Troubleshooting My Philips Airfryer makes a noise If you notice noise coming from your Philips Airfryer, there might be some possible causes. See how to resolve this below. The fan is on If the noise you hear sounds like a fan rotating very fast, this is normal. Your Philips Airfryer has a fan inside which helps keep its internal parts cool while the appliance is on. This noise can be up to 65 db., or as loud as the noise an average vacuum cleaner would make. In this case, do not worry, there is nothing wrong with your Airfryer. There is something loose inside If the noise is louder or different from the usual sound you hear from the fan (such as a fluttering or shuffling noise), then there is something loose inside your Airfryer. In this case, please contact us.
