Kitchenaid Microwave Not Heating

Kitchenaid Microwave Not Heating. In the modern world, there are so many different kinds of technological wonders that have revolutionized how we live in numerous ways, which can sometimes be a stressful thing.

For example, microwaves were invented in order to make cooking quick and easy and thus save us time. We know these microwaves and the delightful foods it cooks for us are very important.

When you’re left with a microwave that isn’t heating up your food like you want it to be because it’s actually broken down completely, you’ll feel a sense of being lost.

Here we discuss some problems with KitchenAid microwaves when they don’t heat.

Defective Main Control Board

It is possible that the main board of the control system is defective. In order to prevent that from happening, check all of the most commonly defective parts prior to replacing them.

As long as you have established that all of these components are working correctly, you should replace the main control board.

Issue With Thermoprotector

As soon as the microwave overheats, the Thermoprotector cuts off the power to the microwave. In the event that the Thermo protector trips, the microwave will be unable to heat up or function properly.

Using a multimeter is the first thing you need to do to determine whether continuity exists. To ensure that there is a connection before you replace that wire, you should first make sure that there is one.

Problem With Thermal Fuse

In the event that the microwave overheats, the thermal fuse will shut it off and cut off the power. The best way to determine whether a fuse has blown is to use a multimeter to test its continuity.

A blown fuse should be replaced immediately if it has no continuity. Unlike the thermal fuse that can be reset, if the fuse is blown you will need to replace it with a new one.

Transformers With High Voltage

In a microwave oven, high voltage is used to cook food through the use of microwaves fired from an antenna into a metal dish. An arched microwave will have a burning smell when the transformer in the microwave breaks down.

This can cause fires, burns, and even death. Since there are unconnected turns between the resonator and the anode of the magnetron, the magnetron has high voltages even when it is not producing microwaves.

Capacitor With High Voltage

The high-voltage capacitor increases the amount of voltage created by the transformer. It acts with a high-voltage diode to smooth and focus this energy into DC current.

If your microwave’s expanding capacitor is burned out, your entire circuit won’t charge as well and your hot plate will overheat. To see if your unit’s HV capacitor is defective, check it with a VOM that has a leak tester or capnometer feature.

Defective Magnetron

This is a result of the magnetron being controlled by the microwave’s high voltage and current, which in turn produces the frequency which cooks your food.

However, if the microwave doesn’t have the necessary power, the magnetron won’t work. In the event a magnetron burns out, it cannot be repaired, so if a burn out occurs, it must be replaced entirely with a whole new magnetron with a similar voltage and current rating.

Faulty Door Switch

The majority of microwave ovens have three or four buttons on the door. It is imperative that the door switches in the microwave door are actuated in a sequence to ensure a proper close of the door when the door closes.

If a door switch fails, you will experience a failure in the microwave and it will not start or heat. If you are unsure whether any of these door switches are defective, you can use a multimeter to test each one on the basis of continuity. If any of these switches is not functioning properly, it should be replaced.

Diode Malfunction

A diode passes DC current in one direction but prevents the conduction of electricity in the other direction. This makes a diode an essential component when building microwave ovens.

The power transformer, which is responsible for converting 120V A/C voltage to the high voltage D/C needed by the magnetron to heat food, sends its current through a rectifier that converts AC to DC.

Unfortunately this process also creates nasty spikes and transients that can destroy the resistor.

Therefore, it is necessary to install diodes in series with each of the transformer’s secondary windings as well as all moving-coil components. When replacing these diodes make sure you use only rated diodes and be sure they are installed properly.
