Luckily, there are some simple steps you can take to troubleshoot and possibly fix the problem yourself. All you need is some time, patience, and a few basic tools. Let’s get started!

My RV Microwave Is Not Working and Shows No Display or Interior Light
Make Sure Your Microwave Is Firmly Plugged In
Start by checking that your microwave is firmly plugged in. This may seem obvious, but it’s an easy problem to overlook if you’re rushed or in a hurry. If the plug isn’t securely connected, it may be partially disconnected and not receiving enough power. Make sure that the cord is secure and properly connected to both the microwave and the power source. [1]
Check/Flip the Breakers on Your Power Pedestal
If your microwave is plugged in but still isn’t working, the problem could be a tripped breaker. Check and reset any breakers on your power pedestal that may have caused the issue. If you don’t know where these are, check with the park office or look for an information panel near your hookups. [1]
Check Your House AC!
If you’re using a generator to power your microwave, make sure it’s turned on and that the house AC is working properly. If not, try resetting or replacing the fuse for the house AC and check again. [1]
Check the Breakers In Your Power Converter/Breaker Box
If you’re still having trouble, check the breakers in your power converter/breaker box. This is usually located near the entrance door of the RV. Flip any breakers that may be tripped and see if that solves the problem. [1]
Check Your GFCI Outlets and Reset If Necessary
Check any GFCI outlets in your RV and reset them if necessary. These are typically located near the kitchen sink or bathroom, and they help protect your appliances from power surges. If the outlet trips when you plug something else in, it may be part of the reason why your microwave isn’t working. Resetting the GFCI should fix the issue. [1]
Test the Outlet
If the outlet is functional but the microwave still isn’t working, you can test it for voltage by using a multimeter. This will tell you if there’s a power issue that needs to be addressed before your microwave will work again. [1]
Check the Microwave’s Internal Fuse
If you’ve checked all the other possibilities and your microwave still isn’t working, then it might be due to an internal fuse. This is a safety feature that can be tripped in some cases where there has been a power surge or overload. Check the owner’s manual for your specific model to see if this is an option, and if so, how to reset it.
By following these steps and troubleshooting your RV microwave, you should be able to get it up and running again in no time! With some patience and a little bit of know-how, you can avoid the hassle and expense of calling for an appliance repair service. [1]
My RV Microwave Suddenly Turns Off While I’m Using It
Make Sure the Microwave Is Properly Vented
If your RV microwave suddenly shuts off while you’re using it, it could be due to improper ventilation. Microwaves need air to circulate and allow the heat they produce to escape. Without proper ventilation, the machine will overheat and shut itself off as a safety measure against fire hazards.
To properly ventilate your RV microwave, make sure there is at least a two-inch gap between the back of the unit and the wall. If you have cabinets above your RV microwave, leave a minimum of six inches of space between them for air to freely flow. [1]
Your Microwave’s Wattage May Be Too High
The wattage of a microwave is determined by the amount of power it uses when running.
To reduce the wattage, find an RV-specific microwave that uses less energy. [1]
Issue With the Power Source
If your RV microwave is not receiving enough power, it won’t be able to function properly. Make sure the circuit breaker supplying power to the microwave has not been tripped as this can cause a sudden shut down. Additionally, check the plug and cord for any signs of damage such as melted plastic or exposed wiring. [1]
Are You Running the Microwave on Generator Power?
If you’re running the RV microwave off of a generator, it could be overloaded or have an issue with its surge protector. If this is the case, switch to shore power and see if that resolves the issue.
If these troubleshooting tips did not help resolve your RV microwave’s issues, contact an authorized service technician for further assistance. A qualified professional can diagnose the issue and help you get your microwave back up and running in no time. [1]
Are You Plugged Into a 15 or 20-Amp Power Source?
When plugging in your RV microwave to a power source, make sure you are plugged into a 15 or 20-amp outlet. If the wattage was already reduced and the ventilation is up to par, then this may be the issue as microwaves require more amps than other appliances. [1]
My Microwave Runs But Isn’t Heating Food
Broken RV Microwave Door Switch
If your RV microwave runs, but is not heating food, it might be a problem with the door switch. This switch is a small part located inside the appliance that tells the oven when to turn off when you open the door. If your door switch isn’t working properly, then the oven won’t heat up. You can check your door switch by inspecting the wiring that connects it to the oven. If there is any damage, you may need to replace the switch. [2]
RV Microwave Magnetron Needs Replacement
The magnetron is an essential component in the RV microwave. It uses a powerful electromagnetic field to generate microwaves that heat your food. If your microwave isn’t heating up, it could be because the magnetron needs to be replaced. You can test your magnetron using a multimeter. If it fails the test, you should replace the magnetron. [2]
RV Microwave High Voltage Diode Is Worn Out
If your RV microwave isn’t heating up, it could be because the diode is worn out. You can test your diode using a multimeter to determine if it needs to be replaced.
Regardless of what the issue is, it’s important to take your RV microwave to a professional for repairs. They can properly diagnose and repair any issues that you may have. Taking care of your RV microwave will help ensure it runs smoothly for many years to come. [2]
How to replace RV Microwave?
Replacing your RV microwave is a straightforward process. The first thing you will need to do is disconnect the power from the RV and remove the existing microwave. Many RVs have an access panel or hatch on the outside of the rig, which makes it easy to locate and remove the old unit.
Next, you’ll need to measure the opening where your new microwave will go and purchase a replacement unit that fits. Make sure to get one that has the same mounting bracket and wiring configuration as the old one.
Once you have your new microwave, start by connecting the power cables (red/black/white) to their appropriate connections on the RV side of things. Some microwaves come with a template that makes this process easier. Once the power cables are connected, you can use screws to mount the new microwave in place.
Finally, you’ll need to fit the interior trim pieces and make sure everything is secure before reconnecting the power and turning on your new microwave. [2]
Is there a reset button on a microwave?
Yes, there is usually a reset button on most microwave ovens. The reset button can be found on the back or side of the appliance and looks like a small red circle with a triangle inside. To reset your microwave you’ll need to press and hold this button for several seconds until all of the lights turn off and the appliance resets itself. [3]
How do you reset an RV microwave?
If your RV microwave is not working, the first thing you should do is reset it. There are a few different ways to do this depending on the type of microwave you have:
- For built-in microwaves: If your RV has a built-in microwave, unplug it from its power source and leave it unplugged for at least 30 seconds. Then plug it back in and try turning the microwave on again.
- For countertop microwaves: If your RV has a countertop microwave, you can reset it by pressing the “Stop/Reset” button for three seconds or until the light on the control panel turns off. [3]
