Microwave Light Bulb – The Most Reason Why The Microwave Is Not Hot

The high-frequency or light bulb is one of the essential parts of a microwave. It directly affects the method of reheating and cooking food. Therefore, when the sunshine bulb is broken or features a problem, the microwave won’t be ready to heat. This makes many of us feel incredibly uncomfortable.

The explanation for spoilage often causes by the oven operating with high intensity, high power, or heating the food to the utmost for an extended time. The fuse within the furnace was blown at this point, causing the high-frequency bulb also to fail. Thus, the method of heating the food won’t be possible.

In addition, the failure of the microwave to dissipate heat in time when operating also can cause the high-frequency bulb to malfunction. Therefore, if you notice that the device isn’t working correctly, you ought to conduct an inspection to require timely remedial measures.

How To Check Microwave Light Bulb With Simple Steps

When we notice that the bulb isn’t bright or bright but can’t be heated, we’d like to see it immediately. If you’re inexperienced, you’ll ask the way to check Sharp microwave high-frequency balls with these simple steps:

Check with a multimeter

When employing a multimeter, you’ll strictly know if the capacitors and circuits of the high-frequency bulbs within the microwave operate at full capacity. Accordingly, we’ll inspect the subsequent parts:

Microwave transformer

The main structure of a microwave is an isolating transformer. During this transformer, you ought to measure the secondary voltage source as 100V. Including one secondary coil is rectified by high voltage diode. It converts to electricity that goes through DC first. Then run through another capacitor with voltage measured at 2000V. The diodes are liable for rectifying and powering the Magnetron lamp. During the inspection, if it’s dead or not consistent with specifications, it should get replaced.

Microwave light bulb

First, we turn the punch in “X1” form. Then, use the measuring tape to live the two pins of the high-frequency microwave bulb. If the meter has a sign of resistance, the coil is in good working order. And when the meter goes to 0, it can determine that the high-frequency bulb has been damaged.

In case the bulb still shows resistance, please turn the needle 10k consecutively. Continue using one needle to live the foot of the ball, the opposite foot to live the ball wall. If you see the clock hands running, the bulb has an electrical leak. And when the needle value goes to 0, it means the ball remains operating stably.

Check the microwave high voltage capacitor (transformer)

The next step to test microwave bulbs is to work out if the high voltage capacitors and microwave transformers are burnt or dead. At an equivalent time, let’s examine if there’s any damage to the Magnetron lamp. Accordingly, you ought to measure the resistance of the light to the guts. This voltage level fluctuates within the range of two .8 – 3V.

If you’ve got tons of your time, you should check the high voltage fuse connected from the high voltage coil to the capacitor. Just in case everything is ok, remove the lamp and see if the two toroidal magnets are broken or not. Unfortunately, the magnet bar has cracked, we must replace the new light.

Why Does Not The Microwave Light Come On?

Because it is not plugged in

It sounds a touch silly, but did you forget to connect the oven? Or the facility plug isn’t close and loose? Is there a little piece of garbage within the socket? Please recheck the plug, clean the plug carefully, and see if the above condition remains there.

Use your hand to rub from the start to the top of the wire. If there’s an opportunity, use tape to reconnect it carefully, and plug it in to see again.

The lamp within the oven is broken

If the facility cord is standard and punctiliously plugged in, but the oven light still doesn’t light, the lamp could also be damaged; take the oven to a professional place or a service center for repair.

The Reasons Why The Microwave Does Not Heat And The Way To Repair It Reception

The transmitter is broken, causing the loss of microwaves

The principle of the microwave to heat or cook food is because of the high-frequency ball that emits extremely short waves, also referred to as microwaves. When the sunshine within the oven comes on and therefore the dish remains spinning, but the food isn’t heated, it means the microwave is broken due to the broken microwave.


– Damaged high-frequency bulbs are often caused by you leaving the microwave to run at 100% capacity for an extended time, causing the microwave to overheat and not be ready to dissipate heat in time.

– Then, the fuse of the microwave will break to guard the high-frequency ball.

How to fix:

– Unplug the facility cord of the microwave from the socket, open the oven door and remove the food, remove the rear cover of the oven, find and remove the fuse box, remember to go away the wires intact.

– Open the fuse box, then take the two ends of the wire attached to the fuse and use an electrical tester to see if the fuse lights up or not.

– If the fuse is blown, replace it with another fuse of an equivalent type because the manufacturer offers, then put it back in its original position and shut the oven cover.

– Then, once you have replaced or reconnected the fuse. You plug the facility plug, put the food within the oven, then set the capacity, modes, timer, await the time to expire. You’re taking the food out. Finally, If you see that the dish is hot enough, the fuse replacement has been successful.

The part is just too dirty, causing stains to stay to the rock bottom of the oven wall

Any home appliance is going to be dirty after a period of use. If you do not maintain and clean it, it’ll produce unintended damage you don’t anticipate. If the microwave that you use for several months without cleaning, long-term cleaning of drugs from food will accumulate and cling to the rock bottom of the oven wall, preventing waves from emitting, making the oven not hot.

How to fix:

– After completing the cooking process, use a soft cloth soaked in warm water, then clean the oven cavity and oven cover. If the stains are stubborn, you’ll use mild detergents or natural cleaners like lemon, vinegar, etc., to clean.

– Deodorize the microwave: Put 1 cup of fresh juice, microwave for about 3 minutes, then wait a couple of minutes for the oven to chill, then remove the cup of water, then use a clean towel to wash it quickly. and more convenient.

Use food containers that can not utilize in the microwave

Many consumers don’t skill to use. Therefore, the items should be utilized in the oven, resulting in incorrect containers and not promoting the complete function of the microwave.
