1. power failure: check whether there is electricity in the power socket, and make sure that there is nothing wrong with the socket and plug-in. You can try to check the power supply of the socket with other electrical equipment. If other electrical equipment works normally, there may be a problem with the power cord or power interface of the sausage roaster.

2. Machine failure: It may be that there is a problem in the internal circuit connection of the sausage roaster, which leads to the button not contacting the power supply correctly. You can try to press the button several times to see if there is current or if the power indicator is on.
