After replacing the belt in a dryer, you should run it for a short test cycle to ensure that everything is working properly. Typically, running the dryer for about 10 to 15 minutes on a low or medium heat setting should be sufficient for this test.
During this test run, monitor the dryer closely for any unusual noises or vibrations, which could indicate improper installation or other issues with the new belt. If everything appears to be functioning normally and the drum is rotating smoothly, you can then use the dryer as you normally would for your laundry needs.
Keep in mind that this is a general guideline, and the specific instructions may vary depending on the dryer model and the manufacturer's recommendations. Always refer to the user manual or any instructions provided with the replacement belt for the most accurate guidance.
If you're unsure or encounter any difficulties during the installation process, it's best to seek the assistance of a professional appliance repair technician to ensure the belt is properly installed and the dryer is safe to use.
