Jenn Air Microwave not heating

Jenn Air Microwave not heating. If a microwave oven is acting as though it’s working, but the food on the screen never warms up, one possible explanation may be that the microwave isn’t terminating its current.

A diode allows electrical energy to flow inwardly only in one direction.

If a diode experiences issues, then it may mean that there’s a short circuit present which would allow the current to move both ways or not at all, depending on its design.

Here we will discuss some common issues and solutions for the Jenn Air Microwave, not heating.

The door switch is defective

Most microwaves have several door switches. As soon as the microwave door closes, these switches begin to move, making them respond in succession until the food is all ready for you to enjoy.

If any of these important parts break down, then your dish won’t be fully prepared as it would under normal circumstances.

Make sure you take a closer look by using a multimeter in order to check whether any of them are up for the job or not.

If one of those little fellows would turn out to be useless, don’t let it get the better of you! Just let our licensed technicians upgrade it immediately so that you don’t have another bad day ahead.

Diode fails

The diode is a two-lead semiconductor device used to block direct current while passing alternating current, thereby allowing the alternation of the current as it passes through.

Diodes are connected in series with transformers and magnetrons. The diode allows power to pass through when it is in one direction but blocks the reverse voltage when it tries to enter in another direction.

High voltage capacitor works

The high-voltage capacitor replacement is necessary to repair your microwave, which can stop functioning properly if the capacitor goes bad.

Replacing this component will fix your microwave and make it work again. To determine if you need to replace the high voltage capacitor, you should check its value using an ohmmeter.

High voltage transformer fails

Microwave Ovens use magnetrons to cook the food inside. These are expensive in nature, and can’t be replaced. So if the microwave stops working for some reason, it is better to call a technician instead of trying to repair it yourself.

When the Magnetron has gone bad and the microwave doesn’t work at all, there will be an arcing smell from the high voltage transformer of the oven that is damaged or burnt out.

This could lead to further damage/burning as well, hence is better not to try at home unless expert supervision is available.

Let a technician come and check out your oven before continuing with any repairs and always keep yourself away from the high voltage capacitor.

Thermoprotector not working

The Thermo protector is a device designed to protect the microwave by turning off the power if it overheats. This is a pretty great feature.

However, if your device has no way of protecting itself from getting too hot it’s still going to work, but then offer little protection from running hot. In order to fix this, you’re going to want to make sure that the Thermo protector itself is working properly.

After you have checked your Thermo protector you will most likely find that it needs replacing which makes sense in your situation since you tried using a regular vacuum cleaner and it didn’t work, whereas our vacuum claims it can fix this issue without having to replace any parts at all.

The main control board might be defective

A microwave is a really nifty invention, but they often operate using high voltages. Safety regarding working with this kind of technology must be taken very seriously.

If you suspect the main control board is faulty, check to see if there are any other issues that might need addressing like loose wires or a faulty button.

If it appears it needs replacing, you can save yourself some money by hiring an electrician to survey these problems for you and fix them accordingly.

Replace the main control board if the problem persists after checking all of the more commonly defective parts.

Thermal Fuse overheats

A thermal fuse will cut off power to a microwave if there’s a malfunction. You can test the continuity of the thermal fuse with a multimeter to determine if it needs to be replaced.

Fuse replacement is necessary if continuity is not present. Thermal fuses cannot be reset, so if they blow, they must be replaced.

 A magnetron is burned out

The electromagnetically-excited, high-frequency radio wave generator is what cooks the food. If the magnetron malfunctions, then the microwave oven stops heating.

The magnetron itself cannot be repaired it must always be replaced when broken/burned out.
