave makes strange noises during operation, contact a professional.

Jenn-Air Turntable Not Turning

If the turntable is not turning, follow the steps below to troubleshoot the problem:

• Ensure that all packaging and protective material have been removed from the turntable
• Make sure the turntable is correctly installed
• Make sure turntable mode is on, if applicable for your model

The owner’s manual will tell you how to accomplish all of these things. If none of the solve your problem, there’s likely a component malfunction, and you will need to call a professional to replace it.

There are a number of error codes and messages that can be displayed by your Jenn-Air microwave if something is wrong. But it can be difficult to know what they mean or what you are supposed to do about them. Refer to the bullets below to learn everything you need to know.

• F0 – Function Key Stuck: Replace the Touchpad
• F1 – Defective Touchpad/Clock: Replace Touchpad or Clock
• F2 – Temperature Too Hot: Replace sensor or relay board
• F3/F4 – Temperature Sensor Shorted Out: Replace It
• F5 – Hardware and Watchdog Circuits Disagree: Replace Clock

Conclusion

Proper maintenance will help you avoid many of the problems mentioned in this article, as well as being careful with your microwave. Clean it regularly and don’t slam it unnecessarily. If you encounter problems, go through typical troubleshooting steps before calling a professional, so you can save time and money.

That means testing the power supply, reading up on any error codes, and being aware of what problems are likely the result of a component malfunction. Many problems can be fixed by you, but some issues may require a professional. If you determine that a problem is too complex to deal with yourself, do not hesitate to enlist professional help.
