Amana microwave not heating. When a problem presents itself in your Amana microwave such as it, not heating, it’s important to troubleshoot the problem and fix any issues that might come up for your Amana microwave oven.
If you discover an issue with your microwave, don’t worry about taking time out of your day to contact a professional! We are here to teach you how to take care of this issue before calling a technician out at all.
Following these steps will help get your Amana microwaves back up and running in no time.
Amana microwave not heating
If you’re looking for help fixing your microwave, then this article is for you. We’ve gathered all the relevant information from numerous resources and are sharing it here in one place so you can simply go through it and be done with the troubleshooting process once and for all. We will structure this article as follows:
Microwaves are used for cooking food over long periods of time. The microwaves combine with water and fat molecules to create heat energy that cooks the food.
The magnetron is the part of the microwave that produces these microwaves by using high voltage, a high-frequency alternating current.
If the magnetron is defective, your microwave isn’t going to heat up. This means that you’ll have to replace it instead of getting it repaired.
Note: A microwave oven can store lethal amounts of electricity in its capacitors even after the power has been turned off, so be careful when repairing it.
Replace Door Switch
When the microwave door closes, the microwave will notice it and deactivate.
if it senses that any of these switches are defective because the next step would be the on-button being pushed, which is like throwing a wrench in the overall operation of your device.
To determine if any of these switches are located within your door or not, use a multimeter to test each of these switches for continuity so you know whether or not they’re needed.
A high Voltage Transformer issue
Microwave ovens can produce a lethal amount of power, which cooks food by using high-frequency electromagnetic radiation. If a high-frequency transformer fires up, it will usually arc and smell like burning plastic.
Microwave ovens have a lot stored inside their capacitors after being unplugged from the wall; so make sure to avoid sparks when entering the microwave under any circumstances because you may get electrocuted.
High Voltage Capacitor problem
If the high voltage capacitor has become defective, there will be no current on the secondary side of the transformer, resulting in a “burned out” high voltage diode.
The microwaves won’t come out, but will only be reflected back into the oven for recycling and never reach the food. If you suspect this has happened – first use a VOM (volt-ohm meter) with a capacitance test function to measure the value of two or three randomly selected capacitor Cs.
Note all readable values! If measurements from several capacitors differ by more than 50%, change every second capacitor at random! This way you have a 50% chance to really fix this grid!
Blown Thermal Fuse
The microwave oven’s thermal fuse will permanently break the electricity to the machine if it senses that the microwave is overheating. To test for this, you can use a multimeter to see whether or not there is continuity in the fuse.
If it is defective and doesn’t have continuity then you will need to replace it. The only way to repair a burnt-out thermal fuse is by replacing it because resetting it won’t work.
(Caution: Make sure that your home’s circuit breaker has been switched off before attempting any repairs!)
Main Control Board fault
There are many components to a microwave oven and they can cause the oven not to work. Fixing some of them is easier than fixing others. By checking the less-complex ones first, you could save yourself a lot of time and money by avoiding having to change the main control board.
If all else fails and you find that no matter what you do, one part after another keeps malfunctioning then it might be best to see if this problem has been thoroughly researched.
Not all replacements need to be done by professionals though so carefully read through the troubleshooting page of your microwave oven manual before deciding to call in an expert.
Thermo protector does not have continuity
If the microwave overheats, the Thermo protector cuts the power. If the Thermo protector trips, the microwave won’t start or heat up.
A multimeter can be used to test for continuity to determine whether the Thermo protector is faulty. In the absence of continuity, replace the protector.
