You can test if your microwave is heating properly by heating a cup of water in a microwave-safe dish for about 30 seconds. Carefully test the water to see if it has heated. If it isn't hot, repeat the process. If it still isn't hot after a few attempts, it is not heating properly.
If you're not sure if your microwave has been damaged, you can test it by putting a microwave-safe container with water inside and then running it for a minute. If the water isn't hot, the microwave has been damaged. If the microwave still heats, it hasn't been damaged and can still be used safely.
The microwave cavity and door are designed to trap the wavelength of 2,450 MHz. It does not block the other waves that operates in the different operating frequency likes the cell phone. Using the cell phone testing is not a proper way to detect the microwave radiation leakage.
Like many other devices, microwaves have a thermal fuse to keep the appliance from overheating. If this fuse is blown, the microwave won't power on. Microwaves also have a ceramic fuse. This is usually inside the rear panel, near the power cord.

Plate Not Turning
Probably the most common issue of any microwave is when the plate doesn't turn. The turning plate helps cook and reheat your food evenly, so it's a major headache when it's not working. Usually, the problem could be from something obstructing the spinning assembly.
With normal usage for an average family and good maintenance, a microwave often lasts for 7 to 8 years. If the microwave is used less frequently by a single person or a couple and is well-maintained, the lifespan can increase to up to 10 years.
Testing for leakage
Testing is to be performed by placing a large mug of water in the microwave oven, whilst putting it on maximum power for a minute. The calibrated microwave leakage tester will then be used to scan door seals and the front glass.
Place a glass bowl (preferably a 2 quart glass measuring bowl) filled with 1 quart of water in the center of the Microwave Oven cavity. The water temperature must be between 59 to 75 degrees Fahrenheit (15 to 24 degrees Celsius). Heat the water for exactly 2 minutes and 30 seconds on the High power level.
The detection of the microwaves is operated through two principal sensor elements: an antenna and a receiver. The antenna collects the incoming radiation and the receiver measures the collected electric signal.
So to answer the question, 'do I have to get my microwave PAT tested? ' – it's not a legal requirement, but it's one of the best ways to make sure your microwave meets health and safety guidelines.
One of the most common issues with a malfunctioning Magnetron is the lack of heating. If your microwave is running but not producing heat, it could be due to a faulty Magnetron, burned-out filament, or a malfunctioning high-voltage diode.
If the cost of repairing a microwave comes close to or exceeds the price of a new one, it might make more financial sense to replace it. However, if the costs of repairing are relatively low and the microwave isn't too old, it could be worth repairing the microwave.
On average, microwaves last 7-8 years.
Unusual Noises and Strange Smells
If your microwave has started emitting unusual noises or strange odors during operation, it's time to be concerned. Unusual sounds could indicate issues with the motor, while strange smells might suggest electrical problems or internal component damage.
Reset the microwave.
To reset the microwave, unplug it or power cycle at the circuit breaker for 60 seconds.
Smoke, sparks, and burning smells.
These are signs of a serious and urgent problem. Stop what you're doing, and turn off and unplug the microwave immediately. There's no going back if you see smoke or sparks, or smell something burning. Your microwave is failing, and it's time for a replacement.
These are safety red flags, and fixing them might not be worth the hassle — or the risk. Faulty Magnetron: The magnetron is the part that heats your food. If it goes bad, the cost to replace it can be almost as much as buying a new microwave.
Reasons: Control panel issues: A malfunctioning control panel can prevent the microwave from responding to your inputs. Fuse problems: Blown fuses can interrupt the power supply to the microwave. Power cord damage: A damaged or disconnected power cord can prevent the microwave from receiving power.
Disconnect the microwave carefully from its power outlet. While unplugging the microwave make sure that your hands are dry. Do not touch the switchboard or plug in the microwave with wet hands. Keep the microwave unplugged for 5-10 minutes.
