This is actually quite a common issue and normally can be resolved with some basic troubleshooting.
The first question relates to the age of the dryer, or how long you've been using the dryer on it's current circuit. If it is a new dryer and/or you have recently moved the dryer to a new location or circuit, then it's most likely an issue with the circuit you are using your dryer on. Dryers do draw a lot of power during use and depending on how many other appliances are on the same circuit, it can cause the circuit breaker to trip. In this scenario, there is nothing wrong with your dryer, but you will need to look at either moving the dryer to a different location/circuit or removing other appliances running on the same circuit. If you don't want to move the dryer to a different location, you may also be able to stop this from occurring by not running another appliance at the same time (i.e. a washing machine). Alternatively, you will need to have an electrician look at upgrading the circuit to accomodate the combined load.
If it is an older clothes dryer, the issue may relate to a component failure such as the heating element or drum motor. Please advise our Customer Care team in this situation and we can work through your options to get this fixed.
