Whether you’re warming up last night’s leftovers or defrosting ground beef for tonight’s dinner, your microwave saves you from wasting a large amount of time in the kitchen. Unfortunately, this useful tool can also cause you problems when it begins to emit unfamiliar noises. While many people avoid microwave repair by purchasing a new appliance at the first sign of trouble, taking the time to troubleshoot the device may be the better option for you and your wallet. Listed below are 4 reasons why your microwave may sound a bit under the weather.

Turn Table

Like most motors, age and use can eventually cause your turn table motor to malfunction. Luckily this issue is more common than most, and a repair technician should have no problem pinpointing the defect and fixing it.

Exhaust Fan

If you have an over the oven microwave installed, it most likely has an exhaust fan to help ventilate your kitchen. The fan can at times create a humming noise that might cause you some concern. You can distinguish this noise from others by turning the exhaust fan off and listening to see if the sound continues. If it stops, the motor on the exhaust fan is probably the cause of the humming. This sound usually does not require attention, but if it continues to grow louder when you operate the fan, you may want to call a repair company.

The Magnetron Tube

A growling or high-pitched sound coming from your appliance when its cooking is a good indication the magnetron tube is failing. The magnetron in your microwave is responsible for creating the frequency that cooks your food. In good condition, this device operates silently. Unfortunately, those unfriendly noises your hearing from your appliance commonly indicate the magnetron is burning out. If you choose to replace the part, you will have to call a professional repair technician.

Stirrer Motor

The stirrer is a metal blade that distributes the microwaves energy by rotating. This action is what causes your food to cook evenly. After years of use, the stirrer motor becomes worn and emits a grinding noise. You will need to replace the motor to eliminate this unnerving sound from infiltrating your kitchen.

Before you retire your microwave, take a moment to troubleshoot its malfunction. You may be surprised to find that fixing the appliance is cheaper than buying a poor quality replace that will likely breakdown in the near future.
