If your old GE microwave started making loud noises after cleaning it, there could be several possible reasons for this issue:
Residue or debris: During the cleaning process, some water or cleaning solution might have gotten into the internal components of the microwave, leading to the creation of steam or causing residue to build up in places where it shouldn't be. This can result in unusual noises as the microwave operates.
Loose parts: Cleaning might have inadvertently caused some internal components to become loose. When the microwave is running, these loose parts can rattle or vibrate, causing the loud noises.
Wear and tear: Over time, microwaves can experience wear and tear, especially if they are older models. Cleaning could have exposed pre-existing issues that were not apparent before, leading to the loud noises.
Incorrect reassembly: If you disassembled any parts of the microwave during cleaning, it's possible that they were not reassembled correctly. Improper reassembly can cause parts to rub against each other, creating the noise.
Fan issues: Microwaves have internal fans that help keep the components cool during operation. Cleaning might have affected the fan's performance, causing it to make loud noises when running.
Electrical or technical problems: It's also possible that cleaning was coincidental, and the loud noises are due to an electrical or technical problem with the microwave.
To troubleshoot the issue, you can try the following steps:
Inspect for residue: Check the interior of the microwave for any leftover cleaning solution, water, or debris. Wipe down the interior thoroughly and ensure it's dry before use.
Check for loose parts: Carefully listen to the noise while the microwave is running and try to identify any specific areas from where the noise is originating. If you suspect a loose part, it's best to have the microwave serviced by a professional technician.
Reassemble properly: If you disassembled any parts during cleaning, ensure they are correctly put back together according to the manufacturer's instructions.
Unplug and reset: If the microwave continues to make loud noises, unplug it from the power source for a few minutes, then plug it back in. This can sometimes help reset the microwave's internal electronics.
If the problem persists or if you're unsure about performing any troubleshooting steps yourself, it's best to contact GE customer support or a professional appliance repair service to inspect and fix the microwave. Remember to prioritize safety and avoid using the microwave until the issue is resolved.
