New dryer blows circuit but not the dryer circuit.

Hi @greg17520

Does it blow if you just run the dryer on "cool" i.e. no heat?

Usually with most dryers the two power supplies are split.

One supplies the motor and controls and the other the heater element.

Sounds like there may be a wiring error from or in the premise's power box.

One of the 30A breakers may not be supplying power to the dryer but the 15A breaker that blows does.

When the 15A breaker blows does this affect the function of the lights or power outlets in the bedroom?

Unusual that there's a dedicated breaker for a bedroom if this is what you meant - normally for lights there's one breaker for the particular premises and for general power outlets they usually have two breakers that between them supply all the outlets for the particular premises. Higher power appliances e.g. air con and dryers etc have their own dedicated breaker(s) although sometimes dryers can be connected to an existing wall outlet supply with an added supply run in especially for it. - i.e. the outlet socket is changed to a either a 3 or 4 pin socket to suit the dryer power cord plug.

What is the model number of the dryer?
